Physical Data

The Flooding Charges listed in the table above
reflect additional refrigerant required for split
condenser method of winter control above normal
summer operating charge and heat reclaim coil
requirements.

Note:

Condenser ambient should be noted when

determining the flooding charge.

• If above 65ÞF, add the specified amounts of

refrigerant when the system stabilizes after
start-up.

• If below 65ÞF but above the coldest expected,

some condenser flooding will already be occur-
ring and required additional charge will be
lower.

• If the coldest expected temperature is above

20ÞF, the flooding charge required will be less
than 50% of each condenser circuit.
