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 heat transfer fluid
(HTF) with a hydrometer and/or refractometer.
It should measure 50% ethylene glycol
antifreeze, or -35-37°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.

! WARNING: 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.
