Winterising the WhisperGen
Overview
Ensure you winterise your WhisperGen
TM
if you are not going to be using
your boat and your WhisperGen
TM
in cold or freezing conditions.
If the primary system is not treated with anti-freeze and corrosion-inhibitor
then it must be completely drained. If the system is treated with anti-freeze
and corrosion-inhibitor then it can be left filled, provided it has been treated
with anti-freeze and corrosion-inhibitor for any cold temperatures expected.
ƒ
After draining primary coolant, refill the coolant system through the
header tank with pre-mixed distilled water and coolant using a marine-
grade anti-freeze and corriosion-inhibitor, following the manufacturer’s
recommendations. Follow the procedure entitled checking the coolant.
You must also disconnect and drain the fresh water supply systems to the
WhisperGen
TM
, and you must also ensure that the secondary system is
drained of all raw water. The fresh water is normally plumbed into the
pressurised water supply to a fresh water connector on the WhisperGen
TM
.
Drain any water in the condensate trap and condensate drain. Do this for
all condensate drains that may be in the exhaust system.
ƒ
Unscrew the freshwater inlet on the back of the WhisperGen
TM
and
drain any water in the loop attached to the condensate drain to avoid
any pressure on the freshwater inlet from freezing expanding the pipe.
Any untreated water in the coolant pipes, fresh water flushing
hose, the condensate drains or the WhisperGen
TM
may burst pipes and
cause serious damage to the WhisperGen
TM
if any such water freezes.
The cooling system of the WhisperGen
TM
is vital to its
performance. If the coolant level is not maintained, damage may occur.
Glycol can be harmful if swallowed or inhaled. Do not store it in
open / unlabelled containers. Wash your hands thoroughly after handling it.
