5.3.2 Checking the direction of rotation of the motor
Check whether the electrical motor's direction of rotation is correct by
proceeding as follows:
Item Designation
1 “Power supply ON – OFF” main switch
2 “Reverse pump” illuminated push-button
▶
Switch the machine on at the main switch.
➙
The machine performs an automatic rotating field test.
A lamp test is carried out first after actuating the main switch. If the
“Reverse pump” illuminated push-button lights up briefly, this indi‐
cates that the direction of rotation is correct.
If the direction of rotation is incorrect, the indicator lamp in the illu‐
minated push-button will stay lit. The direction of rotation of the
motor must be changed.
