Weekly
Check air flow rate, air inlet pressure and temperature are within design specifications of dryer.
Check blower and blower inlet filter. (Blower purge models only).
Semi-annual
Check the condition of the prefilter and afterfilter elements. Verify the differential pressure across the filters.
Replace as needed.
Check desiccant quality. Desiccant from a freshly regenerated bed should be white, dry to the touch and of consis-
tent size and shape. Continuous adsorption and desorption causes the performance level of desiccant to decline
over time. Oil and contaminants causes reduction in the adsorption ability of the desiccant. It is recommended to
replace the desiccant every 3-5 years.
Check exhaust mufflers and verify there is no back pressure in regenerating vessel. If the muffler is clogged, it must
be cleaned or replaced.
Tighten wire connections to heater. Stud terminals should be tightened to a maximum torque of 20 in-lbs while the
bottom nut is supported. Stud terminals that do not have a bussbar or factory installed ring connector should only
be tightened to 9 in-lbs.
Check condition of blower inlet filter element and replace as needed. (Blower purge models only).
Inspect blower drive belt and idler pulley. Replace if needed. (Blower purge models 4000-9000 only).
Annual
Check condition of control air filter element. Replace as needed.
Check condition of all inlet and exhaust switching valves. It is recommended to clean and rebuild the valves to
maintain proper working condition.
Check dewpoint sensor and recalibrate as needed.
Check contactors and starters. Replace as needed.
Inspect blower head, tensioner, and pulleys for correct operation. (Blower purge models 4000-6000 only.)
