ZEKS recommends changing the element in the Cold Mist Eliminator (ZEKS P/N
683532) at 6 psid.  Access to the element is gained by removing the top panel of the
dryer and removing the flange bolts from the element housing.  After replacement of
the filter element, reinstall flange and flange bolts and reattach dryer top panel. 

6.3    MOISTURE REMOVAL SYSTEM

Liquid droplets are removed from the air stream in the separator.  As the air and
liquid mixture passes through the separator it spins, slows down and then changes
direction.  This causes the condensate to fall out of the air stream and collect in the
bottom of the separator.  The collected liquid is removed from the separator by a
solenoid valve.  The solenoid valve is controlled by the microprocessor controller as
described in Section 6.6. For adjustment please note the following:

•  To obtain the optimum time values for operation of the solenoid drain valve, set 

the OFF-time to 5 minutes and the ON-time to 5 seconds via the controller.  

•  After running the unit under full rated flow for approximately 30 minutes, verify that

when the solenoid drain opens, all of the accumulated liquid is discharged followed
by a short burst of air.

•  If a small amount of liquid and a large amount of air is discharged, decrease the 

ON-time setting or increase the OFF-time setting.  If only liquid and no air
discharges, increase the ON-time setting or decrease the OFF-time setting.

•  The ON/OFF time settings will vary according to seasonal operating conditions.  

During the summer when more moisture is present in the air system a shorter 
ON-time is required to increase the valve opening frequency.  A longer valve 
OFF-time may be used during winter months when moisture levels are lower. 

On units equipped with the optional Cold Mist Eliminator, a timed electric drain is
used to remove liquid droplets from the Cold Mist Eliminator.  For adjustment please
note the following:

...

• To obtain the optimum time values for operation of the electric drain valve, set the 

OFF-time adjustment knob to 5 minutes and the ON-time adjustment knob to 10 
seconds.

...

• After running the unit under full rated flow for approximately 30 minutes, verify that

when the electric drain opens, all of the accumulated liquid is discharged followed
by a short burst of air.

...

• If a small amount of liquid and a large amount of air is discharged, decrease the 

ON-time setting or increase the OFF-time setting.  If only liquid and no air
discharges, increase the ON-time setting or decrease the OFF-time setting.
