be about 1cm above the MIN mark when cool.
The heat transfer fluid (HTF) should be topped
up if below this level, to prevent a break in
circulation. Only top up with compatible HTF.
NB: Never leave the system empty of HTF.
Always replace the HTF in accordance with the
antifreeze product's lifespan. If in any doubt,
replace the HTF after 2 years.
Failure to maintain the condition of HTF may
result in frost and/or corrosion damage, and is
not covered under warranty.
When the hot water cylinder is in continuous
use, it should be drained and refilled once a
month. This recreates the air cushion in the
hot water cylinder that absorbs pressure
surges.

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.
