Installation recommendations
Installation
Pump may be mounted in any position with-out
loss of efficiency; however, it is suggested that
the pump head be down if vertical mounting is
desired. The pump must be installed below the
holding tank or bowl discharge outlet. Mount
motor as close as possible to power source to
obtain full voltage.
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.
Electrical installation
The pump must be installed according to
ISO 10133 (Small craft - Electrical system - Extra
low voltage DC installation for continuous cur-
rent). Note: The fuse must be ignition protected.
The fuse works as over-current protection, and
protects the motor from overloading and rotation.
Incorrect fuse size may cause fire.
If the pump is connected with separate earth lead,
this should be yellow/green and connected to the
motor base.
See the wiring scheme for correct installation.
Negative wire must be black.
Choose wire size in accordance with total
wire length (see table).
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.
The perfect disposer for the
lavatory unit in boats and
recreational vehicles
The SPX FLOW Johnson Pump macerator pump
TA3P10-19 takes care of toilet waste.
A rotary cutter shreds waste before it is pumped out
through the discharge hose.
The pump can be connected directly to the bowl
discharge outlet or holding tank.
Note: Use unbleached lavatory paper only. Do not
run pump dry. Must not be used for continuous duty.

Disassembly
1. Remove nut, washer and housing.
2. Remove cutter. Use a 7 mm open-ended
spanner to hold shaft behind cutter.
Turn cutter anti-clockwise.
3. Remove the wear plate, the O-ring and
the gasket.
4. Withdraw impeller.
5. Remove screw (10) .
6. Separate body from motor.
7. Remove screw (13) and lip seal.
Assembly
1. Fit lip seal and screw (13) in the body.
Note! The spring of the seal must face
towards the impeller.
2. Fit body to motor.
3. Fit screw (10).
4. Lubricate the impeller with vaseline to
avoid dry running and fit it with a
rotating movement in the intended
direction of the impeller rotation
(clockwise).
5. Fit the gasket and wear plate.*
6. Mount cutter on motor shaft. Use a 7 mm
open-ended spanner to hold shaft and
turn cutter clockwise.
7. Mount the O-ring in the housing.
8. Mount housing, washer and nut.*
* Note! Check that the inlet passage of the
gasket, wear plate and housing are seated
properly on the body.

* The wire length is the total distance from the
battery to the pump and back to the battery.
Dry running
Do not run dry for more than 30 seconds. Lack of
liquid will burn the impeller and damage the seals.
Caution
Do not pump gasoline, solvents, thinners, highly
concentrated or organic acids. If corrosive fluids
must be handled, pump life will be prolonged if
flushed with water after each use or after each
work day.
Temperature
Max ambient temperature + 60°C.
The pump can not be run continuously.
The motor is equipped with built in thermal
protection to prevent the motor from overheating.
The protection is automatically restored when the
motor is cooled.
Freezing weather
Glycol based anti-freezes can be used but do not
use petroleum based anti-freeze compounds.
Gasket
Use standard gasket. A thicker gasket will reduce
priming ability. A thinner gasket will cause impeller
to bind.
