Disconnect main power supply to dryer

Lock out and tag power supply in accordance with OSHA requirements

Remove screw and washer from front of valve

Remove the power supply connector and gasket from the solenoid coil housing. Do not damage or lose the gasket.

Remove 13mm nut and spring washer from top of solenoid coil housing

Lift solenoid coil housing off solenoid core in valve body

Unscrew solenoid core from valve body

Check the operation of the automatic drain valve at least once during each 8-hour shift.

Dryers with the Intelli-Dry Controller

Check the High Temperature Alarm LED.

Check the Low Temperature Alarm LED.

Dryers with Optional Intelli-Dry RX Controller

Warning: This procedure requires trained personnel with PPE!

Fouling: Biological and organic substances (slime) can also cause problems, but in elevated temperature environments such as cooling processes they are not a major concern. If they create problems with clogging, commercial shock treatments are available.

To ensure continued good operation and performance of the dryer cooling system, the recommended ranges for different water constituents are below.

Dissolved oxygen - Concentration

Is the Dissolved oxygen concentration 0 ppm (as low as possible)?

DANGER: Vent internal pressure to atmospheric pressure before performing any maintenance.

Vent the internal pressure to the atmosphere. Refer to the shutdown instructions.

Disconnect drain lines at manual and automatic drain valves (if installed).

DANGER: A 'hissing' sound while the bowl is being removed indicates the filter has not been properly depressurized. DO NOT continue to remove the bow until the filter has been completely vented to atmospheric pressure.

Remove the bottom bowl by unscrewing it from the head. A strap wrench may be needed.

Remove the element from the filter head with a brisk downward pull, or by working the element back and forth until it snaps free. Discard the element in accordance with applicable regulations.

Clean accumulated debris from the bowl with soap and water, and dry thoroughly.

CAUTION: Lubricate the O-ring with a petroleum-based lubricant compatible with your application.

Lightly lubricate the new element O-ring before installing the new element.

Warning: This procedure requires trained personnel with PPE!
