SAFETY INFORMATION
PROPER DISPOSAL OF THE FREEZER /
REFRIGERATOR
DANGER!
RISK OF CHILD ENTRAPMENT
USE OF EXTENSION CORDS
NEVER USE AN EXTENSION CORD! TRUE will not warranty any refrigerator that has been connected to an extension cord.
Child entrapment and suffocation are not problems
of the past. Junked or abandoned refrigerators are still
dangerous… even if they will sit for “just a few days.” If
you are getting rid of your old refrigerator, please follow
the instructions below to help prevent accidents.
Before You Throw Away Your Old Refrigerator or
Freezer:
• Take off the doors.
• Leave the shelves in place so that children may not
easily climb inside.
Refrigerant Disposal
Your old refrigerator may have a cooling system
that uses “Ozone Depleting ” chemicals. If you are
throwing away your old refrigerator, make sure the
refrigerant is removed for proper disposal by a
qualified service technician. If you intentionally
release any refrigerants you can be subject to
fines and imprisonment under provisions of the
environmental regulations.

WARNING!
SAFETY INFORMATION
The power cord of this appliance is equipped with a
grounding plug which mates with a standard grounding wall
outlet to minimize the possibility of electric shock hazard from
this appliance.
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 2-prong outlet, it is your personal
responsibility and obligation to have it replaced with the
properly grounded wall outlet.
The refrigerator should always be plugged into it’s own
individual electrical circuit, which has a voltage rating that
matches the rating plate.
This provides the best performance and also prevents
overloading building wiring circuits which could cause a fire
hazard from overheated wires.
Never unplug your refrigerator 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 removing the refrigerator away from the wall, be
careful not to roll over or damage the power cord.

REQUIRED TOOLS
NOTE
Units with a solar thermometer will experience a 15 second delay
after exposed to light before it reads the proper temperature.
The following procedure is recommended for uncrating the
unit:
A. Remove the outer packaging, (cardboard and bubbles or
styrofoam corners and clear plastic). Inspect for concealed
damage. Again, immediately file a claim with the freight
carrier if there is damage.
B. Move your unit as close to the final location as possible
before removing the wooden skid.
C. Remove door bracket on swinging glass door models (see
image 1-2). Sliding glass door models contain shipping
blocks (three for each door). Remove the two styrofoam
blocks taped to the top of the door tracks (see image 3).
The shipping blocks are orange in color and by opening
the door a little the blocks can be removed (see images
4-6). Do not throw the bracket or blocks away. For future
cabinet movement the bracket and blocks will need to be
installed so the glass door does not receive any damage.

2. After the LAE control preprogrammed time delay of 3 minutes, the compressor and evaporator fan(s) will start if
the control is calling for cooling.
a. Control may be already pre-programmed from the factory so at the start of every compressor cycle or
during a defrost cycle, the condenser fan(s) will reverse for 30 seconds to blow dirt off the condensing
coil.
3. The LAE control will cycle the compressor but may also cycle evaporator fan(s) on and off determined by the
Set-Point and Differential temperatures. (If the Set-Point needs to be changed due to conditions please see
instructions on the following page(s).)
a. The Set-Point is the preprogrammed temperature which shuts off the compressor.
b. The Differential is the preprogrammed temperature that is added to the Set-Point temperature that will
start the compressor.
Example: If the Set-Point is -9°F/-23°C and the Differential is 10°F/5°C
(Set-Point) -9°F + 10 (Differential) = 1°F
Or
(Set-Point) -23°C + 5 (Differential) = -18°C
The compressor and evaporator fan(s) will cycle off -9°F/-23°C
and back on at 1°F/-18°C
4. The LAE control may be preprogrammed to initiate defrost by interval or at specic times of day. (If additional
Defrost Intervals or Cycles are needed or a Manual Defrost is required due to conditions please see instruc-
tions on the following page(s).)
a. At this time the “dEF” will appear on the display and compressor will turn off until a preprogrammed
temperature or duration is reached. During this time for freezers only, evaporator fan(s) will also
turn off and the coil heater and drain tube heaters will also be energized.
b. After the preprogrammed temperature or duration for defrost has been reached there may be a short
delay for both the compressor and evaporator fans to restart. At this time “dEF” may still appear
on the display for a short time.
