VACUUM PUMP
Refer to the Vacuum Pump Operation and
Service Manual for specific instructions.
Lubrication: We recommend that you use Roots
Synthetic Blower Lubricant in the vacuum pump
for all operation temperatures. This lubricant is
formulated especially for positive displacement
blower service to provide maximum blower
protection at any temperature. One filling of
Roots Synthetic oil will last many times longer
than a premium mineral oil.
NOTE: Roots Synthetic oil is the oil
which ESTEAM puts in the vacuum pump
at the factory. Topping off or adding
petroleum oil to synthetic oil is NOT
recommended.
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.
2. To prevent rust from building up inside the
vacuum pump (if moisture exists) we have
provided a lubrication cup on the front of the
unit.
First run the unit at least 1 minute to remove any
moisture from the vacuum pump. Next, fill the
lubrication cup with LPS-TKX, or a similar
lubricant, for 5 seconds while the unit is running
and the vacuum inlets are sealed. Do this at the
end of each working day.
3. Drain, flush and replace oil every 200 hours
or yearly, whichever comes first. Change
oil more frequently if inspection so indicates.
With Roots Synthetic lubricant, perform the
oil change maintenance every 500 hours or
once per year, whichever comes first.
4. Vacuum pump lubrication is vital to
performance of our pump. Failure to follow
the maintenance schedule in the
“Maintenance Schedule” can lead to
permanent damage to your blower.
WATER PUMP
1. Check the crankcase oil level daily to assure
the proper level. Use the illustration as a
guide when checking the oil level. If the
level has dropped, check for the source of
leakage and repair.
2. Change the crankcase oil with Cat Pump
Crankcase Oil, after the first 50 hours of
operation. Drain and refill the crankcase oil
with Cat Pump Crankcase Oil every 500
hours thereafter.
3. Other Cat approved oil equivalents are: Mobil
DTE 16, Amoco Rykow 68, and Shell Tellus
T68.
VACUUM INLET FILTERS
(IN WASTE TANK)
1. The vacuum filters in the waste tank should
be removed and cleaned daily. If this is
done, the filters will last for a long period of
time.
VACUUM RELIEF VALVE
While the unit is running at full RPM, block the
air flow 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
read the vacuum gauge. Repeat this process
until the relief valve opens at 14” Hg on a
Compact 45 and 12”Hg on a Compact 47.
