Electric Wiring - Haier AD242AMNAA Instruction Manual

INSTALLATION MANUAL FOR OUTDOOR UNIT
(6) Additional charge of refrigerant
Outdoor unit is precharged at a factory for the piping length up to 5m. Additional charge is not required
up to 5m.
Model
36,42 series
Heat
pump
24,28 series
Notes (i) Basic refrigerant charge amount means refrigerant amount when refrigerant piping length is 5m.
(ii) When the refrigerant piping length exceeds the length that additional refrigerant charge is not
required, charge additional refrigerant based on to the calculated amount of refrigerant per unit
piping length.
Example of additional charge amount calculation
Calculate the additional charge amount when the piping length is 25 m.
(25 - 5 ) x 0.06 = 1.2
Total length of the piping (one way) (m)
Additional charge amount of refrigerant =0.70kg(Calculate the amount in any case.)

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.)