True Manufacturing recommends that ONLY the Set-Point and/or
Defrost Interval may be adjusted due to certain conditions.
This sequence is NOT model specific.

INSTALLATION / OPERATION INSTRUCTIONS
IF THE COMPRESSOR WILL NOT RUN
1. If there is no voltage at the compressor
terminals, follow the wiring diagram
and check back from compressor to the
power supply to find where the circuit is
interrupted.
2. If power is available at the compressor
terminals, and the compressor does not
run, check the voltage at the compressor
terminals while attempting to start the
compressor.
If voltage at the compressor terminals is
below 90% of the nameplate voltage, it
is possible the motor may not develop
sufficient torque to start. Check to
determine if wire sizes are adequate,
electrical connections are loose, the
circuit is overloaded, or if the power
supply is inadequate.
3. On single phase compressors,
a defective capacitor or relay may
prevent the compressor starting. If the
compressor attempts to start but is
unable to do so, or if there is a humming
sound, check the relay to see if the relay
contacts are damaged or fused. The relay
points should be closed during the initial
starting cycle, but should open as the
compressor comes up to speed.
Remove the wires from the starting
relay and capacitors. Use a high voltage
ohmmeter to check for continuity
throughout the relay coil. Replace
the relay if there is not continuity.
Use an ohmmeter to check across the
relay contacts. Potential relay contacts
are normally closed when the relay is
not energized, current relay contacts
are normally open. If either gives an
incorrect reading, replace the relay.
Any capacitor found to be bulging,
leaking, or damaged should be replaced.
Make sure capacitors are discharged
before checking. Check for continuity
between each capacitor terminal and the
case. Continuity indicates a short, and
the capacitor should be replaced.
Substitute a “known to be good” start
capacitor if available. If compressor then
starts and runs properly, replace the
original start capacitor.
If a capacitor tester is not available, an
ohmmeter may be used to check run
and start capacitors for shorts or open
circuits. Use an ohmmeter set to its
highest resistance scale, and connect
prods to capacitor terminals.
a) With a good capacitor, the
indicator should first move zero, and
then gradually increase to infinity.
b) If there is no movement of the
ohmmeter indicator, an open circuit is
indicated.
c) If the ohmmeter indicator moves
to zero, and remains there or on a low
resistance reading, a short circuit is
indicated. Defective capacitors should be
replaced.
4. If the correct voltage is available
at the compressor terminals, and no
current is drawn, remove all wires from
the terminals and check for continuity
through the motor windings. On single
phase motor compressors, check for
continuity from terminals C to R, and
C to S. On compressors with line break
inherent protectors, an open overload
protector can cause a lack of continuity.
If the compressor is warm, wait one hour
for the compressor to cool and recheck.
If continuity cannot be established
through all motor windings, the
compressor should be replaced.
Check the motor for ground by means of
a continuity check between the common
terminal and the compressor shell. If
there is a ground, replace the compressor.
5. If the compressor has an external
protector, check for continuity through
the protector or protectors. All external
inherent protectors on compressors can
be replaced in the field.
IF THE MOTOR COMPRESSOR STARTS
BUT TRIPS REPEATEDLY ON THE
OVERLOAD PROTECTOR
1. Check the compressor suction and
discharge pressures while the compressor
is operating. Be sure the pressures are
within the limitations of the compressor.
If pressures are excessive it may be
necessary to clean the condenser, purge
air from the system, replace crankcase
pressure regulating valve.
An excessively low suction pressure may
indicate a loss of charge.
On units with no service gauge parts
where pressures can be checked, check
condenser to be sure it is clean and fan
is running. Excessive temperatures on
suction and discharge line may also
indicate abnormal operating conditions.
