MODEL DESCRIPTION

The GSVM open vertical merchandiser offers versatility in the display of medium temperature

(32º F to 41º F) products such as dairy products, prepared salads, pizza and fresh entrees that are pre-chilled in a cooler. Carefully read and follow the instructions prior operating the merchandiser.

UNLOADING

Unloading from Trailer:

Lever Bar (also known as a Mule, Johnson

Bar, J-bar, Lever Dolly, or Pry Lever)

Move the merchandiser as close as possible to its permanent location and remove all packaging.

Check for damage before discarding packaging.

Remove all separately packed accessories such as kits and shelves.

SHIPPING SKID

Each merchandiser is shipped on a skid to protect the merchandiser’s base, and to make positioning the case easier.

Do not remove the shipping skid until the merchandiser is near its final location. The skid provides protection for both the merchandiser and the floor.

Remove the skid by raising one end of the merchandiser approximately 6 inches. Block the merchandiser securely, and remove the two skid bolts from the raised end. Replace the bolts with

(provided) leg levelers. Repeat this procedure at opposing end. Once the leg levelers are secured in place, the merchandiser may be slid off the skid and placed in its final location.

DO NOT TILT MERCHANDISER ON ITS

SIDE OR END WHEN REMOVING SKID.

Do not walk or put heavy objects on case.

Once the skid is removed, the merchandiser must be lifted —NOT PUSHED— to reposition.

Improper handling may cause damage to the merchandiser when unloading. To avoid damage:

Check floor where merchandisers are to be set to see if it is a level area. Determine the highest part of the floor.

1. Do not drag the merchandiser out of the trailer. Use a Johnson bar (mule).

2. Use a forklift or dolly to remove the merchandiser from the trailer.

Do NOT remove shipping crate until the merchandiser is positioned

EXTERIOR LOADING

Do NOT walk on top of merchandisers or damage to the merchandisers and serious personal injury could occur.

MERCHANDISERS ARE NOT STRUCTURALLY

DESIGNED TO SUPPORT EXTERNAL LOADING such as the weight of a person. Do not place heavy objects on the merchandiser.

MERCHANDISER LEVELING

B

E SURE TO POSITION MERCHANDISERS PROPERLY

.

Level the merchandiser by all four corners.

Merchandiser(s) must be installed level to ensure proper operation of the refrigeration system, and to ensure proper drainage of defrost water.

REFRIGERATION UNIT ACCESS

The lower front panel may be removed by removing screw at bottom and lifting the panel straight upward and over the tabs on which it is hanging. The panel is installed by reversing the above procedure.

Ensure lower front panel is flat against the floor when installed to prevent air circulation problems for self contained merchandisers.

OPTIONAL LEGS

NSF ® approved legs replace the leg levelers if required by local health codes. The legs raise the case 6 inches for cleaning purposes. An optional skirt kit can be provided to snap on the legs.

SERIAL PLATE LOCATION

The serial plate is located on the interior top, left side of the merchandiser. It contains all pertinent information such as model, serial number, amperage rating, refrigerant type and charge. This information will be needed to install, service or order parts for the merchandiser.

ELECTRICAL / REFRIGERATION

MERCHANDISER ELECTRICAL DATA ELECTRICAL OUTLET:

Refer to Appendix A of this manual or the merchandiser’s serial plate for electrical information.

FIELD WIRING

Field wiring must be sized for component amperes stamped on the serial plate. Actual ampere draw may be less than specified.

2-1

Before the merchandiser is connected to any wall circuit, use a voltmeter to check that the outlet is at 100% of the rated voltage. The wall circuit must be dedicated for the merchandiser.

Failure to do so voids the warranty. Do not use an extension cord. Never plug in more than one merchandiser per electrical circuit.

• Always use a dedicated circuit with the amperage stated on the unit.

• Plug into an outlet designed for the plug.

• Do not overload the circuit

• Do not use long or thin extension cords.

Never use adapters.

• If in doubt, call an electrician.

ALWAYS CHECK THE SERIAL PLATE FOR

COMPONENT AMPERES

ELECTRICAL CONNECTIONS

All wiring must be in compliance with NEC and local codes. All electrical connections for

GSVM-4072 and 5072 self-contained are to be made in the electrical Handy Box located behind the removable base panel at the left end of the merchandiser when facing the discharge air honeycomb. GSVM-4060 is provided with a power cord.

GSVM-4060 has a factory-installed power cord that is attached at the electrical box.

POWER SWITCH

The main electrical power switch is located behind the front louvered access panel. The power switch must be turned OFF before servicing the merchandiser.

Risk of Electric Shock. If cord or plug becomes damaged, replace only with a cord and plug of the same type.

— LOCK OUT / TAG OUT —

To avoid serious injury or death from electrical shock, always disconnect the electrical power at the main disconnect when servicing or replacing any electrical component. This includes, but is not limited to, such items as doors, lights, fans, heaters, and thermostats.


Merchandiser must be grounded.

Do not remove the power supply cord ground.

NSTALLATION

REFRIGERATION

(Self Contained Models)

Each self contained model is equipped with its own condensing unit and control panel located beneath the display area. The correct type of refrigerant will be stamped on each merchandiser’s serial plate. The merchandiser refrigeration piping is leak tested. The unit is charged with refrigerant, and shipped from the factory with all service valves open.

GSVM models have a refrigeration system that uses a hermetic compressor. GSVM-4060 and GSVM-4072 systems use a capillary tube for refrigerant control. The capillary tube is soldered to the suction line pull-out coil for proper heat exchange. If the capillary should become plugged or damaged, it is best to replace the heat exchanger.

