Installation Procedure Electric wiring
ELECTRICAL WIRING
(1) Cut the wire end with a wire cutter or wire-cutting pliers, then strip the insulation to about 15/16"(25mm) to expose the
solid wire.
(2) Using a screwdriver
, remove the terminal screw(s) on the terminal board.
(3) Using pliers, bend the solid wire to form a loop suitable for the terminal screw.
(4) Shape the loop wire properly, place it on the terminal board and tighthen securely with the terminal screw using a
screwdriver.
B.For strand wiring
(1) Cut the wire end with a wire cutter or wire-cutting pliers, then strip the insulation to about 3/8"(10mm) to expose the
solid wire.
(2) Using a screwdriver
, remove the terminal screw(s) on the terminal board.
(3) Using a round terminal fastener or pliers, securely clamp a round terminal to each stripped wire end.
(4) Position the round terminal wire, and replace and tighten the terminal screw using a screwdriver.

After passing the connection cord and power cable through the insulation tube,
fasten it with the cord clamp.
Use VW-1, 0.5 to 1.0 mm thick, PVC tube as the insulation tube.
Fix connection cord and power cable at the cord clamp

Connect wiring to the terminals
(1) Remove the cord clamp.
(2) Process the end of the connection cords to the dimensions shown in wiring diagram.
(3) Connect the end of the connection cord fully into the terminal block.
(4) Fasten the connection cord with a cord clamp.
(5) Fasten the end of the connection cord with the screw.

ARNING
The power cable and connecting cable are self-provided.
Always use a special branch circuit and install a special receptacle to supply power to the room air conditioner.
Use a circuit breaker and receptacle matched to the capacity of the room air conditioner.
The circuit breaker is installed in the permanent wiring. Always use a circuit that can trip all the poles of the wiring and
has an isolation distance of at least 3mm between the contacts of each pole.
Perform wiring work in accordance with standards so that the room air conditioner can be operated safely and positively.
Install a leakage circuit breaker in accordance with the related laws and regulations and electric company standards.
The power source capacity must be the sum of the room air conditioner current and the current of other electrical
appliances. When the current contracted capacity is insufficient, change the contracted capacity.
When the voltage is low and the air conditioner is difficult to start, contact the power company the voltage raised.
CAUTION
DANGER OF BODILY INJURY OR DEATH
TURN OFF ELECTRIC POWER AT CIRCUIT BREAKER OR POWER SOURCE BEFORE MAKING ANY ELECTRIC
CONNECTIONS.
GROUND CONNECTIONS MUST BE COMPLETED BEFORE MAKING LINE VOLTAGE CONNECTIONS.
