4.3 About the heat reclaim ventilation
unit
The heat reclaim ventilation unit is intended for indoor installation.
NOTICE
ALWAYS use the air filter. If the air filter is NOT used, the
heat exchange elements can get clogged, possibly causing
poor performance and subsequent failure.
Operation range
Outdoor air + return
air
Temperature –10°C DB~46°C DB
Relative Humidity ≤80%

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 have to be taken to prevent condensation. Example:
install a pre-heater to heat up the 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.
4.4 Combining units and options
4.4.1 Possible options for the heat reclaim
ventilation unit
Adapter printed circuit board
Options BRP4A50A and KRP2A51.
At temperatures below –10°C, it is mandatory to use an electrical
heater. This is connected with option PCB BRP4A50A.
CAUTION
If an electrical heater is installed, use nonflammable duct.
For safety, be sure to keep 2 m or more between the
heater and the heat reclaim ventilation unit.
If you install any of these options on the VAM650, you have to
prepare the mounting plate (EKMP65VAM).
If you install any of these options on the VAM1500 or VAM2000, you
have to prepare the mounting plate (EKMPVAM).
If you install KRP2A51, you have to prepare the fixing box
(KRP1BA101).
Filter
When. This option might be mandatory. Check the local legislation.
It is recommended in places with poor outside air quality.
Where. Install the filter behind the heat exchange element either at
the side of air supply or air exhaust. Keep the standard filter in place.
ONLY replace the standard filter when an option filter is put in front
of and behind the heat exchange element.
How. For installation instructions, see the installation manual of the
filter kit.
Pressure drop over the filter. See the databook for pressure drop
curves for each capacity class of unit and each class of filter.

Plenum (EKPLEN200)
When. The plenum is an option for VAM2000. This
option can be used to ease the installation of the heat reclaim
ventilation unit.
