3 About the units and options

3.1 About the heat reclaim ventilation unit

The heat reclaim ventilation unit is intended for indoor installation.
Models 650~1000
Models 1500+2000
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.
Operation range
Outdoor air + room air Operation range
Unit location
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.
Temperature –10°CDB~46°CDB Relative humidity ≤80%
Temperature 0°CDB~40°CDB Relative humidity ≤80%

4 Preparation

4.1 Preparing the installation site

Do NOT install a heat reclaim ventilation unit or air suction/discharge grille in the following places:
▪ Places, such as machinery plants and chemical plants, where
noxious gases or corrosive components of materials such as acid, alkali, organic solvent and paint are present.
▪ Places, such as bathrooms, subject to moisture. Moisture can
cause electric shock, electric leakage and other failures.
▪ Places subject to high temperature or direct flames.
▪ Places subject to much soot. Soot clings to air filter and heat
exchange elements, disabling them.

NOTICE
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.
▪ Keep in mind that the ceiling hooks must be rotated 180° when
the heat reclaim ventilation unit is installed upside down (see the figure).
INFORMATION
When the unit is installed vertically, the installer must provide a support under the unit to distribute the weight of the unit between the support and the installation bolts in the wall.
NOTICE
When the heat reclaim ventilation unit is installed vertically in low outdoor temperature conditions, dewing or freezing may occur. If such operating conditions are to be expected, take the appropriate precautions, e.g. install an electrical heater.
Installation tips:
▪ Installing the unit upside down allows for common use of the
inspection hole, thus reducing the required maintenance space. For example, if 2 units are installed closely together, only 1 inspection hole is required for maintaining or replacing filters, heat exchange elements,…

▪ The minimum bend radius for flexible ducts is as follows:
(Øduct/2)×1.5
▪ To prevent air leakage, wind aluminium tape around the section
where the duct joints and the ducts are connected.
▪ Install the opening of the supply air as far as possible from the
opening of the room air.
▪ Use ducts with a diameter that fits the unit model. See the data
book.
▪ Install the two outdoor ducts with a downward slope (minimum
1:50) to prevent entry of rain water. Also provide insulation for both ducts, to prevent dew formation. (Insulation material: 25mm thick glass wool)
▪ If the temperature and humidity levels inside the ceiling are always
high, install ventilation inside the ceiling.
