Charging The Refrigerant - LG MW122C4 Installation Manual

CHARGING THE REFRIGERANT

If the amount of refrigerant level is low, the appliance
would provide low performance. Charge the
refrigerant for proper operation.
• Refer to the label attached to the side of the
appliance to confirm the type and amount of
refrigerant.
• Charge the refrigerant through the gas service
valve (larger pipe).
1
Connect the low-pressure hose of the manifold
gauge to the core valve of the gas service valve.
2
Open both the gas service valve and the liquid
service valve of the outdoor unit.
• Rotate the valves to counter-clockwise using a
hexagon wrench.
3
Connect the charging hose of the manifold
gauge to the refrigerant cylinder.

Charge Using the Refrigerant Cylinder
without a Siphon
• This is usually applied to R410A. Charge
the refrigerant (liquid phase) by inverting the
refrigerant cylinder.
4
Charge the refrigerant by adjusting the low-
pressure valve of the manifold gauge.
• Refer to 'Suggested Amount of Refrigerant
Charge'.
5
After charging the refrigerant, close the low-
pressure valve of the manifold gauge and
separate the connected low-pressure hose from
the outdoor unit.
NOTE
• If charging a mixed refrigerant like R410A, charge
from the bottom after removing all the refrigerant
in the cylinder.
• The handling of the refrigerant must comply with
national regulations.
