4.1 DRYER SHUT DOWN PROCEDURE
Before performing any maintenance or service operations on this product, ensure the product
is isolated from the compressed air supply and fully depressurised. Also ensure the product is
switched o and/or isolated from the mains power.
PROCEDURES
• Isolatethecompressedairsupplytothedryer(Inletandoutlet)
In order to fully depressurise the dryer;
- Allow the dryer to cycle twice to ensure the dryer exhausts and is completely depressurised.
- When fully depressurised the‘clicking’of the exhaust valves will be heard but no air
exhausted.
- If Energy Saving enables, you may need to power down the dryer, wait 5 minutes, and restart to
prevent ES Mode enabling to fully shut down.
• Whenthedryerisfully depressurised, isolate from the power supply.
4.2 DRYER START-UP PROCEDURE
•Ensure all isolation valves are closed
•Ensure the inlet operating pressure parameters are between 58-145 psig (4-10 barg).
•Ensure the inlet air temperature is between 35°F - 122°F.
•Slowly open the inlet valve and allow dryer to pressurise.
•Turn on the power to the dryer.
•Open the outlet valve.
•The dryer will display its status and commence normal operation. When the dryer is powered up the display will
show“Starting”for approximately 20 seconds, untill displays the columns status,“purge” or “online”.
•Ensure all pipe work is connected.
