Tips For a Successful Installation
Before Beginning the Installation Recommendations
I I m m p p o o r r t t a a n n t t : : Proper installation of each component onto the vehicle is critical! Refer to the Thermo King TriPac
Installation Standards Guide (TK 56498) 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 diagram and discuss with the customer where each component will be installed on the
truck.
•
Verify tools and special equipment required for the installation are available and in good working condition.
•
Open all installation kits and inspect the contents before beginning installation.
•
It is recommended that one person performs the installation of all the components o o u u t t s s i i d d e e the sleeper while a
second person installs all the components i i n n s s i i d d e e the sleeper. This will help minimize any damage to the sleeper's
interior from grease, dirt, etc.
Truck's Alternator Requirements
•
The truck's engine must be fitted with an upgraded alternator of 270 amps or more and with upgraded alternator
wiring of OEM approved design.
Truck's Battery Recommendations
•
It is important not to allow the truck's batteries to become discharged during the APU installation process. A battery
charger should be connected to the batteries while the installation is in process or shut the truck's battery power
supply completely off using the OEM main battery disconnect switch if available.
•
An alternative method is to shut the truck's battery power completely off using the OEM main battery disconnect
switch if available.
•
For TriPac Envidia b b a a s s e e l l e e v v e e l l p p e e r r f f o o r r m m a a n n c c e e : : The truck's battery box must have four 12Vdc batteries connected in
parallel to provide 12Vdc output.
•
For TriPac Envidia o o p p t t i i m m u u m m l l e e v v e e l l p p e e r r f f o o r r m m a a n n c c e e : : Thermo King recommends the truck's batteries be upgraded to
Thermo King NXT 1150 CCA absorbed glass mat (AGM) batteries.
APU Battery Requirements
TriPac Envidia units are shipped with Thermo King NXT AGM batteries fully charged and ready to use. Batteries that are
kept in stock should not require charging for 2 years if kept below 77 F (25 C). Batteries should be charged when the
open circuit voltage (OCV) falls below 12.50 volts.
To charge the NXT AGM battery, use the following guidelines:
1. Verify the output voltage of your battery charger is capable of maintaining 14.1 to 14.7 charging voltage. The
recommended charging voltage range for the NXT AGM battery is 14.1 to 14.7 volts. Voltages are to be measured at
the battery terminals with the battery connected to the charger.
I I m m p p o o r r t t a a n n t t : : 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 should be set to AGM type battery.
D D O O N N O O T T 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
monitored during the charge period and for this reason an automatic battery charger is preferred over a manual
charger.
a. Automatic battery chargers either charge up to a preset voltage and shut off, or charge to a present voltage and
then switch to a trickle charge mode. 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.
