OPERATION
UNIT INSPECTION
Thoroughly inspect the unit upon delivery. Immediately report any damage that occurred during transportation to
the delivery carrier. Request a written inspection report from a claims inspector to document any necessary claim.
ICE STORAGE AND DISPENSING
As the customer presses the rocking chute, the arm at the top left rear of the chute pushes upward on the door lock.
The door opens until it contacts the stops in the mounting brackets. The plastic arm on the ice chute also activates
the lever of the ice dispensing switch. When activated, the micro switch starts the gear motor. The gear motor turns
the paddle wheel and agitator arm.
The paddlewheel carries ice. Periodic agitation is optional on the MII-150 and MII-175 and is standard on the MII-
200, MII-250, MII-302 and MII-402. During periodic agitation, the paddle wheel and agitator turn for approximately
three seconds every three and one half-hours. The door lock prevents ice from being dispensed during the agita-
tion cycle.
BEVERAGE VALVES
Post-mix beverage valves are designed to precisely meter the flow of both water and syrup to obtain the proper
mixing ratio. The syrup and soda water components of the post-mix beverage are mixed as they leave the bever-
age valve.
ROCKING CHUTE ICE DISPENSING
As the customer presses the rocking chute, the arm at the top left rear of the chute pushes upward on the door lock.
The door opens until it contacts the stops in the mounting brackets. The plastic arm on the ice chute also activates
the lever of the ice dispensing switch. When activated, the micro switch starts the gear motor. The gear motor turns
the paddle wheel and agitator bar.
LEGS
Legs are optional equipment with most MBE dispensers. Standard legs are four-inch (10.2 cm) tall stainless steel
legs. MII 302 and MII 402 cannot be placed on legs. When installing legs on a MII Series dispenser, leg braces
should be used. These are metal braces fitting side to side under the dispenser that reinforce the leg attachment
area. It is recommended if an icemaker is installed on top of the dispenser, legs should not be installed.
ICE RECOMENDED FOR DISPENSING
MII dispensers are designed to dispense hard, cube ice up to one-inch square. The ice shapes and sizes listed
above are recommended for dispensing. Warm “Super Cooled” Ice Before Dispensing “Super Cooled” ice is
not recommended for dispensing. “Super cooled” ice is ice that has been stored in freezers below 32
o
F. Should
it be necessary to temporarily use “super cooled” ice, allow the ice to warm at room temperature for 25 to 30
minutes before placing the ice in the dispenser.
