Plumbing Connection Requirements
WARNING!
Only connect your ice machine to a potable water supply.
USER ACTION!
DO NOT connect the ice machine to a hot water supply.
Insulate the water line from sources of heat for greater operating efficiency.
Supply water temperatures higher than the recommended maximum will cause reduced capacities.
Inlet air gap included; no back-flow device required for the potable water inlet.
This UL listed model has greater than a 1" (25.4 mm) anti-back flow air gap between the water inlet tube end and the highest
possible sump water level.
For further information, please see ul.com/database.
Water filters recommended!
True recommends water filters for all ice machines. Water filters help remove particulate that reduces operating efficiency and
equipment life. Regularly changing water filters is essential for optimum-quality ice, reduced maintenance, and prolonged
equipment operation.
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. See "Removal From Service & Winterization" (pg. 58).
Fig. 1. Top plumbing connection example. Your application may differ.
Fig. 2. Bottom plumbing connection example. Your application may differ.
NOTICE!

To setup your water filter, see the following instructions.
1. In the upper right corner of the screen, press Menu .
2. In the Menu screen, press Water Filter.
3. In the Water Filter screen, select the appropriate water filter
for your application. True offers Standard and Platinum water
filtration systems. If using a non-TRUE water filter, enter the
water capacity under CUSTOM. See filter capacities in the
water filter capacities table.

Filter Type Capacity
Standard 14,000 gal (52,996 L)
Platinum 35,000 gal (132,490 L)
Custom (default) 10,000 gal (3,7854 L; adjustable)
Drain Requirements
• Run the ice machine drain line, dispenser unit/ice storage bin drain line, and water-cooled condenser drain line (if applicable)
separately.
• For optimum flow, drain lines must have 1/4" fall per 12" (20 mm fall per 1 m) of horizontal run.
• For correct drain flow, install a vented tee connection.
• Vent the sump drain. A vertical vent at the back of the drain, extended approximately 8-10" (203-254 mm) will allow the gravity drain
to empty and keep any surges during draining from discharging water out the vent.
• DO NOT directly pipe drain lines to the sewer system. Keep a vertical air gap [2" (50.8 mm) minimum] between the drain line ends
from the ice machine and condensation drain, dispenser unit/ice storage bin, and water-cooled condenser (if applicable) and the
floor drain.
• Insulate drain tubing in humid environments.

Fig. 1. FBD vs. EBD.
FULL BIN Control
The FULL BIN state is normally controlled by the harvest flap.
However, the ice level sensor can be used to control the FULL BIN
state of the machine by setting the value of TF1 equal to 1. This is
typically used when an ice machine is installed on a dispenser and
a lower ice level is required.
The machine will enter the FULL BIN state once the Value is greater
than the Full Bin Ice Threshold [PBD].
For instance, if PBD is set to 50, then the ice machine will enter the
FULL BIN state when the Value is greater than 50% (in other words,
when the ice storage unit is at least half full).
The machine will still enter the FULL BIN state if the damper is
held down.

Ice Machine Operation (cont.)
USER ACTION!
Before the ice machine will start MAKE ICE must be pressed and the ice damper must be in place.
Sequence of Operation
NOTICE!
Anytime the ice machine is in the OFF or FULL BIN state, the ice machine will drain water until the sump is empty.
Startup Cycle
The startup cycle consists of the self-diagnostic and refrigeration startup sequences.
Self-Diagnostics
Upon startup, the ice machine performs a series of self-diagnostic tests to ensure proper operation of critical components. During this brief
period the ice machine will fill and drain with water. This tests component operations as well as helps rid the ice machine of undesirable
sediment from the sump.
Refrigeration Startup
The ice machine will then energize the harvest valve and start the refrigeration system in the HARVEST cycle. This is to ensure no ice
remains on the evaporator before the ice machine enters the FREEZE cycle.
Freeze Cycle
The water pump energizes, and water is circulated over the evaporator that is being chilled by the refrigeration system. As more heat is
removed from the water, it begins to freeze and build ice on the evaporator. As the cycle continues the ice grows thicker and the water
level in the sump begins to drop. Once enough water is frozen to form a full sheet of ice the water level is low enough that the water level
sensor will initiate the HARVEST cycle. The water pump and fan motor(s) will de-energize.
Harvest Cycle
The harvest valve, drain valve and water inlet valve energize, which allows sediment to drain and starts to refill the sump water for the next
cycle. As hot refrigerant flows into the evaporator, it begins to warm the evaporator enough to release ice from the evaporator. The ice will
fall and contact the damper door at the bottom of the evaporator. The damper will pivot down to an open position and, if the ice storage
unit is not full, the damper will pivot back up to closed position. This signals the ice machine to start another FREEZE cycle. The ice machine
will continue to repeat the FREEZE and HARVEST cycles until the ice storage unit is full.
Full Bin
When the ice storage unit is full, the sheet of ice will prevent the damper door from pivoting back up to a closed position. After several
seconds of the damper remaining open, the ice machine will shut off and display FULL BIN. The drain valve will energize and drain the
remaining water from the sump to prevent sediment build-up. Once the ice melts or ice is removed from the ice storage unit, the damper
will pivot back to a closed position and the ice machine will restart in the STARTUP cycle.

