Move unit to installation area. Remove unit from ship-ping package. Do not handle by controls or damperextension rod.2. The unit has factory-installed brackets.3. Suspend units from building structure with straps, rods,or hanger wires. Secure the unit and level it in eachdirection.Step 2 — Make Duct Connections1. Install supply ductwork on each of the unit inlet collar.Check that air-supply duct connections are airtight andfollow all accepted medium-pressure duct installationprocedures. (Refer to Tables 3-5 for pressure data.)2. Install the discharge ducts. Fully open all balancingdampers.A straight length of inlet duct is not required before the unitinlet. Ninety-degree elbows or tight radius flexible duct im-mediately upstream of inlet collar should be avoided.Step 3 — Install Sensors and Make Field WiringConnections — Electric Analog or DDC (DirectDigital Controls)Refer to specific unit dimensional submittals and control ap-plication diagrams for control specifications. All field wiringmust comply with National Electrical Code (NEC) and localrequirements. Refer to the wiring diagram on the unit for spe-cific wiring connections.A field-supplied transformer is required if the unit was notequipped with a factory-installed transformer. See Fig. 4.NOTE: Refer to wiring diagram attached to each unit for specificinformation on that particular unit.Unit airflow should not be set outside of the range noted inFig. 4-6 and the performance data section of this document.
