NOTICE TO CUSTOMER
INSTALLATION
Loss or spoilage of products in your refrigerator/freezer is not covered by warranty.
In addition to following recommended installation procedures, you must run the
refrigerator/freezer 24 hours prior to usage.
1. LOCATION - Allow adequate space and install the refrigerator on a firm and level floor.
If the appliance is not level, there may be unusual noises and poor cooling performance.
2. GOOD AIR CIRCULATION - Be sure to avoid any partition and object which may
stop the air flow and that air space is allowed to flow to the rear and/or sides of the unit
between the refrigerator and the back wall. Insufficient space causes vibration noise,
inefficient refrigeration, damage to the refrigeration system, and the waste of
electricity (Turbo Air recommends that the rear of the unit should be no less than
5 inches from the wall).
3. PLACE ON STRONG FLOOR - Be sure that the floor on which the unit is to be installed
is strong enough to support the total weight of the cabinet and any other contents,
before starting the installation.
4. DO NOT PLACE NEAR HEAT - Be sure to avoid hot corners and other locations such
as near stoves. High ambient temperature will result in much lower cooling efficiency.
5. INDOOR USAGE ONLY - Be sure to install this unit indoors only, to prevent getting wet
from the rain. Do not install the refrigerator in locations where the temperature is over
100°F (43°C) or below 50°F (10°C).
6. STABILIZING- Make sure the unit is installed in a stable condition with the front wheels
locked while in use.
7. LEVELING- Be sure that the unit levels from the front to the back and side to side.
8. UNIT SHOULD BE ON DEDICATED OUTLET - Plug the refrigerator into a wall socket
exclusively for this appliance. Do not run on extension cord.
9. THE ELECTRICAL PLUG MUST BE ACCESSIBLE WITHOUT MOVING THE UNIT.
10. WHEN POSITIONING FOOD FOR STORAGE, A MAXIMUM OF ONE SHELF MAY
BE LOADED LESS THAN 110lb (50kg), BUT DO NOT ALLOW LOADS TO OVER
HANG FROM THE FRONT AND REAR EDGES OF SHELVES.
