8. MAINTENANCE AND SERVICE
8.1 Routine Maintenance
The service must be carried out only by a qualified technician.
Before any service is carried out, always verify that:
 The power has been disconnected following proper Lock-out, Tag-out procedures
 Depressurize the unit and ensure the unit is isolated from the compressed air system (see pg 14)
The personnel that service the machine must wear hearing and eye protection before operating the dryer.
Each employee must select a proper personal protection device (PPD) hearing protector such as earmuffs,
ear canal caps or earplugs in order to prevent permanent hearing damage or loss.
DAILY
 Check that pre-filter condensate drain is working properly
 Check the differential pressure of any installed pre and post filtration
 Check that the tower switching operation takes place correctly at the set cycle times.
 Check that the tower pressure gauge of the regenerating tower reads 0 psig while the drying tower
reads full line pressure
ANNUALLY
 Replace the pre and post filter elements
 Replace the exhaust silencers
 Replace the pre-filter float drain or iMAT service unit
 Check if the solenoid valves are working properly
 Check if all screws of the electrical wiring are securely tightened
 Verify operation of the dryer
EVERY 2-YEARS
In addition to the scheduled annual maintenance:
 Install inlet and purge exhaust valve service kit
 Verify operation of the dryer
EVERY 3-YEARS
In addition to the scheduled annual maintenance:
 Replace the desiccant adsorption material in both towers
 The estimated average lifespan of the adsorption material is 3-5 years when using 10-minute cycle
times or 3,000 operating hours per year. In all cases, the lifetime of desiccant material is heavily
dependent on the quality and temperature of the inlet air and ensuring that scheduled maintenance
is consistently carried out.
 Verify operation of the dryer
