7.2 Start-up
Inspection prior to initial start-up
The following points must be checked prior to initial start-up:
Inspect the VacuStar WR and the entire system
Check the pipes for continuity and residues (remove blanks if
there are any)
Check the operating data on the rating plate.
Check whether the rotor shaft can be rotated by hand.
Check the function of the water stop valve (water supply
and/or cell ventilation).
Check the sense of rotation (switch briefly on/off). Observe the
arrow for the sense of rotation.
Fill in
process water (clean drinking water)
up to the
maximum mark on the reservoir. Bleed the circuit. Add
antifreeze according to manufacturer's specifications.
ATTENTION!
Risk of damaging the slide ring seal!
The slide ring seal will be damaged when the
machine runs dry, without liquid.
Therefore:
– Before the unit is started, the liquid ring pump
must always be approximately half full (shaft
centre) with liquid (refer to page 17, Fig. 5,
pos. 10).
Check the function of the safety valve (see page 28 ff,
chapter 6.7.1.).
Check the attachment screws.
(see page 25, chapter 6.4.)
Start-up
Proceed as follows during start-up:
Open shut-off devices (if installed).
Start the VacuStar WR drive.
Check the operating data.
Check the function of the installed cell ventilation.
The VacuStar WR must run smoothly when the suction valve
is closed.
