Function check
Check that the drum is empty and the loading
door is closed.
Checking the micro switches
Start the dryer.
Check if the micro switches are working
properly:
• The dryer must stop if the loading door is
opened.
If the dryer operates with the loading door
open, go to section Door switch and filter
door switch.
• The dryer must stop when the filter door is
opened.
If the dryer operates with the filter door open,
go to section Door switch and filter door
switch.
Correct direction of rotation
For dryers with a 3-phase motor the direction of
rotation must be checked.
Correct direction of rotation must be clockwise,
fig. 1.
If the direction of rotation is not correct, swap
two phases on the power input connection
terminal block.
Final test
1. Start the dryer and allow it to operate for 5
minutes on a program with heat.
2. Check if the heating is working by opening
the loading door and feeling the heat.
If the above test-points have been carried out
and the dryer is operational, the dryer is ready
for use.
Note! Gas heating
To ensure the correct amount of air to
the combustion, plate A (fig. 2) must be
mounted before starting the dryer.
