5.1.1 Enthalpy Heat exchanger Maintenance
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.
