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 37).
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 interfering with
proper functioning of valves.
Electrical installation
The pump must be installed according to
SS-EN ISO 10133 (Small craft – Electri-
cal system – Extra low voltage DC instal-
lation 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 installa-
tion. Negative wire must be black.Choose
wire size in accordance with total wire
lenght.
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.
5. Refill tank with potable water.
6. Open all faucets and run until
bleach has been purged.
