often. Instead, a pump cycle will provide for several minutes of routine water use before pressure
diminishes and the pump starts again.
In the event a pump should fail, turn the two valves on each pump so the spare pump is
selected, and switch the selector switch to the spare pump.
Be sure to notify Northwest Explorations
that you have done this so they can repair the defect!
It is a good idea to turn off the fresh water pump breaker whenever leaving
the boat for any extended period, lest a dripping faucet or broken hose
cause the pump to run and waste your precious drinking water.
4K4: Fresh Watermaker
The boat carries a Spectra Watermaker. This
great system (which requires AC & DC power to
operate) has the following features:
!
It automatically flushes itself on a regular
basis to keep the filtration membranes
clean and in service;
!
It has automatic controls that run it for
specific periods so that you need not
worry about overfilling tanks and wasting
water;
!
It assures you that there will always be
plenty of water, however it will take
several hours to top off the tank under
normal use.
!
Note that you can use city water without
filling the tanks. Simply connect the hose
to the pressure water inlet fitting outside
the cockpit swim door and leave the hose
“on” as long as you are at the dock; this
will then go directly to the boat’s faucets
as needed, but not into the tanks.
Operation is entirely automatic.
If you are
authorized to use the watermaker,
Simply push the
AUTO/RUN button to add water to the tanks, following
these provisos:
!
Do not run the watermaker while in the harbor: You will shorten the time that the
filters can be in service;
!
Leave the watermaker on at all times so it can monitor its own operations;
!
Always leave the fresh water pump breaker on so that the purge system can
operate properly;
!
Each depression of the AUTO/RUN button will run the watermaker for one hour,
making 20 gallons of water.
