Unit Initial Oil Charging

(Reference Figure 3-17)
10. At initial start up, compressor unit must be off and
depressurized prior to initial oil charging.
11. Using a properly selected oil pump, connect oil
pump to oil separator drain valve (10) (for oil sepa-
rator drain valve location, see Figure 3-16).
12. Open oil separator drain valve (10) and fill oil separa-
tor (1) to Maximum NON-Operating Level.
13. Once Maximum NON-Operating Level has been
reached, shut off oil pump, close oil separator drain
valve (10) and remove oil pump.
14. If equipped with remote oil cooler, refer to Priming
Compressor Units Equipped with Remote Oil Cooler
procedure (see Appendix G).

Priming Oil Lines and Compressor

Continue with the following steps to prime the oil lines
and compressor:
15. Make sure valves on oil circuit are in the open posi-
tion. In this case, make sure valves (2), (3), (5), (6)
and (7) are in the open position.
16. Energize compressor unit. Vission 20/20 will ener-
gize oil heaters.
17. Run oil pump (4) for 15 seconds only.
18. Wait minimum of 30 minutes to allow oil to drain
from compressor (8).
19. If compressor unit is not being started right away,
repeat steps 6 to 9 prior to starting.
