1.0 INTRODUCTION

1-1. REFCON REFRIGERATED CASES: Refcon cases; refrigerated and heated; are distinctively designed to accommodate a wide variety of food display

applications and products. Refcon refrigerated cases are offered in either self-contained or remote models.

1.1A SELF-CONTAINED MODELS: Self-contained cases include a factory installed compressor/condensing unit to provide the designed refrigeration requirements. Self-contained models typically are built

with a factory installed electric condensate evaporator, or in some instances, the case may be built for use with a plumbing floor sink, or

drain (Provided by others).

1.1B REMOTE MODELS: Remote Cases are constructed to utilize a

refrigeration source that is external to the case. It is important that the

external refrigeration source(s) have the correct refrigerant type for the fixture(s) purchased, and the refrigeration capacity is sufficient to

maintain the case(s) temperature. Remote cases are typically built for use with a plumbing floor sink, or drain (Provided by others).

1-2. CASE LOCATION: For proper case operation, installation in an air-conditioned space maintained at a maximum ambient temperature of 75° F and a relative humidity of 55% is mandatory. Do not install the refrigerated

case(s):

• In an area that has excessive air movement; i.e. close to external doors or

from air-conditioning vents.

• In a location that may have excessive heat, such as near windows that get direct sun.

• Near any other heat producing equipment or lighting.

• Self-contained cases must be installed such that airflow is not obstructed to

the condenser air intake and exhaust sections. Ensure the area of free airspace openings is equal to, or greater than, the louvered condenser section of the self-contained case.

1-3. PROPER CARE: As with any display fixture, Refcon refrigerated cases require routine care and maintenance. Requirements for the maintenance and cleaning

are contained in the manual and must become a regular part of the operation of the unit at all times.

1-4. ASSISTANCE: Should there be the need for additional, or service related assistance, please feel free to contact Refcon at (201) 750-5060.

2.0 INSTALLATION

2-1. INTRODUCTION: This section provides the installation and unpacking instructions for Refcon refrigerated display cases.

2-2. SHIPPING DAMAGES: Thoroughly check the received Refcon

equipment for possible transportation damages. If such damage is established, a claim must be filed with the carrier immediately and any

apparent damage must be stated on the freight bill or carrier may refuse the claim. Retain all packaging for carrier’s inspection.

If the damage is established only after equipment is uncrated, the

purchaser must file an immediate claim with the carrier and request in writing an immediate inspection. All packaging must be retained for

inspection. Request for inspection must be made within 10 days after shipment is received.

2-3. SHORTAGES: Received equipment should be checked for possible shortages. Should such shortages exist, contact Refcon and/or the carrier

immediately. Refcon will only consider all shortage reports within 10 days after equipment was received at destination.

2-4. PRIOR TO INSTALLATION: Verify the intended final case location is suitable for proper operation. As mentioned it section 1, it is imperative

that the placement of Refcon equipment is not located where there is excessive heat from sunlight, heating units and/or there is excessive air

movement nearby since this will impair the intended performance of the

case(s).

Only qualified Electrical, Mechanical, and Refrigeration Technicians should perform the installation of the

refrigerated cases in accordance with all applicable National and Local codes.

Examine Fixture For Any Shipping Damage. Report Any Such Damage to the Carrier for Adjustment. All

Equipment is Shipped FOB from the factory and filing claims for damages, which occur during transit, is the

responsibility of the Purchaser.

For proper case operation, installation in an air-conditioned space maintained at a maximum ambient

temperature of 75° F and a relative humidity of 55% is mandatory.

Page 4 October 2010

2.0 INSTALLATION (Continued)

2-5. UNCRATING INSTUCTIONS: Move the fixture as close as possible to

its permanent location. When ready to uncrate, carefully remove all crating above the pallet. Loosen the plastic dust cover from the pallet

but leave cover over the case in order to protect it while removing the

case from the pallet. Carefully slide it off the pallet.

2-6. UNPACKING INSTRUCTIONS: Carefully remove all separately packed

accessories such as lights, shelves, etc. from the fixture and place them in area where damage will not occur.

Cases are TOP HEAVY. Take special care in lifting and/or moving cases, or personal injury could

result.

