MODEL DESCRIPTION

The ISFGG and ISMGG models are island, spot display merchandisers. They are available as either remote type, which require a separate condensing unit connection, or self contained. Each self contained model will have its own condensing unit, factory installed beneath the display area of the case ready for operation when electrical service is connected.

ISFGG models are designed for low temperature and dual-temperature operation: either low temperature (frozen food), or medium temperature (fresh meat, dairy and delicatessen models). ISMGG model is designed for medium temperature operation.

ISFGG and ISMGG have upper glass on all four sides of the merchandiser.

Do not walk or put heavy objects on case.

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.

SHIPPING SKID

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

Remove the top of the crate and detach walls from each other. Lift crate from the skid.

Unscrew the case from the skid. The fixture can now be lifted off the crate skid. Lift only at

base of skid! Remove any braces and/or skids attached (blanket wrapped merchandiser may have skids).

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.

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

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 LAY MERCHANDISER OVER

ON THE FLOOR TO REMOVE SKID.

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

To remove the skid, remove screws attaching skid to the merchandiser.

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

Do NOT remove shipping crate until the merchandiser is positioned

SEALING MERCHANDISER TO FLOOR

i

SERIAL PLATE LOCATION

The serial plate is located on the inside of the merchandiser’s display area.

If required by local sanitary codes, or if the customer desires, merchandisers may be sealed to the floor using a vinyl cove base trim. The size needed will depend on how much variation there is in the floor, from one end of the merchandiser to the other. Sealing of the lower front and rear panels on self contained models may hamper their removal for servicing or maintenance of the condensing unit.

REFRIGERATION UNIT ACCESS

NOTE: Do not allow trim to cover any intake or discharge grilles located in the lower front panel.

The lower front panel may be removed by lifting the panel straight upward and over the tabs on which it is hanging. In a self contained merchandiser, two screws will have to be removed from either end of the panel. 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.

ELECTRICAL / REFRIGERATION

MERCHANDISER ELECTRICAL DATA

2-1

Refer to the technical data sheets and merchandiser 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.

ALWAYS CHECK THE SERIAL PLATE FOR

COMPONENT AMPERES

— 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.

ELECTRICAL CONNECTIONS

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

remote models) 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 louver.

Self-contained models have factory-installed power cords attached at the electrical box.

ELECTRICAL OUTLET:

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.

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.

• 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.

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


Merchandiser must be grounded.

Do not remove the power supply cord ground.

LECTRICAL

REFRIGERATION

(Remote Models)

/ R

EFRIGERATION

Refrigeration temperature is controlled by an electronic factory-installed thermostat. The electronic thermostat controls a liquid line solenoid valve (not provided with the merchandiser). The thermostat energizes the valve as the temperature rises. A pump down system is recommended for outdoor condensing units.

LINE SIZING

(Remote Models)

Refrigerant line connections are made at the right end of merchandiser (facing front) beneath the refrigerated display area. The refrigerant line connection size is

3

/

8 in. The suction line is

5

/

8 in. Refrigerant lines should be sized as shown on the refrigeration legend that is furnished for the store or according to

ASHRAE guidelines.

KOOLGAS

(Remote Models)

If Koolgas defrost is used, the liquid line will need to be increased two sizes larger inside the merchandiser area. This is necessary to ensure even liquid drainage from all evaporators during defrost.

Refrigerators with Koolgas defrost

SHOULD

NOT

have their liquid lines and suction lines in contact with each other but are to be separately insulated for a minimum of 30 ft from the refrigerator. Additional information for the balance of the refrigerant lines is recommended and required wherever condensation and dripping would be objectionable.

Oil Traps

P-traps (oil traps) must be installed at the base of all suction line vertical risers.

Pressure Drop

Keep refrigerant line runs as short as possible to avoid large pressure drops. Use a minimum number of elbows. Where elbows are required,

USE LONG RADIUS ELBOWS ONLY

.

Refrigeration lines are under pressure.

Refrigerant must be recovered before attempting any connection or repair.

For refrigerators with other than Koolgas defrost, the suction and liquid line should be clamped and/or taped together and insulated for a minimum of 30 feet from the refrigerator.

When brazing pipes, be sure to use the insulation blanket shipped with the merchandiser to prevent damage to the metal merchandiser bottom.

P/N 0515154_C


P/N 0515154_C

COMPRESSOR

(Self Contained)

The ISF compressor is mounted on vibration springs. The compressor is banded down during shipment. This band MUST be cut and removed

to allow the compressor to float freely once

placed into operation. Failure to cut compressor shipment band may result in excessive noise or system damage.

WATER OUTLET AND WATER SEAL

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, this water seal drains into the condensate evaporator pan located beneath the merchandiser.

For remote models, this water seal consists of a moulded trap that requires drip piping to connect with a floor drain. The merchandiser is equipped with a 1

1

/

2 in. female National Pipe

Thread (NPT) for field installation.

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.

Product will be degraded and may spoil if allowed to sit in a non-refrigerated area.

Safe-NET III™

TEMPERATURE AND DEFROST CONTROLLER

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.

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.

• Controller LEDs:

Compressor Powered On LED (green):

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

Defrost Cycle LED (yellow):

Lights while the refrigeration coil is defrosting.

Temperature or Sensor Alarm (red):

Lights if the temperature is too warm or too cold. Flashes if a sensor fails.

