Corrective Action for Installation Failures

First ensure that the breaker supplying the dryer is operational.

If it is, disconnect the power and remove the dryer cover.

Taking suitable precautions to avoid shock hazard, reconnect the

power and check for Voltage at the terminal block.

Verify that connections are made correctly.

Ensure that there is no obstruction on or in front of the IR sensor.

Clean any dirt or debris off the sensor lens. If problem persists,

replace sensor.

Ensure that the supply Voltage is correct. Dryer will make a loud

humming noise if the input Voltage is too high. Verify Voltage

requirement on the unit rating label and correct supply as

required. If CBM has been damaged replace CBM, IR sensor

module.

Ensure that the supply Voltage is correct. Dryer will run weakly if

the input is too low. Verify Voltage requirement on the unit rating

label and correct supply as required.

signs of burning or breakage. Damaged element must be replaced.

Check the output nozzle for obstructions. If none are present,

disconnect the power. Remove the dryer cover. Remove any

dust/lint build up from intake vent slots. Check VR for speed

setting. Disassemble the blower-motor/fan housing. Check the

motor brushes for worn condition (≤ 30mm graphite remains)

and replace them, if necessary.
