Installation and maintenance

Installation
Locate the pump in a dry location.
If the pump is mounted vertically, the
motor shall face up.
Mark screw positions and drill pilot
holes (see drilling template page 45).
Mount the pump using stainless steel
screws taking care not to over compress
the vibration dampening rubber feet.
Reinforced, high pressure flexible
tubing is recommended.
If rigid pipe is used, a length
(225 mm/9 inches minimum) of flexible
tubing shall be installed between the
pump and the rigid pipe. This will
address noise and/or damage caused by
vibration transmitted to rigid pipe.

Use stainless steel hose clamps to secure
tubing to quick disconnect fittings and
other hose barbs in the system.
A strainer must be installed in line
before the pump intake, to prevent
debris from entering pump and inter-
fering with proper functioning
of valves.
Electrical installation
The pump must be installed according to
ISO 10133 (Small craft – Electrical
system – Extra low voltage DC installa-
tion for continuous current). Note: The
fuse must be ignition protected.
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.
If the pump is connected with separate
earth lead, this should be yellow/green
and connected to the motor base.
See the wiring table (next page) for
correct installation. Negative wire must
be black.
Choose wire size in accordance with
total wire lenght (see table next page).
The wire connections must be sealed
with a marine sealant.
Note: Before installation with
electrical control systems, check that
equipment to be used is of sufficient
rated capacity to accept amperage draw
of motor. Low voltage will cause motor
to overheat.
Maintenance
The system shall be periodically
sanitized using the following procedure:
1. Fill the tank with a solution of house-
hold bleach and potable water –
1 ml (.03 oz.) bleach/1 l (32 oz.) water).
2. Open all faucets and run until water
flowing smells of bleach.
3. Close all fauces.
4. Drain solution from tank.
