The washer and nut should be placed on the fitting on the internal side of the tank or on bottom side of the lid. Smooth
washer edges should touch the tank wall (or lid wall). Use one spanner to tighten the connection and the other spanner (or your
hand) to hold the fitting. Tighten the nut until you feel resistance. It is important to place the O-ring and the nut concentric.
Incorrect positioning may result in a lack of tightness in the chamber. Photo 5 shows the incorrect position of the sealing ring. Do
not tighten the O-ring too hard or you will deform it and lose its properties.

Photo 6: Air manifold correctly installed.
Photo 6 shows a correctly mounted air manifold on the tank wall. The green stopper plug, visible in the photo, is used to
protect the vacuum gauge against spilling glycerine during transport or assembly. It should be removed after all components of
the vacuum set have been assembled. Leaving the stopper plug in the vacuum gauge may result in incorrect pressure
indications.

Preparation of the vacuum pump.
1)
Before the first use necessarily fill the vacuum pump (Photo 7) with the oil provided with the set. To do that, place the
pump on the flat, horizontal surface, unscrew the red plug (1) and pour the oil through the oil feed hole. For some models of
pumps (when there is no red cap), the oil should be poured through the hole in the pump housing after the blue oil filter
cylinder (2) has been unscrewed. Oil pour gradually at the same time control the oil level by observing the oil sight glass (4).
Photo 7: Elements of the vacuum pump and correct oil level.
The pump delivered to the client is never filled with oil. A little amount of oil in the oil sight glass indicates
only the fact that the pump was tested before the shipment. The pump must necessarily be filled with oil
before use.
2)
Remove the plug (3), protecting the air filter, placed on the exhaust of the vacuum pump. Not applicable to the VP1RS-
0.5 model.
C.
Connection of elements of the vacuum set.
1)
Screw the connector tighten in the pneumatic hose to the vertical fitting on vacuum pump. Screw the connector gently
until the resistance is felt, using spanner.

2)
Put the spare end of the pneumatic hose on the barb of the ball valve in the chamber. Secure this connection using a
worm drive hose clamp.
3)
Remove the green plug of the rubber plug on the vacuum gauge.
