Dampers
Dampers and their mechanism can be cleaned first with compressed air, then with a slightly alkaline de-
tergent. Particular attention should be paid to the levers of the actuation system.
Seals should be checked at regular intervals.
Also check if there is good rotation of the fins and the lubrication of the mechanisms. If necessary use
molybdenum disulphide oil in a spray as it is possible to direct the flow where it is needed.
Exchange coils
The coils must be cleaned at the slightest sign of contamination.
The coil should be cleaned and washed gently to avoid damaging the fins.
For cleaning using a
mild detergent
suitable for the purpose. Do not use alkaline, acidic or chlorine-based
solutions.
THE coils can be washed with a slightly pressurised water jet (max. 1.5 bar). The jet must NOT contain
chemicals or microorganisms. Moreover the water must be sprayed in the opposite direction to the air
flow and parallel to the fins.
For the direct expansion system, all the coolant in the batteries must be collected in the receiver before
washing the coil with water. This makes it possible to avoid the increase of the pressure and damage to
various parts of the pipe, keeping the airflow clean.
Alternatively, it is possible to remove the batteries from the unit during cleaning. Avoid exposing them to
the light and keep them in the dark.
For the cleaning of the injection tubes, you can access the distributor by removing the protective metal
foil. Clean it with a soft brush and water, or if it is very dirty use a disinfectant diluted in water.
Fans
The fans can be cleaned with compressed air or by brushing them with soap and water or with a mild
detergent. Finish cleaning by rotating the impeller by hand to check there are no abnormal noises.
Vents
Periodically check that there are no new sources of contamination near the air intake. Each component
must be checked periodically for the presence of contamination, damage and corrosion. The seal can be
protected with glycerine-based lubricants or replaced with a new one, if worn.
