■ Precautions
- Install the drain raising pipes at a height of less than 625 mm.
- Install the drain raising pipes at a right angle to the indoor
unit and no more than 300 mm from the unit.
-To prevent air bubbles, install the drain hose level or slightly
tilted up (≤75 mm).
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. Check for water leaks.
Method of adding water. See figure 7.
First perform electric wiring work as instructed in "Electric wiring
work" on page 5 and how to set the remote controller as explained in
"Wiring example and how to set the remote controller" on page 6.
When electric wiring work is finished
Check drainage flow during COOL running, explained in "Test
operation" on page 8.
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 5 for switch box
attachment/detachment) (Refer to figure 11 and 12)
■ 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 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.
■ 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 electrical wires are stripped
equally.
NOTE
The incline of attached drain hose should be
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
hanging bars every 1 to 1.5 m.
When unifying multiple drain pipes, install the
pipes as shown in figure 10. Select converging
drain pipes whose gauge is suitable for the
operating capacity of the unit.
1 T-joint converging drain pipes
1 Water inlet
2 Portable pump
3 Water inlet cover
4 Bucket (adding water through water inlet)
5 Drain outlet for maintenance (with rubber drain plug)
6 Refrigerant pipes
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
