CONDITIONING PLANTS

7.1.- AIR FILTER

The filter on return air should be cleaned or replaced periodically. This filter is absolutely necessary as it pre-
vents the clogging of the air heat exchanger of the air conditioner. There is not a fixed rule to determine the
periodicity of filter maintenance; this depends from number of running hours but also from level of air pollu-
tion where the unit works. A clogged air filter reduces the unit capacity when in "Cool" mode. In "Heat" mode
a clogged air filter in a "RC" air-conditioner produces a unit shutdown because of high pressure (HP); in a
"EH" electrical heating air-conditioner a clogged air filter produces a heating shutdown because of an internal
safety klixon. In order to reset the normal functioning, it is necessary to stop the system putting it off from the
control panel, eliminate the reason of the lack of air circulation, wait approximately 5 minutes and then restart
the system pushing the "Heat" button on the control panel.

7.2.- SEA WATER STRAINER

The sea water strainer installed on sea water pump intake requires to be checked and cleaned periodically.
This strainer is absolutely necessary as it prevents the sea water pump and circuit to be clogged by dirty par-
ticles. There is not a fixed rule to determine the periodicity of strainer maintenance; this depends from the
number of running hours and more from level of water pollution where the unit works. In "Cool" mode a
reduced or nihil water flow reduces the efficiency and eventually causes a unit shutdown (HP - high pressure
switch). In "Heat" mode a clogged water strainer reduces the unit capacity.

7.3.- ELECTRICAL COMPONENTS

All electrical parts must be kept clean and dry. We suggest to check periodically for electrical leaks, which, if
detected, must be immediately eliminated.
7.4.- WINTERIZING
When freezing temperature are expected you have to drain the cooling water which may be in the condens-
er, in the pump, in the strainer and in the connecting pipes. Therefore you should close the seacock valve;
remove the condensing unit inlet water hose (the hose from the pump to the water condense). Allow time to
drain all the water from the condenser; clean the strainer and drain completely the water in it and in the pump.
7.5.- CONDENSATE DRAIN
Check periodically that the condensate discharges into water are not clogged by dirtiness or other.