2. Check the line voltage at the motor
terminals while the compressor is
operating. The voltage should be within
10% of the nameplate voltage rating. If
outside those limits, the voltage supply
must be brought within the proper
range, or a motor compressor with
different electrical characteristics must be
used.
3. Check the amperage drawn while the
compressor is operating. Under normal
operating conditions, the amperage
drawn will seldom exceed 110% of the
nameplate amperage. High amperage
can be caused by low voltage, defective
running capacitors, or a defective starting
relay.
Continued on next page
............ www.truemfg.com ............
True Food Service Equipment, Inc.
26 26
INSTALLATION / OPERATION INSTRUCTIONS
4. If all operating conditions are
normal, the voltage supply at the
compressor terminals balanced and
within limits, the compressor crankcase
temperature within normal limits, and
the amperage drawn within the specified
range, the motor protector may be
defective, and should be replaced.
If the operating conditions are normal
and the compressor is running excessively
hot for no observable reason, or if the
amperage drawn is above the normal
range and sufficient to repeatedly trip the
protector, the compressor has internal
damage and should be replaced.
IF THE COMPRESSOR RUNS BUT WILL
NOT REFRIGERATE
1. Check the refrigerant charge. Check
the evaporator surface to determine
if it is evenly cold throughout, or if
partially starved. A lack of charge may
be indicated by light, fluffy frost at
the evaporator inlet. Add refrigerant if
necessary.
2. Check the compressor suction
pressure. An abnormally low pressure
may indicate a loss of refrigerant charge,
a malfunctioning capillary tube, a lack of
evaporator capacity possibly due to icing
or low air flow, or a restriction in the
system.
Often a restriction in a drier or strainer
can be identified by frost or a decrease
in temperature across the restriction due
to the pressure drop in the line. This
will be true only if liquid refrigerant is in
the line at the restricted point, since any
temperature change due to restriction
would be caused by the flashing of liquid
into vapor as the pressure changes.
Any abnormal restriction in the system
must be corrected.
3. Check the compressor discharge
pressure. An abnormally high discharge
pressure can cause a loss of capacity, and
can be caused by a dirty condenser, a
malfunctioning condenser fan, or air in
the system.
4. If the suction pressure is high,
and the evaporator and condenser
are functioning normally, check the
compressor amperage draw. An amperage
draw near or above the nameplate rating
indicates normal compressor or unit may
have damaged valves.
An amperage draw considerably below
the nameplate rating may indicate a
broken suction reed or broken
connecting rod in the compressor.
DIAGNOSIS AND REPLACEMENT OF
FREEZER CABINET COMPONENTS
1. Defrost Time Clock
A. Check timer motor to be sure
it runs.
B. Check contacts on the defrost
timer.
C. Check solenoid windings for
continuity to ensure contact
switching.
D. Check to be sure defrost
actuator pins are in proper
position.
E. Check all wires in the timer for
tightness to terminals and
broken wires.
2. Defrost Control On The
Evaporator Drain Pan
A. If the defrost time is always
35 minutes (or whatever duration the
elapsed time adjustment is set at) and
the fan motors do not delay after a
defrost cycle and it has been determined
that the solenoid in the defrost clock is
functioning, change the defrost control
in the evaporator compartment in
the top of the freezer. This control is
attached to the evaporator drain pan.
3. Coil Defrost Heater
A. Lower the evaporator cover.
Disconnect the coil heater by removing
the wire nuts at the point where the
heater joins the electrical circuit of the
freezer in the evaporator compartment.
Check heater for continuity with an
ohmmeter. If the heater is defective, cut
the bale wires holding the heater to the
coil and remove the heater. Replace with
a new heater using bale wires provided.
4. Drain Tube Heater
A. Lower the evaporator cover.
Disconnect the drain tube heater by
removing the wire nuts at the point
where the heater joins the electrical
circuit of the freezer in the evaporator
compartment. Check the drain tube
heater with an ohmmeter.