GSVM-5272 employs a bleed port type expansion valve for proper refrigerant control. Read the merchandiser’s serial plate for the appropriate refrigerant type and weight.

WATER OUTLET AND WATER SEAL

GSVM models 4072 and 5272 require a floor drain. The condensate water outlet is located in the center of the merchandiser. The outlet has a factory installed, external water seal.

For self contained models like GSVM-4060, this water seal drains into a high-humidity electric condensate pan located beneath the merchandiser. The pan uses a thermistor that senses water in the pan, adjusting the amount of heat required to evaporate the water. Ensure the drain hose is properly trapped, and the drain area is not clogged.

NOTE: All lower base panels must be in place when the refrigerator is operating. If not, airflow from the condenser will be directed over the evaporator pan and defrost water in the pan may overflow.

OPTIONAL ELECTRIC

CONDENSATE PAN

An optional high-humidity condensate pan kit requires a dedicated 15 Amp circuit - 120V

(GSVM-4072 and GSVM-5272).

TEMPERATURE AND DEFROST

CONTROLLER

SAFE-NET III™ USER INSTRUCTIONS

Your refrigerated case uses a Hussmann

Safe-NET™ III temperature and defrost controller to precisely maintain the temperature and prevent frost buildup on the cooling coil. LEDs indicate when the compressor or refrigeration is on, when the case is in a defrost cycle, if the temperature is outside the desired range, or if there is a sensor failure.

An adjustment knob allows the temperature to be set within the configured range and can power off the controller and compressor. Your controller has been custom-configured to provide the best temperature and defrost control for your chilled or frozen food.

The front of the controller has an adjustment knob and status LEDs. The back of the controller has connections for sensors and switched equipment.

The Safe-NET III controller includes the following features and connections.

• Adjustment knob:

Adjusts the temperature setpoint.

Turn adjustment knob to OFF to turn off refrigeration system. Unplug merchandiser from power before servicing the unit.

• Controller LEDs:

Compressor Powered On LED (green):

Lights while the compressor is running or the refrigeration valve is open.

CLEANING DISCHARGE HONEYCOMB

Discharge air honeycombs should be cleaned every six months. Dirty honeycombs will cause merchandisers to perform poorly.

The honeycombs may be cleaned with a vacuum cleaner. Soap and water may be used if all water is removed from the honeycombs cells before replacing. Be careful not to damage the honeycombs.

1. Using a flat object such as a screw driver, compress the honeycomb and remove it from its retainer.

2. Clean and dry the air honeycombs.

3. After cleaning, replace in reverse order.

Damaged honeycombs must be replaced.

CLEANING STAINLESS STEEL SURFACES

Use non-abrasive cleaning materials, and always polish with grain of the steel. Use warm water or add a mild detergent to the water and apply with a cloth. Always wipe rails dry after wetting.

Use alkaline chlorinated or non-chlorine containing cleaners such as window cleaners and mild detergents. Do not use cleaners containing salts as this may cause pitting and rusting of the stainless steel finish. Do not use bleach.

CLEANING SOLAR THERMOMETER

GSVM models have solar thermometers. The thermometer is located at the top, front center of the merchandiser’s cabinet interior.

To clean the thermometer:

1. Remove the two screws securing the thermometer to its mounting bracket. Remove the sensing element from the clip

2. Use non-abrasive cleaning materials and a mild detergent to clean thermometer.

3. Be sure to wipe the element clean of any residues.

DO NOT FLOOD!

Use only enough water necessary to clean surface. Water must not drip down the case!

Never use ammonia based cleansers, abrasive cleansers, or scouring pads.

Do NOT use HOT water on Cold glass Surfaces.

This can cause the glass to shatter and could result in personal injury. Allow glass fronts, to warm before applying hot water.


P/N 0515275_E 4-3

CLEANING UNDER DISPLAY PAN

Remove all product from the merchandiser and place in cooler. Always disconnect electrical power before cleaning.

1. Remove the display pan

2. Use non-abrasive cleaning materials and a mild detergent to clean display pan.

3. Wipe down the insides of the merchandiser with a mild detergent, and replace display pan. Allow merchandiser to pull down in temperature before loading product.

CLEANING EVAPORATION PAN

(GSVM-4060 S

TANDARD

)

(GSVM-4072/5272-O

PTIONAL

)

The condensate water outlet for self contained models empties into a limited capacity evaporation pan.

Debris or dirt accumulation inside the condensate evaporation pan or on the heater coil will reduce the pan’s evaporation capacity and cause premature heater failure. The evaporation pan waste water will overflow and spill onto the floor if the heater is not properly operating.

Remove accumulated debris from the evaporation pan. Wipe down heater coil with a cloth and warm water. Be sure to remove any dirt, debris or liquids from the heater coil.

Water introduced during cleaning will cause the evaporation pan to overflow.

–

Always Wear gloves and protective eye wear when servicing. Turn off evaporation pan heater, and allow pan to cool.

CLEANING COILS

Condenser coils should be cleaned at least once per month. Additional cleaning may be needed depending on the operational environment. A dirty condenser blocks normal airflow through the coils.

SHUT FANS OFF DURING

CLEANING PROCESS.

REMOVING SCRATCHES FROM BUMPER

Most scratches and dings can be removed using the following procedure.

1. Use steel wool to smooth out the surface area of the bumper.

2. Clean area.

3. Apply vinyl or car wax and polish surface for a smooth glossy finish.

Airflow blockage increases energy consumption and reduces the merchandiser’s ability to maintain operating temperature.

To clean the coils, use a vacuum cleaner with a wand attachment and a soft (non-metallic) brush to remove dirt and debris. Do not bend coil fins. Always wear gloves and protective eye wear when cleaning near sharp coil fins and dust particles.
