Danfoss DWH 200, Installation Manual

Page: 14 / 28

3.2.2 Water quality
The indirect heating of the water for consumption is an advantage, which makes Danfoss DWH suitable in areas with high calcium levels
in the water. In installations where the water comes from a well the water should be checked to ensure that it cannot cause damage to
the hot water installation.
• Stainless steel tanks and pipes should not be exposed to water with high chloride levels.
N
With very poor water quality, a water filter must be installed in the in-
stallation. A water analysis will provide indication of any necessary re-
medial actions.

If Danfoss DWH is installed in combination with DHP-L Opti or DHP-L Opti Pro/DHP-L Opti Pro+, the sensors (NTCtype) in the heaters
must be connected to the following terminal blocks:

If Danfoss DWH Varius Design is installed in combination with DHP-L Varius Pro+, the sensors (PT 1000 type) in the heaters must be
