MAINTENANCE
WARNING:
Not following proper procedures could cause the product to malfunction and could
lead to damage to the equipment or machine.
If handled improperly, compressed air can be dangerous. Assembly, handling and
repair of pneumatic system should be performed by qualified personnel only.
Drain: remove condensate from the filter bowl on a regular basis.
Shut-down before maintenance: before attempting any kind of maintenance make
sure the supply pressure is shut off and all residual air pressure is released from
the system to be worked on.
Start-up after maintenance: apply operating pressure and power to the equipment
and check for proper operation and possible air leaks. If operation is abnormal,
please verify product set-up parameters.
Do not make any modification to the product.
Do not disassemble the product, unless required by installation or maintenance
instructions.
After removing the socket with a wrench, etc., lift off the plate, wave washer and cover,
and replace the coil assembly. After replacing the coil, first tighten the socket by hand
while holding down the plate and wave washer, and then tighten it further with a torque
of 0.8 to 1N·m.
Precautions when attaching and removing the socket.
Be careful that the O-ring installed on the bottom (plate side) of the socket does
not fall out or become chewed up, etc.
Be sure to hold the body with a wrench, etc., and tighten the socket within the
tightening torque range given above. if excessive torque is applied, there is a
danger of damaging the threads.

LIMITATIONS OF USE
Leakage
Particularly when using a resistor in parallel with a switching element and using a C-R
element (surge voltage suppressor) to protect the switching element, take note that
leakage current will flow through the resistor and C-R element, etc., creating a danger
that the valve may not shut OFF.
Low temperature operation
The valve can be used at ambient temperatures as low as -10°C, but take measures to
prevent freezing or solidification of impurities, etc.
When used in cold areas with water, etc., adopt freeze prevention measures such as
draining the water from pipelines after pump operation has been stopped. If warmed
with a heater, etc., avoid the coil unit. Also, implement warming or other freeze
prevention measures for the body.
