1.3 Warranty 
 

This product has been factory tested before shipment.  It is guaranteed to be free from defects in material and/or workmanship for a 
period of 12 months from the date of shipment.  This warranty applies provided the machine has been installed and used in 
accordance with the instructions detailed in this manual.  The manufacturer agrees, at its discretion, to repair or replace all defective 
parts free of charge.  Further, the manufacturer agrees to cover charges associated with field labor required to make authorized 
warranty repairs, provided the PSB-General Air warranty policy is followed and an S.I.R. authorization is issued by PSB-General Air.  
Labor coverage shall be limited to maximum rates as published in the latest price list.  Field repairs may only be performed by a 
factory authorized service technician.  This warranty is limited to defects associated with operation and manufacture only.  All parts 
subject to wear due to their normal operation are not covered by this warranty.  All transportation costs associated with factory repair 
of equipment are the sole responsibility of the owner.

• 

Instruction and maintenance manual with wiring diagram. 

 

1.5 Description Of Operation 
 

These dryers have been specially designed to provide dry compressed air, while consuming electrical power in direct proportion to the 
actual load, thereby saving energy.  The dryers utilize mechanical refrigeration, in conjunction with thermal storage, to condense 
moisture by lowering the compressed air temperature to about 37°F.  The dryer “stores” its refrigeration ability during periods of low 
load by making ice.  This allows simple and efficient “on/off” control of the refrigerant compressor to be used for capacity control.  An 
air-to-air economizer is employed to minimize the size of the refrigeration plant and to save electrical energy.  Condensed moisture is 
accumulated in the built-in moisture separator and is discharged through the zero air-loss drain.  When the dryer is started it is 
automatically in the direct expansion mode and cools the compressed air by direct heat exchange with refrigerant.  When the sensor 
temperature drops below setpoint (indicating that the dryer capacity is in excess of the load), the refrigerant solenoid valve is closed, 
forcing refrigerant through the ice-making circuit only. The dryer continues to run, making ice, for a predetermined time interval after 
which the refrigerant compressor is switched off.  At this time, the LED displays the code “ICE” indicating that the dryer is cooling the 
compressed air by melting the ice-mass. When the sensor temperature rises sufficiently, indicating that the ice-mass has been 
depleted, the refrigeration system is re-started and the control cycle is repeated. 
 
 

ATTENTION: although this dryer is equipped with an on/off switch & internal individual component protection, complete unit 

over-current & short circuit protection MUST be provided by the installer, in the user’s power supply, before the dryer.
