Handling instructions and Precautions (FRZB Filter Regulators)
Filter regulator
(With water and fluids removal functions)
●
Removing the knob
Use the following procedure to remove the knob.
①
Release the knob lock.
(For how to release the knob lock see "Locking and releasing
the knob" on page
.)
②
Turn the mounting ring counterclockwise (in the direction of
the arrow in the diagram below).
③
Pull the mounting ring over in the direction of the knob.
④
Pull off the knob and the mounting ring together.
●
Attaching the knob
1.
Use the following procedure to attach the knob.
①
Release the pressure of the IN port (primary) side to the
atmosphere.
②
Screw on the mounting ring.
③
Press the knob in until the yellow caution ring is not visible.
Note
Turn the mounting ring until it comes off the threads.
Note
Installing the knob before screwing on the mounting ring
makes it impossible to attach the mounting ring and makes
the knob difficult to remove.
Note
The release sleeve of the mounting ring must be pulled up
until it spreads the hooks (3 places) on the knob.

If it is impossible to release the pressure on the IN port (prima-
ry) side to the atmosphere, the pressure on the OUT port (sec-
ondary) side will rise temporarily, check for any effect it may
have had on downstream equipment and devices, and then
attach the knob.
2. Attaching the knob while the filter regulator IN port (primary)
side pressure is being applied, may cause a temporary rise in
pressure on the OUT port (secondary) side pressure.
Before attaching the knob, always release pressure on the IN
port (primary) side to the atmosphere, because a temporary
increase in pressure on the OUT port (secondary) side may
occur which may damage equipment or devices on the OUT
port (secondary) side or cause a malfunction.
Note
It may damage the equipment or devices or injure workers
or operators.
Note
Before pressing on the knob, align the square part of the
adjusting assembly (refer to the exploded view on page
)
and the square indented portion of the inside of the base of
the knob before pressing the knob on, so the knob is easier
to press on.

pressure port plate
1.
Be sure to release any pressure in the system before replacing
the
□

2.
Use the following procedure to change the
□
1.181 in. integrated
pressure gauge or pressure port plate.
①
Remove the two small screws.
②
Remove any metal chips from the female thread hole with
compressed air blow.
③
Put the O-ring on the
□
1.181 in. integrated pressure gauge
or pressure port plate.
④
Align the groove on the
□
1.181 in. integrated pressure gauge
or pressure port plate with the tongue on the main unit and
attach it.
⑤
Tighten the two mounting screws to 0.66 to 0.81 ft

Note
If there are any metal chips left, they may break the threads
or get on the o-ring and cause an air leak.
Note
If torque exceeding the specifications is applied, the head of
the screw or threads may be damaged and cause damage to
component parts. Also, if torque below the specifications is
used, the screw may come loose and cause an air leak.

Drain cock operation
1.
Turn the drain cock with your hand.
2.
