Connect the indoor unit first then the outdoor unit. Bend andarrange the pipecarefully. Insulate bothof the auxiliarypiping. Drainage cannot annoy yourneighbor.

Caution

4. Electrical Work

Prepare the power source for exclusive with the air conditioner. The supply voltage must be the same as the rated voltage of the air conditioner.

NOTE:

A disconnectiondevice having anair gap contactseparation at least 3mm in all conductors should be incorporated in the fixed wiring according tothe National WiringRegulation.

Caution

Perform thewiring with sufficientcapacity. Installation places legally require a short circuit isolator to be attached toprevent electrical shock. Do notextend the powercable code by cutting. The plug of the air conditioner takes a grounding leg, so clients should use a grounding socket so thatthe air conditioner can be grounded efficiently.

5. Connecting Cables

Inside the room

The outdoor unit shouldnot be exposed to strongwind. Fix the outdoor unit with

10 anchor

bolts.

Pass the piping through the hole inthe wall. Put the upper claw at the back of the indoor unit on the upper hook of the installation plate, Move the indoor unit from side to side to see that it is securely hooked. Push the lower part of the indoor unitup on the wall. Piping can easily be made by lifting the indoor unit with a cushioning material at the remote controller holder side between theindoor unit andthe wall.