Page 5 October 2010


2-7. EXCESSIVE EXTERNAL LOADS: Do not place any heavy objects or walk on top of the cases. Refcon displays are not designed to support

excessive external loads.

2-8. LEVELING CASES: After locating the case in position, level the case by

adjusting leveling feet or shimming as required.

Use of 4’-5’ level is recommended. Level both left to right and front to

back.

Standing or walking on top of cases may cause personal

injury or property damage to the case.

For Cases equipped with lift up glass, it is extremely

important the fixture is set perfectly level.

To ensure proper operation of the refrigeration system

and the correct drainage of condensate, make sure that

all cases are installed level.

Standing or walking on top of cases may cause personal

injury or property damage to the case.

Page 6 October 2010


2-9. POCKET DOORS: Cases with pocket doors must be set properly in order for pocket doors to operate properly. Some adjustment to doors maybe

required after installation. (This is the installers’ responsibility).

2-10. CASE LINE-UP: All cases are set up in the factory in order to assure proper alignment in the field. In order to properly line-up and level

2-10a. Find the highest part of the floor under the cases.

2-10b. Start leveling from the high point and continue through the rest

of the lineup.

2-10c. Fasten the cases together with the connection hardware

included.

For Cases equipped with pocket doors, case must be square and level for pocket doors to operate properly.

Page 7 October 2010

Condensate Evaporators Operate At A Very High Temperatures and Should Never Be Touched While

Operating. Personal Injury or Burns May Occur.


2-11. CASE DRAINS: Remote refrigerated cases are typically shipped with a P-trap drain. Field extensions need to be connected and routed to the

nearest floor sink, or floor drain. Ensure the trap is installed correctly and the extended condensate line is pitched towards the floor drain.

For self-contained cases utilizing a floor drain, follow the same directions as for a remote case.

For cases equipped with a condensate evaporator, the condensate trap and drain is factory installed.

Ensure all national and local codes are followed for the condensate drain piping materials used and the final

indirect waste connection at the floor drains has the correct air gap distance.

Page 8 October 2010

Remote are shipped with a Nitrogen holding charge. Be sure to relieve pressure carefully.


2-12. ELECTRICAL: Electrical connections can be made within the power supply

junction box at the case. Voltage requirements can be verified by checking the

data tag of the case. ONLY qualified electrical contractors should do electrical installation work. In all instances, the case electrical power supply must comply with all NEC and local codes. It is imperative all cases are properly grounded.

Verify all case electrical terminations are secure, connections can sometimes loosen during shipment.

2-13. REFRIGERANT PIPING: Remote refrigerated cases have stubbed

connections (liquid and suction) for refrigerant piping. Review case fact sheet to determine the appropriate location to install refrigerant piping. Remote cases

are shipped with a Nitrogen holding charge. Be sure to relieve pressure carefully. Use care when brazing, as damage can occur to valves and controls if overheated. While brazing piping always use nitrogen to keep contaminants

from forming inside the refrigeration piping. Ensure all refrigerant piping is properly sized for the associated load and temperature conditions required.

Properly insulate suction lines to prevent sweating. Keep refrigerant piping away from condensate evaporators (if equipped).

2-14. SHELVING:

2-14a. Glass Shelves: Glass shelves are protectively wrapped and shipped within the case.

2-14b. Non-Glass Shelves: Stainless steel shelves are shipped in place with padding and blocking to avoid damage during shipping. Verify

padding and blocking is removed prior to loading shelves.

2-15. DOORS: Some cases are equipped with rear sliding doors. If the doors are

shipped inside the case, remove the protective coverings from the doors and then push the top edge of the doors up into the top track so that the bottom of

the doors can clear the bottom track. Push the bottom door section onto the bottom track. Verify doors slide easily side to side.

Cases Must Be Properly Grounded. Failure to Properly Ground the Electrical Case May Result in

Personal Injury Or Death.

DO NOT modify plugs in any way to fit into outlet

receptacles.

Page 9 October 2010


2-16. LIFT-UP GLASS: Some cases are fitted with front lift up glass. Extreme care

should be used when opening and closing the lift-up glass assemblies. Do not

force, or quickly open/close the glass, as damage can be done to the lifting support arms. The glass is installed at the factory with the case set level but some field adjustments maybe required. (This is the installers’ responsibility).

