Plumbing
Use hose that does not kink when bent,
and also with sufficient wall thickness
preventing collapse when used on suction
side, eg. reinforced hoses.
Hoses should be routed so that some
water will remain in pump body to wet
impeller for easy start up.
Use a strainer at intake hose to prevent
from trash and solids entering the pump.
In order to ensure good priming always
keep connections airtight.
Electrical installation
The pump must be installed according
to ISO 10133 (Small craft - Electrical
system - Extra low voltage DC installation
for continuous current). Note: The fuse
must be ignition protected.
The motor is equipped with built in ther-
mal protection to prevent the motor from
overheating. The protection is automati-
cally restored when the motor is cooled.
If the pump is connected with separate
earth lead, this should be yellow/green
and connected to the motor base.
See the wiring table for correct installation.
Choose wire size in accordance with total
wire length (see table beside).
The pump should be operated by a Polarity
Reversing switch, through an over current
protected distribution panel fitted with a
25 Amp/12V or 15 Amp/24V breaker
or fuse.
The wire connections must be sealed.
Note: Before installation with electrical
control systems, check that equipment
to be used is of sufficient rated capacity
to accept ampere draw of motor.

*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.
Operation
The Ultra Ballast pump is reversible so
it can both add liquid ballast and then
pump it overboard when needed. As an
alternative you may pump liquid ballast
from one tank to another and reversed.
At need for adding ballast you flip the
switch to fill position and watch for indica-
tors that tank is full, then switch pump off.
To reduce ballast, flip switch to drain
position. The pump will reverse to pump
ballast back over board. Watch indicator
for an empty tank and switch pump off.
The same operation is used for ballast
transfer between two tanks.
