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. Check them and make
sure that they are all tightly fastened. (If they are loose, it could cause burn-out of the wires.)

4. Checking the Drainage and Forming the Pipings
1) Checking the drainage
1. To remove the front panel from the indoor unit.
• Set the air direction louvers up-and-down to the posi-
tion(horizontally) by hand.
• Remove the securing screws that retain the front pan-
el. Pull the lower left and right sides of the grille
toward you and lift it off.

3. Drain piping
• The drain hose should point downward for easy drain
flow.
• Do not make drain piping.
2) Form the piping
1. Form the piping by wrapping the connecting por-
tion of the indoor unit with insulation material and
secure it with two kinds of vinyl tapes.

• If you want to connect an additional drain hose, the
end of the drain outlet should be routed above the
ground. Secure the drain hose appropriately.

2. In cases where the outdoor unit is installed below
the indoor unit perform the following.
• Tape the piping, drain hose and connecting cable from
down to up.
• Secure the tapped piping along the exterior wall using
saddle or equivalent.
