A/C Duct Installation

A/C Vent Locations

N N o o t t e e : : See "Evaporator Air Discharge Ducts and Vents Installation Standards" in Section 6 of the Thermo King TriPac
Installation Standards Guide (TK 56498). THESE STANDARDS MUST BE FOLLOWED!
The evaporator is equipped with two air discharge outlets to attach the supplied flexible air ducts. The ducts will be
attached to plastic air vents that should be located and installed to provide maximum air circulation in the sleeper.
Suggested locations of the air vents:
• M M E E D D I I U U M M (above lower bunk level)
• H H I I G G H H (above upper bunk level)
N N o o t t e e : : A/C air ducts and vents are typically routed and installed through closets or storage compartments.
I I m m p p o o r r t t a a n n t t : : Extreme care should always be taken when drilling holes in the various types of material found in sleepers
such as plastic, steel, aluminum, and upholstery.
To maximize APU efficiencies, the back flow damper kit (710676) must be installed when connecting the TriPac's air conditioning discharge hose
(s) directly into the truck's OEM HVAC duct(s). The damper will prevent the TriPac's air from back flowing into the OEM HVAC housing. Failure to

Installation Procedures

Special Tools Required
Drill Motor
4-1/4" diameter Hole Saw
(for installing plastic A/C louver vents and for routing
ducts through compartment walls)
1. Find an appropriate location for the A/C vents and drill 4-1/4" diameter holes.
2. Attach one end of the flexible air duct to one of the air discharge outlets of the evaporator and secure with supplied
hose clamps
3. Route the flexible air duct through the A/C vent hole, cut excess duct as needed.
4. Unsnap rotating outer louver assembly from the mounting base.
5. Attach to flexible air duct to the end of the louver base with band wraps.
6. Push the mounting base back into 4-1/4" mounting hole and secure with supplied screws.
7. Reinstall rotating outer louver assembly back into the mounting base and verify that it rotates freely.
8. Install the second A/C vent in the same manner.
9. Verify flexible ducts are installed and routed with smooth bends and no kinks to provide maximum airflow.
10. Secure flexible ducts with large band wraps to prevent excess movement.
