10.3 Resetting or Modifying the Service Required Warning (Sr)
Every 6000 hours the dryer will display the “Sr” (Service Required) warning. The dryer will continue to

dryer is maintained in accordance with the maintenance schedule outlined in Section 10.1.

Menu. The display will show you are at Parameter “A1”.
2) Press the Down button repeatedly to scroll down to Parameter “B3”.
3) Press Enter to access this parameter. The display will show you it’s value is “no”.
(The value cannot be changed by pressing the Up or Down buttons.)

a moment and then change back to “no”. The alarm has now been reset.

Please Note:
The purpose of the “Service Required” warning is to ensure proper maintenance
in accordance with the recommendations of the User Guide.
For this reason, pressing Alarm Reset will only reset the warning for 24 hours,
and parameters B3 (Reset Service Required Warning) and B9 (Service Required Warning Interval)
are locked - their values cannot be changed by pushing the Up and Down buttons.
Changing these parameters is a choice to ignore the supplier’s preventative maintenance
recommendations. This may lead to compromised performance, higher operating costs,
and eventual failure of the equipment.
For this reason, the procedures presented below are intended
ONLY for authorized factory and distributor service technicians.
