Installation and maintenance
Installation
Pump should be mounted in a dry, cool
ventilated location.
Pump may be mounted in any position
without loss of efficiency; however, it is
suggested that the pump head be down if
vertical mounting is desired. Mount motor
as close as possible to power source to
obtain full voltage.
The pump should be installed so that the
motor is protected from rain, wash down
or bilge water.
Please note that pump body can be turned
180° in relation to motor. This changes
flow direction.
When using a vac-on-switch, mount it
on the connection on the inlet side of the
pump. When using a pressure switch,
mount it on the connection on the outlet
side of the pump.
Don’t handle diesel fuel or other mineral
oils with this pump. (For these liquids use
pump type F4B-19)
This pump cannot run against a closed
outlet. Risk for overheating.
