INSTALLATION INSTRUCTIONS Hang the ind oor u nit on the ho ok. (The b ottom of bo dy can touch with floor or sus pende d, but the b ody must install vertica lly. ) CAUTION Keep indoor unit, outdoor unit, power supply wiring and transmission wiring at least 1 meter away from televisions and radios. This is to prevent image interference and noise in those electrical appliances. (Noise may be generated depending on the conditions under which the electric wave is generated, even if 1 meter is kept.) Fig.

INSTALLATION INSTRUCTIONS When the declivity of the drain pipe downwards is over 1/100, there should not be any winding. The total length of the drain pipe when pulled out traversely shall not exceed 20m, when the pipe is over long, a prop stand must be installed to prevent winding. Refer to the figures on the right for the installation of the pipes. Be sure to locate the power wiring and the signal wring well to avoid cross-disturbance.
INSTALLATION INSTRUCTIONS Outdoor unit installation Outdoor installation precaution Install the outdoor unit on a rigid base to prevent increasing noise level and vibration. Determine the air outlet direction where the discharged air is not blocked. In the case that the installation place is exposed to strong wind such as a seaside, make sure the fan operating properly by putting the unit lengthwise along the wall or using a dust or shield plates.
REFRIGERANT PIPE CONNECTION Drain joint installation NOTE: The drain joint differ from appliance to appliance. Fit the seal into the drain joint, then insert the drain joint into the base pan hole of outdoor unit, 。 rotate 90 to securely assemble them. Connecting the drain joint with an extension drain hose (Locally purchased), in case of the water draining off the outdoor unit during the heating mode.

AIR PURGING After the confirmation of the above conditions, prepare the wiring as follows: 1) Never fail to have an individual power circuit specifically for the air conditioner. As for the method of wiring, be guided by the circuit diagram posted on the inside of control cover. 2) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation.
AIR PURGING When relocate the unit to another place, perform evacuation using vacuum pump. Make sure the refrigerant added into the air conditioner is liquid form in any case. (Not applicable to the units adopt freon R22 ) Refrigerant Outdoor unit Indoor unit A Gas side C Liquid side D Caution in h andli ng th e packed valve Open the valve stem until it hits against the stopper. Do not try to open it further. Securely tighten the valve stem cap with a spanner or the like.
AIR PURGING Safety and leakage check ● Elec trical safet y check Perform the electric safe check after completing installation: 1. Insulated resistance The insulated resistance must be more than 2MΩ. 2. Grounding work After finishing grounding work, measure the grounding resistance by visual detection and grounding resistance tester. Make sure the grounding resistance is less than 4Ω . 3.
TEST RUNNING Test running Perform test operation after completing gas leak check at the flare nut connections and electrical safety check. Check that all tubing and wiring have been properly connected. Check that the gas and liquid side service valves are fully open. 1. Connect the power, press the ON/OFF button on the remote controller to turn the unit on. 2. Use the MODE button to select COOL, HEAT, AUTO and FAN to check if all the functions works well. 3.
