Section 5 - Desiccant Replacement (cont’d) 

9. Remove and replace the pre & afterfilter elements prior to putting the unit back in service. This is accomplished by
unscrewing the bowls and following the kit instructions to replace the elements. We would be happy to look at the old
elements if you feel there is any question as to the condition. Please contact the factory for shipping instructions. Replace
the filter bowls and tighten securely prior to re-pressurizing the  unit.

10. Turn the power back on to the  unit.

11. Close the discharge valve of the unit, and open the valve ahead of the coalescer. Turn power back on to the unit and
allow the unit to repressurize. Check all joints for leaks and tighten if needed.

12. Operate the drain valve manually to bleed air to force the dryer through a full cycle to ensure that the towers
pressurize and repressurize correctly and go through their cycle. This is simply a check to see that the unit is operating
normally. The unit is now ready to go back in  operation.

Run the unit for a 1/2 hour as above in INSTALLATION, before letting air feed back into the system.

 

The purge mufflers must be removed during this 1/2 hour period. 
Reinstall the mufflers only after the unit has run for a 1/2 hour.

 

Once this has been done, valve the unit back into the  system.

 

Should you have any questions, please call the factory and ask for Customer Service at 1-800-345-8207.
