Prevent internal condensation, transfer of liq-
uids or dust. The diaphragms and valves will
be damaged, if liquids are pumped in signifi-
cant amounts.
Check the pump regularly for external soiling
and deposits. Clean the pump if necessary
to avoid an increase of the pump’s operating
temperature.
In case of overload, the motor is shut down by
a self-hold thermal cutout in the winding.
Note: Only manual reset is possible. Switch
off the pump and disconnect from the power
source. Identify and eliminate the cause of fail-
ure. Allow the pump to cool down sufficiently
before restart.

Avoid overheating (e.g., due to hot process
gases). Maximum permissible temperature
range: see “Gas inlet temperatures”, pg. 24.
Do not start the pump if the pressure difference between
inlet and outlet ports exceeds max. 16.0 psi (1.1 bar).
Attempts to start the pump at higher pressure difference
may cause stalling and damage of the motor.
NOTICE
Make sure the fan’s air supply is adequate. Do
not place the pump on soft surfaces (e.g., rub-
ber foam) during operation. This may reduce
the air circulation in the pump housing and af-
fect the fan’s cooling effect. Check fan regu-
larly for dust/dirt. Clean fan guard grill if neces-
sary to avoid a reduction of ventilation.
