4.0 Servicing & Maintenance
4.1
Warning: The units must be isolated from the Mains Supply before
commencing any service or maintenance work.
4.1.1
Your ComfoAir unit contains self-cleaning backward curved impellors that require no servicing.
Note: The motors have sealed for life bearings, which do not require lubrication.
Periodic cleaning of the ceiling supply and extract valves should be carried out as required, taking care not to
adjust the valves set position, as this may cause an unbalanced system, resulting in either under-ventilation
or unnecessary over-ventilation occurring.
Periodic inspection and/or replacement of filters should be carried out. Frequency greatly depends on
geographic location and urban density. The filters trap dirt in the atmosphere and act as protection for both
the system and the dwelling. The system’s airflow can be reduced if the filters are not replaced, this can affect
overall system performance. For this reason, it is important to check the filters regularly and to replace them
as often as each year
(See Sections 4.1.8, 4.1.9 and 4.2.0)
.
Periodic inspection and/or cleaning/replacement of the heat exchanger should be carried out. The filters
should help to protect the heat exchanger but over time, dirt in the atmosphere can penetrate the filters
and gain access to the heat exchanger. The system’s airflow can be reduced if the heat exchanger is not
cleaned/replaced and this can affect overall system performance. For this reason, it is important to check the
status of the heat exchanger regarding the time remaining indicated on the display
(See Sections 4.2.1, 4.2.2
and 4.2.3)
.
Please contact us for replacement filters and heat exchangers.
