Introduction
To the owner or user: This product manual is a
source of information about the installation, start
up, cleaning, maintenance and repair of the
product.
The HD156 is a hotel/motel ice dispenser. It is
designed to use a Scotsman CME306 or CME456
ice machine as the source for ice.
Ice from the cuber falls into the insulated hopper,
where it is stored until needed. When a user
pushes the dispense button a rotating wheel
scoops the ice up to the top front of the hopper
where there is an outlet to the ice chute.

Installation: General
After the carton has been removed from the
dispenser, the legs may be installed.
Place flat portions of the carton on the floor behind
the dispenser and lay the dispenser down on its
back.
Thread the legs into the base of the dispenser. Be
sure that the legs are screwed in all the way. Turn
the leg levelers in all the way.
Move the dispenser to an upright position and set it
in the location where it will be installed. Note where
drain lines and electrical connections will be made.
Drain:
The dispenser has a 3/4" FPT drain fitting at the
bottom center of the back panel. Connect 3/4" rigid
tubing to this connection, a vent is recommended
for most installations. Route the drain tubing to the
building drain. Follow all applicable plumbing
codes.
HD156
Note
Remove any packing material from inside the
storage bin. Retain keys for later use.
Check that gasket tape is on the top outside edge of
the dispenser where the ice machine will rest.
Because the drain tubing will be very cold,
insulation is recommenced.
Electrical:
There is an electrical junction box on the lower
back panel
Make the electrical connections there. Follow all
applicable electrical codes. Use a licensed
electrician.
The dispenser must be installed so that it is a
separate piece of equipment from the ice machine.
The drains and electrical supply must be separate.

Installation: Ice Machine
Check that gasket tape has been placed at the
outside edge of the dispenser top.
There is no thermostat to install. Place the ice
machine (CME306 or CME456) onto the top of the
HD156. The ice machine will sense when ice builds
up into its cube port and shut off. It automatically
restarts when that ice is removed.
Follow all instructions for installation of the ice
machine.

installed per the ice machines installation
directions.
4. Check that the ice machine/dispenser assembly
is level front to back and left to right.
5. Check that optional kits, if any, have been
correctly installed.
6. Check that the sink key, and coin box key if

Electrical Sequence
Pushing the vend button closes a contact to the
gear motor and to the ice door solenoid.
The gearmotor and ice door solenoid will have
power and the dispenser will continue to operate
as long as the dispense switch is pushed in. This
model also has a agitation cycle of 3 seconds
