Note: Before installation with electrical
control systems, check that equipment
to be used is of sufficient rated capacity
to accept ampere draw of motor. Low
voltage will cause motor to overheat.
Other electrical devices, eg switch, circuit
breaker, must be installed between the pump
and the positive (+) lead on the battery (on
the red wire).

* The wire length is the total distance from the
battery to the pump and back to the battery. It
is recommended to use a relay to shorten the
main leaders.
When the pump is used as bilge pump
Max total head 6 m.
The pump must be installed so that the
motor is protected from splash from
bilge water.
The pump must be fitted with a strainer
or other means of preventing debris from
entering the pump.
Self-priming
Pump is self-priming up to 4 m. Intake
lines must be air-tight to ensure self-
priming. Note: Pump will prime when
impeller is dry but suction lift up to 4
m is only obtainable when impeller is
lubricated with liquid being pumped or
Johnson Impeller lubricant.
For permanent installations where suc-
tion lift exceeds 4 m, a foot valve should
be used to assure priming on start up.
continuous duty
For continuous duty 0,6 bar (60 kPa)
maximum head is permissible. Normal
working temperature of the motor may
reach approx. +80°C( surface tempera-
ture) which may burn your skin.
dry running
Do not run dry for more than 30 seconds.
Lack of liquid will burn the impeller and
damage the seals.
If the pump is used for fuel oil transfer
it should be equipped with a vacuum
switch. When the liquid has been evacua-
ted the electric supply is automatically
switched off.
caution explosion Hazard
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.
caution. explosion Hazard.
Never operate a motor which in any way
has been manipulated and lost it's full
enclosure.
Temperature
Max ambient temperature: +60°C.
The life of the impeller depends on the
temperature of liquid being pumped.
