F.R.L. Unit Precautions 2
Be sure to read before handling
Mounting
Caution
1. To avoid reversed connections of the air inlet/outlet, make
connections after confirming the “IN/OUT” mark or arrows that
indicate the direction of air flow. Reversed connections can cause
malfunction.
2. Components with a bowl, e.g., air filter, filter regulator, lubricator,
must be installed vertically with the bowl downward so that faulty
drain discharge and dripping can be verified.
3. Ensure sufficient top, bottom, and front clearance for maintenance
and operation of each component. Refer to the dimensions section
for the minimum clearance for each component.
4.
Regulator and filter regulator
Be sure to unlock the knob before adjusting the pressure and to
lock it after the pressure is set.
Adjustment
Warning
1.
Regulator and filter
regulator
a. Set the regulator while verifying the displayed values of the inlet
and outlet pressure gauges. Turning the knob excessively can
cause damage to the internal parts.
b. Do not use a tool on the pressure regulator knob as this can
cause damage. It must be operated manually.
Caution
1.
Regulator and filter regulator
a. Be sure to check the inlet pressure before setting the outlet
pressure.
b. To set the pressure using the knob, turn the knob in the
direction that increases pressure and lock the knob after the
pressure is set. If this is done in the direction that decreases
pressure, the pressure may drop from the original set pressure.
Turning the knob clockwise increases the outlet pressure, and
turning it counterclockwise reduces the pressure.
Piping
Warning
1. To screw piping materials into components, tighten with a
recommended tightening torque while holding the female thread
side. If the minimum tightening torque is not observed, this can
cause a looseness and seal failure. On the other hand, excess
tightening torque can cause damage to the threads. Furthermore,
tightening without holding the female thread side can cause
damage due to the excess force that is applied directly to the
piping bracket.
Recommended tightening torque
Unit: lb.- ft.
Connection Thread
3/8"
1/2"
Torque
16.2 to 17.7
20.6 to 22.1
* Alternatively tighten by hand, then tighten further approximately 1/6
turn using a tightening tool.
2. Avoid excessive torsional moment or bending moment other than
those caused by the equipmentʼs own weight as this can cause
damage. Support external piping separately.
3. Piping materials without flexibility such as steel tube piping are
prone to be affected by excess moment load and vibration from the
piping side. Use flexible tubing in between to avoid such an effect.
