before restart.

Avoid overheating (e.g., due to hot process
gases). Maximum permissible temperature
range: see ”Gas inlet temperatures”, pg. 26.
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.

Important notes regarding the use of gas ballast
Gas ballast is a continuous purge to keep the pump’s in-
terior as clean as possible and to reduce the possibility of
condensation inside the pump.
