Models 5 CFM 22.5 oz.
Slowly add oil until oil level
rises even with arrows on front of cover
line. Replace oil ll plug.
If oil is too low, you will hear air exit out of the exhaust. If the
oil level is too high, excess oil will be blown out the exhaust.
Pump oil should be changed after each use. If system is
heavily contaminated, oil may have to be changed several
times during evacuation.
After initial ll up, best to check oil level with pump running.
Designed for all pumps without internal shut-off valve
to isolate pump from system.
FLUSHING
If the oil is badly
contaminated, ushing
may be necessary. Slowly
pour 1/3 - 1/2 cup of new
vacuum pump oil into the
intake connection while
pump is running. Repeat as
required until contamination
is removed from oil reservoir,
pump rotors, vanes and
housing. Dispose of all oil
used in ushing of the pump.

SHUT-OFF VALVE
O-ring quick coupler valve
excellent for blanking off any
vacuum system. Excellent for
pressure up to 500 lbs

VALVE CORE REMOVAL TOOL
Specifically designed to valve
off the system to remove
valve core, these tools feature
a quarter turn ball valve shut-
off and O-ring seals.
IMPORTANT
1. After every evacuation while pump is
warm and oil is thin, place pump
on level surface and open oil drain.
Oil can be forced from the pump
by opening one intake and partially
blocking the exhaust with a cloth
while the pump is running. Do not
operate the pump for more than
5 minutes using this method.
2. Slowly add oil until oil levels rises even with arrows on
front of cover. Replace oil ll plug.
To reach a deep vacuum, the TradeProTM vacuum pump
needs clean, moisture-free oil throughout evacuation.
Care should be taken to avoid contact on skin and clothing
when changing oil. Used oil should be disposed of in a
leak-proof corrosive-resistant container.
After Evacuation, Oil
Contains Rust Forming
Water and Corrosive Acids.
Drain Immediately While
Pump Is Warm.

START-UP
Connect the vacuum pump to the system to be evacuated.
Typically a 2-valve or 4-valve manifold is used to connect to
both the high and lowside of the system. Connect the center
(yellow) hose with a 2-valve manifold to the vacuum pump’s
1/4” SAE are intake port or the 3/8” black hose with a 4-valve
manifold to the pump’s 3/8” SAE are intake port. A micron
gauge should be placed at the system using a valve core
removal tool with a side port. The valve core removal tool will
allow for faster evacuation by removing the valve core and also
provide a “shut-off” to do a rise test on the system. The micron
gauge may also be placed on the open port of the 4-valve
manifold.
Simply turn the rocker switch on back of pump to “on”. Check
to make sure oil level is even with the arrows around the sight
glass while pump is running. The manifold ports can now be
opened to evacuate the system.
SHUT-DOWN
Crack open unused port to break vacuum. Allow pump to run
2-3 seconds. Shut down and remove hose connections and
cap intakes. Once the pump is shutdown, ensure caps are
hand tightened and exhaust plug is reattached.
Note: Pump is not a valve and will not hold vacuum when shut off
IMPORTANT
DO NOT START PUMP BEFORE ADDING OIL
The following procedures will prevent oil from being drawn into
cartridge and creating hard startup.
Being even a teaspoon
low on oil affects the
ultimate vacuum and the
performance of the pump
