Service tips


Ensure that the VEX unit is regularly serviced and inspected. This will ensure optimum operation. For example, failure to change filters or to carry out cleaning may increase the VEX unit's energy consumption and reduce the efficiency of the heat exchanger.

EXHAUSTO recommends users to sign a service agreement with the ventilation contractor. This will ensure that the ventilation unit can continue to meet the specified/estimated values for capacity and energy consumption - even after lengthy usage.
