Installation
NOTES
1. Shows only in case of protected pipes. Use H07RN-F in
case of no protection.
2. Insulated thickness : 1mm or more.
3. If the wiring is in a place where people it can be easily
touched by people, install an earth leakage breaker to pre-
vent electric shock.
4. When using an earth leakage breaker, make sure to select
one useful also to protection against overcurrent and short-
circuit.
When using an earth leakage breaker only for earth device,
make sure to use a wiring interrupter together.
• The length of the transmission wiring and remote controller
wiring are as follows.

10. WIRING EXAMPLE
10-1 HOW TO CONNECT WIRINGS
• Wire only after removing the control box lid as shown in
Fig. 17.

Clamp the wiring sheaths (accessory (10))
• Make sure to let a wire go through a wire penetration area.
• After wiring, seal the wire and wire penetration area to prevent
moisture and small creatures from the outside.
• Wrap the strong and weak electric lines with the sealing
material (12) as shown in the figure below.
(Otherwise, moisture or small creatures such as insects from
the outside may cause short-circuit inside the control box.)
Attach securely so that there are no gaps.

CAUTION
• When clamping the wiring, use the included clamp material
(9) and (10) as shown in the Fig.17 to prevent outside pres-
sure being exerted on the wiring connections and clamp
firmly.
• Be sure to attach power supply wiring and earth wire to the
control box with the clamp.
• When doing the wiring, make sure the wiring is neat and
does not cause the control box lid to stick up, then close the
cover firmly. When attaching the control box lid, make sure
you do not pinch any wires.
• Outside the air conditioners, separate the weak wiring (remote
controller and transmission wiring) and strong wiring (earth
wire and power supply wiring) at least 50 mm so that they do
not pass through the same place together. Proximity may
cause electrical interference, malfunctions, and breakage.

Clamp (for fixing in place)
Match up the wiring sheath with
the fixing clasp with the clamping
material for preventing slippage on
the power supply side and clamp
(accessory (9)).
