CAUTION!
Danger of injury to personnel and material damage
The disregard of technical data during installation may lead
to personal injuries or damage to property.
–
Observe the technical data- refer to chapter "Technical
Data" and, where applicable, the operating instructions
of the accessories.
WARNING!
Warning of feed chemical reactions to water
Feed chemicals that should not come into contact with water
may react to residual water in the liquid end that may origi‐
nate from works testing.
–
Blow the liquid end dry with compressed air through the
suction connector.
–
Then flush the liquid end with a suitable medium through
the suction connector.
WARNING!
The following measures are an advantage when working with
highly aggressive or hazardous feed chemicals:
–
Install a bleed valve with recirculation in the storage
tank.
–
Install an additional shut-off valve on the discharge or
suction ends.
CAUTION!
Warning of feed chemical spraying around
PTFE seals, which have already been used / compressed,
can no longer reliably seal a hydraulic connection.
–
New, unused PTFE seals must always be used.
CAUTION!
Suction problems possible
The valves may no longer close properly using feed chemi‐
cals with a particle size of greater than 0.3 mm.
–
Install a suitable filter in the suction line.
