Electric Wiring - Haier AB242ACBEA Service Manual

5
In case of gas leakage, tighten
parts of pipe connection. If
No gas leakage?
leakage stops, then proceed
steps.
6
Detach the charge hose from the service port, open
2-way valve and 3-way. Turn the valve rod
anticlockwise until hitting lightly.
7
To prevent the gas leakage, turn the service port's
cap, the valve rod'd cap for 2-way valve and 3-way's
a lottle more than the point where the torque
increases suddenly.
8
After attaching the each caps, check the gas
leakage around the caps.
CAUTION:
If the refrigerant of the air conditioner leaks, it is necessary to
make all the refrigerant out, then charge the liquid refrigerant
into air conditioner according to the amount marked on the
name plate.
If needing to remove the refrigerant gas when installation or repair , please refer to the following procedures:
1. Cut off the power
2. (After confirming the power is cut off) pull the power cable plug terminals of the low-pressure pressure-switch out.
3. (After confirming the power cable terminals of the low-pressure pressure-switch is cut off) After powering on the unit again
and switch to COOLING mode,perform refrigerant gas removing according to the normal refrigerant gas removing procedure.
4. After finishing refrigerant gas removing , cut off the power , then insert the power cable terminals of the low-pressure
pressure-switch properly.

5. Electric wiring

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.
(1) Selection of size of power supply and interconnecting wires.
Precautions for Electric wiring
Electric wiring work should be conducted only by authorized personnel.
Do not connect more than three wires to the terminal block. Always use round type crimped
terminal lugs with insulated grip on the ends of the wires.
Use copper conductor only.
Select wire sizes and circuit protection from table below. (This table shows 20 m length
wires with less than 2% voltage drop.)

If it does not stop gas leakage, discharge
whole refrigerants from the serice port.
After flaring work again and vacuumize,

fill up prescribed refrigerant from the gas
cylinder.
