Water exchanger
It is very important for the exchanger to be able to
provide the maximum thermal exchange. Therefore,
it is essential for the inner surfaces to be clean of
dirt and incrustations.
Periodically check the difference between the
temperature of the supply water and the
condensation temperature. If the difference is
greater than 8 °C – 10 ° C it is advisable to clean
the exchanger.
The clearing must be effected:
With circulation opposite to the usual one
With a speed at least 1,5 times higher than the
nominal one
With an appropriate product moderately acid
(95% water + 5% phosphoric acid
After the cleaning rince with water to inhibe the
detergent rests.
Water filter
Check that no impurities prevent the correct
passage of water.
Flow switch
check operation
remove incrustations from the blade
Pressure relief valve
The pressure relief valve must be replaced:
if it has intervened
if there is oxidation
based on the date of manufacture, in
compliance with local regulations.
Circulation pumps
Check:
there are no leaks
status of the bearings (anomalies are indicated
by abnormal noises and vibrations)
the terminal protection covers are closed and
the cable glands are properly positioned
Fans
Check:
the fans and the relative protection gridsare well
fixed
the fan bearings (evident by noise and
anomalous vibrations)
the terminal protection covers are closed and
the cable holders are properly positioned
Structure
Wash with warm water.
Do not use chemicals.
Check the state of the structure and the presence
of oxidation.
Paint if necessary.
Insulations
Check the condition of the insulations: if necessary
apply glue and renew the seals.
Air coil
Contact with the exchanger fins can cause cuts: wear
protective gloves to perform the above described
operations.
It is extremely important that the battery gives the
maximum thermal exchange; therefore, its surface
must be cleaned from dust and deposits.
Remove all impurities from the surface
Vacum cleaner can be used to suck impurities from
the air input side.
Verify that the aluminum fins are not bent or
damaged, in the event of damages contact the
authorized assistance center and get the fins
straightened in order to restore the initial condition
for an optimal air flow.
Wash with lukewarm water to complete the cleaning.
Do not use chemical substances.
In case of highly aggressive environments (industrial,
coastal areas, etc.), cleaning must be carried out on a
monthly basis
