First perform electric wiring work as instructed in
"Electric wiring
work" on page 6
and how to set the remote controller as explained in
"Wiring example and how to set the remote controller" on page 7
.
When electric wiring work is finished
Check drainage flow during COOL running, explained in
"Test
operation" on page 9
.
When electric wiring work is not finished
Remove the switch box cover and connect the single-phase
power supply and the remote controller to the terminals. (Refer
to chapter
"Electric wiring work" on page 6
for switch box
attachment/detachment) (Refer to
figure 12
and
13
)
Connect the single-phase power supply to connections 1 and 2
(as shown in the figure) on the power supply terminal board and
confirm drain operation.
Be aware that the fan will turn during the operation.
After confirming drainage, turn off the power.
Electric wiring work
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.
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.
Refer to the installation manual delivered with the outdoor unit
for the size of power supply electric wire connected to the
outdoor unit, the capacity of the earth leakage breaker and fuse
and for 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.
Make sure that earth wire between the pull relief
and terminal is longer than other wires.
Be sure that the shape of the power supply
cable and any other cable, before entering unit,
should be as shown in this figure.
All cables entering the unit should be fixed by
tie wraps (accessory).
Use long sealing (accesory) to block entrance
of switch box as shown in
figure 12
.
Caution for drain socket
Do not remove the drain pipe plug. Water might leak out.
The drain outlet is only used to discharge water if the drain
pump is not used or before maintenance. Gently put in and
out the drain plug. Excessive force may deform the drain
socket of the drain pan.
Pulling out the plug
Do not wiggle the plug up and down
Pushing in the plug
Set the plug and push it by using a crosshead screw-
driver
