Most applications will allow for the condenser discharge air to blow out into the ceiling space and no
ducting is required. The ceiling space must be large enough to dissipate the rejected heat. Plenum
space temperature should not exceed 95
o
F. If ducting is required the additional static imposed by
ductwork on the air intake and/or discharge should not exceed 0.3”. In some applications a factory
provided low ambient damper is used at the condenser air intake. The air intake is modifi ed from its
normal grilled openings to a single 15” x 17” duct collar.
1.3.3 Horizontal Airfl ow Units
Ductwork is connected to factory provided duct collars on the supply and return air openings. Four
threaded support rods must be securely attached to the building structure. Raise the evaporator
section with an appropriate lifting device. Attach washers, nuts and jam nuts to each threaded rod.
Tighten the nuts so the weight is supported evenly by the four rods and the unit is level.
Note some options call for a combination of vertical and horizontal airfl ow confi guration.
In that case, the 5” plenum assembly described above is necessary.
1.3.4 Indoor Condensers and Condensing Units
These sections are to be mounted in the same manner as the evaporator sections using four
threaded rods. Air cooled condensers or condensing units have factory provided duct collars on the
supply and intake air openings as appropriate. Water cooled condensing sections have no airfl ow
connections.
Typical installations have the condenser or condensing section physically near the evaporator,
especially since most have shared electrical line power. The mounting of these sections is independent
of the evaporator mounting. The same service and maintenance clearance requirements apply to
these units as well.
1.4 Paperwork
Each Data Aire unit ships with a start-up sheet that should be completed during installation. Also
included in the paperwork is a warranty/information packet that provides important wiring diagrams,
specifi c component literature, warranty registrations cards and other valuable paperwork, including
a copy of this Installation/Operation and Maintenance manual.
A yellow tag is attached to the outside panel to indicate articles that may have been packaged and
shipped loose within the unit cabinet. Typically this would be a condensate pump and other loose
components that are not factory mounted.
It is the responsibility of the installing contractor to return the start-up sheet and warranty
registration card to Data Aire for proper activation of the unit warranty. Failure to do so
may cause delays and in some cases void the warranty.
1.5 Storage
Your Data Aire equipment comes ready for immediate installation. In some instances it may be
necessary to store the equipment for a period of time. If you must store the equipment it should be
done in a dry area, out of the weather, protected from freezing temperatures, protected from damage
by other equipment in storage or transportation equipment, never stacked, and avoid frequent
relocation.
