11 Routine Maintenance
1. Test Head Switch.
The head switch feature is designed to
prevent the beater shaft from being acci-
dentally activated. It is essential that the
proper operation of this switch be verified
on a routine basis. Use the following in-
structions to test for proper operation.
Check each side of the freezer using this
procedure.
1. Be sure all switches are in the
"OFF" position.
2. Disconnect the main power supply.
3. Remove the dispense head and
beater shaft assembly.
4. Connect the main power supply.
5. Turn the selector switch to the
"CLEAN" position.
6. Look inside the freezing cylinder
toward the rear, the drive shaft coupling
should NOT be turning. Turn the switch
"OFF" and disconnect the main power
supply.
7. If the drive shaft coupling is turning,
or you are unable to determine whether or
not the shaft is turning, turn the switch to
the "OFF" position, disconnect the main
power supply and contact your Electro
Freeze distributor for service. DO NOT
place the freezer in service until the prob-
lem has been fixed.
