Testing of drain piping
After the 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 single-phase
power supply (50 Hz, 230 V) to connections No. 1 and
No. 2 on the inter unit wiring terminal block and connect
the ground wire firmly (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 power, remove
the control box lid and disconnect the single phase power
supply from the inter unit wiring terminal block again.
Attach the control box lid as before.

General instructions
■
All field wiring and components must be installed by a licensed
electrician and must comply with relevant European and national
regulations.
■
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.
■
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.
■
Refer to the installation manual attached to the outdoor unit for
the size of power supply electric wire connected to the outdoor
unit, the capacity of the earth leakage circuit breaker and fuse,
and wiring instructions.
■
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.
