Keep a record of all maintenance works and repairs.
Please note that electronic components can be damaged by static discharge.
Before initial operation and in regular intervals, make sure that no electrical connections are loo- se.
Never readjust sensors without exactly knowing their functions.
Please ensure that the permitted storage temperature lies between 0 and +55 °C (32 to +131 °F).
Please ensure that the permitted operation temperature lies between 0 and +45 °C (32 to +113 °F).
Check the direction of rotation of the blowers after the electrical connections have been made (see rotational direction arrow).
Clean the drying hoppers before the first filling.
Note the instructions of the material manufacturer for the maximum drying temperature.
Note the drying instructions of the material manufacturer.
Take care that the drying hoppers are always completely filled and that the retention period is re- spected if continual removal is taking place.
Note that too large amounts taken from the drying hopper lead to insufficient drying of the materi- al.
Close the air stop valves of drying hoppers which are empty or have not been used.
Note down all data which you have entered into the control system.
The password is to be entrusted to authorised personnel only.
Please note that the temperature of the dryer heating system must always be set lower than that of the supplementary heaters.
When you dispose of drying agents, observe all official rules.
Note that drying cells are replaced or refilled by Sterling only if they are empty.
The material level may not fall below 40 % in the drying hopper, when material is continuously re- moved from the drying hopper, but no material is continuously fed into the drying hopper (batch drying). Close the throttle valves.
Read the operating manuals of the connected devices.
