5. GENERAL INFORMATIONS

1. CHANGING AIR FLOW DIRECTION

Air flow deflectors divert air from center flow to left or right and up or down.
Adjust deflectors for desired air flow pattern.

2. AIR FLOW AROUND UNIT

Check in door grill and outdoor louvers for air flow obstructions. Do not block air flow to and from unit. The outdoor coil
should be checked and periodically cleaned for debris that may collect and block unit air flow. If air flow is obstructed
or deflected back into unit, the compressor may cycle on and off rapidly, causing early compressor failure.

3. Electrical Grounding Instructions.

This appliance is equipped with a three-prong(grounding) plug for protection against possible shock hazards. If a two-
prong wall receptacle is encountered, the customer is required to contact a qualified electrician and have the two-
prong wall receptacle replaced with a properly grounded three-prong wall receptacle in accordance with the National
Electrical Code.

4. USE OF EXTENSION CORDS

Because of potential safety hazards under certain conditions we strongly recommend against the use of an extension
cord. However, if you still elect to use an extension cord, it is absolutely necessary that it be a UL listed 3-wire
grounding type appliance extension cord rated has a 3-blade grounding plug and a 3-slot receptacle that will plug into
appliance. 

5. DRAIN HOLE AND WATER DRIPPING OUTSIDE

Locate drain hole at the rear of unit. Water in base pan is picked up by the fan blade and thrown onto the warm
outdoor coil where it evaporates. The air conditioner must be installed level or tited or slightly to the outside for proper
water disposal. On exceptionally hot and humid days the air conditioner may permit excess water to pass thru rear
drain hole or overflow. This should be considered normal.
