Storage Bin
Q0600C/Q0800C/Q1000C Ice Machines:
A stacking kit is required for stacking two ice machines.
Installation instructions are supplied with the stacking kit.
IB0600C/IB0800C/IB1000C/Q1400C/QDUAL:
Ice Beverage, Q1400C and QDUAL ice machines
cannot be stacked. However an adapter is available that
allows two Q1400C or QDUALC ice machines to be
placed side by side on a 60” Manitowoc F style bin.
Securing the Ice Machine to the Dispenser
IB0600C/IB0800C/IB1000C Only
Important
Manitowoc Ice/Beverage Ice Machines require an
adapter for mounting. Adapters are not included
with the ice machine, dispenser or bin and must be
ordered separately. When a non-Manitowoc adapter
is used, verify the adapter is compatible with
Manitowoc Ice/Beverage Ice Machines prior to
installation.
Standard with IB ice machines and packaged in head
section is the dispenser thermostat kit, K-00209. It is
required that this kit be installed with all IB ice machines.
The thermostat kit must be installed before the adapter
and ice machine head section is installed.
The purpose of the thermostat kit is to reduce machine
overfill and condensation problems in high humidity
locations. It is recommended that bin level control be
used on all dispenser applications with timed agitation to
allow for better agitation in the bin.
The ice machine and adapter plate must be secured to
the dispenser to prevent tipping.
• Two holes are located in the front bottom rail of the
ice machine, to allow attachment to the adapter
plate.
• The adapter cover must be secured to the dispenser
to prevent ice from dislodging the cover during
agitation.

Connect The Line Set To The Ice Machine Head
Section
!
Warning
The ice machine head section contains refrigerant
charge. The ice machine head section contains three
(3) refrigeration valves that must remain closed until
proper installation of the line sets is completed.
The line set shut off valves at the back of the ice
machine must remain closed and be protected from heat
during the brazing process. Wrap the valves in a wet rag
or other type of heat sink prior to brazing. Cool braze
joint with water immediately after brazing to prevent heat
migration to the valve.
Connect The Line Set To The CVD Condensing Unit
The compressor oil rapidly absorbs moisture. Be
prepared to complete line set installation and start your
evacuation process in order to minimize the time the
compressor is exposed to the atmosphere. (Maximum
amount of time the system can be exposed to the
atmosphere is 15 minutes). The line set can be routed
for entry through the front or left side of the condensing
unit.
• Remove knockout for preferred location.
• Insert supplied plastic bushings in knockout holes to
prevent tubing from contacting sheet metal.
• Use the supplied 90° elbows to route tubing.
