NOTE
The incline of attached drain hose should be
3 in. (75 mm) or less so that the drain socket does
not have to withstand additional force.
To ensure a downward slope of 1:100, install
suspension bolts every 40 in. (1 m) to 60 in.
(1.5 m).
When unifying multiple drain pipes, install the
pipes as shown in figure 8. Select converging
drain pipes whose gauge is suitable for the
operating capacity of the units.

Testing of drain piping
After the piping work is finished, check if drainage flows smoothly.
Add approximately 0.25 gal (1
) of water gradually through the air
discharge outlet.
Method of adding water (See figure 10)

Check the drainage flow.
In case electric wiring work is finished
Check drainage flow during cooling operation, explained in
“Test operation” on page 10.
In case electric wiring work is not finished
-
Remove the control box cover by means of two screws.
Connect the single-phase power supply (208/230V 60Hz) to
terminals L1 and L2 on the terminal block for power supply and
connect the ground wire firmly (See figure 9).
-
Reattach the control box cover and turn on the power.
- Do not touch the drain pump. It may result in electric shock.

-
Confirm the drain operation looking at the drain socket.
-
After checking the drainage flow, turn off power, remove the
control box cover and disconnect the power supply wiring from
the terminal block for power supply again. Attach the control
box cover as before.
Electric wiring work
General instructions
All field wiring and components must be installed by a licensed
electrician and must comply with relevant national, state and local code.
Use copper wire only.
Follow the ‘Wiring diagram label’ attached to the back side of the
control box cover to wire outdoor unit, indoor units and the remote
controller. For details on hooking up the remote controller, refer to
the installation manual of the remote controller.
All wiring must be performed by an authorized electrician.
A main switch or other means for disconnection, having a contact
separation in all poles, must be incorporated in the fixed wiring in
accordance with relevant local and national code.
Note that the operation will restart automatically if the main power
supply is turned off and then turned back on again.
Be sure to ground the air conditioner.
Do not connect the ground wire to:
-
gas pipes: might cause explosions or fire if gas leaks.
- telephone ground wires or lightning rods: might cause abnormally
high electric potential in the ground during lightning storms.
- plumbing pipes: no grounding effect if hard vinyl piping is used.
