Page 41: Cooling Fan
C O M P O N E N T T E S T I N G , R E P A I R & R E P L A C E M E N T Cooling Fan The cooling fan provides a constant air flow to cool the compressor. A defective cooling fan may cause the compressor’s internal thermo-protective device to activate and shut the compressor off. - Page 42 C O M P O N E N T T E S T I N G , R E P A I R & R E P L A C E M E N T The four-way valve, while operating pneumatically, uses an external pilot valve that allows pressure to shift the spool inside the four- way.This pilot valve receives a signal (12-15 VDC) from the PC board causing it to open and allowing pilot pressure to activate the four-way.When the four-way is activated, the left sieve bed will pressurize.
- Page 43 C O M P O N E N T T E S T I N G , R E P A I R & R E P L A C E M E N T If the left bed does pressurize first, observe whether pressure is shifted to the right bed once the shift point pressure is reached or if the left bed proceeds to pressurize again.
