NOTE
The equipment manufacturer requires that the mineral oil lubricant be replaced with Polyol Ester Oil. A
"Retro-Fit Test Kit" has been developed to provide a simple means of determining the level of mineral oil
remaining in the system following change out to an ester based lubricant. Continued proper operation of
the system after retrofitting requires that the mineral oil content be reduced to low levels as prescribed by
the equipment manufacturer.

technical manual for equipment data on the external condensate drain line.
SECTION III. PRINCIPLES OF OPERATION
1-15. FUNCTIONAL DESCRIPTION.
a.
The compressor takes cold, low pressure refrigerant gas and compresses it to a high temperature, high
pressure gas. This gas flows through the metal tubing to the condenser coil and receiver. Refer to Figure 1-
5 for the refrigerant schematic.
