Air Change will be pleased to provide advice on special service requirements for

particular installations.

IMPORTANT: Return and Fresh air filters must be changed/cleaned

regularly to ensure airflow is unrestricted. Heat exchanger warranty may be

voided if filters are not cleaned according to maintenance schedule and if

proper filtration standards are not adhered to.

NOTE: Air Change can provide a heat exchanger replacement service on

request.

WARNING: Switch off unit before attempting to remove parts for

cleaning.

IMPORTANT: DO NOT WASH THE ENTHALPY HEAT EXCHANGER

• The Enthalpy Heat exchanger has a brown paper-based enthalpy exchange

media between the plates which can be vacuumed or brushed gently.

IMPORTANT: DO NOT ATTEMPT TO CHANGE THE LENGTH OF THE

HEAT EXCHANGER BY REMOVING END PLATES AND PLASTIC PLATES.

This can mean that the media between the plates is dislodged from its

position and therefore will cause lack of performance through increased

pressure drop through the heat exchanger or damage to the Sensible

media. Any tampering with the heat exchanger may invalidate our warranty

and Air-Change will not be held responsible for lack of performance or

pressure drop.

If the heat exchanger is the incorrect length, please return to Air-change for

a replacement unit.
