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.

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.

B-I-B
The Bag-In-Box system refers to a plastic disposable bag. The B-I-B normally contains 5 gallons of syrup, however
some locations offer 2 1/2 or 3 gallon B-I-B units. This plastic bag is then held inside a cardboard or other container.
B-I-B systems are for post-mix applications only.
PUMPS
The syrup in a B-I-B system is delivered to the beverage system through gas operated pumps. These pumps
extract the syrup out of the bags forcing the syrup throughout the system.
AUTO BAG SELECTORS
These are used on higher volume B-I-B systems where two or more bags of the same product are connected to
one pump and one system. An auto bag selector is essentially a valve that automatically changes from one bag (or
series of bags) to another bag (or series of bags) of syrup as the bags empty, allowing a constant flow of product.

Installation and Service Manual
OPERATION
Your syrup location can vary depending on the volume of beverages served and ease of accessibility. Your beverage system may set in a back storage room. Configurations are almost limitless. Check the temperatures expected
for the storage location. Adverse temperatures can affect the storage and quality of beverage products. It is recommended the temperature of storage location should not fall below 40o F or rise above 90o F.

OPERATION
CARBONATION
The purpose of the carbonator is to take regular tap water at street water pressure (minimum 40 PSI dynamic or
flowing pressure) 3/8” water line, and increase the water to beverage system pressure (usually 75 PSI). This water
is then combined with the CO2 gas. Chilling the mixture before dispensing will assist in locking the carbon dioxide
into the water. After dispensing, the CO2 may be unlocked from the liquid. The CO2 will gradually leave the liquid
due to pressure and temperature changes.
Components
The components of the carbonator are: water pump, an
electric motor to operate the pump, carbonator tank
where the water & CO2 mix, and a water level control.
Operation
Carbon Dioxide (CO2) leaves the storage tank and arrives at the carbonator tank through the gas inlet. Water
supply enters the carbonator pump inlet at regular street
water line pressure (minimum 40 PSI dynamic or flowing pressure). The water pump increases the pressure
of the water, which allows the water to flow into the carbonator tank. The CO2 and the water mix together in the
carbonator to produce the carbonated water that is then
sent to the tank soda dispenser.
The agitation of the water & CO2 together in the tank
under high pressure creates the carbonated water. The
quality of carbonation (percent of CO2 mixed in the water) increases as the water temperature decreases and
exposure time increases.
The water level in the carbonator tank is controlled by a
water level control in the tank. This control turns the pump
motor off and on to maintain a preset level of liquid in the
tank. The water level control is two conductivity probes
wired to a liquid level control board.
INTERNAL CARBONATION
The carbonator tank has two inlets and one outlet connection, as well as a relief valve and two conductivity
probes. The water inlet is topped by a 3/8" male flared
fitting. The carbonator will be pre-plumbed as it leaves
the factory. If the carbonator needs to be serviced or if
the fittings need to be replaced, make sure a nylon
washer is used inside each inlet fitting to prevent leaks.
The conductivity probes are used to control the level of
water inside the carbonator tank. The red probe, or the
“high” probe, is the shorter of the two. When the level
of the water reaches the bottom of the red probe, the
pump shuts off. The pump starts when the water level
inside the tank goes below the bottom tip of the of the
black or "low" probe. Both probes are wired to the elec-

tronic liquid level control, which is a circuit board
mounted inside the electrical box that activates the
pump and motor. Removing the cover of the electrical
box will grant access to the circuit board. As the control
receives a signal from the conductivity probes, it activates the pump motor, which will pump water into the
carbonator until the water reaches the high probe.
The pump is a standard 125 GPH brass rotary vane
pump. The flared fittings accept the same swivel/barb
connectors used on the carbonator water connections.
Also, water enters the pump from the water source on

BEVERAGE SYSTEM CLEANING
Sanitize the beverage system at initial start-up as well as during regularly scheduled cleaning. The drain pan must
be in place under soda valves, to carry away detergent and sanitizing agents that will be flushed through valves.
BAG-IN-BOX SYSTEM
The procedure below is for the sanitation of one syrup circuit at a time. Repeat to sanitize additional circuits.
You will need the following items to clean and sanitize
the Bag-in-Box (BIB) beverage system:
• Three (3) clean buckets
• Plastic brush or soft cloth
• Mild detergent
• Unscented bleach (5% Na CL O) or
Commercial sanitizer
• Bag-In-Box bag connector
1. Prepare the following in the buckets:
• Bucket 1 - warm to hot tap water for rinsing.
• Bucket 2 - mild detergent and warm to hot water.
• Bucket 3 - mix a solution of unscented bleach
(5% Na CL O) or commercial sanitizer and warm
to hot water. Mixture should supply 100 PPM available chlorine (1/4 oz. bleach to 1 gallon water).
2. Disconnect the “syrup-line side” of the bag-in-box
connector.
3. Rinse connector with warm tap water.
4. Connect syrup connector to BIB connector and immerse both into Bucket 1. A “bag-side” connector
can be created by cutting the connector from an
empty disposable syrup bag.
5. Draw rinse water through system until clean water
is dispensed. Most beverage valves allow the syrup
side to be manually activated by depressing the
syrup pallet.
6. Connect Bucket 2 to system.
7. Draw detergent solution through system until solution is dispensed.
8. Repeat steps 2-7 until all syrup circuits contain detergent solution.
9. Allow detergent solution to remain in the system for
5 minutes.

10. Connect Bucket 3 to system.
11. Draw sanitizing solution through system until solution is dispensed.
12. Repeat step 11 until all syrup circuits contain sanitizer solution.
13. Allow sanitizer solution to remain in system for 15
minutes.
14. Remove nozzles and diffusers from beverage valves.
15. Scrub nozzles, diffusers and all removable valve
parts (except electrical parts) with a plastic brush
or a soft cloth and the detergent solution.
16. Soak nozzles, diffusers and removable valve parts
(except electrical parts) in sanitizer for 15 minutes.
17. Replace nozzles, diffusers and valve parts.
18. Connect Bucket 1 to system.
19. Draw rinse water through system until no presence
of sanitizer is detected.
20. Attach syrup connectors to BIB’s.
21. Draw syrup through system until only syrup is dispensed.
22. Discard first 2 drinks.
PREVENTATIVE MAINTENANCE
Preventative maintenance is a vital part of keeping your dispenser in top condition. Following the guidelines below
will assist you in continued trouble free operation of your unit.
1. Conduct daily maintenance of the machine.
2. Perform monthly maintenance of the machine.
3. Perform periodic maintenance and sanitizing of beverage system.
4. Do not overfill the dispenser bin with ice.
5. Do not allow the dispenser to sit for prolonged periods of non use with ice in the bin.
6. Most ice dispenser service problems are caused by
low usage of the ice dispenser.
7. Do not allow ice to remain in the bin more than a day
in order to prevent ice from freezing together and/or
stagnant ice.
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.
