Locating the Components

Volvo L-4 Installation Guidelines

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.

Dometic, a global leader in mobile living solutions, has produced two standout models in their lineup: the Dometic VN670 and VN630. These innovative portable refrigerators are designed for those who demand high performance and reliability while on the go, whether for camping, RV-ing, or simply enjoying the great outdoors.

Both the Dometic VN670 and VN630 feature an ultra-efficient compressor cooling technology that provides fast and consistent temperature control, even in extreme environments. This ensures that food and beverages remain fresh and cold, catering to the needs of campers and travelers alike. With the ability to operate efficiently on both AC and DC power sources, they are versatile enough for use in vehicles, boats, or off-grid setups.

The VN670 offers an impressive capacity of 65 liters, making it ideal for larger groups or extended trips. It features a removable basket that allows for easy organization of contents, and multiple storage compartments ensure efficient space utilization. Meanwhile, the VN630, with its 30-liter capacity, is perfect for solo travelers or couples, striking a balance between size and portability without sacrificing cooling performance.

Both models come equipped with a digital control panel, providing intuitive operation and easy temperature adjustments. The inclusion of Bluetooth technology in the VN670 allows users to monitor and control settings remotely via a smartphone app, adding a layer of convenience for tech-savvy adventurers.

Another defining characteristic of these models is their robust construction, designed to withstand the rigors of outdoor use. The exteriors are built from durable materials that are resistant to shocks and impacts, ensuring longevity even in challenging conditions. Additionally, both models feature low-energy LED lighting, enhancing visibility when accessing the contents in dimly lit settings.

One of the key features for energy-conscious users is the energy-saving mode integrated into both units. This function optimizes performance based on the ambient temperature and the number of contents stored, minimizing energy consumption without compromising cooling effectiveness.

The Dometic VN670 and VN630 embody the perfect blend of advanced technology, practical design, and durability. With these portable refrigerators, outdoor enthusiasts can enjoy the convenience of a home-style cooling solution wherever their adventures take them.
