industry class).
The unit's compliance with the above standards does not guarantee
the compliance of the installation as a whole (several other factors not relating to
the unit may be involved). As a result, the installer must observe the applicable
recommendations in order to guarantee compliance.
- The operation of the heating coil must be fan-controlled.
- Power to the electric heating elements should be cut whenever the fan motor
assembly is stopped intentionally or unintentionally.
- When the system is completely shut down, ensure that the type of control chosen
allows post ventilation of the comfort unit to ensure no serious damage is caused to
it. (recommended post ventilation of at least 2 minutes)
- Units equipped with heating elements are protected against accidental overheating
by 2 temperature limiting thermostats (Fig. 15), one with manual reset (a) and one
with automatic reset (b).
Do not reset these thermostats until the potential causes of the overheating have
been checked:
The unit must be serviced periodically between the heating and cooling seasons.
In particular, components prone to clogging (filter, condensate drain pan, coil, etc.)
must be checked.
Disconnect the electrical supply to the unit before carrying out any work. The
hydraulic circuit must also be closed.
5.1. Air filter:
The filter is crucial to the correct operation of the unit. Without it the heat exchange
coil would become clogged, the performance drop and the unit's sound level rise.
The COADIS LINE
pleated filter.
CIAT recommends regular inspections of the filter's appearance in order to define the
frequency with which it should be replaced, which varies depending on the premises
and the operating conditions (replacement at least every two years). If maintenance
is carried out more frequently, the filter can be cleaned by running a vacuum
attachment (in the opposite direction to the flow of air). The above recommendations
are for information only.
