for imperfection?
(Cosmetic defects are covered by a limited 30-day warranty)
☐Have all packaging materials been removed?
☐Is the unit properly leveled with all leveling legs contacting the floor?
☐Has the water filter been installed? Has the water supply been turned on?
☐Have the water supply and drain connections been made?
☐Is the water supply temperature always between 40-100˚F (4.4-7.8˚C)?
☐Has the ice machine drain line been routed into an open drain with no more than 84"
(2,133.6 mm) vertical rise for 3/8" O.D. tubing and no more than 100’ (30.48 m) run?
☐Has the water supply been turned on?
☐Is the power cord plugged into a properly grounded three-prong outlet in accordance with all
applicable electrical codes?
☐Have all connections been checked for water leaks? If not, pour water directly into the ice
storage bin to ensure drain pump operation and inspect for leaks.
☐Were the ice machine and storage bin disinfected prior to use? If not, see “Sanitize" (pg. 54).
☐Has the ice machine been turned on? During the initial fill, can you hear the water valve turn on
and see water filling the reservoir tank?
☐After the first ice cycle, did all 24 ice cubes fall into the bin during harvest?
☐Has the ice produced in the first hour of operation been discarded?
☐Has the customer reviewed the unit’s operation in this manual?
☐Has the customer reviewed the schedule of maintenance of the machine?

SAFETY INFORMATION & OWNERSHIP
OWNERSHIP
To ensure that your unit works properly from the
first day, it must be installed properly. We highly
recommend a trained refrigeration mechanic and
electrician install your True equipment. The cost of a
professional installation is money well spent.
Before you start to install your TRUE unit, carefully
inspect it for freight damage. If damage is discovered,
DO NOT INSTALL THE UNIT or put it in service. Notify
True customer service, and immediately file a claim
with the delivery freight carrier.
TRUE is not responsible for damage incurred during

For any questions about installation, please contact
your True dealer or True Residential Technical Service
at 844-746-9423 or TrueResidentialService@TrueMfg.
com. Please have your model and serial number
available.
NOTICE: PROPER INSTALLATION
REQUIRES A 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

manufacturer.
NOTE: ALL SERVICING MUST BE
PERFORMED BY A QUALIFIED TECHNICIAN.
PROPER DISPOSAL OF THE
APPLIANCE
DANGER! RISK OF CHILD
ENTRAPMENT
Child entrapment and suffocation are not problems
of the past. Junked or abandoned appliances are still
dangerous, even if they will sit for "just a few days." If
you are getting rid of your old appliance, please follow
the instructions below to help prevent accidents.
Before throwing away your old ice machine:
Take off the door.
DANGER! Risk of fire or explosion.
Flammable insulation and/or refrigerant
used. Dispose of all in accordance with
local and federal regulations. Follow all
safety precautions.
BASIC SAFETY & WARNING
PRECAUTIONS
• Take care during operation, maintenance or repairs
to avoid cuts or pinching from any part/component
of the appliance.
• Units may pose a tipping hazard while uncrating,
during installation, or when moving the unit.
• Ensure the unit is properly installed and located in
accordance with the Installation Instructions before
use.
• This appliance is not to be used, cleaned or
maintained by persons (including children) with
reduced physical, sensory or mental capabilities or
lack of experience and knowledge, unless they have
been given supervision or instruction.
• DO NOT allow children to play with the appliance
or climb, stand, or hang on the unit’s shelves to
prevent damage to the refrigerator and personal
injury.
• DO NOT touch the cold surfaces in the freezer
compartment when hands are damp or wet. Skin
may stick to these extremely cold surfaces.
• Unplug the ice machine before cleaning and making
repairs.
• Powering off the ice machine will not remove power
from all components (e.g., light circuit and drain
pump).
• DO NOT store or use gasoline, or other flammable
vapors and liquids, in the vicinity of this or any
other appliance.
