Product Description - Model Designation Chart

Note: Water- and Glycol-cooled units are shipped with a full refrigerant charge.

The necessary refrigerant charge is made up of three parts - that required to fill the unit, that required to fill the

liquid line, and that required to fill the remote condenser.

Abbreviations:

HGBV = hot-gas bypass valve
TFC = thermostatic fan cycling
FSC = fan speed control
HM = headmaster

Example:

A CM050 with hot-gas bypass has a DCM18 remote condenser with thermostatic fan cycling.

They are connected with 60 feet of 1/2” O.D. liquid line. The required amount of R-22 is

6.5 lb + (0.08 lb/ft X 60 ft) + 3.3 lb = 14.6 lb.
