BAFFLE FOR MANITOWOC® ICE MACHINE

When installing a Manitowoc Ice Machine on a

dispenser, a baffle kit is required for proper installation.

The baffle kit is designed to prevent ice from lying

against the front of the ice machine, and melting down

the front of the dispenser. There are two different baffle

kits available for “S” series ice machines, one kit is for

the 30" wide machine, and the other kit is for the 22"

wide machine. There is also a kit for “Q” series ice

machines.

Kits are available through your local distributor. List

prices may be subject to change without notification.

Please call your local parts distributor for current pricing

before ordering.

MANUAL FILL LID FOR DISPENSERS

WITH AN ICE MACHINE

If you are top mounting your dispenser with a ice

machine, you will require a lid for the manual fill area at

the top, front of the dispenser.

If you ordered a dispenser and a ice machine at the

same time, the manual fill lid was included with the unit.

The manual fill lid can be ordered from your local

distributor.

Location

The location selected for the beverage dispenser must

meet the following criteria. If any of these criteria are not

met, select another location.

• The air temperature must be at least 50°F (10°C), but

must not exceed 95°F (35°C).

• The location must not be near heat-generating

equipment or in direct sunlight and must be protected

from weather.

• The countertop must be level. Verify that the

countertop can support the weight of the dispenser,

or the dispenser/ice machine combination plus the

weight of the stored ice.

• Water lines, drains and power outlet must be within 6'

(1.8 m) of location.

Location Requirements for Top Mounted Ice

Machine Installations

Location — Avoid placing the dispenser and/or ice

machine near heat sources such as radiators, ovens,

refrigeration equipment and direct sunlight.

Clearances — Refer to the ice machine installation

manual for clearances.

Front of ice machine to be flush with front of

dispenser — Some ice machines may overhang at the

back of the dispenser.

Drains — A separate drain line is required for the ice

machine, in addition to a drain line for the ice/beverage

dispenser.

Dispensers may require an adapter kit to install some

top-mounted ice machines. Contact your local distributor

for the correct adapter kit.

For full information about ice machine installation,

including clearances, plumbing lines, connections,

and electrical requirements, see the ice machine

installation manual.

Warning

Carbon Dioxide (CO

) displaces oxygen. Exposure

to a high concentration of CO

gas causes tremors,

which are followed rapidly by loss of consciousness

and suffocation. If a CO

gas leak is suspected,

particularly in a small area, immediately ventilate the

area before repairing the leak. CO

lines and pumps

must not be installed in an enclosed space. An

enclosed space can be a cooler or small room or

closet. This may include convenience stores with

glass door self serve coolers. If you suspect CO

may build up in an area, venting of the B-I-B pumps

and / or CO

monitors must be utilized.

GENERAL

MINIMUM CIRCUIT AMPACITY

The minimum circuit ampacity is used to help select the

wire size of the electrical supply. (Minimum circuit

ampacity is not the beverage/ice machine’s running amp

load.) The wire size (or gauge) is also dependent upon

location, materials used, length of run, etc., so it must be

determined by a qualified electrician.

ELECTRICAL REQUIREMENTS

Refer to Ice Machine Model/Serial Plate for voltage/

amperage specifications.

VOLTAGE

The standard voltage for MDH Series dispensers is

120VAC-60Hz. A power cord is provided with 120VAC-

60Hz models only. MDH Series dispensers use a 1/7 hp

gearmotor.

MINIMUM CIRCUIT AMPERAGE CHART

Grounding Instructions

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.

Warning

Risk of electrical shock. Connect to a properly

grounded outlet only.

Warning

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 repair 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.

Water Supply

RECOMMENDED PLUMBING

The plumbing diagram is printed on a white vinyl label,

normally located above the inlet tubes for syrup and

water. The plumbing diagram label can be accessed by

removing the splash panel of the dispenser. The

plumbing diagram label explains which inlet coldplate

fittings supply which dispenser valves and water

manifolds.

The water supply must first be connected to the

carbonator pump (not shown) before plumbing to

connection “A” shown on plumbing diagram. The

carbonator pump deck must be within six feet of the

dispenser for optimum performance. See BIB installation

diagram for system pressure settings.

A check valve must be installed in the water supply

line 3 feet from the noncarbonated water connection

“PW”. Contact factory if not installed.
