MAINTENANCE

1. Check Vacuum Pump Oil level before using the unit. If level is low, add. If oil turns

yellowish-brown, change oil.

2. Check service hose gaskets and o-rings for wear. Replace if necessary.

3. Check o-ring seal in Couplers for wear. Replace if necessary.

4. Check to make sure the oil drain system is function. Open drain valve and check for

failure to perform the oil drain function after each recovery, could lead to excessive

oil in the compressor and eventual compressor slugging.

Interconnection Hoses, Service Hoses and Coupler Maintenance

The AR2700 series uses brass to brass seal type fitting on the ends of the internal

interconnecting hoses. No hose gasket maintenance is required on the brass to brass

type of connections. Periodically inspect the refrigerant hose assembly, both service

hose ends and both service couplers (if used) inner O-ring. Replace the component(s)

if excessive wear or leakage is observed. Periodically leak-check all hose connection

points, hose ball valves, and service couplers (if used). Since this unit does pull a

vacuum in the recovery process, excessive Non-Condensable Gases (NCG's) could be

sucked into the system and placed in the storage tank.
