3. Recommended installation
Before the installation, all pipe work must be blown or flushed through to prevent any foreign material such
as pieces of wood, stone etc. from entering the valve.
Regulating valves are normally fitted with the valve cover upwards. It is recommended that shut-off valves be
fitted on both sides plus a dirt trap on the inlet side. Depending on the installation situation, a mounting
adapter may also be required. If the HAWIDO 1400 is used as a relief valve, the shutoff gate valve on the
outlet side can be omitted. Before commissioning, a check should be made that no coarse foreign bodies
can penetrate into the HAWIDO.
For other types of installation, please contact us for advice.
