OPERATING INSTRUCTIONS
DO NOT ATTEMPT TO OPERATE WITHOUT USING OIL!!!
In order to make the best use of your investment, familiarize yourself with the
new features and operating instructions before starting pump. Routine care and
maintenance of your vacuum pump will give you years of reliable service.
Retain shipping box and packing material for use if factory
warranty service is required.
IMPORTANT!: Use oil specifically refined for Deep Vacuum Pumps. Use
of oil not refined for Deep Vacuum Pumps and/or operating with
contaminated oil will void warranty.
Each vacuum pump has been factory tested for CFM and micron performance.
The serial number has been recorded. Complete and mail the warranty form
immediately to validate your warranty!

OPERATING INSTRUCTIONS
1. OIL FILL
This vacuum pump has been tested at the factory and shipped with only trace amounts
of oil. OIL MUST BE ADDED BEFORE OPERATING! Failure to add oil will damage
cartridge and void warranty!
a. Make sure the oil drain valve located below the front casing is closed before at
tempting to add oil. (See ref. #4 in parts breakdown.)
b. Remove the large brass oil fill plug from the top of pump and insert the oil bottle
into the fill port. (See ref. #5 in parts breakdown.)
c. Slowly add oil until oil level rises to the top of the Oil Level Line.
Do not overfill with oil!
d. Replace the oil fill plug.
CAPACITY: 1.5 CFM (42 LIT/MIN) = 10 oz.
2. CHECKING OIL LEVEL
a. Open the gas ballast valve (small brass fitting located next to the handle) one turn.
Do not remove!
b. Start pump and run with intake port capped for about two minutes. Observe the oil
level with the pump running. The oil level in the sight glass should be even with the
level line.
c. If the level is low, open the intake port and run pump for 15 seconds, stop pump
and observe oil level again. Add a small amount of oil as needed.
3. GAS BALLAST VALVE
The gas ballast valve must be 1/4 turn to fully opened for the first part of the evacuation
procedure. After about two minutes close the valve and continue the evacuation procedure to reach ultimate vacuum. FAILURE TO OPEN THE GAS BALLAST VALVE MAY
RESULT IN DAMAGE TO YOUR CARTRIDGE. Failure to close the valve during evacuation
will result in poor vacuum performance.
During the first stages of evacuation, vapors are highly concentrated. Unfortunately,
some vapors will condense into a liquid and mix with the oil, thus reducing the oil’s
ability to produce a deep vacuum. The GAS BALLAST VALVE emmits a controlled
amount of dry air into the pump during compression to minimize this effect and keep oil
relatively clean during the first part of the evacuation.
Periodically remove the Gas Ballast Valve Needle and clean or replace the O-ring. Clean
mating surfaces and lightly coat with vacuum pump oil before securely retightening.
4. CHANGING OIL
In order to reach the deep vacuum required, your vacuum pump needs clean, moisturefree oil during evacuation. Dirty oil becomes a mixture of corrosive acids and water that
effects the pump’s ability to pull a deep vacuum. Left sitting in the pump, this sludge will
rust and erode internal surfaces...shortening the pump’s life.

Care should be taken to avoid contact of oil with skin or eyes. OIL MAY BE HOT!
Used oil should be properly disposed of in a leakproof corrosive-resistant
container according to local regulations.
a. After every evacuation, while the pump is warm and oil is thin, take a small sample
of oil from the drain port.
b. If the oil is contaminated, drain the oil by placing the pump on a level surface and
opening the oil drain valve. Catch the waste oil in a container and properly dispose
of it.
c. If the pump has been sitting for more than one month, the oil is considered
contaminated regardless of appearance and should be changed as outlined above.
d. To add oil, close drain, remove the oil fill cap and fill to the Oil Level Line with fresh
oil.
5. INTAKE CONNECTIONS
Replace all caps and finger-tighten. Do not use caps with damaged or missing O-rings
and always store vacuum pump with capped ports to prevent dirt and moisture
contamination.
6. PUMP MOTOR
• The PUMP and OIL must be above 30˚F.
• The line voltage must be equal to the rating on the motor nameplate + / - 10%.
• Normal operating temperature is approximately 160˚F, which is HOT to the touch!
Line voltage and ambient temperature will affect the normal operating temperature
somewhat. Your vacuum pump is designed for continuous duty and will run for extended
periods without overheating. The motor has an automatic resetting overload protection
feature. If the motor will not restart the pump after shut-off, it may have opened the
thermal protection. Disconnect the pump from the system, wait about 15 minutes for the
motor to cool down and then try again.
RETURNING A PUMP
Please fax a request for a return authorization number to 973-252-2455.
This applies to both warranty and non-warranty service!
Pumps returned for service without a return authorization number will not be accepted.
In your fax, include your NAME, ADDRESS and PHONE NUMBER along with a detailed
explanation of the problem. We will contact you (i.e. your phone number) to discuss your
problem and determine if you have to return your pump, or if we can troubleshoot it over the
phone.
If you have to return your pump, we will issue you an RMA#. Then, please follow the instructions below.
• Drain oil, cap all ports and place tape over the exhaust port located on the end of the pump
handle. If you fail to do this, your pump will not be accepted and it will be returned!!!
• Use the original shipping box and inserts if available. Shipping damages are impossible to
claim on used machinery.
