ICE RECOMMENDED FOR DISPENSING
Servend 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 plus a universal ice management kit. Contact MBE regarding details for your particular
installation.
14
OPERATION
EQUIPMENT
Installation and Service Manual
The LP-3 is a 10 flavor ice and beverage dispenser, with
the ice storage bin located below the counter top level. A
drink tower extends 19” above the counter top level. The
LP-3 is designed to fit into a 42.5” wide by 30.38” deep
space, and can be counter mounted (like a conventional
drop-in unit), or arranged as a stand alone with cosmetic
stainless panels.
Within the 19” drink tower is an optional 1000 lb/day remote ice cube maker, especially designed by Manitowoc
for this application.
Beverage cooling is accomplished by means of a cold
plate positioned below the storage bin, and the unit can
include an internally mounted or externally mounted carbonator system. In order to allow any valve to dispense
carbonated or non-carbonated beverages, two Servend
Flex Manifolds are incorporated into the tower.
Ice is dispensed from the storage bin by means of the paddle
wheel into an auger which raises the ice to the top of the
tower where it is dispensed by means of a rocking chute.
The drink tower is enclosed by 5 panels, one on each
side and back, as well as a splash panel in front below
the valves, and a top panel. Safety switches will disable
the ice dispensing circuit when either the top panel or
the splash panel are removed. The drive motors for agitation and auger ice lifting are mounted using locking pins,
and thus can be removed for maintenance and cleaning
without tools. Access is provided for in place cleaning of
the ice maker. The ice maker water valve, water pan, curtain, and water pump can all be removed for service and
cleaning without removing the ice maker itself.
®
The LP-3 can be built in either a left hand or right hand ice
dispense arrangement. In the right hand configuration water/syrup lines from the BIB pumps are brought in to the
unit at the lower left, drains, electrical and refrigerant lines
on the right.
Drain hoses are provided for the waste water from the
cuber, spillage and melt water from the drain pan, and
melt water from the storage bin and auger. A water supply line is necessary for the ice maker and beverage system, each connecting to a 3/8” ID. beverage tube.

Installation and Service Manual
OPERATION
ICE STORAGE AND DISPENSING
Ice is stored in the dispenser’s bin. Ice below the stainless steel bin liner is used to cool the aluminum cold plate, at
the bottom of the ice dispenser bin. Ice above the stainless steel bin liner is dispensed into the customer’s cup.
Ice is transported from the bin to the ice dispense point by the paddle wheel and vertical auger. The injection
molded paddle wheel has paddles which push the ice into a vertical auger that carries it to the dispense point.
ICE AGITATION
The paddle wheel and auger carry ice. Periodic agitation is standard on the LP-3. During periodic agitation, the
paddle wheel, auger and agitator turn for approximately three seconds every hour. The door lock prevents ice from
being dispensed during the agitation cycle.
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 and
auger motor. The gear motor turns the paddle wheel and
agitator bar, the auger motor turns the auger.
ICE AUGER
Ice is pushed into the auger by the paddlewheel. The auger lifts the ice from the bottom of the bin to the ice
dispense point at the rocking chute.
COLD PLATE BEVERAGE COOLING
A cold plate is a block of aluminum with serpentine stainless steel tubes molded inside the aluminum block. The
cold plate is approximately the same length and width
as the bottom of the dispenser bin. Ice sits on top of the
cold plate and cools the cold plate.
The stainless steel tubes inside the cold plate carry carbonated water (soda water), noncarbonated water (plain
water) and syrup to the beverage valves. While flowing
through the stainless steel tubes in the cold plate, water
and syrup are chilled to serving temperature.
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.
