Tips For a Successful Installation
Before Beginning the Installation Recommendations
IImmppoorrttaanntt:: Proper installation of each component onto the vehicle is critical! Refer to the Thermo King TriPac
Installation Standards Guide (TK 564 8) before beginning the installation. Adhering to the installation
standards will help assure the components are installed correctly and the system operates as designed. It is
the responsibility of the installer to follow these standards.
• Review component location iagram an iscuss with the customer where each component will be installe on the
truck.
• Verify tools an special equipment require for the installation are available an in goo working con ition.
• Open all installation kits an inspect the contents before beginning installation.
• It is recommen e that one person performs the installation of all the components oouuttssii ee the sleeper while a
secon person installs all the components iinnssii ee the sleeper. This will help minimize any amage to the sleeper’s
interior from grease, irt, etc.
Truck’s Alternator Requirements
• The truck’s engine must be fitte with an upgra e alternator of 270 amps or more an with upgra e alternator
wiring of OEM approve esign.
Truck’s Battery Recommendations
• It is important not to allow the truck’s batteries to become ischarge uring the APU installation process. A battery
charger shoul be connecte to the batteries while the installation is in process or shut the truck’s battery power
supply completely off using the OEM main battery isconnect switch if available.
• An alternative metho is to shut the truck’s battery power completely off using the OEM main battery isconnect
switch if available.
• For TriPac Envi ia bbaassee lleevveell ppeerrffoorrmmaannccee::The truck’s battery box must have four 12V c batteries connecte in
parallel to provi e 12V c output.
• For TriPac Envi ia ooppttiimmuumm lleevveell ppeerrffoorrmmaannccee::Thermo King recommen s the truck’s batteries be upgra e to
Thermo King NXT 1150 CCA absorbe glass mat (AGM) batteries.
APU Battery Requirements
TriPac Envi ia units are shippe with Thermo King NXT AGM batteries fully charge an rea y to use. Batteries that are
kept in stock shoul not require charging for 2 years if kept below 77 F (25 C). Batteries shoul be charge when the
open circuit voltage (OCV) falls below 12.50 volts.
To charge the NXT AGM battery, use the following gui elines:
1. Verify the output voltage of your battery charger is capable of maintaining 14.1 to 14.7 charging voltage. The
recommen e charging voltage range for the NXT AGM battery is 14.1 to 14.7 volts. Voltages are to be measure at
the battery terminals with the battery connecte to the charger.
IImmppoorrttaanntt:: Never exceed 15 volts when charging the NXT AGM battery. Exceeding 15 volts will cause pressure
relief valves to open and out-gas hydrogen and oxygen from inside the battery. This will shorten the life
of the battery and could lead to premature battery failure.
2. Battery chargers with the battery type output setting shoul be set to AGM type battery.
DDOO NNOOTT set the output type to gel cell or maintenance free settings.
3. Determine if your battery charger is an automatic or manual charger. Manual battery chargers must be closely
monitore uring the charge perio an for this reason an automatic battery charger is preferre over a manual
charger.
a. Automatic battery chargers either charge up to a preset voltage an shut off, or charge to a present voltage an
then switch to a trickle charge mo e. Either one of these battery chargers is acceptable: however, the automatic
charger that shuts off may not fully charge the battery.
b. Manual battery chargers will have manual controls for setting the charge amperage rate. The charge amperage
rate will remain the same until the battery charger is manually shut off.
