Installation
The heat exchanger can be installed in the unit in any position:
A – wide tray installation, a 3° – 5° exchanger slope is recommended for condensate drainage
B – narrow tray installation, this position is allowed only if the entire weight of the exchanger does not rest on the narrow tray
C – installation on the face surface, a 3° – 5° exchanger slope is recommended for condensate drainage
Both faces of the heat exchanger must be firmly fixed and secured over the entire area so that they do not bend in the air flow.
Operating conditions
| Aluminum – REK / REC | Plastic – RSF / RSP / REP |
Operating temperatures | -40°C to +80°C | -20°C to +60°C |
Maximum recommended flow | 3 m/s | 3 m/s |
Length | 150 – 1000 mm | 100 – 600 mm |
Maximum pressure difference | 800 Pa | 800 Pa |
Anti-Fire solution (AF) | Up to 120°C | – |
We recommend using a heat exchanger with a balanced ratio between the outlet and inlet, or with a maximum imbalance of +/- 50%.

Maintenance and cleaning
If filters, approved by the ventilation unit manufacturer, are used and regularly replaced, the heat exchanger doesn‘t require special maintenance. If the heat exchanger still gets dirty, carefully remove the heat exchanger and clean it with a soft brush. It is possible to use a brush attachment for a vacuum cleaner and vacuum the dirt. Blow out the cleaned heat exchanger with air (from a vacuum cleaner) so that there is no fine dust in it. If necessary, the heat exchanger can be treated with a disinfectant or antibacterial agent, which is suitable for cleaning and disinfecting aluminum and plastic. Allow the heat exchanger to dry thoroughly before inserting it into the unit.
Important: For cleaning do not use sharp tools neither hard brushes. Beware of pressure washing. There is a risk of permanent damage to the heat exchanger!
