INSTALLATION/OPERATION
Initial Setup: If the unit has recently been transported, let it stand still for at least 24 hours before
plugging it in.
Temperature Check: Make sure the unit reaches the desired temperature before loading it with
products.
Ventilation: Ensure proper ventilation around the unit where it will operate.
Accessories: Install all accessories like poly pans, drawers, and casters before plugging in the unit.
Manual Review: Read through this Operation/Owner's Manual in its entirety.
UNBOXING YOUR UNIT
Tools Required:
• Adjustable Wrench
• Phillips Screwdriver
• Level
Procedure:
Remove the outer packaging and inspect for concealed damage. File a claim with the freight carrier
if there is damage.
Move the unit as close to its final location as possible before removing the wooden skid.
Cabinet Location Guidelines
Surface: Install the unit on a strong and level surface to prevent unpleasant noises and
malfunctions.
Indoor Installation: Place the unit in an indoor, well-ventilated area.
Clearance: Maintain a clearance of 3 inches on the back of the unit for optimal performance.
Humidity and Dust: Avoid installation in high-humidity or dusty areas. High humidity can cause the
unit to rust and decrease its efficiency. Dust collected on the condenser coil can cause the unit to
malfunction. Clean the condenser at least once a month with a brush or clean cloth. Malfunctions
due to a dirty condenser will void the warranty.
ELECTRICAL INSTALLATION & SAFETY
Supply Cord: If the supply cord is damaged, it must be replaced by a special cord or assembly
available from the manufacturer or its service agent.
Lamps: Use only identical lamps for replacements.
ELECTRICAL INSTRUCTIONS:
Voltage Check: Before connecting the unit to a power supply, check the incoming voltage with a
voltmeter. If anything less than 100% of the rated voltage for operation is noted, correct it
immediately.
Proper Voltage: All units are equipped with a service cord and must be powered at the proper
operating voltage at all times. Refer to the cabinet data plate for this voltage.
WARNINGS:
• Compressor warranties are void if the compressor burns out due to low voltage.
• The power supply cord ground should not be removed.
• Do not use electrical appliances inside the food storage compartments of the appliances unless
they are of the type recommended by the manufacturer.
Note: To reference the wiring diagram, remove the front louvered grill; the wiring diagram is
positioned on the inside cabinet wall.
SETUP
Standard Accessories: Ensure all standard accessories are properly set up with the unit.
DRAWER REMOVAL & INSTALLATION:
Removal:
1. Open the drawer completely. Roller clips will be in the down position.
2. While holding the sides of the drawer, use your hands to lift the side track of the drawer.
3. Lift the drawer and remove it from the channel.
Installation:
1. Lower rear rollers into channel slots.
2. Make the two side tracks of the drawer horizontal, and lower the front rollers into the channel.
3. Make sure the drawer tracks are in the right position.
STARTUP:
• Plug in the cooler.
• The digital thermostat is factory-set to give refrigerators an approximate temperature of 35°F.
Allow the unit to function for several hours, cooling the cabinet completely before adjusting the
control settings.
• The electronic temperature control is located on the front of the unit.
• Excessive tampering with the control could lead to service difficulties. Should it ever become
necessary to replace the temperature control, consult the manual or a certified technician.
• Note: If the unit is disconnected or shut off, wait five minutes before starting again.
Recommendation:
Before loading products, run your unit empty for two to three days. This ensures that electrical
wiring and installation are correct and that no shipping damage has occurred. Remember, product
loss is not covered by the warranty.
Cleaning the Condenser Coil:
Required Tools:
• Phillips screwdriver
• Stiff bristle brush
• Adjustable wrench
For efficient operation, it's crucial to keep the condenser surface free of dust, dirt, and lint.
Clean the condenser coil and fins at least once per month.
Use a commercial condenser coil cleaner, available from any kitchen equipment retailer. Brush the
condenser fins from top to bottom, not side to side.
After cleaning, straighten any bent condenser fins with a fin comb.
Cleaning the Fan Blade and Motor:
If necessary, clean the fan blades and motor with a soft cloth.
If washing the fan blades, cover the fan motor to prevent moisture damage.
Cleaning the Interior of the Unit:
Use a solution of warm water and mild soap for cleaning the cabinet interior.
Avoid using steel wool, caustic soap, abrasive cleaners, or bleach that may damage the stainless
steel surface.
Door Gaskets:
• Wash door gaskets on a regular basis, preferably weekly.
• Remove the door gasket from the frame of the door, soak in warm water and soap for 30
minutes, dry with a soft cloth, and replace.
• Check door gaskets for a proper seal after they are replaced.
Shelves and Pilasters:
• Periodically remove the shelves and pilasters from the unit and clean them with mild soap and
warm water.
• To remove the pilasters, first remove the shelves and shelf brackets. Then, simply lift the pilaster
up and out.
STAINLESS STEEL CARE AND CLEANING
• For routine cleaning, use soap, ammonia, and mild detergents applied with a soft cloth or
sponge.
• For stubborn stains and discoloration, use non-abrasive cleaners. Rub in the direction of polish
lines.
• For grease and fatty acids, use oven cleaners.
• Any good commercial detergent can be applied with a sponge or soft cloth to remove grease
and oil.
• For restoration and passivation, use appropriate stainless steel cleaners.
CAUTION:
Do not use steel wool, abrasive, or chlorine-based products to clean stainless steel surfaces.
Factors That Can Ruin Stainless Steel:
• Scratches from wire brushes, metal scrapers, and steel pads can break down stainless steel's
passivity layer and allow corrosion to occur.
• Deposits left on stainless steel can leave spots and break down the passivity layer.
• Chlorides present in table salt, food, and water can also break down the passivity layer.
8 Steps to Prevent Rust on Stainless Steel:
1. Use non-abrasive tools for cleaning.
2. Clean along the polish lines.
3. Use alkaline, alkaline chlorinated, or non-chloride containing cleaners.
4. Use soft water for cleaning to reduce deposits.
5. Maintain cleanliness of food equipment.
6. Rinse and wipe dry immediately when using chlorinated cleaners.
7. Never use hydrochloric acid (muriatic acid) on stainless steel.
8. Regularly restore or passivate stainless steel.
