Dometic offers two basic types of air conditioning systems:
• Patented split systems
• Self-contained package units
In the majority of cases, split systems are preferred, but there may be occasions when a package unit is
desirable.
Dometic’s patented split systems consist of two separate modules. The outside condenser/fan (CF) unit is
bolted horizontally under the truck or vertically to the back of the cab or sleeper. The compressor/heater/
evaporator/blower (CHEB) unit is mounted inside the truck, usually under a bunk or seat, or in a side storage
locker. The two units are connected by reusable precharged refrigerant linesets with quick-connect fittings at
both ends. The system is designed so that both units automatically charge to the correct refrigerant pressure
as soon as the linesets are connected. No special tools are required.
The self-contained unit is designed to be wholly mounted inside the truck. All of the air conditioning
components, including the compressor, condenser, evaporator, blower, power supply and optional heater are
mounted on a single chassis with an aluminum cover. The closed refrigerant loop is precharged and sealed
at the factory. Air is discharged from the condenser to the outside air through cutouts in the floor.
Both types of systems can be ordered with built-in electric heat modules, or can be used with a diesel-fired
heater under control of the same thermostat.
The Dometic HVAC systems use a standard digital thermostat/display unit. Operation is intuitive and easy,
with up and down arrows to adjust the setpoint and fan speed. The installation kit will also include ducts,
grills, condensate drains and electrical wiring.
Each approach offers advantages and disadvantages. A self-contained unit is simpler to install and maintain,
since it does not have any external refrigerant lines. It is also less expensive than a split system of the same
BTU capacity. On the other hand, it takes more interior space, and it requires cutting holes in the floorboard
for air to flow to and from the condenser.
A split system, on the other hand, has more installation flexibility and uses less interior space. It also is
quieter, since the condenser is located outside the truck.
Both types of air conditioning systems can include built-in electrical heat modules. The heat is blown through
the same ducts and grills and controlled by the same thermostat. They can also be used in conjunction with
a diesel-fired heater if desired, under control of the same thermostat.
Whichever type of system you select, it will come with ducts, grills, condensate drains, thermostat controls
and electrical wiring.
