Charge Verification
CAUTION
NOTICE
Violation of EPA regulations may result in fines or other penalties.
Operating the compressor with the suction valve closed will void
the warranty and cause serious compressor damage.
CAUTION
Final Charge Adjustment
The outdoor temperature must be 60°F or higher. Set the room
thermostat to COOL, fan switch to AUTO, and set the temperature
control well below room temperature.
Purge gauge lines. Connect service gauge manifold to base-valve
service ports. Run the system (on low stage for two-stage units)
for 10 minutes to allow pressures to stabilize, then check
subcooling and/or superheat as detailed in the following sec-
tions.
Superheat = Suct. Line Temp. - Sat. Suct. Temp.
Subcooling = Sat. Liquid Temp. - Liquid Line Temp.
To prevent personal injury, carefully connect and disconnect
manifold gauge hoses. Escaping liquid refrigerant can cause burns.
Do not vent refrigerant into the atmosphere. Recover all
refrigerant during system repair and before final unit disposal.
