Water ring vacuum pump preparation (FAM-xx-x-x-x-xx-W/WA-x …)
NOTICE
Operation without water
The water ring vacuum pump will be destroyed
►
The water ring vacuum pump requires water as its operating medium.
►
Check the water level before star-up, topping up the water if necessary.
►
Fill the water ring vacuum pump with clean tap water.
►
Do not use any deionized water
►
If there is a danger of freezing, add commercially available automotive
antifreeze to the water in the vacuum pump.
If no vacuum forms after switching on the FAM, the intake connection [N1.0] should
be filled with an additional 2-3 liters of water. To do this, release the transparent
suction hose from the support and fill in the water. Re-attach the hose afterwards.
During operation, the water filling level is monitored automatically by means of a
level switch built into the vacuum pump. A corresponding message will be outputted
on the display when the filling level reaches the MIN switch point.
Adding Water Manually:
Add clean tap water through the opening [N3.4] until the water level has reached the
lower edge of the opening. Seal the opening again afterwards.
