• 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.
