Pump down operation
In order to protect the environment, be sure to pump down when
relocating or disposing of the unit.
1
Remove the valve lid from liquid stop valve and gas stop valve.
2
Carry out forced cooling operation.
3
After 5 to 10 minutes, close the liquid stop valve with a
hexagonal wrench.
4
After 2-3 minutes, close the gas stop valve and stop forced
cooling operation.

Wiring
All wiring must be performed by an authorized electrician.
WARNING
Do not use tapped wires, stranded conductor wires
(see caution 1), extension cords or connections from
a star system, as they may cause overheating,
electrical shock or fire.
Do not use locally purchased electrical parts inside
the product and do not branch the power for the drain
pump, etc., from the terminal block. Doing this may
cause electrical shock or fire.
Be sure to install an earth leakage breaker. This unit
3
uses an inverter, which means that an earth leakage
breaker capable of handling high harmonics needs to
be used in order to prevent malfunctioning of the earth
4
leakage breaker itself.
Use an all-pole disconnection type breaker with a
4
contact separation of at least 3 mm in between all poles.
Equipment complying with EN/IEC 61000-3-12
Do not turn ON the safety breaker until all work is completed.
1
Strip the insulation from the wire (20 mm).
2
See caution 2.
Connect the connection wires between the indoor and outdoor
units so that the terminal numbers match. Tighten the terminal
screws securely. We recommend a flathead screwdriver to
tighten the screws.

(See figure 4)
If the length of a connection wire is:
2
≥10 m, use 2.5 mm
wires
2
<10 m, use 1.5 mm
wires.
Make sure that wiring connections of each
individual indoor unit (room A, B, ...) match
the corresponding piping connections on the
outdoor unit refrigeration ports (A, B, ...).
In case the use of stranded conductor wires is
unavoidable for one reason or another, make sure
to install round crimp-style terminals on the tip.
Place the round crimp-style terminal on the wire up
to the covered part and fasten the terminal with the
appropriate tool.

When connecting the connection wires to the
terminal board using a single core wire, be sure to
perform curling.
Not executing the connections properly may
cause heat and fire.
