Clean the filter periodically by removing the
white filter insert using the following proce-
dure:
1. Remove the end of the filter (at the back
of the pump).
2. Pull out the white insert.
3. Clean the insert with bleach and a brush.
4. Put the insert back and screw back the end
of the filter taking notice of the rubber
gasket.
Pressure adjustment of the accumulator tank:
1. Shut off the pumps.
2. Open a faucet to relieve the system
pressure.
3. Adjust precharge pressure in tank with a
ordinary tire gauge and tire pump at valve
in end of the tank
4. Start up the system according to start-up
procedure.
Start-up procedure
After pump installation, using the following
procedure can start the system:
• Fill water tank with potable water.
• Open one tap.
• Turn on the pump.
• Close tap once water begins flowing.
• Open each additional tap until all air has
been purged from the system.
• P ump will shut off after taps are closed
and pressure builds to the set point of the
pressure switch
Self-priming
Pump unit is self-priming up to 2.5 m/8.2 feet.
Intake lines must be airtight to ensure self-
priming.
Dry running
Pump unit will not be damaged by shorter pe-
riod of dry running. It will, however, unneces-
sary reduce your battery power.
Accumulator tank
The accumulator tank incorporated in the sys-
tem is there to provide a smooth water flow
and reduce on/off cycling of the pumps. Less
wear and longer service life for the pump are
achieved. The accumulator tank is precharged
at 0.8 bar. The pressure should be checked
from time to time. (Look under maintenance)
Original instructions
Caution
Do not use the pump unit for any other li-
quids then fresh-water and seawater.
Do not overpressure tank. Pressure over 12
bar (170 psi) may rupture tank and cause
personal injury.
Temperature
Max liquid temperature: +50°C/+120°F
Max ambient temperature: +60°C/+140°F
Winterizing
If water is not drained from the system during
freezing temperatures, damage is likely to be
sustained in the plumbing and in the pump.
To prevent damage follow the instructions
beneath:
1. Drain water storage tank.
2. Open all taps.
3. Run pump until remaining water is
expelled.
4. Disconnect inlet and outlet tubes
5. Run pump briefly to confirm that
water has been expelled.
6. Taps shall remain open and pump
fittings shall remain disconnected
until temperatures are above freezing.
Never start a frozen pump. Even if it is drai-
ned it might contain a small amount of frozen
water that locks the rotor.
Service instructions
(see page 31-33)
Change of Switch (pos A)
