3 Use and Maintenance
The pump is designed for intermittent use
only, e.g. for supplying water to a household
tap or shower.
3.1 Disinfecting
When using for the first time:
Disinfect the tank by filling it with a solution
of bleach in water (1 : 1000). Circulate this dis-
infecting mixture through the drinking water
system. Remove the solution and rinse the tank
with clean drinking water.
Calculation of the amount of common
household bleach needed to disinfect the
tank:
Use 1 millilitre of bleach for each litre tank
capacity.
Or use 0.13 ounces (oz) of bleach for each US
gallon of tank capacity.
At the beginning of the sailing season:
Disinfect the tank and prevent the growth of
algae at the same time by filling the tank with a
solution of clear vinegar in water (1 : 20). Leave
the vinegar solution in the tank for at least 24
hours, the longer the better. Remove the vin-
egar solution and rinse the tank several times
with clean tap water.

4 Winter preparation
The pressurized water system as part of the
whole drinking water system should always be
drained.
• Drain the water tank.
- Use the drain valve of the tank.
- Open a tap so that the pump will run; let
the pump continue to run for about 30
seconds after the tank is empty.
Or
- Use the pump to drain the tank, open the
tap(s) fully and let the pump run (15 min.
ON / 15 min. OFF) until the tank is empty;
let the pump continue to run for about
30 seconds after the tank is empty.
• Remove the plumbing from the inlet and
outlet connection of the pump. Switch the
pump ON, allowing it to operate until the
water is expelled. Switch off the pump.
• Disconnect the power connections to the
pump.
• Do not reconnect the plumbing. Make a
note at the tank filler as a reminder. 'Plumb-
ing is Disconnected' .
Anti-freeze
Never fill the drinking water system with anti-
freeze to protect it against freezing unless a
safe non-toxic anti-freeze for potable water is
available. Most anti-freezes are very poisonous!
Flush the drinking water system thoroughly at
the start of the summer season, if a non-toxic
anti-freeze for potable water has been used to
protect the system during the winter.
