b. Press ‘ESC’ at any time to return to the Main Menu.
NOTE: On dryers with air-cooled condensers, regular

condenser cleaning is recommended. Dirtiness

of ambient air at installation site will determine

frequency of service. Typically once a month is

recommended. Dryers contain an integral 3 micron

filter. As the filter element accumulates solid

contaminants, differential pressure increases. Solid

particulate load in the compressed air supply will

determine frequency of service. Typically element

changeout is recommended at least annually.

water flow.

2. Check for proper electrical voltage.
3. Slowly pressurize unit air side by opening inlet isolation

valve. Check for leaks.

4.  After 15 minutes, open outlet isolation valve slowly.

dryer if an unusual noise is heard and the discharge line

does not get hot, stop the dryer, reverse two power leads,

restart, and verify discharge line gets hot.
