11. OTHER DRYER CHECKS & NON-SERVICEABLE    

      ITEMS

DAILY CHECKS

Visual and functional check of the dryer should be carried out daily: 

• 

 Check the dryer for any external damage.

Assess and eliminate any defects found.

• 

If the red service light appears, the dryer must be serviced.

Contact the service department and request a dryer service kit.

• 

Remove any loose dust or dirt from the dryer; clean all surfaces that appear to have attracted unwanted 
contaminants.

• 

Check the dewpoint sensor display (where applicable). If the dew point is not achieved the dewpoint  
reading on the display will alternate with “dewpoint alarm” every 5 seconds. The no-volt alarm will also 
activate.

Contact the service department and request a product service.

MAINTENANCE GUIDELINES
• 

Maintenance operations only to be conducted when the system has been shut down and fully  
depressurised. 

• 

All connections must be undone with care, paying particular attention to the areas that become  
pressurised. 

• 

Do not modify or adjust the control settings. 

• 

Only certified n-psl approved replacement parts to be used. 

• 

Always check all connections for leakage and secure seating. 

• 

Ensure all loose parts are removed or secured to the dryer before operation.
