10 About the heat reclaim
ventilation unit
The heat reclaim ventilation unit is intended for indoor installation.
NOTICE
ALWAYS use the air filters. If the air filters are NOT used,
the heat exchange elements can get clogged, possibly
causing poor performance and subsequent failure.

Relative humidity
It is possible that, due to condensation, the paper heat exchanger
deteriorates when the unit operates in conditions with high indoor
humidity combined with low outdoor temperature. If such combined
conditions occur for an extended period of time, the necessary
precautions must be taken to prevent condensation. Example: install
a preheater to heat up outdoor air.
When the heat reclaim ventilation unit is installed upside down, the
minimum allowed outdoor air temperature is 5°C. If this cannot be
guaranteed, you MUST install a heater to heat up the outdoor air to
5°C.

About the EKVDX option

The EKVDX option is an airconditioning unit for the pretreatment of
incoming supply air from a VAM heat reclaim ventilation unit. For
comfort temperature control, it is still required to install a normal
indoor unit.
EKVDX units are available:
▪ for models VAM500~2000J8.
▪ with refrigerants R32 or R410A.
In case an EKVDX is installed, after setting the field settings on the
EKVDX, make sure to set the appropriate field settings on the VAM.
