Installation; Electrical Installation; To Remove Or Replace Power Cartridge - Johnson Pump L450 Instruction Manual

INSTALLATION

Please follow the installation
instructions carefully to assure
maximum efficiency in your
bilge pump operation.
1. Mount the pump in the lowest
point of the bilge.
2. Select a point where the bilge
water is to be pumped over-
board as high as possible
above the water line and at
the shortest distance from the
pump. Install a 3/4" thru-hull
fitting (L750 – 1.1/8").
3. Fasten a 3/4" (L750 – 1.1/8")
fuel resistant hose from the
pump outlet to the thru-hull
fitting. Avoid sharp bends or
loops. Support the hose if
necessary.
Note: In order to prevent air
lock is important that the
hose not be allowed to dip
below the pump outlet. The
hose should be constantly
rising.

Electrical installation

1. Connect the brown wire to
the positive (+) terminal of
the battery.
2. Connect the black wire to
the negative (-) terminal of
the battery.
3. Do not cut back insulation
more than necessary. Insula-
tion or cable sheathings have
to be removed in such a way
that they end well above the
highest bilge water level. The
wire connections should be
sealed with a marine sealant
to prevent wire corrosion.
To remove or replace power
cartridge
See page 21
1. Lift tab and rotate the two
fins in a counter clockwise
direction and lift out.
2. To reinstall, first make sure
that the seal is properly
located. Coat the seal with
a light film of vegetable oil
or mineral oil, then align the
two cams on either side of
the power cartridge with the
two slots in the outer housing.
Press down and twist in a
clockwise rotation. To ensure
that the power cartridge is
properly located, twist tins in
a counter clock-wise direction
without lifting tab. Cartridge
should stay in place.
