4.1 Mounting

Installation must be in compliance with local standards and
regulations.
District heating (DH) - In the following sections, DH refers to the
heat source which supplies the substations. A variety of energy
sources, such as oil, gas or solar power, could be used as the
primary supply to Danfoss substations. For the sake of simplicity,
DH can be taken to mean the primary supply.

Connections:

1. District heating (DH) supply

2. District heating (DH) return

3. Heating (HE) supply

4. Heating (HE) return

5. Domestic hot water (DHW)

6. Domestic cold water (DCW)

Connection sizes:
