ENGLISH
Caution
Do not pump gasoline, solvents,
thinners, highly concentrated or
organic acids. If corrosive fluids must
be handled, pump life will be pro-
longed if flushed with water after each
use or after each work day.
Temperature
Max ambient temperature: +60°C.
The life of the impeller depends on
the temperature of liquid being
pumped. Temperatures between +5°C
and +60°C give normal life. Higher or
lower temperature will reduce the life.
Freezing weather
Drain unit by loosening the endcover.
Glycol based anti-freezes can be used
but do not use petroleum based anti-
freeze compounds.

Accessories
Vacuum switch 09-45053
• For automatic shut off operation.
• To prevent pump damage.
The vacuum switch works with all self-
priming impeller pumps and should be
used for e.g. bilge pumping/emptying
of tanks to prevent the pump from
running dry.
The vacuum switch automatically shuts
the pump off when the bilge/tank is
dry. With the switch fitted, you can
start the pump by remote push button
or manually by depressing lever on the
switch.
The switch is not
ignition protected.
