Safety Requirements; Technical Data; Installation; Commissioning (Fig. 5) - Honeywell S245B Instructions De Montage

1. Safety Requirements

• Adjustment of pressure setting and repair opera-
tions may only be carried out by the manufac-
turer. Under no circumstances shall the safety
valve be disasembled.
• The product must not be used in a damaged
condition and must be installed according to
regulations, with special regard to safety. In-
stallation must be in accordance with these
instructions. It is essential that any faults which
may influence safety be rectified immediately.
• Safety valves of the type S245 are exclusively for
the applications listed in the specification sheet.
No other application is permissible.

3. Installation

3.1. Installation Requirement (Fig. 1)
• Safety valves for pressurised air should ideally be
positioned vertically, facing upwards in the pipe-
line or on a pressure vessel. Other installation
positions on request.
• Install the safety valve in such a way that during
venting no harm can occur to persons or objects
adjacent to the unit.
Under some circumstances it is possible that
high volumes can discharge.

• Minimum clearances must be adhered to (see
figure 1).
• There must not be any shut-off devices in the
feeding pipe. The cross section of the feeding
pipe may not be smaller than the entrance cross
section of the safety valve. The pressure drop in
the feeding pipe must not exceed 3 % of the
pressure difference between open-ing overpres-
sure and superimposed back pressure during
the greatestmass flow which is to be carried off.
3.2. Assembly (Fig. 2 - 4)
1. Visually inspect the cap, thread and plug for
damage.
- A damaged valve must not be fitted.
2. Seal the valve with hemp, sealing tape or a
copper gasket.
3. Screw the valve in tight using a suitable wrench
and avoid damaging the valve.

1. Turn the adjusting knob clockwise until it tigh-
tens.
The valve is now ready for service.
If the installation is taken out of service for a
long period, then the unit should be turned to
the venting position. This is acheived by
turning the adjusting knob 2 turns anticlock-
wise.

5. Field Maintenance

Ensure dirt does not build up around the discharge
area of the safety valve

6. Function Tests

The intervals for function checks of the safety valves
must be fixed by the operator of the installation
under consideration of the local requirements for
pressure tanks (at least once a year according to the
recommendation of the manufacturer). The facility
operator should ensure that the function tests are
carried out regularly by an authorized person.
