Checklist
Routine maintenance will ensure optimum operation and performance of the
W Series Carousel Plus Dryer. We recommend the following maintenance
schedule and tasks.
• Whenever you change materials
❒ Drain and clean the hopper.
• Weekly, or as often as needed
❒ Clean or replace the process and regeneration filters.
You may need to clean filters more often than weekly. Frequency depends
on how much material you process and how dusty or full of fines it is.
❒ Inspect hoses and hose connections.
Check for damage, kinks, or loose hose clamps. Replace any hoses that
show signs of damage or wear. Reposition and tighten loose hose clamps.
• Monthly
❒ Clean the aftercooler/intercooler and/or optional precooler coils.
You may need to clean the coils more often than monthly. Frequency will
depend on the type and volume of material you process.
• Every six months
❒ Inspect gaskets for damage or wear.
Damaged gaskets can allow moisture to seep into the closed-loop drying
system. Replace any gasket that is torn or cracked.
❒ Inspect the overhead process air duct connections.
(W3200-5000) Ensure that all connections are tighten properly and have
no air leaks.
❒ Verify dewpoint readout and performance with calibrated portable
instrument.
❒ Measure current draw on all 3 legs of heater wires. This is to ensure
that the heater is working properly.
