(2)If the SAM-e is condensing inside the duct, make sure that the design conditions have not changed.

(3)If grommets leak, make sure the tubes are firmly inserted, if cracks or damage are found, replace grommet.

4.BLOWER PACKS TROUBLESHOOTING

A.PROCEDURE

(1)An optional blower pack (BP), ensure power supplied to blower pack either from humidifier or other source, if present, gets its primary voltage from inside the humidifier. This way, only one external power source has to be connected to the equipment. Confirm this power source before troubleshooting the blower pack.

(2)Ensure blower pack is installed per Chapter 10-10 Installation.

(3)If fans are not functioning, confirm safety is not open. Fans are only ON when steam is being discharged.

5.DIGITAL ON/OFF HUMIDISTAT SENSOR CALIBRATION

A.PROCEDURE

(1)The humidity sensor is factory calibrated, however, it can be field recalibrated.

(a)The calibration routine can be accessed by pressing and holding down the option button for five seconds. A new screen will appear with the calibration adjustments.

(b)Press the up or down buttons until the text calH appears on the LCD screen.

(c)To adjust the calibration press the Option button. The screen should load to display the current calibration trim. The calibration trim can be adjusted by pressing the up or down buttons to the desired level and then pressing the option button to confirm the settings.

(d)Press the Power button to return to the normal display.