2-16a. To avoid any damage, please do the following prior to completely raising the glass:

i. Case must be square and level

ii. Slowly raise and lower the glass 6 times to a height of 6 inches.

iii. Slowly raise and lower the glass 6 times to a height of 12 inches

iv. Slowly raise and lower the glass 6 times to the fully open position

2-16b. If further adjustment is required after verifying the cases are level,

please follow the instructions below:

i. Ensure two people are available to make glass adjustments. One

person must always be holding the glass.

ii. Lift up the glass to the highest position.

iii. Loosen the set screws on the glass clamping mechanism.

It is especially important that cases fitted with lift-up glass be installed completely level.

Page 10 October 2010


iv. Slide the glass, left or right, until the glass is even. Ensure the glass is correctly recessed in the clamping mechanism.

v. Tighten the set screw first at either the left or right sides. Ensure the glass is held firmly at the opposite end of where the tightening is started.

vi. Securely tighten all remaining set screws.

vii. Lower the glass into position and check alignment.

viii. If necessary, repeat this process until the glass is completely level.

Necessary adjustments to glass require 2 persons.

The glass must be securely held at all times during adjustment.

3.0 OPERATION

3-1. REFRIGERATION SYSTEM: Refcon’s remote and self-contained cases use

either forced or gravity air circulation systems for cooling (depending on model).

The refrigeration system consists of an all copper tubing evaporator coil with aluminum fins and a thermostatic expansion valve designed for the specific case application. Self-contained models include a matched hermetic condensing unit

for long life and operating efficiency.

3-2. REFRIGERATION CONTROL:

• Remote cases: Can be controlled through several methods:

o With No Controls. This version is intended for installation with a parallel

compressor rack (Supplied by others) or single compressor system. In this instance, the necessary temperature and defrost controls need to come from the associated compressor system equipment.

o Optional Thermostat This version controls the case through an optional thermostat and liquid line solenoid valve. Defrost is controlled by other

means. (Supplied by others)

o Remote Refrigeration Control Package These cases are controlled through a micro-processor based controller tied to a liquid line solenoid valve. The

controller controls case temperature, timed defrost initiation and temperature defrost termination

• Self-Contained cases: These cases are controlled through a micro-processor based controller tied to the condensing unit. The controller controls case temperature, timed defrost initiation and temperature defrost termination.

4.0 MAINTENANCE

4-1. CLEANING: Frequently clean ALL surfaces.

4-1a. GLASS

In cleaning windows to remove soil and grease use an alkali, such as ammonia

or baking soda or washing soda.

To remove hard water deposits and some soils, use a weak acid such as vinegar (a strong acid would etch the glass).

Never combine an acid and an alkali to clean glass. One partially neutralizes the

other and you waste these neutralized materials. Thus do not mix vinegar and ammonia; use one or the other in your water solution to get the full effectiveness of the one product used.

Be careful not to drip alkaline or alcohol solutions on painted or varnished

woodwork as it can damage the finish. Wring out a cloth, sponge, or chamois almost dry before wiping the glass

surface. Dry the wet surface with paper towels, window wipes, or a chamois. Try not to drip cleaning solution on woodwork.

4-1b. STAINLESS STEEL

Known for its ability to be a clean surface that resists corrosion and rust. Dirt, dust and grime, however, put stainless steel at risk for corrosion and rust.

Routine cleaning can be accomplished by using warm water and a cloth. Dry

with a towel or cloth to prevent water spots. Wipe in the directions of the polish lines.

For cleaning that needs more power, mild detergent(dish washing liquid) and warm water can do a great job without damaging the stainless steel. Rinse the surface thoroughly to prevent staining and spotting. Towel dry to prevent water

spots which can be caused by minerals in water.

Fingerprints are one of the biggest complaints about stainless steel, but can be

taken care by using glass cleaner or household ammonia. Rinse thoroughly and towel dry.

Turn off all power witches prior to cleaning the case to

prevent electrical shock.


4.0 MAINTENANCE (continued)

For staining or scratching, or to polish stainless steel, a stainless steel cleaner may be a good option. Some of these cleaners and polishes can help minimize scratching and remove stains and can polish stainless steel surfaces nicely.

Read the directions on the stainless steel cleaner and test in an inconspicuous spot. Rinse thoroughly and towel dry.

