User Guide

NOTE: Perform the NCG check daily prior to using your machine. The NCG bleed valve

on the upper rear center of the machine allows manual venting of non-

condensable gases that may accumulate during the recovery process.

1. With the storage tank vapor port open, compare the readings on the 2 gauges mounted on

the side of the machine. Gauge A indicates the actual System Pressure - Gauge B

indicates virgin Sample Pressure.

2. If gauge A is 5 PSI or more higher than gauge B, open the NCG Bleed Valve and slowly

bleed off pressure until gauge A is within 5 PSI of gauge B then close the NCG Bleed Valve.

EQUIPMENT SERVICE AND MAINTENANCE

WARNING: Before any service operation can be performed, it is necessary to purge the

refrigerant from the machine system. DO NOT open unit components until all

refrigerant has been purged from the system.

PURGE PROCEDURE

1. Drain any recovered oil using the recovered oil drain valve on the side of the machine.

FILTER CHANGE PROCEDURE

IMPORTANT: Filter life is 30 hours. Change the filter every 30 hours regardless of the

moisture level shown on the moisture indicator. Use the hour meter

mounted on the control panel to track and determine filter change intervals.

NOTE: Replacement filter (part # FA1) includes new gasket.

1. Purge the system as described above.

2. Remove the 8 bolts from the filter housing cover, remove the cover, remove the old gasket

from the machined groove then remove the old filter core from the housing.

3. Lubricate the new gasket with ESTER oil, install it in the cover groove then install the new

filter core in the housing with the HOLE END DOWN.

4. Replace the filter cover on the housing and tighten the bolts to 15 ft. lbs. torque using a

crossing pattern.
