To change the oil, the pump must be switched o ff
and ventilated to reach atmospheric pressure.
Open the oil drain valve and drain the oil. When
the oil stops draining, close the drain valve.
Start the pump again for a few seconds. Stop
the pump once again, and then reopen the drain
valve and discharge any remaining oil. Close the
drain valve.
After changing the oil fi lter (see Section 6.2.3),
fi ll the pump with the recommended vacuum oil
through the oil fi lling port, observing “MAX” and
“MIN” position on the oil level sight glass.
6.2.3 Automotive-Type Oil Filter
The pump is equipped with an automotive-type
oil fi lter. See Figure 6.1 for location.
Replace the oil fi lter when changing the oil. After
draining the oil, remove the oil fi lter and replace
it with a new one using a BeaconMedæs oil fi lter.
Make sure to tighten the fi lter securely against
the aluminum sealing surface so that leaks will
not occur.
6.2.2 Oil Level
Check the oil level daily by observing the built-
in sight glass. Each pump requires the proper
oil to operate correctly (see Section 6.2.1 for
the correct oil types). The oil should be changed
every 2,000 hours of operation. The oil will need
to be changed more frequently when operating
at ambient temperatures above 105°F.
Oil level readings should be done only when the
pump is turned o ff . Oil can be added to the oil
fi ll port if the pump is shut o ff and the circulating
oil has su ffi cient time to return to the oil sump.
During operation, the oil might appear foamy,
which is a normal phenomenon with aerated
oil. The technical data in Table 6.2 gives the
approximate quantities of oil required for each
pump. The oil capacity chart should only be used
as a guide, since oil capacity may be slightly lower,
depending on whether the pump was fi lled
previously, and whether all components such as
oil fi lter, oil lines, etc. were allowed to completely
drain. Use only the sight glass reading for proper
level. Never over fi ll.
CAUTION:
Oil and used oil must be disposed of
corresponding with the relevant health,
safety and environmental laws.
NOTE:
It is important to completely drain oil from
the pump, if changing brands.
WARNING:
Insu ffi cient oil quantity in the pump has the
potential, under certain conditions, to lead to
self-ignition of the remaining oil in the pump.
WARNING:
Do not add oil while the pump is running
since hot oil vapor may escape through the
oil fi ll port.