PERATION

START UP

Follow the Safe-NET III start up procedures as detailed in Section 3 of this manual.

Each self contained merchandiser has its own evaporator coil and a pre-set thermostatic expansion valve (TEV). The TEV has been factory set at design conditions to provide the recommended performance.

The crankcase pressure regulating (CPR) refrigeration valve is factory set and requires no adjustment.

TEV Adjustment

Expansion valves may be adjusted to fully feed the evaporator. Before attempting to adjust valves, make sure the evaporator is clear or only lightly covered with frost, and the merchandiser is within 10°F of its expected operating temperature.

Adjust the valve as Follows: a. Attach a probe to the suction line near the expansion valve bulb.

b. Obtain a pressure reading from the factory installed Schraeder valve. Convert the pressure reading to a saturated temperature for the refrigerant.

Temperature (b) minus Temperature (a) is the superheat. The valve should be adjusted so that the greatest difference between the two temperatures is 3°F to 5° F.

Make adjustments of no more than

1

/

2 turn of the valve stem at a time and wait for at least 15 minutes before rechecking the probe temperature and making further adjustments.

MAINTENANCE

CARE AND CLEANING

Long life and satisfactory performance of any equipment is dependent upon the care it receives. To ensure long life, proper sanitation and minimum maintenance costs, these merchandisers should be thoroughly cleaned, all debris removed and the interiors washed down, weekly.

Do:

•Remove the product and all loose debris to avoid clogging the waste outlet.

•Store product in a refrigerated area such as a cooler. Remove only as much product as can be taken to the cooler in a timely manner.

Exterior Surfaces

The exterior surfaces must be cleaned with a mild detergent and warm water to protect and maintain their attractive finish. N

EVER USE

ABRASIVE CLEANSERS OR SCOURING PADS

.

Interior Surfaces

The interior surfaces may be cleaned with most domestic detergents, ammonia based cleaners and sanitizing solutions with no harm to the surface. Self contained models empty into a limited capacity evaporation pan, which will overflow if excess water is used in cleaning.

•Disconnect electrical power before cleaning.

•Thoroughly clean all surfaces with soap and hot water. D

.

•Take care to minimize direct contact between fan motors and cleaning or rinse water.

Do NOT Use:

•Abrasive cleansers and scouring pads, as these will mar the finish.

Do NOT allow cleaning agent or cloth to contact food product.

•Coarse paper towels on coated glass.

•Ammonia-based cleaners on acrylic parts.

•Solvent, oil or acidic based cleaners on any interior surfaces.

•Do NOT flood merchandiser with water.

N

EVER INTRODUCE WATER FASTER THAN THE

WASTE OUTLET CAN REMOVE IT

.

•Do not use high pressure water hoses.

SELF CONTAINED MODELS EMPTY INTO AN

EVAPORATION PAN THAT WILL OVERFLOW IF TOO

MUCH WATER IS INTRODUCED DURING CLEANING

.

•Allow merchandisers to dry before resuming operation.



•After cleaning is completed, turn on power to the merchandiser.


4-2

M

AINTENANCE

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.

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.

CLEANING DISCHARGE AIR LOUVERS

CLEANING UNDER FAN PLENUM

To facilitate cleaning, the fan plenum is hinged.

After cleaning be sure the plenum is properly lowered into position

OR PRODUCT LOSS WILL

RESULT due to improper refrigeration.

Discharge air louvers should be cleaned every six months. Dirty louvers will cause merchandisers to perform poorly. The louvers may be cleaned with a vacuum cleaner.

Soap and water may be used if all water is removed from the louvers cells before replacing.

Be careful not to damage the louvers.



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 louvers.

3. After cleaning, replace in reverse order.

Damaged louvers must be replaced.

P/N 0515154_C


P/N 0515154_C

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.

4-3

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.

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.

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.



4-4

M

AINTENANCE

CLEANING EVAPORATION PAN

(SELF CONTAINED ONLY)

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.

Evaporation Pan is Hot!

and poses risk of bodily injury

–

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

When Cleaning:

PRECAUTION

CLEANING PRECAUTIONS

UNIT WITH AN EVAPORATION PAN

THAT HAS OIL BASE (these will dissolve the butyl

sealants) or an AMMONIA BASE (this will corrode the

copper components of the merchandiser)

(these will mar the finish)

T

HE BLADES MUST BE INSTALLED WITH RAISED

EMBOSSING

(

PART NUMBER ON PLASTIC BLADES

)

POSITIONED AS INDICATED ON THE PARTS LIST

.

For access to these fans:

1. Remove product and place in a refrigerated area. Turn off power to the merchandiser.

2. Remove bottom display pans.

3. Disconnect fan from wiring harness.

4. Remove fan blade.

5. Lift fan plenum and remove screws holding bottom of motor to fan basket.

6. Replace fan motor and blade.

7. Lower fan plenum.

8. Reconnect fan to wiring harness.

9. Turn on power.

10. Verify that motor is working and blade is turning in the correct direction.



11. Close air gaps under fan plenum. Warmer air moving into refrigerated air reduces effective cooling. If the plenum does not rest against the case bottom without gaps, apply foam tape to the bottom of the fan plenum to reduce improper air movement.

Use silicone sealant to close other gaps.

12. Reinstall display pans. Bring merchandiser to operating temperature before restocking.
