Use
Hour
and
Minute
buttons to enter the number
of operating hours (service interval) before service
reminder is initiated. Maximum setting is 4090 hours.
(Only hours that refrigeration compressor is
operating are counted)
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.
h.
Push Set/Run button to exit program mode
NOTE: If Set Mode is not exited after 30 seconds, Alarm light
will illuminate and TIME OUT will appear on the interface panel.
Dryer will resume previous operating mode.
IMPORTANT: Energize dryer disconnect switch (provided
by others, sec NEC) 24 hours before refrigeration
compressor is started! Never use the disconnect switch
to shut-down the dryer for a extended period of time
(except for repair). Failure to follow these instructions
may result in a non-warrantable compressor failure.