� Painless Stainless

4-1c. LEXAN™

Cleaning Instructions

Wash using a mild soap or detergent and lukewarm water, using a clean sponge or a soft cloth. Rinse well with clean water. Dry thoroughly with a chamois or moist cellulose sponge to prevent water spots. Do not scrub or use brushes on

this product. The following cleaning agents have been found compatible with LEXAN™:

� Joy* � VM&P grade Naphtha

� Top Job* � Palmolive Liquid** � Windex with Ammonia D***

*Registered Trademarks of Procter & Gamble.

**Registered Trademark of Colgate Palmolive.

***Registered Trademark of the JohnsonDiversey Consumer Branded Professional Products.

Minimizing Hairline Scratches Scratches and minor abrasions can be minimized by using a mild automobile

polish. It is recommended that a small area be tested with the product selected following the manufacturer’s recommended instructions prior to use on a

complete window. Listed below are three products marketed to polish and fill scratches:

� Johnson Paste Wax

� Novus Plastic Polish #1 & #2 � (Novus, Inc., Minneapolis, MN)

� Mirror Glaze Plastic Polish (M.G. M10)

� (Mirror Bright Polish Co., Pasadena, CA)

DO NOT use abrasive or highly alkaline cleaners

NEVER scrape LEXAN™ with squeegees, razor blades or other sharp instruments

Benzene, gasoline, acetone or carbon tetrachloride should never be used

DO NOT clean LEXAN™ in hot sun or at elevated

temperatures


4.0 MAINTENANCE (continued)

4-1d. ACRYLIC (Plexiglas)

Cleaning Instructions

The Number 1 Problem with acrylic is the use of incorrect cleaners. Do not use cleaners containing ammonia. Cleaners such as Windex or 409 will harm your

new piece of acrylic. Use only products specifically recommended for cleaning acrylic such as Novus #1, or Brillianize, and a soft cloth. Never use a dry cloth

or your hand to clean your acrylic! This rubs the dirt and dust INTO the acrylic as much as it rubs it OFF. First, blow the dust or dirt off, or use water and a soft

cloth to float the dirt off. Then use a recommended cleaner to complete the job. Note: a mild solution of dish detergent and warm water takes off stubborn dirt easily without harming the acrylic if you've run out of Novus #1 or Brillianize.

4-1e. DuPont™ Corian®

Routine Care of Your Corian® Countertop

There are three types of Corian® countertop finishes: matte/satin, semi-gloss

and high-gloss*. Most countertops are finished with a matte/satin finish. All Corian® sinks have a matte/satin finish. (*Contact your local Corian® sales expert if you are uncertain what type of finish is on your countertop.)

A KEY TO KEEPING YOUR COUNTERTOPS LOOKING GOOD IS TO THOROUGHLY RINSE AND WIPE COMPLETELY DRY AFTER CLEANING

Preventing Heat Damage

While Corian® is heat resistant, as with all countertop materials, it is important

to minimize direct heat exposure to protect your surface and investment.

DO NOT PLACE HOT POTS, PANS, ETC. DIRECTLY ON THE COUNTERTOP

SURFACE.

Always use heat trivets or hot pads when placing hot objects on any surface. Always use a trivet under portable heat generating appliances such as a toaster

oven. Allow cookware to cool before placing it into a Corian® sink.


4.0 MAINTENANCE (Continued)

To enhance the gloss level on semi-gloss and high-gloss finishes, use a

countertop polish such as Countertop Magic®, Hope's Countertop Polish® or

Enhance Countertop Polish®.

Cleaning All Finishes

Most dirt &

residue

Use soapy water, ammonia based cleaner (not window cleaner),

rinse and wipe completely dry. Commercially available solid surface

cleaners, such as Clean EnCounters® will also work well.

Preventing

hard water

marks

Rinse and wipe completely dry after cleaning; clean up spills before

they dry.

Removing

hard water

marks

Use a cleaner formulated for removing hard water marks such as

CLR or Lime-A-Way.

Difficult

residue

Spray residue with Deep Cleaner for DuPont Corian® from Stone

Care International. Follow instructions on the bottle. Wash area

with soapy water, rinse and wipe completely dry. If residue

persists, follow steps below for removing dulling film.

