OUTDOOR UNIT INSTALLATION Caution Strong wind Keep this unit away from direct radiation of the sun or other heaters. If unavoidable, please cover it with a shelter. In places near coast or with a high attitude where the wind is strong, please install the outdoor unit against the wall to ensure normal performance. Use a baffle when necessary. In the case of extremely strong wind, please prevent the air from flowing backwards into the outdoor unit.
>60cm Please fasten the feet of this unit with bolts firmly to prevent it from collapsing in case of earthquake or strong wind. Make concrete foundation. (Refer to chart 14) Obstacle Fix with bolt Deep foundation Necessary width Chart 14 INSTALL THE CONNECTING PIPE Check whether the height drop between the indoor unit and outdoor unit, the length of refrigerant pipe, and the number of the bends meet the following requirements: The max height drop.......................................................
Cautions Daub the surfaces of the flare pipe and the joint nuts with frozen oil, and wrench it for 3~4 rounds with hands before fasten the flare nuts. (Refer to chart 14) Be sure to use two wrenches simultaneously when you connect or disconnect the pipes. 2) The stop valve of the outdoor unit should be closed absolutely (as original state). Every time you connect it, first loosen the nuts at the part of stop valve, then connect the flare pipe immediately (in 5 minutes).
CONNECT THE DRAIN PIPE 1. Install indoor unit drain pipe The outlet has PTI screw bread, Please use sealing materials and pipe sheath (fitting) when connecting PVC pipes. CAUTIONS The drain pipe of indoor unit must be heat insulated, or it will condense dew, as well as the connections of the indoor unit. Hard PVC binder must be used for pipe connection, and make sure there is no leakage. With the connection part to the indoor unit, please be noted not to impose pressure on the side of indoor unit pipes.
WIRING Attaching wiring 1. The air conditioner should use separate power supply with rated voltage 2. The external power supply to the air conditioner should have ground wiring, which is linked to the ground wiring of the indoor and outdoor unit. 3. The wiring work should be done by qualified persons according to circuit drawing. 4. A leakage protector should be installed according to the National Standard concerning electrical appliance. 5.
