Oil Reclaim Filters
The oil reclaim system has a strainer on the eductor suction line and a filter on the cooler
scavaging line. Replace these filters once per year, or more often if filter condition indicates a
need for more frequent replacement. Change these filters by transferring the refrigerant charge
to a storage vessel or the condenser.
Inspect Refrigerant Float System
Perform inspection every 5 years or when the condenser is opened for service. Transfer the
refrigerant into the cooler vessel or into a storage tank. Remove the float access cover. Clean
the chamber and valve assembly thoroughly. Be sure that the valve moves freely. Make sure
that all openings are free of obstructions. Examine the cover gasket and replace if necessary.
See Figure 39 for views of both float valve designs. On the linear float valve design, inspect
orientation of the float slide pin. It must be pointed toward the bubbler tube for proper operation.
Inspect Relief Valves and Piping
The relief valves on this machine protect the system against the potentially dangerous
effects of overpressure. To ensure against damage to the equipment and possible injury to
personnel, these devices must be kept in peak operating condition.
