Dometic ACCD7 Leaflet

Page of 2
Dometic auxiliary remote truck air 
conditioning systems are designed 
to cool or heat 
the cab and sleeper 
without running the truck’s diesel engine, 
saving fuel and preserving the environment. 
The systems run on 120VAC electricity, which 
is supplied by a shorepower connection,  
an auxiliary power unit (APU) or a battery-
based system. Models are available in 7,000 
BTU/Hr, 10,000 BTU/Hr and 14,000 BTU/Hr 
capacities. Electrical strip heating options 
include 1, 1.5, 2, 2.5, 3 and 4 KW, and can be 
specified as either single or two-stage. It can 
also be integrated with a diesel fuel heater, 
using the same Dometic Qt Control/Display.
The system consists of separate inside 
(evaporator) and outside (condenser) 
sections connected by flexible refrigerant 
lines. Designed for the harsh trucking 
environment, the units are vibration and 
corrosion resistant, and are backed by more 
than 40 years of mobile air conditioning 
experience. A digital thermostat controls 
the system and is ordered separately. 
Government-approved environmentally 
friendly R-417A refrigerant (HFC) is used.
The ACC condenser section has a highly 
efficient, lightweight, compact all-aluminum 
condenser and a 24VDC cooling fan within 
a powder-coated aluminum housing. To 
save space and reduce noise, it is mounted 
outside, typically under the cab.  
 
 
 
The EHC  
inside evaporator unit consists of a 
compressor, evaporator coil, electric  
heat strip and a blower in an aluminum 
enclosure with a deep condensate  
drain pan. A cooling only unit (no heat 
strip) is also available. This compact unit is 
designed to be installed under a bunk, or in 
the bottom of a closet or cabinet. An efficient 
rotary compressor was selected for its 
quiet operation, and the enclosure further 
minimizes noise in the sleeper. A built-in 
electric heat strip provides heat during cold 
weather. The strong squirrel-cage blower 
moves the cooled or heated air to one or 
more discharge grilles through insulated 
flexible or fixed ducts. 
The condenser, evaporator and lineset are 
all charged at the factory with the proper 
amount of refrigerant. Reuseable quick-
connect fittings are specified so that no 
special refrigerant handling equipment is 
required. Wire harnesses are waterproof and 
polarized for each plug-and-play installation.
A sleek and attractive cover for the 7,000 
BTU Day Cab interior system is available 
to provide protection to the unit while 
muffling sound for a more comfortable 
cab environment. The Dometic Qt Control/
Display can be mounted directly onto the  
top of the cover, allowing easy access for  
the driver.
