SIZING GUIDE
Choosing the correct size STS to meet practice depends on the number of air users and the
anticipated air demand. To assure optimum operation, the demands should not exceed the
number of air handpiece users shown below. Each chart lists the number of simultaneous
High Volume Evacuators (HVEs) and Saliva Ejectors (SEs) that can be used in specific STS
systems.
Recommended Number of Simultaneous Users

SIZING GUIDE
Choosing the correct size AIRSTAR for your practice depends on the number of air
users and the anticipated air demand. To assure optimum compressor operation, the
air demands should not exceed the number of air handpiece users shown in the chart
below:

AH - .TL- bvicx, OPERATING INFORMATION
• AS10, AS21 and AS22
• If a remote Control Panel is being used, the circuit breaker on the face of the
compressor Control box must be in the ON position.
• The 24 volt circuit breaker must also be in the ON position. Make sure the reset
button is flush with the face of the circuit breaker. If it isn't, push it in to reset.
• If a Remote Control Panel is not being used, be sure that the yellow and the
orange wires are connected to one another. These wires are located in the
pressure switch. The circuit breaker located on the face of the compressor
Control Box is the power control for the motor.
• AS30, AS50 and AS70
• If a Remote Control Panel is being used, BOTH switches on the face of the com-
pressor Control Box must be in the ON position.
• If a Remote Control Panel is not being used, be sure that the yellow and the
orange wires are connected to one another. These wires are located on the pressure
switch. The power switches located on the face of the compressor Control Box are
the power control for each motor.
Note: Compressor motors are designed to run together. Do not run one head
at a time unless one head has failed and you are waiting for service.
• The motor circuit breaker must be kept in the ON position and should not be used
as a switch.
