3. Recommended installation
Before the installation of the fitting, the pipe lines must be carefully blown or flushed through to prevent any
foreign material, such as pieces of wood, stones etc., from entering the regulating valve.
The HAWIDO must be installed horizontally with the valve cover upwards (other models available on
request). We recommend that a gate valve and a dirt trap be fitted in front of the valve, as well as the
mounting of a gate valve at the outlet.
During maintenance, the valve must be decommissioned. A by-pass installation should be considered here
in order to ensure the supply.
Before the installation, check that no coarse foreign objects can penetrate into the HAWIDO.
Please contact us for other types of installation.
Installation note:
The water will be drained out of the valve chamber when the solenoid valve is switched (5). This water must
be led to the sewage system in accordance with local situation.
