Venting the Oil Pump
(See 3.1-6). If after the start of the compressor no oil pressure builds up, venting the oil pump may be
necessary, especially after maintenance and repair work. It may also be necessary if the unit has been
operated in the wrong direction of rotation.
1. With the unit running, open the condensate drain valves.
2. Open Oil Pump Vent Plug (2) and wait until oil comes out bubble free.
3. Replace Oil Vent Plug.
