PRE-SEASON MAINTENANCE
▶
Disconnect the unit from the power supply using the
switch on the electrical panel on board the appliance.
▶
If the protective cover is present, remove it and check
that it has not been damaged, clean it thoroughly with
a mild detergent and store it in a place where it is not
directly exposed to the weathering.
▶
Remove the appliance cap.
▶
If necessary, clean the base.
▶
Check the evaporating panels and, if necessary, clean
them of any sludge deposits by washing them with
water and of small limescale deposits by shaking
them. If there are significant deposits, the panel must
be replaced.
▶
Check that the water ducts are clean and that there are
no obstructions in the water distributor, at the top of
the unit. Remove any debris from the water recircula-
tion pump's float.
▶
Supply the power to the appliance via the switch on
the electrical panel on board.
▶
Open the water supply.

Activate, through the control system provided, the
operation in cooling mode and observe that the drain
valve closes and the tank is filled with water until the
point where the loading valve will cease to supply wa-
ter.
▶
Check that the water is distributed evenly over all the
evaporating panels.
▶
Check the operation of the drain valve, making sure
that it opens within 5 minutes from appliance switch
off.
▶
Check for water leaks from tanks and supply pipes.
▶
Check cables conditions.

Replace the cover and make sure that it is securely fas-
tened with the appropriate bolts.
