3-3. Main Air Pressure Regulator
Specification
The case sealer requires a compressed air supply of
75  140 PSIG [5.2  9.5 BAR] 7.0 SCFM
[11.89 m3/h, 21oC, 101 kPa] maximum at maximum
cycle rate.
The optimum operating set point on the gauge is
95  100 PSIG.
Adjustment
ü Note
If the pressure is lower than that specified, check the
input pressure at the source. If the source pressure is
lower than 75 PSIG [5.2 BAR], there is not enough
pressure to operate the case sealer properly. Also
note that the inner diameter and length of the
incoming air supply can affect final air pressure and
recovery rate SCFM.
If the pressure at the source is between 75  140
PSIG (this is the maximum pressure shown on the
gauge), make the following adjustment.
1. Refer to Figure 3-2. Adjust the Main Air Pressure
Regulator to read 95  100 PSIG on the gauge
(CW  increases pressure, CCW  decreases
pressure).

3-4 . Box Centering Pressure Regulator
Specification
The Box Centering Pressure Regulator should be
set to permit positive centering of the various
weights of boxes the customer is using. Set the
pressure to provide sufficient centering force
without creating excessive drag. Keep in mind the
maximum box weight capacity (filled) is 65 pounds,
and the minimum weight must be sufficient to hold
the case on the conveyor bed with the bottom flaps
flat.
Adjustment
1. Refer to Figure 3-3. Adjust the Box Centering
Pressure Regulator on the underside of the
Pneumatic Control Panel (CW  increases
pressure, CCW  decreases pressure). Observe
the Box Centering Pressure Gauge on the top of
the panel.
