OWNERSHIP
TO INSURE THAT YOUR UNIT WORKS PROPERLY
FROM THE FIRST DAY, IT MUST BE INSTALLED
PROPERLY.
NOTE: WE HIGHLY RECOMMEND A TRAINED
INSTALLER, PLUMBER OR ELECTRICIAN INSTALL
YOUR TRUE RESIDENTIAL®ICE MACHINE. THE
COST OF A PROFESSIONAL INSTALLATION IS
MONEY WELL SPENT.
Before you start to install your True Residential®Ice
Machine, carefully inspect it for freight damage. If
damage is discovered, immediately file a claim with
the delivery freight carrier. True is not responsible for
damage incurred during shipment.
Any questions about the installation please
contact your True dealer or True Technical Service
Department at 844-746-9423. Please have your

Service Department.
SAFETY PRECAUTIONS
• This ice machine must be properly installed
and located in accordance with the installation
instructions before it is used.
• Do not allow children to climb, stand or hang
on the ice machine. They could damage the ice
machine and seriously injure themselves.
• Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any
other appliance.
• Keep hands away from the “pinch point” areas and
gaps between the doors and cabinet. Small areas
are not necessarily safe.
• Unplug the ice machine before cleaning behind
the kickplate or making repairs.
• Setting power switch to OFF only removes power
from the refrigeration system, it does not remove
power from other circuits. To fully power-down the
machine it must be unplugged.
NOTE: WE STRONGLY RECOMMEND
THAT ANY SERVICING BE PERFORMED
BY A QUALIFIED INDIVIDUAL.
WARNING: PROPER INSTALLATION REQUIRES
CONNECTION TO THE WATER SUPPLY, A DRAIN
AND A DEDICATED ELECTRICAL CIRCUIT. THESE
CONNECTIONS ARE THE RESPONSIBILITIES OF
THE INSTALLER. IMPROPER CONNECTIONS CAN
RESULT IN PERSONAL INJURY, PROPERTY DAMAGE
AND IMPROPER OPERATION. THE ICE MACHINE
MUST BE INSTALLED ACCORDING TO ALL
APPLICABLE NATIONAL, STATE AND LOCAL
CODES AND REGULATIONS.

PROPER DISPOSAL OF
THE OLD ICE MACHINE
Child entrapment and suffocation are not problems
of the past. Junked or abandoned ice machines are
still dangerous, even if they will sit for “just a few
days.” If you are getting rid of your old ice machine,
please follow the instructions below to help prevent
accidents.
BEFORE YOU THROW AWAY YOUR OLD ICE MACHINE, TAKE
OFF THE DOORS.
CFC DISPOSAL
Your old ice machine may have a cooling system that
used CFCs (chlorofluorocarbons). CFCs are believed
to harm stratospheric ozone. If you are throwing away
your old ice machines, make sure the CFC refrigerant
is removed for proper disposal by a qualified service.
If you intentionally release this CFC refrigerant you
can be subject to fines and imprisonment under
provisions of the environment legislation.
WARNING & SAFETY LABELS
CAUTION:

ELECTRICAL SPECIFICATIONS
WARNING: THIS APPLIANCE MUST BE PROPERLY
GROUNDED. DO NOT, UNDER ANY CIRCUMSTANCES,
CUT OR REMOVE THE THIRD (GROUND) PRONG
FROM THE POWER CORD. FOR PERSONAL SAFETY,
THIS APPLIANCE MUST BE PROPERLY GROUNDED.
The electrical outlet must be within three feet of
the center of the back wall of the ice maker’s final
location. Outlet must be flush with wall and comply
with local electrical codes.
Before your new unit is connected to a power supply,
check the incoming voltage with a volt meter. If
anything less than 100% of the rated voltage for
operation is noted, correct immediately.
The power cord of this appliance is equipped with
a three-prong (grounding) plug which mates with
a standard three-prong (grounding) wall outlet to
minimize the possibility of electric shock hazard from
this appliance. A 115V AC, 60 Hz, 15 amp circuit
breaker and electrical supply are required.
Each unit requires a dedicated circuit. Have the wall
outlet and circuit checked by a qualified electrician to
make sure the outlet is properly grounded.
If the outlet is a standard
two-prong outlet, it is your personal
responsibility and obligation to have
it replaced with the properly
grounded three-prong wall outlet.
Do not use an extension cord or
two-prong adaptor. Electrical ground
is required on this appliance.
The unit should always be plugged into its own
individual electrical circuit which has a voltage rating
that matches the rating plate. This provides the best
performance and also prevents overloading house
wiring circuits which could cause a fire hazard from
overheated wires. Never unplug your ice machine by
pulling on the power cord. Always grip plug firmly and
pull straight out from the outlet.
Repair or replace immediately all power cords that
have become frayed or otherwise damaged. Do not
use a cord that shows cracks or abrasion damage
along its length or at either end. When moving the ice
machine away from the wall, be careful not to roll over
or damage the power cord.
The unit is approved by UL for outdoor installation.
OUTDOOR USE
All True undercounter ice machines are UL-rated for
outdoor use.
When installing outdoors, keep in mind that certain
regions may experience colder ambient temperatures
than others. When this decrease in temperature
occurs, the unit may stop producing ice before it is
full and begin showing FUL on the display. This is
caused because the internal thermostat has reached
the cut off temperature. Furthermore, these stainless
steel cabinets are very heavily insulated and will retain
the cold temperature for long periods of time.
The location of the unit will also play a factor in the
false full reading. If the unit is built into a kitchenette
area, within stone, brick, or wood etc., this will
further delay the reaction time. Basically, even if your
temperatures increase during the day, your cabinet
may be holding the colder temperature from the
evening before.
If your unit is showing a false full reading, rub your
hand on the inside ice level bar.
Once it senses the warm temperature it will start ice
production again. It is recommended during colder
periods to increase the ice level using the adjustment
screw. It is located behind the louver grill on the front
of the cabinet. The level can be increased by turning
the screw clockwise.
