SAFETY INFORMATION
DANGER!
RISK OF CHILD ENTRAPMENT
HOW TO SAFELY DISPOSE OF USED
REFRIGERATION EQUIPMENT
Child entrapment and suffocation are not problems
of the past. Junked or abandoned display cases are
still dangerous… even if they will sit for “just a few
days.”
It is much safer if doors and lids are removed so
children cannot get trapped inside, leaving the
shelves in place will also deter children from trying to
climb inside.
If you are getting rid of your old display case, please
follow the instructions below to help prevent
accidents. Depending on the country where the
unit is located there will be officially approved ways
of disposing of your used equipment.
It is important that care is taken in disposing of used
refrigerators or freezers. 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
Depending on the country where the unit is located
there will be Officially approved way of disposing
of your used equipment. 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.

INSTALLATION OF LEGS AND CASTORS
Step 3
Securing Castors:
To obtain maximum strength and stability of the
unit, it is important that you make sure each castor
is secure. The bearing race on the castor of the top
edge of the leg must make firm contact with the
rail.
Unit Leveling:
Four leveling shims have been provided for leveling
castored units positioned on uneven floors. Shims
must be positioned between rail end and bearing race.
True recommends a four shim limit to any single castor.
A. Turn the bearing race counter-clockwise until
the cabinet is level. Level front to back and side to
side. (diagonally)
B. Install the desired number of shims, making sure
the slot of the shim is in contact with the threaded
stem of the castor.
C. If more than one shim is used, turn the slot at a
90° angle so they are not in line.
D. Turn the bearing race clockwise to tighten and
secure the castor by tightening the anchoring bolt
with a 3/4 inch open-end wrench, socket, or the
tool provided.
CAUTION
To avoid damage to lower rail assembly, slowly raise
unit to upright position after installing castors.

MAINTENANCE, CARE & CLEANING
STAINLESS STEEL EQUIPMENT CARE AND CLEANING
CAUTION: Do not use any steel wool, abrasive or chlorine based products to clean stainless steel surfaces. Please
ensure that you use appropriate products when cleaning and polishing your True unit. Cleaners containing chlorine
must not be used as these will attack the stainless steel causing damage and in some cases corrosion. Your supplier of
cleaning products should be able to advise you of the products suitable to keep your True unit looking like new.
• 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
