WARNING
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
7.
After filling the system with heating medium, check the tightness of the hydraulic connections, including the
built-in vent.
