SAFETY
GROUNDING IN STRUCTIONS
WARNING: Risk of electrical shock. Connect to a properly grounded outlet only.
This appliance must be grounded. In the event of malfunction or breakdown, grounding provides
a path of least resistance for electric current to reduce the risk of electric shock. This appliance is
equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug
must be plugged into an appropriate outlet that is properly installed and grounded in accordance
with all local codes and ordinances.
DANGER – Improper connection of the equipment-grounding conductor can result in a risk of
electric shock. The conductor with insulation having an outer surface that is green with or without
yellow stripes is the equipment grounding conductor. If rep air or replacement of the cord or plug
is necessary , do not connect the equipment-grounding conductor to a live terminal. Check with a
qualified electrician or serviceman if the grounding instructions are not completely understood, or
if in doubt as to whether the appliance is properly grounded. Do not modify the plug provided with
the appliance – if it will not fit the outlet, have a proper outlet installed by a qualified electrician.
WARNING – When using electric appliances, basic precautions should always be followed, including the following:
a)Read all the instructions before using the appliance.
b)To reduce he risk of injury, close supervision is necessary when an appliance is used
near children.
c)Do not contact moving parts.
d)Only use attachments recommended or sold by the manufacturer.
e)Do not use outdoors.
f) For a cord-connected appliance, the following shall be included:
• Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
• Unplug from outlet when not in use and before servicing or cleaning.
• Do not operate any appliance with a damaged cord or plug, or after the appliance
malfunctions or is dropped or damaged in any manner. Return appliance to the
nearest authorized service facility for examination, repair , or electrical or mechanical
adjustment.
g)For a permanently connected appliance – Turn the power switch to the off position when
the appliance is not in use and before servicing or cleaning.
h)For an appliance with a replaceable lamp – always unplug before replacing the lamp.

NOTE: For full information about icemaker installation, including plumbing lines connections and electri-
cal requirements, see the icemaker installation manual.
ICE FLOW RESTRICTOR
For all MII, MD and MDH Series dispensers an Ice flow
restrictor is available. This ice flow restrictor decreases
the amount of ice allowed to enter the ice chute by blocking a small area at the entrance of the dispenser chute.

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 recommended for dispensing. “Super cooled” ice is ice that has been stored in freezers below 32oF. 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. Cont act 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.
1 15V/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.

Possible excess ice storage reasons:
• Storage capacity exceeds daily requirements.
• Low demand during the off season.
• Dispenser oversized with future growth in mind.
Lower ice storage to meet one day’s needs. If you manually fill ice, fill only with the appropriate amount of ice. Fill
the dispenser with fresh ice each morning. Do not fill the
dispenser at night just before shut down. Ice cubes can
freeze together if not dispensed.