B. If the drain tube heater is
defective, disconnect the drain tube from
the rigid plastic drain, bend the tabs that
hold the evaporator drain pan to the
evaporator cover and raise the drain pan
so that the flexible heater is visible, pull
heater out of the plastic drain tube and
replace. Connect heater to the electrical
circuit in the evaporator compartment.
5. Cabinet Temperature
Control
A. Remove the two screws on the
right side of the evaporator housing that
holds the control mounting plate. Reach
behind the evaporator housing on the
control side of the cabinet and pull the
control bulb out of the receptacle in
the roof of the cabinet. Disconnect the
wires from the control. Check control for
continuity, replace if defective.

Condensers accumulate dirt and require cleaning every 30 days. Dirty condensers result in compressor failure, product loss,
and lost sales... which are not covered by warranty.
If you keep the Condenser clean you will minimize your service expense and lower your electrical costs. The Condenser
requires scheduled cleaning every thirty days or as needed.
Air is pulled through the Condenser continuously, along with dust, lint, grease, etc.
A dirty Condenser can result in NON-WARRANTEED part & Compressor Failures, Product Loss, and Lost Sales.
Proper cleaning involves removing dust from the Condenser. By using a soft brush, or vacuuming the Condenser with a shop
vac, or using CO2, nitrogen, or pressurized air.
If you cannot remove the dirt adequately, please call your refrigeration service company.
On most of the units the condenser is accessible in the rear of the unit. You must remove the cabinet grill to expose the
Condenser.
The Condenser looks like a group of vertical fins. You need to be able to see through the condenser for the unit to function at
maximum capacity. Do not place filter material in front of condensing coil. This material blocks air-flow to the coil similar to
having a dirty coil.
THE CLEANING OF THE CONDENSER IS NOT
COVERED BY THE WARRANTY!
HOW TO CLEAN THE CONDENSER:
1. Disconnect the electrical power to the unit.
2. Remove the louvered grill.
3. Vacuum or brush the dirt, lint, or debris from the finned condenser coil.
4. If you have a significant dirt build up you can blow out the condenser with compressed air.
(CAUTION MUST BE USED to avoid eye injury. Eye protection is recommended.)
5. When finished be sure to replace the louvered grill. The grill protects the condenser.
6. Reconnect the electrical power to the unit.
If you have any questions, please call TRUE Manufacturing at 636-240-2400 or 800-325-6152 and ask for the Service
Department. Service Department Availability Monday-Friday 7:30 a.m. to 6:00 p.m. and Saturday 8:00 a.m. to 12:00 p.m. CST.

MAINTENANCE, CARE & CLEANING
CAUTION: Do not use any steel wool, abrasive or chlorine based products to clean stainless steel surfaces.
• Stainless Steel Opponents
There are three basic things which can break down your stainless steel’s passivity layer and allow corrosion to rear
its ugly head.
1) Scratches from wire brushes, scrapers, and steel pads are just a few examples of items that can be abrasive to
stainless steel’s surface.
2) Deposits left on your stainless steel can leave spots. You may have hard or soft water depending on what part of
the country you live in. Hard water can leave spots. Hard water that is heated can leave deposits if left to sit too
long. These deposits can cause the passive layer to break down and rust your stainless steel. All deposits left from
food prep or service should be removed as soon as possible.
3) Chlorides are present in table salt, food, and water. Household and industrial cleaners are the worst type of
chlorides to use.
• 8 steps that can help prevent rust on stainless steel:
1. Using the correct cleaning tools
Use non-abrasive tools when cleaning your stainless steel products. The stainless steel’s passive layer will not be
harmed by soft cloths and plastic scouring pads. Step 2 tells you how to find the polishing marks.
2. Cleaning along the polish lines
Polishing lines or “grain” are visible on some stainless steels. Always scrub parallel to visible lines on some stainless
steels. Use a plastic scouring pad or soft cloth when you cannot see the grain.
