indoor and outdoor unit should be com-
plied with the following specifications
(Rubber insulation, type H05RN-F
approved by HAR or SAA).
If the supply cord is damaged, it must be
replaced by a special cord or assembly
available from the manufacturer of its
service agent. When the connection line
between the indoor unit and outdooor
unit and outdoor unit is over 40 m, con-
nect the telecommunication line and

Precautions when laying power wiring
Use round pressure terminals for connections
to the power terminal block.

Power wire
When none are available, follow the instruc-
tions below.
- Do not connect wiring of different thickness-
es to the power terminal block. (Slack in the
power wiring may cause abnormal heat.)
- When connecting wiring which is the same
thickness, do as shown in the figure below.
- For wiring, use the designated power wire and
connect firmly, then secure to prevent outside
pressure being exerted on the terminal block.
- Use an appropriate screwdriver for tightening
the terinal screws. A screwdriver with a small
head will strip the head and make proper
tighterning impossible.
- Over-tightening the terminal screws may break
them.
