STYLE 2000 MONO-MIX
The Mono-Mix (Fig. 5) is a single lever
controlled mixer unit which is mounted through
a table or work surface. Hot and cold water are
supplied independently to the inlet of the unit,
under the work surface and mixed water
delivered through a single outlet pipe to the tap
or shower. When the control lever is rotated
(90° from OFF to fully ‘ON’) a microswitch
operates the water pump to pressurise the
water system. The degree of lever movement,
in an anti-clockwise direction, determines the
temperature of the water. The volume of water
is controlled by the tap or shower head being
used.
THE ‘CARINO’ SHOWER UNIT
The shower (fig. 6) is a chromed handset and
flexible pipe on a wall mounted, chromed
tubular, height adjustable, fitting. Adjustment is
by pressing the button on the end of the sliding
shower carrier. The shower is removable for
hand held operation.
PRESSURISED WATER SYSTEM
PUMP
Fresh water is supplied to the motorhome from
an external water container by the Carver
Crystal Filter System which consists of a
socket located near the battery box, on the
offside of your motorhome and a separate
plug-in pump assembly, The socket is
protected by a hinged lid which should be kept
shut when the pump is not connected. The lid
is easily opened by gripping the lower edge
and pulling outwards. The separate plug-in
pump assembly consists of a submersible
pump, hose and plug. The plug provides
connection to both water supply to the
motorhome and 12 volt DC electric power to
the pump. A dust cover is fitted to the
connecting dual hose to prevent contaminants
falling into the water container.
PRESSURE SWITCH
In most modern motorhomes the water system
is pressurised. When a tap is closed pressure
of water builds up in the system. At a
predetermined level, the pressure will operate
a “pressure switch” which in turn will stop the
pump running. Opening a tap will reduce the
pressure and the pump will start running. At
normal flow rates the submersible pump
should operate continuously - but at low rates
the pressure switch will cycle on and off to
maintain back pressure in the system, an
adjustment to the switch’s diaphragm
sensitivity is required. This also may be
required, usually because the power supply
voltage has varied by more than ± 0.5 volts.
The possible causes are:
1. Battery drainage through normal use.
2. Setting the switch when on mains electric
supply (typically 230 volts) then using a 12
volt battery.
3. Setting the switch when on 12 volt battery
then using mains electric supply (230
volts).
TO ADJUST THE PRESSURE SWITCH:
1. With the system properly primed, close all
taps and showers.
2. Leave the pump run switch (located on the
12 volt distribution panel) turned on.
3. Tighten the adjusting screw clockwise. The
pump should now be running.
4. Partly open one cold tap to allow water to
flow at about 1 pint in 15 seconds.
5. Slowly loosen the adjusting screw, by
turning anti-clockwise, until you can hear
the micro-switch start to click. The
diaphragm will then be properly adjusted.
NOTES
1. Never allow the pump to run DRY.
Always ensure that the pump is
submerged in the water or the life of the
pump will be reduced.
2. Do not allow the pump, the water container
or the water system to freeze in the winter.
Always drain the system at the end of the
season.
3. Clean the water system at the start and the
