LOCATING THE COMPONENTS
The Dometic remote auxiliary air conditioning system consists of two basic components: an outside condensing unit, which contains the condenser and an exhaust fan, and an inside unit, which contains the compressor, heater, evaporator and blower (CHEB). The two units are connected by precharged refriger- ant lines with quick-connect fittings.
For the Volvo L-4 chassis, we recommend placing the CHEB unit in the passenger-side luggage compart- ment alongside the Volvo factory air conditioning unit (Fig. 1), and mounting the condensing unit either hori- zontally under the truck (Figs. 2a-2b), with exhaust air blowing down toward the road, or vertically on the back wall of the sleeper. Refer to the primary instal- lation manual for important guidelines not included here.
Use the template to position the CHEB unit correctly (Fig. 3). Place the template with the “edge of the unit” 1-1½" from the factory HVAC unit mounting foot. The “edge of the unit” line with the notations for the quick connections should be nearest the bunk wall. The line of the “edge of the unit” should be approxi- mately 5" from the bunk wall. Mark for the two quick connect holes 3½" off the “edge of the unit” using the construction lines (Fig. 4). Follow the step-by-step procedures in the installation manual for mounting the unit and drilling holes.
