WARNING
Hazard of the pump head bursting due to excessive
pressure increase
Do not exceed max. permissible operating
pressure (see chapter 9).
Monitor pressure during operation.
If the pressure exceeds the maximum permissi-
ble operating pressure, immediately switch off
pump and eliminate fault (see chapter 7).
Only throttle or regulate the air or gas quantity in
the suction line to prevent the maximum permis-
sible operating pressure from being exceeded.
If the air or gas quantity in the pressure line is
throttled or regulated, make sure that the maxi-
mum permissible operating pressure is not ex-
ceeded.
Ensure that the pump outlet is not closed or
constricted.
When the pump is at a standstill the inlet and exhaust must be at
normal atmospheric pressure.
When the operation of the pump is interrupted by the thermal
switch, the pump will re-start automatically after cooling down.
Take all care necessary to prevent this leading to a dangerous
situation.
Diaphragm and valve plates are the only parts subject to wear.
Wear is usually indicated by a drastic reduction in the pneumatic
performance. When replacing parts proceed as described in sec-
tion 5.
Ambient conditions: see section 1.3.
