Technical Data; Setting Outlet Pressure - Honeywell D05FS Einbauanleitung

1. Safety Guidelines
1. Follow the installation instructions.
2. Use the appliance
• according to its intended use
• in good condition
• with due regard to safety and risk of danger.
3. Note that the appliance is exclusively for use in the appli-
cations detailed in these installation instructions. Any
other use will not be considered to comply with require-
ments and would invalidate the warranty.
4. Please take note that any assembly, commissioning,
servicing and adjustment work may only be carried out by
authorized persons.
5. Immediately rectify any malfunctions which may influence
safety.
2. Description of function
Spring loaded pressure reducing valves operate by means of
a force equalising system. The force of a diaphragm operates
against the force of an adjustment spring. If the outlet pres-
sure and therefore diaphragm force fall because water is
drawn, the then greater force of the spring causes the valve
to open. The outlet pressure then increases until the forces
between the diaphragm and the spring are equal again.
The inlet pressure has no influence in either opening or
closing of the valve. Because of this, inlet pressure fluctuation
does not influence the outlet pressure, thus providing inlet
pressure balancing.

7. Assembly
7.1. Installations Guidelines
It is necessary during installation to follow the installation
instructions, to comply with local requirements and to follow
the codes of good practice.
• Horizontal and vertical installation position possible
- In vertical installation position spring bonnet with adju-
stment knob facing upwards
• Install shutoff valves
• The installation location should be protected against frost
and be easily accessible
- Pressure gauge can be read off easily
- Simplified maintenance and cleaning
• For residential applications where maximum protection
against dirt is required, install a fine filter upstream of the
pressure reducing valve
• Provide a straight section of pipework of at least five times
the nominal valve size after the pressure reducing valve (in
accordance with DIN EN806 part 2)
7.2. Assembly instructions
When using soldering connections, do not solder the
connections together with the pressure reducing valve!
High temperature will irreparably damage important
internal working components!
1. Thoroughly flush pipework
2. Install pressure reducing valve
• Note flow direction
• Install without tension or bending stresses
3. Set outlet pressure
8. Start-up

8.1. Setting outlet pressure

Set outlet pressure min. 1 bar under inlet pressure.
1. Close shutoff valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Fit pressure gauge (optional)
4. Close shutoff valve on outlet
5. Loosen slotted screw
• Do not remove slotted screw
