Installation and User’s Manual
Introduction
The ice maker-dispensers covered in this manual
were designed by to be the nest on the market. Their
design is a result of Scotsman’s long experience in ice
maker-dispensers.
This manual includes the information needed to
install, start up and operate the machine. Because
there are three models covered, be sure that any
instructions apply to your unit.
HID312 is 16 inches wide and air cooled only.
HID525 is 21 inches wide and 34.9 inches tall. it is
available as an air cooled model or as a water cooled
model.
HID540 is also 21 inches wide, but it is 40.9 inches
tall. it is also available either air or water cooled.

Installation and User’s Manual
Placement
The location of the equipment should be selected
with care. Consideration should be given to allow
adequate space on the sides for air cooled models to
breathe.
Minimum clearances for air cooled models:
• 6 inches at each side
• 2 inches above, 10” more to allow auger removal
when ceiling is xed.
• 6 inches at the back.
Air cooled models ow air left to right. More space
than the minimum at the sides will maximize
performance.
Cafeteria applications.
The unit can be placed in a cafeteria line for ice and
water. As some users sometimes dispense too much
ice, high volume use may require the drip tray to be
occasionally cleared of spilled ice.
Unpack
1. Separate the carton from the shipping pallet.
2. Remove any strapping holding the cabinet to the
pallet.
3. Inspect for hidden shipping damage. If any is
found, retain carton and notify carrier for potential
claim. Shipping damage is not covered by
warranty.
4. Remove bolts holding machine to pallet. Use
caution to not tip unit too far when removing bolts.
Airow Direction
The power outlet should be located within the length
of the supplied power cord. If placed on a counter,
the counter must be strong enough to support the
weight of the unit. Space above the cabinet should be
allowed for service and maintenance. If legs will be
used, allow space for the total cabinet height.
Air cooled models in a small room will require
ventilation to exhaust the heat they produce. They
also produce some added noise from the fan.
Noise sensitive areas should consider water cooled
equipment or the machine located where the noise
from ice making is not objectionable.
Nearby infrared emitters or a window that allows
sunlight to shine on a dispensing sensor may cause
the unit to dispense ice or water without a container to
trigger it.

Unpacking
5. Remove plastic covering the drip tray.
6. Remove the protective plastic covering the panels.
The longer it is left on the panel, the harder it will
be to remove it.
7. Place unit on machine stand or on counter. If on
machine stand secure the cabinet to the machine
stand with the required fasteners.

Installation and User’s Manual
Counter Installations
Units placed on a counter must either use legs or be
sealed to the counter top with food grade sealant per
local codes. To avoid disturbing the seal, complete the
installation prior to sealing.
Note: Seal
Chassis to
Counter, do NOT
Seal Drip Tray
Legs
Panel Removal
Remove one screw at bottom front of upper front
panel, swing bottom of panel forward and lift off the
unit.
4” legs are optional for countertop applications. They
are not to be used on the HID dispenser when it is
placed on a machine stand.
Note: Use
only legs of 4”
minimum height.
Set Up
The drip tray and cup rest are shipped in place, there
is no need to attach or remove them. It is a good idea
to remove the front panels and inspect for any loose
or rubbing parts prior to installation.

Twist ice and
water chutes
counterclockwise and
pull down to remove.
Remove four screws
from sides of lower

slightly and rest it
on the drip tray. If
needed, unplug sensor
connector and separate
panel from unit.
Pre-Start Inspection
Level the cabinet front to back and left to right.
Conrm there are no loose or rubbing parts.
Return splash panel and chutes to unit.