These lamps contain a small amount of mercury sealed within the glass tubing. When a lamp breaks, some of this mercury is released as
mercury vapor. The broken lamp can continue to release mercury vapor until it is cleaned and removed from the area. These lamps fall
under the same category as compact fluorescent light (CFL). To minimize exposure to mercury vapor, the EPA recommends that residents
follow the cleanup and disposal steps described below.
This cleanup guidance represents the minimum actions recommended to clean up a broken CFL. For more detailed instructions and
information, please see U.S. Environmental Protection Agency (EPA) website at epa.gov.
The most important steps to reduce exposure to mercury vapor from a broken lamp include the following:
During Cleanup...
1. Thoroughly collect broken glass and visible powder.
WARNING!
Do not vacuum broken glass fragments!
Vacuuming is not recommended unless broken glass remains after all other cleanup steps have been taken.
Vacuuming could spread mercury-containing powder or mercury vapor.
2. Place cleanup materials in a sealed container.
WARNING!
The appliance owner is responsible for performing a Personal Protective Equipment (PPE) Hazard Assessment and ensuring
adequate protection during maintenance and cleaning procedures.
Use appropriate tools, safety equipment, and PPE during installation and servicing.
Before Cleanup...
1. Have people and pets leave the room
2. Air out the room 5-10 minutes by opening a window or door to the outdoor environment.
3. Shut off any central forced air heating/air-conditioning systems.

Exterior Cleaning
• Clean the area around the ice machine as needed to maintain cleanliness and efficient operation.
• Wipe surfaces with a damp cloth rinsed in water to remove dust and dirt from the ice machine's exterior.
Descaling and Sanitizing Procedures (bi-annually, minimum)
USER ACTION!
If a greasy residue remains on the surface, use a mild dish soap and water solution with a damp cloth. Wipe dry
with a clean, soft cloth.
NOTICE!
The exterior panels have a clear coating that is stain resistant and easy to clean.
Products containing abrasives will damage the coating and scratch the panels.
• Never use steel wool or abrasive pads.
• Never use chlorinated, citrus based or abrasive cleaners on exterior panels and plastic trim pieces.
DANGER!
HIGHLY CORROSIVE CLEANING CHEMICALS.
AVOID CONTACT WITH EYES AND SKIN.
WEAR EYE PROTECTION AND CHEMICAL-RESISTANT RUBBER GLOVES WHEN HANDLING.
WARNING!
Toxic material hazard!
DO NOT MIX DESCALER WITH SANITIZER. Harmful fumes may be generated.
Optical radiation hazard! UV light!
Invisible laser radiation. Do not look directly at light. Always disconnect power before servicing the lamp.
USER ACTION!
True recommends using True Ice Machine Descaler. To purchase, contact True Parts Department at 800-424-8783 or
PartsInquiries@TrueMFG.com.
If using a non-TRUE descaler (Nickel-safe) recommended dilution for soaking parts is 3 fl oz (88.7 mL) per 1 gal (3.78 L) and
recommended amount for evaporator cleaning is 6-8 fl oz (177.4-236.6 mL).

Descaling
1. Remove all ice from the bin (or dispenser if applicable).
2. Loosen the front panel screws and open the front panel.
3. In the home screen press CLEAN .
4. Press DESCALE.
5. Choose between the options.
PREVENTATIVE MAINT.: Shorter cycles; use between
bi-annual maintenance.
STANDARD: Normal cycle times; use when performing regular
bi-annual maintenance.
HEAVY: Longer cycle times; use when heavy scaling on parts
is obvious.
6. When "Would you like the unit to start making ice once
descaling and/or sanitizing is complete?" appears,
press NO.
7. Wait for the ice machine to run through the PRE-CLEANING
sequence (FILL, PUMP, DRAIN, and HARVEST). If there is enough
water in the sump at the start of CLEAN, it will go through
a DRAIN sequence before FILL. The compressor will start
during the HARVEST sequence to ensure there is no ice on
the evaporator and will shut off before the cleaning sequence
continues.
8. When ADD CLEANER appears, open the water curtain and
pour 10 oz (296 mL) of TRUE ice machine descaler between
the evaporator and the damper.
9. After adding descaler, press OK. The display will then show the
sequence status.

In cases where scale build up is particularly
heavy, substitute equal amounts ice machine descaler and
warm water.
12. Remove parts for cleaning. See below.
A. Water Curtain: Remove by placing one hand over the top
lip of the curtain and the other hand on the side of the curtain.
Gently flex the curtain on the side toward the center while
gently pulling the top outward.
B. Damper: Remove by pushing the damper down until
horizontal, pull forward gently until it stops and then push
down until it stops and pull forward.
C. Sump: Reach under the sump and pull off the drain hose.
Then place fingers between the left or right bulkhead wall and
the side of the sump. Place the other hand over the lip of the
sump. Push the sump with your fingers toward the opposite
bulkhead wall while pulling the sump in the same direction
with your hand until it comes out of the snap bracket. Repeat
the process on the other side and remove the sump.
D. Evaporator Area Cover: Remove by pushing up from the
inside of evaporator section.
E. Water Distributor: Remove by grabbing the two distributor
tabs and pull up slightly then forward.
13. With half of the solution, soak the parts for 5-10 minutes (if
heavily scaled, 15-20 minutes). Then with a soft nylon bristle
brush, cloth, or sponge, thoroughly clean the parts.
14. Thoroughly rinse the parts with clean water.
15. With the remaining solution and a soft nylon bristle brush, cloth,
or sponge, thoroughly clean all food zone areas (shaded
components) of the ice machine. These areas include the
following:
• Side walls
• Plastic evaporator top frame (where distributor is installed)
• Plastic evaporator sides and bottom
• Water pump base
• Water pump tubing
• Sump drain tubing
