This section, aimed above all for the end user, is extremely impor-
tant for the correct operation of the appliance.
Just a few operations completed scrupulously and regularly will
avoid serious damage to the components and expensive repairs
by specialist personnel.
The maintenance instructions are simple and do not require spe-
cific technical knowledge of air-conditioning.
The purpose of this chapter is to assist and guide the user and
avoid having to unnecessarily call out specialist personnel.
The maintenance operations can be summarised as follows:
- Clean the air filter.
- Check and clean the condenser coils
- Check the water-cooled condensers for fouling.
- Check and clean the drains.
- Check the drive belts.
- Check the humidification system.
- General examination of the overall operation of the appliance.
- Visual check of the condition of the pressurised containers.
Cleaning the air filter
Authorised personnel: maintenance mechanic
Checks:
The gradual fouling of the filters reduces the flow-rate of the
conditioned air, with a consequent reduction in cooling capacity.
In the direct expansion units, a reduction in the air flow-rate may
cause the activation of the low pressure switch and/or cause seri-
ous damage to the compressor.
This can be avoided by the periodical cleaning of the filters.
The frequency at which the filters must be checked exclusively
depends on the amount of dust in the environment.
In any case, the following are recommended:
- Every week check that the filters are clean
- Every two weeks clean the filters with a vacuum cleaner
- Every month wash the filters with soapy water
- Every 6 months replace the filters.
It is clear that the recommended times are purely indicative, and
in some cases it may be necessary to increase the frequency of
the checks and maintenance operations.
These operations must be carried out with the unit off and after
having made sure that the appliance is disconnected from the
power supply.
