Installation summary for Precedent S-600 and S-700 Systems
The Precedent installs the same as the current SB with the following
exceptions:
1. Evaporator opening and mounting bolt locations on front wall of trailer did
not change. However, depending on your particular installation, two of the
mounting bolts lengths may need to be trimmed to 57.20 mm (2.25 in.)
long or they may interfere with the back of the control box and engine.See
“Mounting Hardware Requirements” on page 12.
2. The Precedent unit is approximately 6.00 inches wider than a SB which
may interfere with trailer mounted fresh air exchange doors.Thermo King
fresh air exchange option 070026 is also available. See “Evaporator
Opening Requirements” on page 10.
3. A new two point lifting bar is required to safely lift the unit during
installation. See “Lifting Bar Dimensions” on page 20.
4. A new fuel pump and bracket (TK supplied) will need to be installed onto
the trailer cross member directly above the fuel tank. All fuel line fittings
(TK supplied) are now nickel plated brass for S-600 and S-700 units. Any
additional fittings required for these units must also be nickel plated brass
or stainless steel. See “Installing the Fuel Pump and Harness” on
page 40.
5. Fuel supply and fuel return lines will need to be routed to the bottom of the
unit and fed up inside through the provided chase. The lines will need to
be cut to length and connected to the fuel filter or optional fuel heater with
the (TK supplied) nickel plated brass fittings for S-600 and S-700 units.
DO NOT use Teflon tape on fuel fittings. See “Installing the Fuel Lines”
on page 42.
6. It is recommended the installer provide a separate conduit or chase under
the trailer with a minimum inside diameter of 25.4 mm (1.00 in.) to
accommodate both the standard fuel pump harness and the ultrasonic fuel
sensor harness. See “Installing the UFLS Harness” on page 44.
7. The fuel pump harness (TK supplied) will need to be routed through a
conduit or chase (see #6) from the fuel pump to the bottom of unit. The
harness needs to be attached to wires provided under the unit and also to
the fuel pump using the (TK supplied) butt splice connectors and heat
shrink. Four connections total. See“Installing the Fuel Pump and
Harness” on page 40.
8. The Ultrasonic Fuel Level Sensor harness (TK Supplied) will need to be
routed from the fuel tank to the bottom of the unit through the same
conduit or chase (see #6) as the fuel pump harness. The harness needs to
be attached to wires provided inside the control box and to the sensor at
the tank using the (TK supplied) butt splice connectors and heat shrink.
Six connections total. See “Installing the UFLS Harness” on page 44.
9. SmartPower™ units will come pre-wired with the power cable and
receptacle secured inside the unit with tie bands for shipment. The installer
will need to secure the receptacle under the roadside of the unit with (TK
supplied) hardware. The cable needs to be secured to the trailer wall with
the (TK supplied) cable clamps and screws. See “Installing the Power
Receptacle (Option)” on page 62. This does not apply to units with the
Remote Receptacle option.
10. Battery installation requires the removal of the roadside door and a bracket
to gain access the battery tray and cables. See “Installing the Battery” on
page 64.
11. The bottom panel and two top covers are shipped in separate cardboard
boxes and will need to be installed with (TK supplied) hardware. The top
fairing (if installed) should be removed if it interferes with maximum
trailer height restrictions. See “Installing the Top Covers, Top Fairing
and Bottom Pan” on page 66.
12. It may take a few attempts to start a newly installed unit for the first time
as the fuel pump primes itself, fills the fuel lines and filter, and
automatically bleeds air from the system. The fuel pump can also be
primed separately by using the SR-4 controller’s Interface Board Test
Mode - Run Relay Function. This function operates only the fuel pump
and primes the fuel system without cranking the engine. See “Priming the
Fuel Pump and Programming the Controller” on page 70.
13. All status light options now require the harness be routed into the control
box and connected directly to the controller board. See “Installing the
Status Light (Option)” on page 46.

Safety Precautions
The symbol appears next to a point that is particularly important:
DANGER: Addresses a circumstance that, if encountered,
will lead to death or serious injury
WARNING: Addresses a circumstance that, if encountered,
might lead to death or serious injury.
CAUTION: Addresses a circumstance that, if encountered,
may cause damage to equipment or minor injury.
