Electrical Wiring and HMI Controller Installation Requirements
I I m m p p o o r r t t a a n n t t : : See "Electrical Standards" in Section 10 of the Thermo King TriPac Installation and Standards Guide (TK
56498). THESE STANDARDS MUST BE FOLLOWED!
•
Electrical wiring should be installed and routed in such a way as to allow for vibration and movement of the cab.
THEY SHOULD NEVER BE STRETCHED TIGHT!
•
Always keep electrical wiring from rubbing or chafing against sharp metal objects, rotating components or hot
objects.
•
All electrical wiring should be neatly routed and secured with band wraps or clamps.
•
Do note route or bundle 110Vac wires together with 12Vdc wires.
•
Do not route electrical wires, harness or battery cables together with fuel lines.
•
Excess length of battery cables should be cut off to reduce voltage drop.
•
Superlube (203-524) or equivalent should be applied to all electrical connections.
•
All main power and ground accessory connections must be installed directly on top of the truck's battery terminal
posts and tightened securely. DO NOT INSTALL UNDER OEM BATTERY CABLES!
D2 / D4 Heater Installation Requirements (Units with Heat Option)
I I m m p p o o r r t t a a n n t t : : See "Heater Installation Standards" in Section 7 of the Thermo King TriPac Installation and Standards
Guide (TK 56498). THESE STANDARDS MUST BE FOLLOWED!
•
Determine the best location of the heater inside the sleeper, typically under the bunk. Allow clearance for
dismantling for service.
•
Install heater so it will maintain a minimum distance of 2.00 inches (50.8 mm) from any heat sensitive or flammable
material.
•
The heater must only be mounted on a flat horizontal surface.
•
Heater must be installed flush with the floor pan (i.e. sheet metal, fiberglass, etc.) to ensure proper sealing of the
mounting plate and gasket.
•
All edges of access holes made in fiberglass and wood composite floors must be sealed correctly with (installer
supplied) fiberglass cloth and resin.
•
Outside air intake and exhaust hoses must be installed correctly for the heater to operate safely.
•
Exhaust hose should be mounted slightly downwards to help drain off condensation.
•
Install exhaust hose so it will maintain a minimum distance of 2.00 inches (50.8 mm) from any heat sensitive or
flammable material.
•
Inside air inlet and outlet ducts must be installed correctly for the heater to operate safely.
•
Pulse type fuel pump outlet must be installed at a 15 to 35 degree angle up from horizontal to operate correctly.
•
Fuel pickup tube must be installed correctly in the fuel tank or the heater will not operate.
•
Fuel line from the pickup tube to the fuel pump to the heater should be routed at a continuous rise. Use a hose cutter
or sharp knife to cut plastic fuel lines. Do not use a wire cutter as this will pinch the plastic fuel line closed.
•
Do not route electrical wires, harness or battery cables together with fuel lines.
•
BEFORE operating the heater, the fuel lines must be bled of air using the Heater Priming Harness (204-1144) or
damage to the fuel pump will result.
•
The Diagnostic Code Reader (204-1143) must be used to setup and operate the heater in the run-in mode.
