3. Connect the bearing housing circulating oil level drain hole
on alternate oil gauge hole for draining to the return on the
OLF System. Note: Drain piping should be vented and of
adequate size to drain oil from the bearing at the specified
flow rate. The housing drain must be directed straight down
into a return drain sloping away at a 15° or greater angle. Fill
the bearing with oil to its recommended level (see SLEEVOIL
installation manual).
4. Connect the 1 HP electrical motor to 400 volts 3 phase
power source. 9. Fill the bearing with oil to its recommended
level (see SLEEVOIL installation manual).
5. Connect the 1 HP electrical motor to 400 volts 3 phase
power source.

6. Start and allow the OLF System to circulate. Be sure to
monitor the oil level in the reservoir to ensure that the oil
returns from the bearing housing.
7. Monitor the oil sight gauge on the bearing housing to ensure
that the oil level is maintained. Also monitor the pressure
gauge on the OLF System. It should read less than 10 PSI at
start-up.
8. If the oil level in the bearing housing rises this means that
the oil is not returning back to the oil level filtration unit. This
can be due to not using the right size return line or due to
improper location of the unit with respect to the bearing. In
this case call DODGE.
9. If the oil level in both the OLF System and the bearing are
stable, start the main fan. Continue to monitor the oil level in
both the bearing and the OLF System to ensure that the oil
still flows under the dynamic condition.
10. It is important to note that the drain return from the bearing
housing is above the sump oil level in the housing, therefore
the bearing will receive the oil it needs even if the OLF
System is shut down or stops.
MAINTENANCE:
Periodically check the oil level in the bearing housing and
the OLF System to ensure proper operation. When the filter
becomes plugged, the oil pressure gauge reading should rise.
Replace the filter element when the pressure reaches 18-20 psi.
The bypass is set at a different pressure of 25 psi.
