MAINTENANCE

Table 25-1:
 Ultra-sorb Model MP troubleshooting

Problem

Possible cause

Action

Control system 
malfunctioning

• Incorrect control voltage

• Replace transformer.

• Incorrect control signal

• Replace components.

• Improper wiring connections

• Rewire.

• Incorrect humidity sensor

• Replace.

•  Humidity controller out of calibration

• Recalibrate.

Air cannot absorb 
steam quantity being 
discharged

• Humidifi er operates when blower is off

• Provide interlock.

• Valve is hunting

• See above. 

•  Air temperature in duct too low for steam 

quantity being emitted

• Raise duct air temperature.

Humidifi er is noisy

• Steam pressure too high

• Reduce pressure.
