Horizontal Airfl Ow Units; Vertical Airfl Ow Units; Paperwork - Data Aire LCS Installation, Operation And Maintenance Manual

Note: There are many available unit confi gurations for the LCS. Be sure to identify the
unit type and style before installing. For instance there may be split condenser/condensing
sections requiring separate or shared power.
Note to Installing Contractor: Condensation formation and frequent humidifi er fl ush-
ing (when humidifi er is installed) are normal functions of this equipment. Drain connec-
tions must be made to ensure proper water removal. Unit will require drain connections
for condensate removal and water connections possibly for humidifi er (when installed)
makeup water, condenser water, chilled water and/or hot water. Installation of units above
equipment that could sustain water damage should be avoided.
1.3.1 Horizontal Airfl ow Units
All LCS units have horizontal airfl ow confi guration with a 29.5" tall evaporator section. Duct collars
are factory provided for the supply and return air.
Four threaded support rods must be securely attached to the building structure. Two fi eld provided
support channels connect to the pairs of threaded support rod. (See detail on drawing 536-900-100
shown on page 38.) 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.
1.3.2 Indoor Condensers and Condensing Units
Although most split air cooled systems have outdoor condensers or condensing units, indoor
condensers and condensing units are occasionally used. These 29.5" tall 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.
Typical installations have the condenser or condensing section physically near the evaporator,
especially since most have some 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 must be completed during installation. Also
included in the paperwork is a warranty/information packet that provides important wiring diagrams,
specifi c component literature, warranty registration card and other valuable paperwork, including a
copy of this Installation/Operation and Maintenance manual.
A manila (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 in warranty related services and in some cases void the warranty.
