2.8 shutdown procedure
Isolate unit from compressed air system.
The unit will still be pressurized
Ensure the unit is fully depressurized and isolated
To fully depressurize, following the steps below;
• Once isolated from the compressed air source
• Cycle the dryer at least twice to ensure the unit exhausts and is completely depressurized.
• When fully depressurized the ‘clicking’ of the exhaust valves will be heard but no air exhausted.
• When the unit is fully depressurized, isolate from the electrical supply.
• Press  to to return to l.

2.9 start-up and operation
Do not allow the unit to ow air unless switched on and cycling. Resulting effect could be desiccant
contamination; requiring a desiccant service.
• Ensure all pipe work is connected as per the typical layout
• The unit is connected with a power supply as stated on the rating label.
• Ensure the inlet air pressure is with in limits as stated on the rating label on the product.
• Ensure the inlet air temperature is with in limits as stated on the rating label on the product.
• Slowly open the inlet ball valve and allow the unit to pressurize
• Turn on the unit, the unit will display its’ status. Press 1
• Allow the unit to cycle at least 2 times before slowly opening the outlet ow.

This unit must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric
shock by providing an escape wire for the electric current. This unit is equipped with a cord having a grounding
wire with an appropriate grounding plug. The plug must be plugged into an outlet that is properly installed and
grounded in accordance with all local codes and ordinances. Do not modify the plug provided; if it does not t
the outlet, have the proper outlet installed by a qualied electrician.
After 10 minutes of inactivity, the HMI will enter an energy saving mode where the HMI screen will go black. A green LED will
remain lit at all times to indicate the HMI is still fully functional. If at any point the HMI detects human interaction the energy
saving mode will deactivate and the screen will revert back to the main display seen above.
