5.2 PUMP ASSEMBLY AND DISASSEMBLY
1. Disassembly
- Back off the end cover screws, re-move the end
cover and o-ring.
- Pull out the impeller using a Jabsco impeller
removal tool, shown below.
- Back off and remove the screws holding the body
to the motor.
- Remove the lip seal from the body.
- Do not disassemble the motor.
2. Assembly
- Moisten the new lip seal, and mount the seal
with the lip facing towards the impeller.
- Lubricate the motor shaft and fit the body to
the motor by tightening the motor screws.
- Ensure the body and impeller is lubricated.
- Fit the impeller with a rotating movement in
the intended direction of the pump rotation.
- Lubricate the o-ring, fit it in position and fasten
the end cover screws to the body.
- Torque value for end cover to body screws: 30
– 40 lbf.ins / 3.4 – 4.5 Nm.
- Torque value for body to motor screws: 21 – 28
lbf.ins / 2.4 – 3.1 Nm.
5.3 ELECTRICAL CONFIGURATION
- It is the responsibility of the installer to perform
the correct installation.
- Make all electrical connections in dry locations,
connections in humid environments should be
sealed to prevent corrosion.
- Protect the circuit with a correctly rated fuse
or circuit breaker in the red positive (+) lead
as close as possible to the power source (see
section 8 for recommended fuses).
- Ensure fuses for the Ballast King pump are slow
burning, being capable of handling the start-
up and reversing current.
- Connect the black motor wire to the negative
(-) battery terminal.
- Inadequate voltage at the motor terminals
when the pump is running (not less than 95%
below rated voltage at full load) due to partially
discharged batteries or insufficient cable size
may result in blowing fuses, failure to start or
poor pump performance.
- The fuse must be ignition protected.
- The motor is equipped with built in thermal
protection to prevent it from over-heating.
- The protection is automatically restored when
the motor is cooled.
- Before installation with control systems, check
the equipment to be used is of sufficient rated
capacity to accept ampere draw of motor.
- Choose the wire size in accordance with total
wire length.
- There is a motor thermal cut out switch for
protection.
- All Ballast King wiring and connections to be
carried out in accordance to ISO 10133.
WARNING!
When terminated at the power supply using
permanent connections, red leads should be
terminated to the positive and black to the
negative. If reversed pump will run in reverse.
- Install the Ballast King pump in accordance to ISO
10133.
- If installed in a vertical position, the motor must
be above the pump head, shown below. This will
prevent liquid from dripping onto the motor if
there is a seal leak.
