HYDRAULIC CONNECTION FOR INDOOR UNIT

ENGLISH

Connection to the Domestic hot water system

The hydraulic connection has to be installed in accordance with the national and local regulations
for connecting buffer tanks for DHW to enable the water flow in full force. To prevent water
leakage, install a drain through the floor below the level of the device. The following picture
shows the correct hydraulic connection of the device.

Water Piping

Connect the hot water pipe 

①

, the cold water supply 

②

and optionally the re-circulation pipe 

③

as shown below. If a re-circulation pipe is not used, close it with a ¾’’ cap.

Use a counter wrench to tighten the connections firmly.
