NOTE: There are many available unit configurations for the Large Ceiling
Systems, therefore; be sure to identify the unit type and style before installing.
For instance there may be split condenser/condensing unit sections requiring
separate or shared power.
Note to Installing Contractor: Condensation formation and frequent
humidifier flushing (when humidifier is installed) are normal functions of this
equipment. Drain connections must be made to ensure proper water removal.
Unit will require drain connections for condensate removal and water
connections possibly for humidifier (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.
Horizontal Airflow Units
All LCS units have horizontal airflow configuration with a 29 1/2” (750 mm) tall evaporator section. Duct
collars are factory provided for the supply and return air duct flanges.
Installing/Mounting
Four (4) threaded support rods must be securely attached to the building structure. Two field provided
support channels connect to the pairs of threaded support rod. See Figure 1 Typical Installation
Methods for typical LCS installation method.
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.
