Maintenance

Vacuum Pump

Refer to the Vacuum Pump Operation and Service
Manual for specific instructions.
Lubrication We recommend that you use AEON PD-XD
Synthetic Blower Lubricant in both ends of the vacuum
pump for all operating temperatures. AEON PD-XD is
formulated especially for positive displacement blower
service to provide maximum blower protection at any
temperature. One filling of AEON PD-XD will last
several times longer than a premium mineral oil.
NOTE: AEON PD-XD is the oil that PROCHEM puts
in the vacuum pump at the factory. Topping off or
adding petroleum oil to synthetic oil is NOT
recommended.
If not using AEON PD-XD synthetic blower lubricant,
use oils with rust, oxidation inhibitors and anti-foam
additives.
1. Check the oil level daily to assure the proper level.
PROPER LEVEL cannot be overemphasized. Too
little oil will ruin bearings and gears. Too much oil
will cause overheating. Use the illustration as a
guide when adding oil.
To prevent rust from building up inside the vacuum
pump (if moisture exists) we have provided a lubrica-
tion cup on the front of the unit.
2. Run the unit at least 1 minute to remove any
moisture from the vacuum pump.
3. Fill the lubrication cup with water displacing lubri-
cant, for 5 seconds while the unit is running and the
vacuum inlets are sealed. Do this at the end of
each working day.

4. Drain, flush and replace oil every 1500 hours or
yearly, whichever comes first. Change oil more
frequently if inspection so indicates. With AEON
PD-XD synthetic lubricant, perform the oil change
maintenance every 4500 hours or every 2 years,
whichever comes first.
Vacuum pump oil capacities are as follows:
Shaft end = 1.25 pints
Gear end = 2.0 pints
5. Vacuum pump lubrication is vital to performance of
the pump. Failure to follow the maintenance
schedule can lead to permanent damage to your
blower.
Vacuum Inlet Filter (In Waste Tank)
1. The vacuum filter in the waste tank should be
removed and cleaned daily. If this is done, the filter
will last for a long period of time.

Vacuum Relief Valve

1. While the unit is running at full RPM, block the
airflow at the vacuum inlet connection and read the
vacuum gauge. If adjustment is required, shut the
unit down and adjust the vacuum relief valve
locking nut tension. Start your unit and repeat
above procedure. Repeat this process until the
relief valve opens at 13" Hg.
