Product specification sheet

Application

The softening unit of the Honeywell VE300 facilitates the softe­ning of heating water. Limescale and thereby caused damages
and malfunction in hot water heating system are avoided
efficiently.

According to DIN EN 1717 the refilling combination NK300 have
to be fitted on the inlet to protect the portable water supply.

Special Features

• Intergrated water meter simplify the determination of cartridge
exchange

• Easy installation and exchange of cartridge without tools

• Constant connection with the drinking water supply in accor­dance with EN1717 by hose line or piping is possible in case
of using a NK300

Range of Application

Medium Water

Inlet pressure max. 6.0 bar

Suitable for heating systems with the following materials: steel,
copper, copper alloys and plastics.

Treated water has modified corrosive chemical parameters.
Conditioning by means of inhibitors is to be provided for separa­tely.

Installation Example

VE300 Softening unit for heating systems

Installation Guidelines

• Installation in inlet of the heating system, fasten softening unit
on the wall

o Installation into horizontal pipework

• The installation may not take place in areas or ducts where
poisonous gases or vapours may be present or where floo­ding can occur

• The installation environment should be protected against
frost and ventilated well

• The installation location has to be easily accessible

o Simplified maintenance and cleaning

• According to DIN EN 1717 first install the refilling combination
in the flow direction, then immediately thereafter install the
softening unit

• The national installation regulations must be observed during
the assembly.

• Install a shutoff facility before the softening unit in case of
installation without refillig combination
