1. Disconnect the curtain power supply before connecting the water system.
2. The connection should be made without stress. It is recommended to use flexible ducts supplying the
heating medium.
3. Water supply should be connected to the connector marked with the symbol ↓ IN.
4. The installation with the heating medium must be protected against the increase of the heating medium
pressure above the permissible value (1.6 MPa).
5. Before starting the device, check the correct connection of the heating medium and the system for
leaks.
6. During assembly of the installation it is absolutely necessary to immobilize the exchanger's connector
pipes (counter)
7. After filling the system with heating medium, check the tightness of the hydraulic connections, including
the built-in vent.
1. It is recommended to use bleeding/air release valves at the highest point of the installation. When
installing the device vertically, bleeding should be done using the built-in valve (Fig. 17.2), while protecting
the remaining elements of the device against water damage/flooding.
2. In the event that the water from the device is drained for a longer period of time, the exchanger tubes
should be blown and dried with compressed air.
3. Installation should be carried out in such a way that in the event of a failure it is possible to dismantle
the device (use of flexible hoses is recommended). For this purpose, use shut-off valves next to the
device. (Fig. 17.3)
