dispenser.
The HD356 has been designed to work with
Scotsman’s CME256, CME506 or CME656. It may
also be used with a CME865 or CME1002. If using
on a prior model, such as CM250 or CME500, an
adapter kit, KBTCD200 must be ordered.

Ice Machine
All models: Place the dispenser in the location
where it will be used. Level the top edge of the
dispenser front to back and left to right.
CME256, CME506, CME656, CME865 or
CME1002:
Place the ice machine on the dispenser and
secure it to the dispenser with the hardware and
straps from the ice machine.
Install it according to the instructions in the manual
included with the ice machine.
Prior Ice Machine Models:
Prior Scotsman ice machines
used a thermostat as a bin
control device. There is no
provision for mounting that
thermostat in the standard
HD356.
To use a thermostat with the
HD356, install kit KBTCD200
wand use its thermostat
bracket. Place the ice machine
on the dispenser and route the
ice machine’s bin thermostat
capillary tube into the bin
thermostat bracket of the
dispenser.
Re-install the ice machine
according to the instructions for
that model.

Utility Connections
As ice melts in the dispenser the water must be
drained away. It is critical that a proper drain be
connected to the dispenser. Remember that this is
a gravity drain system - tubing must slope down a
minimum of ¼" per foot of horizontal run.
Follow all applicable codes.
Usually an air gap must be established between
the end of the drain tube and the building’s drain
receptacle.
The dispenser’s drain must be separate from
the drain used by the ice
machine.
•Use only rigid tubing.
•Install a vent at the ice
machine’s reservoir
drain AND the
dispenser’s drain.
Failure to vent the
drains may result in
water backup.
Electrical:
There is a junction box on the back of the machine,
connect the power supply to the wires inside the
junction box.
Follow all applicable codes.
Be certain that the ice machine AND dispenser are
grounded.

Initial Start Up & Use
Final Check List
1. Is the ice machine properly installed?
2. Is the dispenser level?
3. Has the water supply been connected to the ice
machine?
4. Has the proper electrical power been connected
to both the ice machine and the dispenser?
Note: When electrical power is supplied to the
dispenser the rotor will rotate slightly.
5. Have the drain lines been connected and are
they separate from the ice machine?
Initial Start Up
1. Locate key and unlock the sink.
2. Remove sink.
3. Locate on-off switch, move it to the ON position.
4. Return sink to its
original position.
5. Simulate a vend.
The rotor should move
1/6 of a revolution on
push button machines
and a full revolution on
coin vending
machines.
6. Record the ice machine model
and serial number on the last page
of this manual and on the warranty
registration form.
Mail the form to Scotsman
Operational Note: Every 6 hours the rotor will
be activated to agitate the ice. This may result
in some ice in the chute.

Sanitation and Maintenance
Schedule:
An ice system represents a sizable investment of time and money in any company’s business. In order to
receive the best return on that investment, periodic maintenance is required.
It is the user’s responsibility to see that the machine is properly maintained. Maintenance and Cleaning
should be done a minimum of twice per year, and more if the ice machine is operating in a dusty area.
Monthly:
Unlock sink and remove it. Then pull out the removable upper drain chute. Clean out any debris that may
have accumulated in it.
Check the lower drain pan for debris, remove any and pour one quart of an approved sanitizing solution
into the drain pan. Flush with warm water.
Return the upper drain pan and sink to their original positions.
Ice Machine: Follow the instructions in the ice machine service manual.
Dispenser: The only maintenance required is the periodic cleaning of the drain pans, screens and
sanitizing the bin.
Sanitizing
1. Vend all ice out of the machine.
2. Remove the ice machine’s front panel and
switch it to OFF.
Note: This would be a convenient time to clean
and sanitize the ice machine.
3. Disconnect electrical power to the dispenser
and ice machine.
4. Remove the sink and hopper assembly by
unlocking it at the base.
5. Remove two screws at the back connecting the
ice machine to the dispenser.
6. Push the ice machine back 5 ½ “
7. Reach in the hopper and locate the nut holding
the rotor to its drive shaft. Unscrew the nut and
remove the metal parts.
8. Push the rotor back off its drive shaft. Pull the
rotor out of the dispenser.
9. Mix a cleaning solution of 8 ounces of Scotsman
Ice Machine Cleaner and 3 quarts of warm (95oF
to 115oF.) potable water.
10. Scrub the interior of the dispenser’s hopper
and the rotor with the cleaning solution.
11. Scrub the metal parts removed in step 7 with
the cleaning solution.
12. Scrub the inside of the ice chute with a clean
cloth and the cleaning solution.
13. Mix two gallons of approved sanitizing solution,
one possible solution is one ounce of household
bleach to two gallons of warm (95oFto115
oF.)
potable water.
14. Thoroughly wash the inside of the dispenser’s
hopper, including the shaft and all sides of the rotor
with the sanitizing solution.
15. Thoroughly wash the inside of the ice chute with
the sanitizing solution.
16. Thoroughly wash the metal parts and the nut
removed in step 6 with the sanitizing solution.
17. Reassemble rotor to shaft, return metal parts to
rotor and secure with nut.
18. Return the ice machine, all panels, covers and
the sink assembly to their original positions.
19. Resecure the ice machine to the dispenser.
20. Reconnect power and switch the ice machine
on.

Adjustments: For Service Technicians
The gear motor cam must be properly adjusted to
properly position the dispensing rotor.
1. Disconnect electrical power to the dispenser.
2. Locate sink key, unlock sink and remove it from
the dispenser.

opening.
5. Loosen the cam on the shaft and rotate it until
the cam switch follower drops into the lowest part of
the cam.
