Testing of drain piping
After piping work is finished, check if drainage flows smoothly.
■
Add approximately 1 l of water gradually through the air
discharge outlet.
Method of adding water. See
figure 11 .
■
Check the drainage flow.
■
In case electric wiring work is finished
Check drainage flow during COOL running, explained in "Test
operation" on page 9 .
■
In case electric wiring work is not finished
- Remove the control box lid. Connect the power supply
firmly to the terminal. See
figure 10 .
- Reattach the control box lid 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 the power,
remove the control box lid and disconnect the power
supply from the terminal again.
- Reattach the control box lid.

LECTRIC WIRING WORK
General instructions
■
All field supplied parts and materials and electric works must
conform to local codes.
■
Use copper wire only.
■
Follow the "Wiring diagram" attached to the unit body to wire the
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.
■
Attach the earth leakage circuit breaker and fuse to the power
supply line.
■
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 legislation.
Note that the operation will restart automatically if the main
power supply is turned off and then turned back on again.
■
This system consists of multiple indoor units. Mark each indoor
unit as unit A, unit B..., and be sure the terminal block wiring to
the outdoor unit is matching properly. If wiring and piping
between the outdoor unit and an indoor unit are mismatched,
the system may cause a malfunction.
■
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.
