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]).

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.

1. Remove the water trough.
A. Depress tabs on right and left side of the water
trough.
B. Allow front of water trough to drop as you pull
forward to disengage the rear pins.
2. Locate the water inlet tube on the right hand side
(see below) of the ice machine base. Directly to the
left of the tube there is a small plug that must be
