Section VI - Troubleshooting

General Troubleshooting

Before specific identification of any fault 

is looked for, the following general points 

must be verified: 

Has the unit been damaged externally 

or are any parts missing? 

Is power being supplied to the unit? 

Was startup carried out in accordance 

with the instructions in this manual? 

Are all external valves correctly set for 

operation? 

Do the operational conditions meet 

those specified at time of ordering and 

used for product selection? 

The table below gives possible causes and 

corrective actions to faults that may occur 

on the dryer:
