INDOOR UNIT INSTALLATION STEP 1: SELECT INSTALLATION LOCATION Before installing the indoor unit, you must choose an appropriate location. The following standards should be met for an appropriate location for the unit: • • • • • • Good air circulation Convenient drainage Noise from the unit will not disturb other people Firm and solid - the location will not vibrate Strong enough to support the weight of the unit A location at least three feet (one meter) from all other electrical devices (e.g.
STEP 2: MOUNT INDOOR UNIT Depending on the model, fix the mounting plate or brackets to the wall with tapping screws and mount the unit. The bottom of the unit can touch the floor or remain suspended, but the body must be installed vertically. Refer to the diagrams below.
STEP 3: DRILL WALL HOLE FOR CONNECTIVE PIPING 1. Determine the location of the wall hole based on the location of the outdoor unit. 2. Using a 2 1/2" (65mm) core drill for units with a gas side connective pipe less than 5/8" (16mm), or 3 1/2" (90mm) for units with a gas side pipe greater than or equal to 5/8" (16mm), drill a hole in the wall. Make sure that the hole is drilled at a slight downward angle, so that the outdoor end of the hole is lower than the indoor end by about 3/16 - 1/4" (5mm to 7mm).
STEP 5: CONNECT DRAIN PIPE The drain pipe is used to drain condensate water away from the unit. Improper installation may cause leaks and unit or property damage. 1. Connect the drain pipe (field supplied) to the unit's connecting port using a metal worm clamp. Make sure it secured tightly and can not be easily pulled loose. 2. Insulate the connecting port and pipe with the accessory sheath (sleeve) provided.
7. Only connect the unit to an individual branch circuit outlet. Do not connect another appliance to that outlet. 8. Make sure to properly ground the air conditioner. 9. Every wire must be firmly connected. Loose wiring can cause the terminal to overheat, resulting in product malfunction and possible fire. 10. Do not let wires touch or rest against refrigerant tubing, the compressor, or any moving parts within the unit. 11.
