3. Recommended installation
Before the installation of the fitting, the pipe lines must be carefully 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 an gate valve at the outlet.
During maintenance the valve must be taken out of service. A by-pass installation should be considered here
in order to ensure the supply.
Depending on the system, the installation of a pressure relief valve type 1400 in the outlet after the pressure
reducing valve should be considered.
Before the installation, check that no coarse foreign objects can penetrate into the HAWIDO.
Please contact us for other types of installation.
