Maintenance, service and fault tracing

Winter drainage

It is extremely important to remember to winter drain
the machine before winter storage! The guarantee does
not cover damage to the titanium heat exchanger due to
freezing! Drainage is easy to perform, by unscrewing the pipe
connections on the inlet and outlet pipes. The machine is
then drained. It is a good idea to flush out the heat exchanger
in connection with winter drainage using, e.g. a garden hose
to remove any chlorine residue.
!
In the event of any uncertainty before winter
drainage, contact your dealer! An iced-up heat
exchanger due to forgotten winter drainage is
not covered by the guarantee!

Maintenance

5 Check the water supply and discharge frequently. Clean
the pool/spa filter regularly to prevent damage to the
unit.
5 The area surrounding the unit must provide good
drainage and ventilation.

5 It is a good idea to clean the heat exchanger to promote
good function and energy savings. This can easily be
done with winter drainage. Flush the heat exchanger
using e.g. a garden hose and drain thoroughly. This will
reduce the risk of chlorine deposit build up.
5 Check the power supply and cable connections regularly.
If the unit does not function as designed, shut it down
and contact the installation engineer.
5 It is a good idea to continuously check the condition
of the intake section. Clean using a sponge or the like.
Regular maintenance guarantees optimal efficiency.
5 Ahead of the winter – drain and cover!

Fault tracing

If a fault should occur you should always contact the
installation engineer who carried out the installation. If he/
she in turn considers it to be a question of a material or
manufacturing fault, he/she will contact us for inspection
and action to rectify the problem. Always state the product's
manufacturing number. Information can be gained from the
following fault tracing guide. Frequently asked questions
with answers are also presented in the section 6. Always read
through this section before contacting your dealer.
