Technical Data; Installations Guidelines - Honeywell D15S Instrucciones De Montaje

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.
3. Application
Medium Drinking water, compressed air
ISO 8573-1 class 2 in consideration of
valid standards (e.g. EN 12502)
Inlet pressure max. 16 bar
Outlet pressure

7. Assembly

7.1. Installations Guidelines

• Install in horizontal pipework with spring bonnet directed
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
• Install downstream of the filter or strainer
- This position ensures optimum protection for the pres-
sure reducing valve against dirt
• 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
1. Thoroughly flush pipework
2. Install pressure reducing valve
• Note flow direction
• Install without tension or bending stresses
3. Seal pressure gauge
