2. Tighten the adjusting screw clockwise until
the pump comes on. (For integral socket based
pressure switches, first loosen the pressure
switch locknut in an anti-clockwise direction).
3. Open any tap until you have a smooth flow
of water, then close the tap. You should hear
the pump running and the pump running light,
if fitted, will be on.
4. Return to the pressure switch and turn the
pressure switch adjustment screw slow anti-
clockwise until the pump has stopped. Turn
the screw a further half turn (180 degrees)
anti-clockwise.
5. Check for correct operation by opening and
closing all taps individually. The pump should
turn on when the cold tap is opened and switch
off immediately when the cold tap is closed.
NB. There will normally be some pulsations at
lower flows.
The hot side may take a few seconds to react
(both on and off) due to cushioning effect in the
water heater.
For integral socket based pressure switches,
carefully tighten the locknut until it is right
keeping the adjustment screw in position.
If setting of the pressure switch is still not
correct you may experience:
> Pump running continuously, even with tap
closed. If undiscovered, could result in pump
failure and flat battery. Most likely causes
are that present voltage is significantly
lower when last adjusted, or water container
is empty.
Solution: Re-adjust switch or refill container.
> Pump does not run at all. If not due to a
blown fuse or faulty connections, then most
likely cause is excessive running (see above)
Solution: Replace pump and re-adjust switch.
> Pump runs intermittently ON, OFF etc. Seen
as pulsing flow from tap, or as inability
to set constant water temperature, water
goes hot, cold, hot, cold instead of constant
warm. Most likely cause is that present
voltage is higher than when last adjusted.
Solution: Re-adjust pressure switch if problem
persists add a Whale Surge Damper (WS7205.)
> Pump runs very noisily but does not pump
water. Likely to occur after water container
has been refilled. Pump is air-locked and is
fighting to get air out of and water in.
Solution: Unplug from the socket, allowing
pump to flood, and reconnect by plugging in
again. The correct sequence when refilling the
container is to unplug put pump into container,
then reconnect.
If after following these procedures the system
continues to pulse when all taps are closed
there may be a leak in the system.
To
Check the Water Level
(Both Autograph and Advance)
— Press the down arrow until you
see the fresh water icon; The level
is shown as a percentage.
—Press the down arrow until you
see the waste water icon; The
level is shown as a percentage.
Draining and winterising the
Fresh water systems
Motorhomes are often used all year round
but when they are not in use, even for short
periods they should be drained down. One night
in freezing temperatures is all that is required
for expensive, permanent damage to occur to
water system components.
Follow this procedure to prevent any damage:
1. Open all taps; lift the mixer tap levers in
the central position to allow both the hot
and cold water to drain.
2. Remove the shower head; unscrew by hand
then shake out and store in a dry place.
3. Open the drain valve (to the side of the
onboard tank in Advance models. To the
side of the boiler on Autograph models).
Then turn on the pump to drain the system.
