SINGLE STAGE VACUUM PUMP OPERATING INSTRUCTIONS

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.

WARNING! WEAR SAFETY GLASSES

FEATURES

• A check valve is built into

the suction line to prevent oil

backup in case of power

loss.

• A built-in device eliminates

oil mist and an oil-gas

separator at the air exhaust

outlet takes care of oil

contamination in the air

exhaust.

• Specially designed for low

temperature and low voltage

conditions to guarantee

normal starting in winter;

≥41˚F (≥5˚C) temperature

and ±10% rated voltage.

• Pump runs with extremely

high ultimate vacuum and

low noise.

EACH VACUUM PUMP HAS BEEN

FACTORY TESTED FOR CFM AND

MICRON PERFORMANCE.

DO NOT ATTEMPT TO OPERATE WITHOUT USING OIL!!!

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.

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 attempting to add oil.

b. Remove the rubber cap from the top of pump. (DO NOT USE DURING OPERATION) Unscrew oil ﬁll port.

c. Slowly add oil until oil level rises to the top of the Oil Level Line. Do not overﬁll with oil!

d. Replace oil ﬁll port.

OIL CAPACITY:

3 CFM = 12 oz. 6 CFM = 18 oz.

2. CHECKING OIL LEVEL

a. 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.

b. 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. CHANGING OIL

In order to reach the deep vacuum required, your vacuum pump needs clean, moisture-free 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 leak-proof 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.
