( OUTP ) rises above the alarm set point for more than one (1) minute.
(Default setting is 10.0 PSI for Standard models / 7.50 PSI for LP models)
See section 13.5 for troubleshooting information.
8.6.2 Low Outlet Pressure Alarm –
Occurs when the Outlet Pressure
( OUTP ) drops below the alarm set point for more than one (1) minute.
(Default setting is 2.0 PSI for Standard models / 0.30 PSI for LP models)
See section 13.7 for troubleshooting information.
8.6.3 High Humidity Alarm –
Occurs when the Humidity level rises above the alarm set point for more than one (1) minute.

8.7 Adjusting & Resetting Dryer Set Points
Dryer Set Points are simply limits programmed for a specific reading. Once this limit is reached (or exceeded) this results in an alarm for that reading. Each of these set points is factory programmed with a default value based on typical usage of the air
Dryer. Many of the set points for Dryer alarms can be modified to levels more closely based upon your specific application.

9. Testing Your Dryer
9.1 Safety & Warning Information
P550W Series Air Dryers User’s Guide
WARNING!
Extreme care should be exercised to avoid contact with live electrical circuits. Many procedures performed during installation, operation, testing, and maintenance of this air Dryer require the equipment to be running, creating a situation for potential electrical shock. It is highly recommended that you remove all jewelry before performing any procedures.
WARNING!
Internal surfaces may be hot . Use care when coming into contact with internal components as there is a potential for some of these components to become hot when in operation or standby.
CAUTION!
Depressurizing the air Dryer may be necessary before performing certain procedures. NEVER remove pressure sensing tubes from the control board without depressurizing the air Dryer first, or damage to the control board will occur.

9.8.2 Use a Voltmeter to measure the DC voltage across each set of “ VALVE ” terminals.
Continue to measure for up to
45 seconds if no voltage is initially measured.
The voltage should measure 53 Volts DC .
If the voltage does not measure 53 Volts DC, this is an indication that the Cycle

NOTE: The fan will turn OFF when the cabinet temperature is below 80
F.
If the fan is not blowing air outwards as described:
•
Verify the cabinet temperature is above 90
F.
•
Check for loose wiring. Refer to the Wiring Diagram (section 14.1 )
•
Replace defective fan (see sections 11.1 for part detail and 11.5 for
ordering information).
•
Replace defective control board if fan does not respond properly to
temperature changes (see sections 11.1 for part detail and 11.5 for
ordering information).

9.15 Testing Air Fittings & Hoses for Leaks
NOTE: This is a general procedure that can be applied to any fitting or hose that has air pressure in it. DO NOT SOAP TEST THE HUMIDITY SENSOR
FITTING. DAMAGE TO THE SENSOR MAY OCCUR.
With Compressor NOT running:
9.15.1
Listen for any ‘hissing’ sounds which may indicate a fitting or hose air leak.
With Compressor running:
9.15.2 Use a 1-inch paint brush to dab soapy water on the air fitting or hose connection to be tested.
If air bubbles appear at the connection, this indicates that air is leaking from the connection.
If any leaks are detected, take steps to seal them off (as necessary):
•
Tighten the fitting
•
Re-connect the hose end
•
Replace the fitting / hose / component

10. Maintaining Your Dryer
P550W Series Air Dryers User’s Guide
In order to ensure that your P550W Series Air Dryer continues to operate efficiently and reliably, PUREGAS recommends performing the following maintenance procedures at the specified Six Month and 8,000 Hour intervals.
It is also recommended that you print out the included Six Month Maintenance (section
and 8,000 Hour Maintenance
log sheets and record all completed maintenance for historical tracking and reference purposes.
The log sheets include a Section reference column which indicates the User’s Guide section containing the information about the specific procedure. Please refer to these sections for detailed procedural information.
NOTE: When operating at higher ambient temperatures, it is recommended that maintenance be performed more frequently.
NOTE: After 16,000 hours of run time, PUREGAS recommends sending in your compressors and heatless dryers for a complete and comprehensive rebuild by our
Service Department technicians.
See sections 12.1 and 12.2 for information on
services and contacting PUREGAS.
10.1 Safety & Warning Information
WARNING!
Extreme care should be exercised to avoid contact with live electrical circuits. Many procedures performed during installation, operation, testing, and maintenance of this air Dryer require the equipment to be running, creating a situation for potential electrical shock. It is highly recommended that you remove all jewelry before performing any procedures.

P550W Series Air Dryers User’s Guide
Internal surfaces may be hot . Use care when coming into contact with internal components as there is a potential for some of these components to become hot when in operation or standby.
SHUT DOWN IMMEDIATELY FOR REPAIRS if the air compressor shows any evidence of overheating or presents excessive noise.
Depressurizing the air Dryer may be necessary before performing certain procedures. NEVER remove pressure sensing tubes from the Control Board without depressurizing the air Dryer first, or damage to the Control Board will occur.
Performing routine maintenance as outlined in the Maintaining
Your Dryer section will ensure optimal performance over the lifecycle of your air Dryer.
Performing procedures not described in this User’s Guide or installing components not supplied by PUREGAS is NOT
RECOMMENDED AND MAY VOID THE WARRANTY.
After performing any maintenance, always soap test pressure fittings to check for air leaks. Also, check for any loose or disconnected wiring.

No claims for labor in replacing defective parts or for consequential damages will be allowed. Replacement parts will be invoiced in the regular way, with invoices subject to adjustment after the parts claimed defective are examined at our factory. In addition, no material or parts will be accepted at our factory for in-warranty repairs or credit without previous authorization from PUREGAS.
Responsibility for damages incurred in transit will be borne by the user and the user in turn should file any damage claim against the carrier. All warranty items are F.O.B.

This warranty shall not apply to any PUREGAS product which shall have been repaired or altered in any way by anyone other than PUREGAS or authorized personnel so as to affect, in our judgment, its proper functioning or reliability, neither will it apply to any product which has been subject to misuse, negligence, or accident. The installation of unauthorized non PUREGAS parts will void the warranty on those PUREGAS products.
