2. Description of function
The heater water treatment unit (VE300) installed directly
below the refilling combination (NK300) uses the ionic
exchange principle to soften water, replacing alkaline earths
such as calcium and magnesium with sodium ions.
Depending on the regional water hardness, the heater water
treatment unit is set to partially soften (<8°dH) or completely
soften (<0.11°dH) the water.
Complete demineralisation will completely remove the
mineral deposits in the water!
For complete demineralisation, the dilution must be set to 0!
3. Application
Medium Water
Inlet pressure max. 6,0 bar
Suitable for heating systems with the following mate-
rials: Steel, copper, copper alloys and plastics (for
softening) and aluminium, aluminium alloys, steel,
copper, copper alloys and plastic (for complete demine-
ralisation).
Treated water has modified corrosive chemical para-
meters. Conditioning by means of inhibitors is to be
provided for separately.

7.1. Installations Guidelines
• Installation in the inlet to the heating system, fasten the
heater water treatment unit (VE300) to the wall
• Installation into horizontal pipeline
• The installation may not take place in areas or ducts where
poisonous gases or vapours may be present or where floo-
ding can occur
• The installation environment should be protected against
frost and ventilated well
• The installation location has to be easily accessible
- Simplified maintenance and cleaning
• Acc. to DIN EN 1717 in direction of flow, first install the
refilling combination (NK300) and directly after it, the
heater water treatment unit (VE300)
• The national installation regulations must be observed
during the assembly.
• When installing a refilling combination (NK300) above the
heater water treatment unit (VE300), provide a shut-off
device
7.2. Assembly instructions
The national installation regulations apply during the
assembly.
Provide shut-off device to safeguard cartridge
exchange
1. Thoroughly flush pipework
2. Install heater water treatment unit (VE300) and secure in
place with the wall bracket
• Install in horizontal pipeline
• Note flow direction (indicated by arrow)
• Install without tension or bending stresses
3. Set installation height min. 55cm from the ground to
ensure reliable cartridge exchange.
4. Screw the cartridge (see accessories) into the heater
water treatment unit (VE300) and tighten by hand