DANGER: High voltage is present whenever the unit is
operating on either diesel or electric standby power. Take
precautions when servicing the unit as this high voltage can
cause death or serious injury.
DANGER: Never operate the unit with the discharge valve
closed because it could cause the compressor to explode,
causing death or serious injury.
DANGER: Never apply heat to a sealed refrigeration system or
container because it could explode, causing death or serious
injury.
DANGER: Fluorocarbon refrigerants, in the presence of an
open flame or electrical short, produce toxic gases that are
severe respiratory irritants capable of causing death.
DANGER: Be careful when working with a refrigerant or
refrigeration system in any enclosed or confined area with a
limited air supply (i.e., a trailer, container or the hold of a
ship). Refrigerant tends to displace air and can cause oxygen
depletion which may result in death by suffocation.
WARNING: Always wear goggles or safety glasses.
Refrigerant liquid, refrigeration oil, and battery acid can
permanently damage the eyes (see First Aid under
Refrigeration Oil).
WARNING: Keep your hands away from fans and belts when
the unit is running. This should also be considered when
opening and closing the compressor service valves.
WARNING: Make sure all mounting bolts are tight and are of
correct length for their particular application
WARNING: Never drill holes in the unit unless absolutely
necessary. Holes drilled into the unit may weaken structural
components. Holes drilled into electrical wiring can cause fire
or explosion.
WARNING: When using ladders to install or service
refrigeration systems, always observe the ladder
manufacturer’s safety labels and warnings. A work platform is
the recommended method for installations.

Safety Precautions (continued)
Battery Installation and Cable Routing Refrigerant
First Aid
FROST BITE: In the event of frost bite, the objectives of First Aid are to
protect the frozen area from further injury, to warm the affected area
rapidly and to maintain respiration.
EYES: For contact with liquid, immediately flush eyes with large amounts
of water and get prompt medical attention.
SKIN: Flush area with large amounts of lukewarm water. Do not apply
heat. Remove contaminated clothing and shoes. Wrap burns with dry,
sterile, bulky dressing to protect from infection/injury. Get medical
attention. Wash contaminated clothing before reuse.
INHALATION: Move victim to fresh air and use CPR or mouth-to-mouth
ventilation, if necessary. Stay with victim until arrival of emergency
medical personnel.
Refrigeration Oil
First Aid
NOTE: In case of eye contact, immediately flush with plenty of water
for at least 15 minutes. CALL A PHYSICIAN. Wash skin with soap and
water.
WARNING: Improperly installed battery could result in a fire or
explosion. A Thermo King approved battery must be installed
and properly secured to the battery tray.
WARNING: Improperly installed battery cables could result in
fire or explosion. Battery cables must be installed, routed and
secured properly to prevent them from rubbing, chaffing or
making contact with hot, sharp or rotating components.
WARNING: Do not attach fuel lines or any additional wiring
harnesses to the battery cables as this could cause an
electrical fire.
CAUTION: Do not connect other manufacturer’s equipment or
accessories to the Thermo King unit. This could result in
severe damage to equipment and void the warranty.
CAUTION: Set all unit electrical controls to the OFF position
before connecting battery cables to the battery to prevent unit
from starting unexpectedly and causing personal injury.
CAUTION: Always wear protective clothing, gloves and eye
wear when handling and installing batteries. Battery acid can
cause serious burns when exposed to eyes or skin. If battery
acid contacts skin or clothing, wash immediately with soap
and water. If acid enters your eye, immediately flood it with
running cold water for at least twenty minutes and get medical
attention immediately.
CAUTION: Always cover battery terminals to prevent them
from making contact with metal components during battery
installation. Battery terminals grounding against metal could
cause the battery to explode.
WARNING: Although fluorocarbon refrigerants are classified
as safe refrigerants, certain precautions must be observed
when handling them or servicing a unit in which they are
used. When released to the atmosphere in the liquid state,
fluorocarbon refrigerants evaporate rapidly, freezing anything
they contact.
WARNING: Avoid refrigeration oil contact with the eyes. Avoid
prolonged or repeated contact of refrigeration oil with skin or
clothing. Wash thoroughly after handling refrigeration oil to
prevent irritation.
