Connect the unit to specialized grounding device and make sure it is securely grounded. It’s a
must to install air switch and current circuit breaker that can cut off the power of the entire system.
The circuit breaker should include magnetic trip function and thermal trip function so that system can
be protected from short circuit and overload.
(9) Grounding Requirements.
1) Air conditioner belongs to class I electrical appliance, so it must be securely grounded.
2) The yellow-green wire inside the unit is a ground wire. Do not cut it off or secure it with
tapping screws, otherwise it will lead to electric shock.
3) Power supply must include secure grounding terminal. Do not connect the ground wire
to the following:
①
Liquid pipe;
②
Gas pipe;
③
Drain pipe;
④
Other places that are deemed as not secure by professional technicians.
(1) Before starting work, check that power is not being supplied to the indoor unit and outdoor unit.
(2) Match the terminal block numbers and connection cord colors with those of the indoor unit side. Erroneous wiring
may cause burning of the electric parts.
(3) Connect the connection cords firmly to the terminal block. Imperfect installation may cause a fire.
(4) Always fasten the outside covering of the connection cord with cord clamps (If the insulator is not clamped,
electric leakage may occur).
(5) Always connect the ground wire.
