STR•STA
•STG
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 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 building wiring circuits which could cause a
fire hazard from overheated wires. Never unplug your unit 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 unit away from the wall, be careful not to roll over or damage the power cord.
HOW TO CONNECT ELECTRICITY
Do not, under any circumstances, cut or remove the ground prong from the power cord. For personal safety, this
appliance must be properly grounded.
WARNING!
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.

REMOVAL FROM WOODEN SKID / INSTALLATION OF LEGS AND CASTORS
Important Safeguard for installation of leg/castor (Images below that demonstrate procedure)
Removal from wooden skid
1. Make sure unit is as close to the final location as possible.
2. Remove the shipping bolts located at the bottom of the wooden skid.
3. Carefully slide the unit off the wooden skid. Slide packing material
underneath the side of the unit hanging off the skid. Then install castors or
legs for that side of the unit. (See images below for install)
4. Then carefully slide the other side of the unit off one corner at a time while
installing castors or legs for each corner. Use packing material for under each corner of the unit before
installing a castor or leg.
Securing Castors and Legs
To obtain maximum strength and stability of the unit, it is important that you make sure each castor is secure. Legs
are hand-tightened securely against the base of the cabinet.
Unit Leveling
Shims have been provided for leveling castored units positioned on uneven floors. Shims must be positioned between the
bottom of the cabinet and the castor plate.
1. Level cabinet front to back and side to side (diagonally). Use the shims provided and slide them between the
cabinet bottom and the castor plate. Loosen anchor bolts to slide shims above castor plate.
2. Tighten and secure the castor by tightening the four anchoring bolts with a 3/4 inch open-end wrench,
socket.

A. Set unit in its final location. Be sure there is adequate ventilation in your room. Under extreme heat conditions,
(100°F+, 38°C+), you may want to install an exhaust fan.
WARNING
Warranty is void if ventilation is insufficient.
B. Proper leveling of your TRUE unit is critical to operating success (for non-mobile models). Effective condensate removal
and door operation will be effected by leveling.
C. The unit should be leveled front to back and side to side with a level.
D. Ensure that the drain hose or hoses are positioned in the pan.
E. Free plug and cord from the top of the unit (do not plug in).
F. The unit should be placed close enough to the electrical supply so that extension cords are never used.
WARNING
Compressor warranties are void if the unit is more than 7 ft. (2.1m) from plug-in connection.
LEVELING
Optional
A. It may be necessary to seal the cabinet to the floor for local sanitary codes or if the customer so desires. TRUE recom-
mends either of the following methods:
B. Using a vinyl cove base trim as produced by Armstrong, Johnson, or Kentile (available at floor covering suppli-
ers) or using mastics available at hardware stores.
C. When applying the cove base trim, thoroughly clean both the cabinet and floor of dirt and grease. Apply a rec-
ommended contact cement to the cove base trim. After cove base trim has dried, fill in cracks and joints with a
caulking material.
D. When applying a mastic, draw an outline of the cabinet on the floor. Raise and block the front side of the cabi-
net. Apply a bead of mastic to the floor 1/2” inside the outline drawn. Lower the cabinet. Raise and block the rear
side of the cabinet. Apply the bead of mastic, lower the cabinet.
SEALING CABINET TO FLOOR

A. Before your new unit is connected to a power supply, check the incoming voltage with a voltmeter. If anything
less than 100% of the rated voltage for operation is noted, correct immediately.
B. All units are equipped with a power cord, and must be powered at proper operating voltage at all times. Refer to
cabinet data plate for this voltage.
TRUE requires that a sole use circuit be dedicated for the unit. Failure to do so voids warranty.
WARNING
Compressor warranties are void if compressor burns out due to low voltage.
WARNING
Power supply cord ground should not be removed!
NOTE
To reference wiring diagram - locate the diagram on the junction box cover.

LAE Control Sequence of Operation
1. Cabinet is plugged in.
a. Display will illuminate.
b. Interior lights will illuminate on Glass Door models only. (If lights do not come on please see
instructions on following pages(s).) Solid Door cabinet lights are controlled by door switch.
2. After the LAE control preprogrammed time delay of 3 minutes (freezers only), the compressor and evaporator
fan(s) will start if the control is calling for cooling.
a. Control may be already preprogrammed 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 together
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 pages(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 specifi c times of day. (If additional
Defrost Intervals / Cycles are needed or a manual defrost is required due to conditions please see instructions
on next 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 / Cycles may be adjusted due to certain conditions.
This sequence is NOT model specifi c.

MAINTENANCE, CARE & CLEANING
CLEANING THE CONDENSER COIL
When using electrical appliances, basic safety precautions should be followed, including the following:
Condenser Cleaning
Thumbscrew Location
Louver grill in upright position
Thumbscrews located
on cabinet ends

STR•STA
•STG
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 the Spec Series units the condenser is accessible on the top of the unit. You must lift open the cabinet rainshield to
expose the Condenser. (Spec Series models)
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. Open the rainshield.
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 close the rainshield.
6. Reconnect the electrical power to the unit.

IMPORTANT WARRANTY INFORMATION
22
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
STAINLESS STEEL EQUIPMENT CARE AND CLEANING

STR•STA
•STG
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.
