SECTION 4: MAINTENANCE 

4.1.1.4 

EVERY 32,000 HOURS OR 48 MONTHS 

Attention / Warning! 

DO NOT REPRESSURIZE DRYER OR RECONNECT POWER TO THE DRYER 
YET! 

1.  Drain all the desiccant from both vessels through the drain at the bottom of each 

vessel. If a handhole / manway is available, the desiccant can be removed using 
a vacuum truck 

(recommended)

. 

2.  Refill both vessels with the proper amount of desiccant. Reference the 

"Documentation" section of this manual for the Specification Sheet and Spare 
Parts list which indicate the required desiccant quantity. Reference the 
"Maintenance: Fill-Up / Replacement of Desiccant" section of this manual for the 
desiccant fill-up/replacement instructions. 

On the CATR heatless air dryer, fill through the standpipe; it is important to 
make certain the standpipe is completely filled with desiccant! 

3.  Rebuild the actuators and valves by installing repair kits in the major switching 

valves. 

4.  Carefully disassemble and clean the solenoid valves in the control group; rebuild 

with new parts, only if damage or serious wear is evident. 

5.  Make certain all air and electrical connections are sound. 

6.  Repressurize the dryer (or filters) and place "onstream". 

7.  Reconnect power to the dryer.
