In the event that the pressure of
approximately 0.7 bar is not reached (for
example if the system is being purged of air
with the taps open) the pump will continue
to run until the taps are closed.
After a purge cycle the tap may have to be
used two or three times in order for full
pressure to be attained. In order to give the
system time to purge the dry run feature is
inhibited for a period of 3minutes from the
initial switch on.
Assuming that the system is now full of
water, the tap closed and the pump has
stopped, the pressure in the system is likely
to be in the range of 0.9 – 1.2 bar (target
pressure) dependent on voltage and the
example of pump used.
Normal Use
If a tap is opened the pump will start to run
when the pressure in the system drops to
the target pressure less 0.1 bar is again
reached the pump will continue for
approximately 7 seconds then stop.
Voltage Reduction
In the event of a reduction of voltage the
target pressure and all associated switch
on/off pressures are adjusted downwards. If
the values are reduced too much this does
not matter as the next time the tap is closed
the pump will push them back up.
Dry-run Protection
Finally in the event that the pump is running
but pressure is below 0.25 bar the unit
switches off the pump and locks out in order
to protect the pump knowing that the water
supply has run out. After the water
container has been refilled the power should
be removed from the system for a period of
approximately 3 seconds then re-connected.
The unit will then operate normally.
All pressures quoted above are for example
only and in practice may vary slightly.
ON LASER MODELS THE WATER CAN BE
SUPPLIED FROM THE UNDERSLUNG
WHALE TANK (SEE SEPARATE
INSTRUCTIONS).
ULTRAFLOW OUTDOOR SHOWER
The outdoor shower connects directly to the
Ultraflow Filter Housing beside the pump
socket. The supplied connector with quick
fittings ensures an easy installation.
Please note, that the shower has no
electrical connections and works only in a
pressurised system.
ULTRAFLOW WATERLINE
The Ultraflow Waterline is a 15 metre “food
quality” hosepipe. It comes complete with
fittings and a special pressure-reducing
adaptor, which allows caravanners to
connect their Ultraflow caravan water
system direct to a mains water supply with
modification.
ULTRAFLOW REPLACEMENT
FILTER
The Ultraflow Filter Cartridge is a high
quality water filter, which removes
unpleasant tastes and odours from the
caravan’s stored water. For the occasional
caravanner, the cartridge should be replaced
at the start of each season. For the regular
caravanner we recommend to replace the
filter after 35 days of use.