3. Use alkaline, alkaline chlorinated or non-chloride containing cleaners
While many traditional cleaners are loaded with chlorides, the industry is providing an ever increasing choice of
non-chloride cleaners. If you are not sure of your cleaner’s chloride content contact your cleaner supplier. If they
tell you that your present cleaner contains chlorides, ask if they have an alternative. Avoid cleaners containing
quaternary salts as they can attack stainless steel, causing pitting and rusting.
4. Water Treatment
To reduce deposits, soften the hard water when possible. Installation of certain filters can remove corrosive and
distasteful elements. Salts in a properly maintained water softener can be to your advantage. Contact a treatment
specialist if you are not sure of the proper water treatment.
5. Maintaining the cleanliness of your food equipment
Use cleaners at recommended strength (alkaline, alkaline chlorinated or non-chloride). Avoid build-up of hard
stains by cleaning frequently. When boiling water with your stainless steel equipment, the single most likely cause
of damage is chlorides in the water. Heating any cleaners containing chlorides will have the same damaging effects.
6. Rinse
When using chlorinated cleaners you must rinse and wipe dry immediately. It is better to wipe standing cleaning
agents and water as soon as possible. Allow the stainless steel equipment to air dry. Oxygen helps maintain the
passivity film on stainless steel.
7. Hydrochloric acid (muriatic acid) should never be used on stainless steel
8. Regularly restore/passivate stainless steel

Recommended cleaners for certain situations / environments of stainless steel
A) Soap, ammonia and detergent medallion applied with a cloth or sponge can be used for routine
cleaning.
B) Arcal 20, Lac-O-Nu Ecoshine applied provides barrier film for fingerprints and smears.
C) Cameo, Talc, Zud First Impression is applied by rubbing in the direction of the polished lines for
stubborn stains and discoloring.
D) Easy-off and De-Grease It oven aid are excellent for removals on all finishes for grease-fatty acids,
blood and burnt-on foods.
E) Any good commercial detergent can be applied with a sponge or cloth to remove grease and oil.
F) Benefit, Super Sheen, Sheila Shine are good for restoration / passivation.
NOTE
The use of stainless steel cleaners or other such solvents is not
recommended on plastic parts. Warm soap and water will suffice.

TRUE warrants to the original purchaser of every new TRUE refrigerated unit, the cabinet and all parts thereof, to be free from defects in
material or workmanship, under normal and proper use and maintenance service as specified by TRUE and upon proper installation and start-up in
accordance with the instruction packet supplied with each TRUE unit. TRUE’s obligation under this warranty is limited to a period of three (3) years
from the date of original installation or 39 months after shipment date from TRUE, whichever occurs first.
Any part covered under this warranty that are determined by TRUE to have been defective within three (3) years of original installation or
thirty-nine (39) months after shipment date from manufacturer, whichever occurs first, is limited to the repair or replacement, including labor charges,
of defective parts or assemblies. The labor warranty shall include standard straight time labor charges only and reasonable travel time, as determined
by TRUE.
Warranty does not cover standard wear parts which include door gaskets, incandescent bulbs or fluorescent bulbs. Warranty also does
not cover issues caused by improper installation or lack of basic preventative maintenance which includes regular cleaning of condenser coils.
In addition to the Three (3) year warranty stated above, TRUE warrants its hermetically and semi-hermetically sealed compressor to be free
from defects in both material and workmanship under normal and proper use and maintenance service for a period of two (2) additional years from the
date of original installation but not to exceed five (5) years and three (3) months after shipment from the manufacturer.
Compressors determined by TRUE to have been defective within this extended time period will, at TRUE’s option, be either repaired or
replaced with a compressor or compressor parts of similar design and capacity.
The two (2) year extended compressor warranty applies only to hermetically and semi-hermetically sealed parts of the compressor and
does not apply to any other parts or components, including, but not limited to: cabinet, paint finish, temperature control, refrigerant, metering device,
