Dometic EHCEQ7* - Manual

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. Electric heat-strip options
include 1, 1.5, 2, 2.5, 3, and 4 KW, and can
be specified as either single or two-stage.
The system can also be integrated with a
diesel-fuel heater, using the same Dometic
Qt Control/Display (Espar only).
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. The system consists of
separate inside (evaporator) and outside
(condenser) sections connected by flexible
refrigerant lines. Government-approved,
environmentally friendly R-417A refrigerant
(HFC) is used.
The 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 or on the
back of the sleeper.
The 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 for installation 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 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.
