INSTALLATION
1. GOOD AIR CIRCULATION
- Be sure to avoid any object which may stop the air flow.
- Be sure that there is ample air space so that air can flow through the rear of the unit.
- Turbo Air recommends that the rear of the unit be no less than 5 inches from the wall.
2. PLACE ON STRONG GROUND
- Be sure the location chosen has a floor strong enough to support the total weight of
the cabinet and contents.
3. DO NOT PLACE NEAR HEAT
- Be sure to avoid hot corners and locations near stoves.
- High ambient temperature will make much lower cooling efficiency.
4. INDOOR USAGE ONLY
- Be sure to install this unit indoor, so it will not get wet from the rain.
5. STABILIZING
- Make sure the unit is installed in a stable condition with the front wheels locked
while in use.
6. LEVELING
- Be sure that the unit is level from front to back and side to side.
7. UNIT SHOULD BE ON DEDICATED OUTLET.
6
CLEANING
Before cleaning, turn unit off at power switch.
1. CLEANING THE INTERIOR AND EXTERIOR
- The interior and exterior of the unit can be cleaned using warm water with soap.
- Do not use an abrasive cleaner because it will scratch the surface.
2. COMPRESSOR AND CONDENSER
- Be sure to keep the condenser coil must be free of dust because of cooling
effect higher.
3. CLEAN THE GASKET
- The door gasket should be cleaned frequently to maintain proper sealing.
4. CHECK AFTER CLEANING
- Plug unit back in and turn on power switch.
- Check that the unit is operating properly.
CAUTION
1. POWER CORD
- Be sure the power cord is connected to the proper voltage.
- A protected circuit of the correct voltage and amperage must be run for connection
of the line cord.
- Turn ʻoffʼ the power switch before disconnecting the power cord, whenever
performing maintenance functions or cleaning the refrigerated cabinet.
- Compressor warranties are void if compressor burns out due to low voltage.
2. RE-STARTING
- If disconnected, wait 5 minutes before re-starting.

BASIC OPERATION
REFRIGERATORS
1. The controller(thermostat) is located at the right inside of the unit.
2. The factory setting for the control is ‘Normal’
3. Set toward ‘Cool’ for higher temperature and ‘Cold’ for lower temperature.
4. The thermostat controls compressor’s on/off by sensing inside temperature.
• If thermostat knob is pointing at OFF, compressor and condenser fan motor
would not run.
• Keep unit unplugged, if not in use for a long period of time.

STAINLESS STEEL EQUIPMENT CARE AND CLEANING
CAUTION : Do not use any steel wool, abrasive or chlorine based products to
clean stainless steel surfaces.
Stainless Steel Opponents
There are three basic things which can break down your stainless steel’s passivity layer and allow
corrosion to rear its ugly head.
1) Scratches from wire brushes, scrapers, and steel pads are just a few examples of items that
can be abrasive to stainless steel’s surface.
2) Deposits left on your stainless steel can leave spots. You may have hard or soft water depending on what part of the country you live in. Hard water can leave spots. Hard water that is
heated can leave deposits if left to sit too long. These deposits can cause the passive layer to
break down and rust your stainless steel. All deposits left from food prep or service should be
removed as soon as possible.
3) Chlorides are present in table salt, food, and water. Household and industrial cleaners are the
worst type of chlorides to use.
8 step that can help prevent rust on stainless steel:
1. Using the correct cleaning tools
Use non-abrasive tools when cleaning your stainless steel products. The stainless steel’s
passive layer will not be harmed by soft cloths and plastic scouring pads. Step 2 tells you how
to find the polishing marks.
2. Cleaning along the polish lines
Polishing lines or “grain” are visible on some stainless steels. Always scrub parallel to visible
lines on some stainless steels. Use a plastic scouring pad or soft cloth when you cannot see
the grain.
3. Use alkaline, alkaline chlorinated or non-chloride containing cleaners
While many traditional cleaners are loaded with chlorides, the industry is providing an ever
increasing choice of non-chloride cleaners. If you are not sure of your cleaners chloride content
contact your cleaner supplier. If they tell you that your present cleaner contains chlorides, ask if
they have an alternative. Avoid cleaners containing quaternary salts as they can attack
stainless steel, causing pitting and rusting.
14
4. Water Treatment
To reduce deposits, soften the hard water when possible. Installation of certain filters can
remove corrosive and distasteful elements. Salts in a properly maintained water softener can
be to your advantage. Contact a treatment specialist if you are not sure of the proper water
treatment.
5. Maintaining the cleanliness of your food equipment
Use cleaners at recommended strength (alkaline, alkaline chlorinated or non-chloride). Avoid
build-up of hard stains by cleaning frequently. When boiling water with your stainless steel
equipment, the single most likely cause of damage is chlorides in the water. Heating nay
cleaners containing chlorides will have the same damaging effects.
6. Rinse
When using chlorinated cleaners you must rinse and wipe dry immediately. It is better to wipe
standing cleaning agents and water as soon as possible. Allow the stainless steel equipment to
air dry. Oxygen helps maintain the passivity film on stainless steel.
7. Hydrochloric acid (muriatic acid) should never be used on stainless steel.
8. Regularly restore/passivate stainless steel.
Recommended cleaners for certain situation/environments of stainless steel.
A) Soap, ammonia and detergent medallion applied with a cloth or sponge can be used for
routine cleaning.
B) Arcal 20, Lac-O-Nu Ecoshine applied provides barrier film for fingerprints and smears.
C) Cameo, Talc, Zud First Impression is applied by rubbing in the direction of the polished lines
for stubborn stains and discoloring.
D) Easy-off and De-Grease it oven aid are excellent for removals on all finishes for grease-fatty
acids, blood and burnt-on foods.
E) Any good commercial detergent can be applied with a sponge or cloth to remove grease and
oil.
F) Benefit, Super Sheen, Sheila Shine are good for restoration/passivation.
