Installation Instructions

General

These instructions are provided to assist the qualified

installer. Check your local Yellow Pages for the name of

the nearest Manitowoc distributor, or call Manitowoc

Foodservice for information regarding start-up services.

Please contact you local Manitowoc Distributor or call

Manitowoc Foodservice for assistance if you encounter

a problem that is not covered by this manual.

Electrical Service

GENERAL

Line voltage is obtained from the ice machine. Refer to

the Model/Serial plate on the ice machine and 

AuCS® to verify both voltages are the same.

AuCS® Installation

LOCATION / MOUNTING

The location selected must meet the following criteria. If

any of these criteria are not met, select another location.

• The location must be free of airborne and other

contaminants.

• The air temperature must be at least 40°F (4°C), but

must not exceed 110°F (43°C).

• The location must not be near heat-generating

equipment or in direct sunlight.

Important

Failure to follow these installation guidelines may

affect warranty coverage. Improper installation will

affect dispensing rate. Install only within the

parameters outlined in this installation manual.

Warning

A trained and qualified technician must install the

AuCS®.

Voltage Phase Cycle Amperage

115/1/60 0.3

208-230/1/60 0.1

Warning

All wiring must conform to local, state and national

codes.

Warning

The ice machine and AuCS® must be grounded in

accordance with national and local electrical codes.

Important

Observe correct polarity of incoming line voltage.

Caution

The AuCS® accessory must be protected if it will be

subjected to temperatures below 32°F (0°C).

Failure caused by exposure to freezing

temperatures is not covered by the warranty. See

“Removal from Service/Winterization”.

Installation Instructions Section 2

6Part Number 000009036 3/12

HEIGHT REQUIREMENT

Either the base or the top of the AuCS® accessory must

be within 2" (5 cm) of the base of the ice machine. Do

not mount the AuCS® unit too high or too low.

DISTANCE REQUIREMENT

The AuCS® unit must be mounted within 9 feet (2.7 m)

of the ice machine to accommodate the low voltage

communication wire and tubing. The tubing may be

shortened to accommodate a run of less than 9 feet

(2.7 m).

MOUNTING

Parts

Mounting to Bin or Dispenser

NOTE: The ice machine’s serviceability may be reduced

when the AuCS® unit is mounted to the bin ordispenser.

Wall mounting is recommended.

1. Set the mounting bracket over the bin top rail at

desired location.

2. Remove the backing from the foam adhesive tape.

Apply tape to mounting bracket, and along the entire

bin rail.

3. Align the AuCS® key slots with the mounting

bracket tabs. Verify the tabs are at the top of the key

slots and that the AuCS® unit is level.

Caution

The cleaner or sanitizer may siphon (or dispense

improperly) into the ice machine water trough if the

AuCS® unit is mounted too high or too low.

Caution

Do not extend the length of the 9-foot (2.7 m) low

voltage communication wire or tubing. The correct

amount of solution will not dispense.

4. Remove the backing from the adhesive bumpers.

Attach bumpers to the mounting bracket directly

above the AuCS® control box. This eliminates

upward movement and stops the tabs from

disengaging the key slots.

Mounting to Ice Machine

Mounting to Wall

The AuCS® is mounted to the wall using the two key

slots in the back wall of the accessory. Screw fasteners

(not supplied) must hold the entire weight of the 

AuCS® (approximately 10 lbs. [4.5 kg]).

Key Slot Dimensions

CONNECTION TO ICE MACHINE

Electrical Connections

1. Check electrical code for your area.

• When local code allows, the included wire and strain

relief can be used for line voltage wiring. Remove

knockout from ice machine and install strain relief

and wire.

• When conduit is required remove strain relief and ice

machine electrical knockout. Install conduit as

required by your electrical code.

• Connections on ice machines vary. Refer to the

diagram for the ice machine you are working on.

2. Remove the front, top, and right side panels from the

ice machine.

3. Route line voltage wires through control box line

voltage heyco fitting. Connect line voltage wires to

incoming power supply of contactor and ground

screw.

NOTE: On QuietQube Ice Machines the power

connection is made at the incoming power supply (L1

and L2). Cut-off yellow terminal (L2) and purple terminal

(L1) on AuCS harness. Strip insulation back 1/2" and

connect.

Communication Wire and Vinyl Tubing

The communication wire and vinyl tubing must be

installed in conduit to protect them from damage.

1. Remove the 7/8" knockout hole plug located on the

back of the ice machine.

2. Install conduit from the AuCS® unit to the ice

machine. A pulling elbow is recommended for easier

routing of the vinyl tubing and modular wire.

3. Route low voltage communication wire and vinyl

tubing together through the conduit.

4. Route modular wire through control box low voltage

heyco fitting. Do not route with line voltage wiring,

erratic operation could result. Connect modular wire

to control board.

5. Connect the communication wire to the AuCS

control board.

Vinyl Tubing Connection

1. Remove the water trough.

A. Depress tabs on right and left side of the water

trough.
