2. Mounting
1) Set the PKS as near as possible to the vacuum equipment, insuring that
water and exhaust connections can be conveniently made.
2) The PKS should be mounted on a rigid foundation such as a concrete floor,
and made level by shimming or grouting if necessary, and bolted in place.
[Refer to Fig. 7, 8, 9]
Note: Excessive environmental dust, acid fumes, solvent vapor etc., should be
avoided.
3. Oil Filling
[Refer to Fig. 7, 8, 9]
1) Remove the “Oil-Filler Cap” (See Fig. 4
〜
6) and make sure that the “Oil
Drain Valve” is closed.
2) Fill the pump with ULVAC's specified oil (ULVOIL-R-7) until the oil level can
be observed at the oil level window attached to the side of the pump. (See Pig. 4
~ 6)
The optimum level is 5 mm above the lower line of the window glass while the
pump is running. This level will change slightly after the first few hours of use.
In most cases oil should be added after operating the pump for a short while.
Note: If the amount of oil contained in the pump is mot appropriate, the
performance of the pump will be unsatisfactory.