Disinfecting Occasionally, wipe surface with diluted household bleach (1 part

water/1 part bleach). Rinse top thoroughly with water and wipe

completely dry.

Avoid getting the bleach solution in your eyes or

bare skin. Always follow the bleach manufacturer's

safety instructions when working with bleach.



4-1f. CAESARSTONE

Its hard, nonporous surface makes it simple to clean. In most cases, soap and

water or a mild detergent is all that is required to maintain its luster. If necessary, a non-abrasive cleanser such as Soft Scrub Liquid Gel with Bleach or Comet Soft Cleanser Cream With Bleach can be used along with a non-scratch or

delicate scrub pad such as blue Scotch-Brite sponge. Adhered materials like food, gum, or nail polish can be scraped away with a plastic putty knife; any

marks left by the blade can be removed with Soft Scrub Liquid Gel and a blue Scotch-Brite pad. Thoroughly rinse the surface with clean water to remove residue.

While CaesarStone does not require sealants or waxes to maintain its luster,

occasional polishing with Soft Scrub Bleach Gel or Comet Gel will keep the quartz surfacing looking its best.

HONED finishes will require more daily maintenance than polished finishes. Since there is more exposed surface area with honed finishes, metal marks,

finger prints and other signs of daily living will show on honed material. Most of these marks can be easily removed with little effort and non-abrasive cleaning products such as Soft Scrub Liquid Gel. For tough stains, work the area with a

blue Scotch Brite pad.

4-1g. GRANITE

Soap and water will clean up most stains but leave a soap film behind over time

that the granite cleaner will easily remove.

i. Spray a light mist of stone cleaner over the area to be cleaned.

ii. Let the product sit for approximately 30 seconds.

iii. Scrub with a sponge.

iv. Buff the surface dry with a clean white cloth or paper towel.

Granite stains! Clean up spills promptly, before they soak into the granite and become permanent.

Granite can be sealed so it is maintenance free and you don’t have to wipe up

spills.



4-1h. RICHLITE

Richlite surface is a durable, attractive material designed to stay beautiful for

the lifetime of your kitchen, bath or office space. A simple wipe up with a damp

sponge on a regular basis will maintain its beauty. Alkaline soap such as regular

dish soap will gradually dull the surface. Howards’s Naturals Wood Cleaner and

Polish will lightly renew the luster if used on a regular basis. Richlite

recommends finishing the surface with Richlite Enhancer to provide a rich,

polished finish that requires minimum care.

Removing Stains

Generally speaking, Richlite resists stains quite well. As with most any material,

there is a potential for some staining. With stubborn stains, try a nonabrasive

household cleaner.

Repairing Scratches and Burn Marks

Richlite is extremely dense and durable. The material resists scratches and

burns but, like most surfaces, can potentially be damaged by cutting directly on

the surface or setting a hot frying pan on the surface. Richlite recommends the

use of cutting boards, hot pads and trivets to protect the surface from potential

damage.

Before refinishing their countertop, please seek the advice of the dealer or

fabricator who installed the counter. In most cases, it is preferable if the

installer refinishes the surface. Light scratch marks and burn marks can be

refinished using a Scotch-Brite® pad (#7447/Red Color). It is important to

note, the refinished area will noticeably lighten compared to the surrounding

surface area. Richlite surfaces are made of paper which, like wood, patinas – or

darkens – over time, especially in the lighter colors such as Baguette. The area

will eventually patina and match the remainder of the counter surrounding it. In

order to avoid affecting one spot, lightly refinish the entire section of the

counter.

General Precautions

Richlite countertops are stain resistant to nearly all kitchen related substances

with the exception of some raw meat juice (such as liver), high-alkaline fruit or

vegetables (such as papaya and red beet), and high-alkaline soaps (such as

automatic dishwasher powder and oven cleaners) when left in contact for a

prolonged time.



The lighter colors in the Richlite color range will show stains more than the darker colors. Additionally, grout (which is a high alkaline product) will lighten darker-colored Richlite counters and darken the lighter tones. Cover the surface with a protective sheet when installing tile around countertop areas. Avoid using bleach products or abrasive powdered cleaners. It is good to avoid using the abrasive side of sponges as this may also scratch the surface of a Richlite countertop.
