How to wire
• Connect the indoor/outdoor connecting wires to the
terminal as identified with their respective numbers on
the terminal block of the indoor and outdoor units.
H07 RN-F or 60245 IEC 66 (1.5 mm 2 or more)
• When connecting the indoor/outdoor connecting wires
to the outdoor unit terminal, prevent water from
coming into the outdoor unit.
• Insulate the unsheathed cords (conductors) with
electrical insulation tape. Process them so that they
do not touch any electrical or metal parts.
• For interconnecting wires, do not use a wire joined to
another on the way. Use wires long enough to cover
the entire length.
• Wiring connections differ in conformance to EMC
standards, depending on whether the system is twin.
Connect wires according to respective instructions.
• Fix the indoor/outdoor connecting wires and power
supply wire with the supplied cord clamps or cable
ties.
<GM80, GM90>
• Fix the wires securely with the supplied cord clamps.
<GM110, GM140, GM160>
• Fix each wire tightly to the valve fixing plate with the cable
tie specified below. Measure the diameter of the wire to
be fixed, and fasten the wire with the supplied cable tie
(T50R-HSW from HellermannTyton) so that length A of the
surplus portion of the tie satisfies the following expression:
A = L - L
1 2
A: Minimum length of surplus portion of cable tie (mm)
L : Cable tie length (183mm for T50R-HSW)
1
L : Circumferential length of wire (mm)
2
L : Diameter of wire D (mm) × π
2
• Cut off the tie surplus portion (A) of the cable tie.
