Minor model change indication
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.

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.
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 VAM500~2000J*.
▪
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. See

INFORMATION
When connected to an EKVDX, the minimum airflow during normal operation or
during the refrigerant leakage detection is always >240 m
