Installation - Mechanical
Remote Evaporator Option
1. To determine the appropriate charge, first refer to the General Data Tables in Sec-
tion 1 to establish the required charge without the field-installed piping.
2. Next, determine the charge required for the field-installed piping by referring to
Table 16.
3. Sum the values of step 1 and step 2 to determine the circuit charge.
NOTE: The amounts of refrigerant listed in Table 16 are per 100 feet of pipe.
Requirements will be in direct proportion to the actual length of piping.
Oil Charge Determination
The unit is factory charged with the amount of oil required by the system, without the
field-installed piping. The amount of the additional oil required is dependent upon the
amount of refrigerant that is added to the system for the field installed piping.
Use the following formula to calculate the amount of oil to be added:
Pints of Oil = [lbs of R-134a added for field-installed piping]/100
