Hydraulic connection – units dor ductless installation
The supply module allows you to connect the water supply to the water heater located in the roof section (A) and to the water
heater located in the supply module (B). In case of a device configuration with an exchanger in the roof section when placing the
Cube on the supply air module, connect the flexible pipe stubs to the connections through the inspection hatch - as shown in the
picture.
Cube units in configuration with a water heat exchanger are equipped with a three-way mixing valve. The three-way valve is
transported in the device control cabinet. The valve should be installed in accordance with the hydraulic diagram of this manual.
During assembly of the installation it is absolutely necessary to immobilize the exchanger's connector pipes (counter).
