INSTALLATION
1. GOOD AIR CIRCULATION
- Be sure to avoid any object which will restrict exhausted air flow.
- Be sure that there is ample space so that air can flow through the rear of the unit.
- The back of the unit should be located 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 SOURCE
- Be sure to avoid hot corner or location near stove, oven, or other heat source.
- High ambient temperature will make cooling efficiency lower.
4. INDOOR USAGE ONLY
- This equipment is intended for indoor use only.
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 electrical circuit.
- Do not use extension cords
- Isolate the unit on an electrical circuit of proper size.
8. Place black plastic condensate pan thru back or front.
Make sure pads are installed upwards and drain hose is in pan.
9. Install the unit where the air circulation is good.
- Maintain enough spaces around the unit since air
circulation is very important for the unit cooling
performance.
- If air circulation is obstructed, then cooling
performance will drop, consuming more electricity as
a result.
ᵀReference
⍥If a door for left hand is necessary, please contact the sales
representative in your area.
⍥A set of door & Door hinge can be purchased separately to
convertible between Right Hand and Left Hand side.
