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 flex-
ible 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.

The pump must be installed according to
2.1 A
ISO 10133 (Small craft – Electrical sys-
2.5 A

tem – Extra low voltage DC installation for
3.1 A
continuous current). Note: The fuse must

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.
24 V
If the pump is connected with separate

earth lead, this should be yellow/green

correct installation. Negative wire must
be black.
Choose wire size in accordance with
8 A
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.
