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 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 recom-
mended 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.
Dispensing compressed flake “nugget” ice in Servend dispensers takes special handling. Most dispensers require
special bin components and a universal ice management kit. Contact MBE regarding details for your installation.
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 agitation 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 beverage valve.
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.
115V/220V NON ADJUSTABLE AGITATION TIMER
The agitation timer on this unit is equipped with test pins. This allows you to test the timer by removing the jumper
between the two pins. When the jumper is removed the timer will cycle every 55 seconds if it is operating correctly. If the
timer is wired correctly and does not cycle approximately every 55 seconds when the jumper is removed, replacement
of the timer may be necessary. Make sure to replace the jumper pins when finished.
NOTES: This timer is re-settable, timed agitation every 3.5 hours from last dispense on power supply broken. Never
operate in normal mode without test pins in place, damage could occur.
