Maintenance 2
1. First Time Installation Check
Air and moisture trapped in the refrigerant system affects
the performance of the air conditioner by:
• Increasing pressure in the system.
• Increasing the operating current.
• Decreasing the cooling or heating efficiency.
• Congesting the capillary tubing due to ice build-up in
the refrigerant circuit.
• Corroding the refrigerant system.
To prevent air and moisture from affecting the air
conditioner’s performance, the indoor unit, as well as the
pipes between the indoor and outdoor unit, must be be
leak tested and evacuated.
Leak test (soap water method)
Use a soft brush to apply soapy water or a neutral liquid
detergent onto the indoor unit connections and outdoor
unit connections. If there is gas leakage, bubbles will form
on the connection.
