ELECTRICAL WIRING
WARNING
• Electrical wiring should be made with the proper wire
size and branch circuit protection by qualified personnel
according to the installation instructions. Property damage
and personal injury may result if the wiring and electrical
connections are not done properly.
• Wire size is based on full load current of the load and
distance from load to the circuit breaker. Work should be
done by a professional. Improper connections may lead
to personal injury or property damage.
• There must be a ground connection that complies with
local or national codes. Unreliable grounding may cause
electrical shocks. Do not connect the grounding line
to the gas pipe, water pipe, conduit, lightening rods or
telephone lines.
CAUTION
• Only copper wire should be used.
• The wiring for the branch circuit line is type Y. The 240
volt electrical supply should be connected to the N
and L terminals while
should be connected to the
ground wire. Electrical repairs should be done by trained
professionals.
• Connection kit power lines should be arranged according
to the installation instruction.
• The electrical wiring should be out of contact with any
high-temperature sections of tubing to avoid melting
insulation.
• Controller wiring and refrigerant tubing may be arranged
and fixed together.
• All power should be isolated before performing any
maintenance.
• Openings in the connection kit casing should be sealed
with caulking to avoid condensate leakage.
• Signal line and power line must be separate and
independent. Note the power line and signal line are
provided by the installer. Specifications for power lines
are: 14-2 w/ground paramters for signal line: 16-2
twsted-shielded with ground.
• Connection kits and outdoor units should be connected
to the power source separately. All connection kits must
share one single electrical source, but its capacity and
specifications should be calculated. Indoor & outdoor
units should be equipped with properly sized branch
circuit protection
• Multiple connection kits may be installed. Take proper
measures not to cross wiring and piping between
connection kits and outdoor units.
• Power up and commissioning should not be done before
all wiring and piping connections are verified and the
connection kit is completely installed.
