Maintenance of your Heat Recovery Ventilation Unit


In order for the heat recovery ventilation system to work correctly and effectively, it is important that approved maintenance procedures are followed. Full details are given in the manual supplied. The premier maintenance activity is filter replacement. The frequency of this will depend on the following

(1)    Your geographical location
(2)    The number of people in the house
(3)     System Usage.

It is recommended that filters are changed at least once per year. Changing the filters is straightforward. The units are designed so that the filters can be easily accessed. No tools are needed and full instructions are provided in the operator manual.

See attached link on how to change filters in our ProAir 600LI Unit.

A three year parts (excluding filters) and labour guarantee is given, provided that recommended maintenance procedures are adhered to.
