Installation Procedure
Optional: Fixing the outdoor unit to a wall with
a rack
Soft rubber designed to cut off vibration from
rack to wall. (not supplied with product)
Designed to cut off residual vibration from
outdoor unit to rack. (not supplied with product)
Anchor bolt
Base surface
20 mm
• Install a proper grommet in order to reduce noise
and residual vibration transferred by the outdoor unit
towards the wall.
CAUTION
• When installing an air guide duct, be sure to check the
following:
– The screws do not damage the copper pipe.
– The air guide duct is fixed firmly on the guard fan.
Step 4 Connecting the power cables,
communication cable, and controllers
You must connect the following three electrical cables to the
outdoor unit:
• The main power cable between the auxiliary circuit
breaker and the outdoor unit.
• The outdoor-to-indoor power cable between the
outdoor unit and the indoor unit.
• The communication cable between the outdoor unit
and the indoor unit.
CAUTION
• During installation, make first the refrigerant
connections and then the electrical connections. If the
unit is uninstalled, first disconnect the electrical cables
and then the refrigerant connections.
• Connect the air conditioner to the earthing system
before making the electrical connections.
NOTE
• Especially, if your outdoor unit is the one designed for
Russian and European markets, consult the supply
authority, if necessary, to estimate and reduce the
supply system impedance before installation.
