To Check System Refrigerant Charge
(Heating Mode)
Maintenance
The recommended method of addition or removal of
charge in the heating mode is by weight. The system op-
eration may be checked against the performance charts.
Remember, indoor airflow must be approximately 400
CFM per ton to compare operation to performance charts.
In some areas, with high humidity, the temperature ter-
mination may require adjustment for complete removal of
ice from the coil. For best economy, always set to the low-
est temperature that will keep the coil clear of ice.
NOTE: The term ice means hard but not frost. During nor-
mal operation, the coils may become coated with frost until
they are solid white. The temperature for the defrost should
be set so the frost and ice melt off completely without hard
ice building up on the coil.
Electrical Shock Hazard.
Shut off electric power at fuse box or service pan-
el before making any electrical connections,
Failure to shut off electric power can result in,
property damage, personal injury and/or death.
Condensate Drain
During the cooling season check at least monthly for free
flow of drainage and clean if necessary.
Cleanliness
These tips will help you keep your air conditioner looking
better and working more efficiently:
1. Free air flow is essential. Keep the outdoor coil clean
and free of restrictions. Keep fences, shrubs, snow
drifts and any other obstructions at least two feet from
all coil air inlets.
