(1) How to Clean Regulation Valves
The PRESSURE ADJUST and VACUUM ADJUST valves should be
occasionally inspected and cleaned.
• Remove the valve elements by turning the adjustment screws CCW.
Use a cotton swab or clean cloth to clean out dirt or grit around the
venting holes.
• Remove BALL and SPRING. Clean the areas around valve seating
surfaces in the VALVE BODY and elements.
• Reassemble VACUUM ADJUST and PRESSURE ADJUST valves.
IMPORTANT: Note that in the VACUUM valve, the SPRING must
go back in first, followed by the BALL. In the PRESSURE valve, the
BALL must go back in before the SPRING.
(2) Motor Overload Protection
The pump motor has an internal thermal overload switch which may
trip if abnormal operation occurs. If the motor stops, check the pump.
If you find no defect, allow the motor to cool for approximately 30 minutes, then restart. If the overload trips again—and no external source
causing the overload can be identified—return the complete unit to
your dealer for repair. (Refer to PRODUCT RETURN section at the
end of the manual.)

SAFETY PRECAUTIONS
WARNING: PRODUCT USE LIMITATION
These products are not designed for, nor intended for use in patient
connected applications; including, but not limited to medical and dental
use and accordingly, have not been submitted for FDA approval.
DANGERS: Unplug power cord before any cleaning operation is started.
Improper use of grounding plug can result in a risk of electric
shock.
WARNING: Gas under pressure should not be used for supply as a hazardous bursting condition could develop in the pump head.
Use only gases contained at atmospheric pressure.
CAUTION: Do not operate pump when pressure ports of both heads are
in a blocked condition.
To Remove the Pump Head
Remove the eight (8) screws holding the pump head to the pump housing.
Do not discard. With the ‘old’ head off, examine the diaphragm for cracks or
loose particles. Deep cracks would suggest that the diaphragm should be
replaced. Normal operation will cause some particles to be worn from the
diaphragm. Wipe the diaphragm clean with a dry cloth or one dampened
with alcohol. If not removed, these particles could affect the performance of
the valves.
To Replace the Diaphragm
Remove the eight (8) screws holding the pump head to the housing. Do
not discard. Slide the diaphragm away from the motor and then lift upward.
Unscrew the bearing collar assembly from the diaphragm. Examine the
bearing; check that the “needles” rotate freely. Install the new diaphragm
onto the bearing collar. Hold the diaphragm center plate, not the rubber
portion of the diaphragm, while the assembly is tightened. Rotate the
eccentric (attached to the motor shaft) by hand while applying grease to the
dowel pin. Use a wooden toothpick or something similar. Don’t scratch the
pin by using a metal object.
To Install the Diaphragm
Rotate the eccentric so that the dowel pin is “upward.” Slide the diaphragm
toward the motor, while gently pushing downward. Align the diaphragm
bead with the groove in the pump housing. It is recommended that a new
pump head be installed whenever a diaphragm is replaced. Excessive wear
particles from the old diaphragm may have entered the valves and
decreased their performance.
To Replace the Pump Head
Position the new pump head so that the flat edge is located toward the
motor. Care should be taken to align the diaphragm bead to the recess in
the pump head before the screws are tightened. Use the original screws to
attach the head onto the housing. IMPORTANT: tighten the screws alternately, at opposite sides of the head, so that it will seat evenly. Use two
steps—first, tighten all to approximately 50 oz-in, then tighten to 100 to 110
oz-in.
CAUTION: Do not disassemble the pump housing from the motor. Proper
assembly (factory adjusted) is critical to proper pump performance.

MAINTENANCE PROCEDURES
INTRODUCTION
The Vacuum/Pressure Station can be serviced without removal of the
pump.
The introductions in this manual are task-oriented. You can go directly to a
particular section and quickly find the answers. The step-by-step installation and setup instructions are easy to follow. Also, functions for all the tubing connections and adjustment valves are defined at the front of the manual for easy reference.
Service Kit 7530-09 contains a pump head assembly, a diaphragm assembly, and grease. The pump head consists of two valves and two valve
retainers installed in the pump head. The diaphragm assembly consists of
a set screw installed in the diaphragm center plate to a calibrated height.
The grease is needed whenever a diaphragm is replaced.
Pressure vs. Vacuum
In relation to atmospheric air, pressure can be positive or negative in a
closed space. In positive pressure applications, the pump compresses
atmospheric air to perform work, usually expressed as pounds per square
inch (psi). In negative pressure applications, the pump reduces the pressure of the atmospheric air to create a vacuum (or suction) to perform work,
usually expressed as inches of mercury (in Hg).
