3 Installation
3.1 General Warning
•Do not install the product unless the safety instructions have been read
and understood.
•The valve is designed for pulse operation. Do not energise the valve
continuously as it can cause oscillation (chattering) of the diaphragm
leading to product failure due to the large amount of air consumed
causing insufficient air supply on the inlet side. In addition, continuous
energisation may lead to excessive temperature rise. See 2.1 for
maximum operating frequency and duty cycle limitations.
•Customer shall ensure that the sudden pulse of air released by the
valve when operated does not generate an ignition source within the
system.
•See 3.3 regarding internal earthing and external bonding.
•Use clean air filtered to 5 µm or less. Filtration to be installed upstream
near to the valve. Caution
•Use steel tubing for the inlet and outlet piping.
•Do not rely on the valve piping ports to support the piping. Ensure that
the piping is independently supported so that pulling, pressing,
bending or other forces are not applied to the valve body.
•For details regarding pipe sizes, refer to the standard JSXF Series
catalogue.
•Ensure that the air supply is sufficient to meet the high flow demand of
the valve when operated. If the inlet is restricted or the supply tank
capacity is low, then the main valve may oscillate (chatter) due to
pressure drop or insufficient supply.
3.2 Environment Warning
•Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
•The product must be protected from UV light.
•Do not install in a location subject to vibration or impact.
•Do not mount in a location exposed to radiant heat that would result in
temperatures in excess of the product’s specifications.
•The valves are certified to Ex category 3GD (Zones 2, 22).
•Do not mount in areas subject to electrostatic charging mechanisms.
•Do not install in locations subject to the accumulation of water.
Exposure to natural weather is not permitted.
•Products compliant with IP65 enclosures are protected against dust
and water, however, these products cannot be used in water.
•Products compliant with IP65 enclosures satisfy the specifications by
mounting each product properly. Be sure to read the Specific Product
Precautions for each product.
3.3 Earthing and Bonding Warning
3.3.1 Internal earthing
An internal earth connection is not required for this 24 VDC, 2-wire
product. The earth connection facility of the DIN connector has no
function. Only pins 1 and 2 (+/-) of the connector shall be wired, see 3.7
for connection diagram. Warning
3.3.2 External bonding
•An external bonding facility is mandatory for this product. A ring
terminal is provided (included in product packaging) for this purpose to
be installed using the marked main valve bonnet hexagon bolt, see
Fig.6. Locations shown in Fig.1.
•Refer to the disassembly and assembly procedures, 6.2 and 6.3, for
mounting the ring terminal.
•Use cable with insulated wires, stranded, 4 to 6.64 mm².

Fig.1
3.4 Piping Caution
•Before connecting piping make sure to clean up chips, cutting oil, dust
etc.
•When installing piping or fittings, ensure sealant material does not
enter inside the port. When using seal tape, leave 1.5 to 2 threads
exposed on the end of the pipe/fitting.
•Tighten fittings to the specified tightening torque.
3.5 Valve mounting - JSXFE and JSXFH
3.5.1 JSXFE Warning
•The compression fitting is used to seal the connection between the
valve and the pipework. Do not rely on the compression fitting to
support the piping as it could become detached. Ensure that inlet and
outlet piping is secured with separate fixings.
Caution
•Mount the valve to fixed metal piping (to ensure correct sealing of the
fitting, do not expose the piping to oil or moisture).
•Insert the piping into the valve body until it stops to prevent
misalignment of the piping in relation to the valve body, see Fig.2.
