Wiring and grounding must comply
with national and local codes.
Wiring
Important Safeguards:
- Check the unit nameplate for
electrical rating. Be sure wiring is
according to local codes and wiring
system diagram.
- A power supply disconnect and a
circuit breaker for overcurrent
protection should be provided in
the exclusive line.
- Connect all units electrically with
ground.
- Wiring should not touch refrigerant
tubing, compressor or moving
parts.
- The manufacturer will have no
responsibility for the problems
caused by unauthorized change in
the internal wiring.
- Connect wiring firmly.
- Use recommended wire length
and size.
Note
- Each country has their own field
wiring rules and regulations. Be
sure the installation complies with
local electrical codes.
- Nameplate ratings on indoor units
are for “one-to-one” system
installations only.

installed and there is no tool or
debris near or on top of the unit.
- Check the tubing and the
connections for leaks.
- Check that unit has a proper
ground wiring.
- Check for proper voltage and fuse
size.
- Check electrical wire size used is as
specified.

connection.
