Start-Up Procedure
Before starting the machine, make sure the machine is level within 1/8 inch in all directions, the bin or dispenser leg
height can be adjusted by rotating the leg foot.
Check the water level in the water trough. It should be approximately ½ inch above the top of the water pump impeller
housing. The water level can be adjusted by bending the float arm.
Move the ICE-OFF-WASH switch to the ICE position. The switch is located in the control box. Remove the ice machine
front panel or remove the lower grill on the under counter models to access the control box.
Check for proper water flow over the evaporator(s). There should be an even flow of water over the evaporator(s).
Check the water regulating valve (water cooled machine) for proper adjustment by measuring the water temperature at
the outlet of the condenser. It should be between 100
°F and 110°F (38°C and 43°C). Adjust the water regulating
valve as required.
As ice begins to form on the evaporators, check the freeze pattern of the ice. Ice should form evenly across the
evaporator. Models CCM0830, CCM1030, CCM1848 and CCM2148 machines will have a slight variance from the top
to the bottom of the evaporator(s).
Bridge Thickness and Timer Adjustment
Once the ice drops off the evaporator(s) during harvest, check the bridge thickness of the ice slab. The bridge should
be 3/16 of an inch on Undercounter and CCM0330 units. The bridge should be 1/8 of an inch on all other units. If the
bridge thickness is incorrect, the timer will need adjustment.
The ice bridge thickness is controlled by the freeze timer located in the control box. To check the timer setting, add the
seconds of each dipswitch turned to the “ON” position. The number beside the each dipswitch represents seconds.
To increase the bridge thickness, increase the timer setting. To decrease the bridge thickness, decrease the timer
setting. The freeze timer can be adjusted by sliding one or more switches to either the “ON” or “OFF” position to
obtain the desired setting.
Note: The right hand timer on the CCM1448, CCM1848 and CCM2148 units should be set at 4 seconds only,
do not adjust this timer.
