condenser.
Slow production

the room is hot or air flow restricted, production will be
slow.
Ice is poorly formed
. Check spray. If some spray jets
are restricted, ice will be poorly formed. Clean water
system to correct.
Note: In areas where the water supply has a high
mineral content, the spray jets may need frequent
clearing. Increasing the harvest time will flush
more water and help to reduce the frequency of
cleaning.
To increase harvest time:
1.
Confirm unit is in ice making mode. If the bin is
full and the unit is off the controller cannot be
adjusted.
2. Remove the front louvered panel.
3. Increase the time by pushing the + sign on the
harvest time adjustment section of the control
panel. Each push increases the time.
4. Return the front louvered panel to its normal
position.
