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,
immediately file a claim with the delivery freight carrier.
TRUE is not responsible for damage incurred during
shipment.
For any questions about installation, please contact
your True dealer or True Residential Technical Service
at 844-746-9423 or [e-mail].
Please have your model and serial number available.
WARNING – 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
PERSONAL INJURY, PROPERTY DAMAGE AND
IMPROPER OPERATION. THE ICE MACHINE
MUST BE INSTALLED ACCORDING TO ALL
APPLICABLE NATIONAL, STATE AND LOCAL
CODES AND REGULATIONS.
REFRIGERANT SAFETY & WARNING
INFORMATION
This unit contains hydrocarbon refrigerant (R-290).
Please carefully and completely read all safety labels
and the warnings below:
DANGER – Risk of fire or explosion.
Flammable refrigerant used. DO NOT use
mechanical devices to defrost refrigerator.
DO NOT puncture refrigerant tubing; follow
handling instructions carefully. To be
repaired only by trained service personnel.
DANGER – Risk of fire or explosion
(flammable refrigerant used), consult
repair manual/owner’s guide before
attempting to service this product. All
safety precautions must be followed.
Dispose of properly in accordance with
local and federal regulations. Follow all
safety precautions.
CAUTION – Keep all ventilation openings
clear of obstruction in the appliance
enclosure or in the structure housing the
appliance.
SAFETY LABELS & WARNING
Your new ice maker has labels placed in specific
locations throughout the cabinet which identify
important safety information. Please take a moment
to familiarize yourself with the content and label
locations.

BASIC SAFETY & WARNING
PRECAUTIONS
• Take care during operation, maintenance or repairs
to avoid cuts or pinching from any part/component
of the cabinet.
• 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 maker before cleaning and making
repairs.
• Powering off the ice maker 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.
• DO NOT store explosive substances such as aerosol
cans with a flammable propellant in this appliance.
• Keep fingers out of the "pinch point" areas;
clearances between the doors and cabinet are
necessarily small; be careful closing doors when
children are in the area.
• DO NOT use electrical appliances inside the food
storage compartments of the units unless the
appliances are of the type recommended by the
manufacturer.
NOTE: ALL SERVICING MUST BE
PERFORMED BY A QUALIFIED TECHNICIAN.
PROPER DISPOSAL OF THE CABINET
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.

SERIAL LABEL LOCATION
Your serial label contains important information such
as your model and serial number. The label is located
on the upper left interior wall.
OUTDOOR USE
All True undercounter ice machines are rated for
outdoor use.
• The unit must be covered or otherwise protected
from direct exposure to rain.

• If the unit is expected to be exposed to low air
temperatures for a prolonged period of time,
please turn the unit off and winterize the unit. See
“Winterizing” (page 54).
CAUTION: DO NOT ALLOW THE ICE MACHINE
TO BE EXPOSED TO TEMPERATURES BELOW
32˚F (0˚C) WITHOUT WINTERIZING THE UNIT
AS THIS WILL CAUSE ANY WATER IN THE
MACHINE TO FREEZE. FAILURES CAUSED BY
EXPOSURE TO FREEZING TEMPERATURES ARE
NOT COVERED BY THE WARRANTY.

When installing two or more True units side-by-side,
be sure to leave at least a 5/8” (15.88 mm) gap
between the cabinets, or install foam pads between
the cabinets and on any side with 0” clearance, to
prevent moisture from developing on applications.
If installing anti-sweat foam end panels, True

units being joined together. To order foam pads,
contact our parts department at 844-849-6226 or

PRIOR TO INSTALLATION
CUSTOM PANEL INSTALLATION
Your new ice machine comes with articulating, or soft-
closing, hinges. The hinges can be installed on either
the left of right to change the direction the door opens.
Before installing panels, be sure the door assembly is
oriented as desired. See “Reversing Door” (page 56).
Please closely read all instructions before installing
your panels.
REQUIRED TOOLS
Required tools include (but may not be limited to) the
following.
• Surface protection*
• 2+ Clamps ≥ 2” (51 mm)
• 1/8” Hex Head Allen Wrench
• Phillips Screwdriver or Bit Driver
• 1/8” Drill Bit
• (Qty 6) #6 x 1/2” Screws**
• Drill
*Cardboard, moving blanket, foam padding, etc.
**Screw type varies by panel material.
INSTALLATION
1. Carefully lay the door overlay panel face down on a
protected surface.
2. With a 1/8” hex head Allen wrench, loosen the
cabinet hinge bolts. Then, remove the door.
See fig.1.
NOTE: DO NOT REMOVE THE HINGE FROM THE
DOOR ASSEMBLY.
3. If NSF Cover is present, carefully pry screw caps
from the cover to access the door bracket screws.
See fig. 2.
NOTE: THE CAPS ARE INSTALLED WITH A
TACKY GLUE THAT CAN BE EASILY REMOVED
AND REINSTALLED.
4. Place the door front face down on the overlay
panel. Then, align the bottom door bracket’s
bottom edge with the overlay panel’s bottom edge.
See figs. 3 and 4.
5. Clamp the door assembly panel.
NOTE: IF THE CLAMP JAWS ARE NOT PADDED,
INSERT PADDING BETWEEN THE CLAMP AND
THE OVERLAY TO PROTECT THE PANEL’S
FINISH.
6. If desired, install a handle before proceeding to the
next step. For best installation, fasten the handle
with recessed screws.
7. With a 1/8” drill bit, carefully drill pilot holes into
the door front. See fig. 5.
NOTE: TAKE CARE TO NOT DRILL THROUGH THE
FRONT OF THE PANEL.
8. With the appropriate hardware, fasten the overlay
panel to the door front. Then, remove the clamps.
9. Install the door assembly. Be sure to fully tighten
the hinge screws.
10. Verify the door closes correctly and seals without
gaps. Adjust the door as needed; see “Door
Adjustment” (page 59).
