WATER PUMP
The separate plug-in pump assembly
consists of a Crystal Maxi pump, hose and
plug. The plug provides connection of both
water supply to the caravan and 12V dc
electric power to the pump. A dust cover is
fitted to the connecting dual hose to prevent
contaminants falling into the water container.
The Crystal Maxi pump is a completely
sealed unit designed for intermittent use. It is
NOT self-priming and therefore to ensure
proper performance, the pump MUST
ALWAYS be fully submersed in water
BEFORE plugging into the wall socket.
Maintenance
Poor pump performance may be an
indication that the filter has become blocked
by debris. The filter is easily removed for
inspection and cleaning:
• Remove circlip and unscrew filter from
pump.
• Pull two halves of filter apart to expose the
strainer mesh.
• Remove any debris and replace strainer
mesh in position.
• Ensure the rubber seal is correctly seated in
the groove on the outlet side of the strainer
before pushing the two halves firmly
together.
• Attach to the pump and replace the circlip.
• See arrow on pump housing for flow
direction.
Care of your Submersible Pump
Care should be taken to ensure that the
pump is not allowed to run dry for
appreciable periods. Whilst the design will
allow some dry running, such as when the
tank requires refilling, the pump life will be
appreciably lengthened if care is taken to
minimise dry running.
Aquaflow Caravan Filler
There is a special filler fitted for use with the
Submersible Pump which not only provides a
recessed, locking filler cap for water input,
but also a polarised power take-off point
complete with input plug. This is part of the
original equipment for Delta models only.
The Water System for Delta Models
A submersible pump is used for pumping
water from an external container into the
inboard tank of the caravan.
To Operate The System
First ensure that the drain tap on the inboard
tank is closed. Place the pump inside your
filled container. Place the hose into the filler
cap on the side of the caravan. Plug in the
12 volt plug into the socket on the filler cap.
When the water container is empty unplug
the 12 volt -do not allow the pump to run dry.
