Checking Oil Level - MasterCool BLACK Serie Bedienungsanleitung

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.
WARNING:
1. Wear safety glasses
2. Do not evacuate combustible, explosive or poisonous gases.
3. Do not evacuate gases that corrode metal or react chemically with pump oil.
4. The temperature of evacuated gas shall not exceed 176˚F (80˚C) and ambient temperature shall be 41 - 140˚F (5 -
60˚C) in order to perform at maximum capacity.
5. Do not operate without oil.
6. Pump and motor can be extremely hot to the touch in high ambient temperature conditions.
7. Do not block vacuum pump exhaust.
CAUTION:
To reduce the danger of electric shock, keep the pump indoors and do not expose to rain.
DANGER:
1. Receptacle shall be well grounded, or else electric shock may be caused. Should power cord or plug require repair
or replacement, do not use the pump. If you cannot fully understand grounding instructions and have doubt whether
correct grounding is made, check with a professional electrician or service man. Do not change the structure of
attached adapter connector.
2. When pulling out power plug, make sure to pull the plug rather than the wire.
3. Do not place anything on the power cord. It may damage the wire.
4. Do not use broken plug or socket.
5. Do not pull out power plug with wet hand.
6. Do not pull out, insert power plug or turn on power switch where flammable gases may be present.
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!
1. Make sure the oil drain valve located below the front casing is closed before attempting to add oil.
2. Remove the exhaust muffler from the top of pump and insert the oil bottle into the exhaust port.
3. Slowly add oil until oil level rises to the top of the Oil Level Line. Do not overfill with oil!
4. Replace exhaust muffler.

CHECKING OIL LEVEL

1. Open the gas ballast valve (small brass fitting located next to the handle) one turn.
2. 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.
3. 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.
GAS BALLAST VALVE
The gas ballast valve must be opened 1/4 turn for the first part of the evacuation procedure. This will help to eliminate
moisture and extend the life of the vacuum pump. After about two minutes close the valve and continue the evacuation
procedure to reach ultimate vacuum. Failure to close the valve completely during the final evacuation will result in high
