Winter; Troubleshooting - Bailey Approach Advance Owner's Manual

Winter

When camping in the winter, always ensure the
flue terminal remains unobstructed by snow
and ice. Extensions for roof flue terminals, and
condensate spouts for side flue terminals are
available from Alde.
Check the strength of the HTF (heat transfer
fluid ) with a hydrometer and/or refractometer.
It should measure 50% ethylene glycol
antifreeze, or -35 to 37°C.
The central heating can still be used with no
freshwater in the system. The air in the hot
water cylinder is heated but no damage can
result.
Always drain down and completely
!
empty the hot water cylinder when
there is risk of frost, unless the vehicle
is explicitly stated to be self-
winterising by the vehicle
manufacturer.
If camping in temperatures below -10°C,
consider carrying spare parts in the event
of an emergency. Alde recommends a 12v
circulation pump for the expansion tank (with
cabling), a PCB, and 4–5 litres of ready to use
antifreeze. These spare parts should be kept
well insulated and in the warmest part of the
vehicle; for example, in the wardrobe, near to
the expansion tank pipes.
If storing the vehicle for winter, ensure the flue
terminal is covered to prevent pest animals
nesting in the flue.
If using the light duty 12v circulation pump in
the expansion tank, do not leave the central
heating on over winter, even with a low desired
temperature set.
Air the vehicle over winter without
i
wearing out the light duty pump. Use
the programmable Alde control panel
to automatically heat the vehicle for
24 hours, once a week.
FITTED EQUIPMENT- The Alde Heating System

Troubleshooting

The Alde control panel will display any error
messages. See the operating and installation
instructions supplied separately.
The system is completely dead, the control
panel is blank
• Check the 20mm T3.15 amp glass fuse in
the boiler. This is located under the lid of
the black plastic service hatch, in a green
plastic fuse holder.
• Check the 12v supply to the boiler, it should
be above 12v.
• Check the 12v cable is plugged into the
boiler. Check the cable is plugged into the
Alde control panel.
The boiler will not ignite on gas
• Check the gas cylinder is full. Try a different
gas cylinder, ensuring it is propane gas.
• The system may not need to use gas
heating, if also using electric heating.
• The fluids in the boiler may already be at
operating temperature.
The boiler will not heat on 230v electric
• Check that any 230v isolator switches are
on (they will often have an LED indicator).
• Check the 230v supply to the vehicle.
• The fluids in the boiler may already be at
operating temperature.
No hot water
• Check that "hot water ignore" is not
activated on the Alde control panel.
• Check that constant pumping is not
activated on the Alde control panel.
• Check for other conflicting settings on the
