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. Check that the
machine is really 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.
Maintenance
Clean the pool/spa filter regularly to ensure sufficient
;
circulation.
Check that the area surrounding the unit provides good
;
drainage and ventilation.
It is a good idea to clean the heat exchanger to promote
;
good function and energy savings. This is easily 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.
Check the power supply and cable connections regularly.
;
If the unit does not function as designed, shut it down
and contact the installation engineer.
Check that the evaporator is clean. Use a brush and
;
vacuum to remove any dust or leaves. Don’t use a high
pressure jet! Regular cleaning will guarantee maximum
efficiency.
Clean the surface using a sponge or the like. To minimize
;
ageing of the surface, it’s recommended to apply wax at
least once every year.
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.
