1. Warnings and Cautions Safety Precautions : This unit contains rotating equipment that can cause severe personal injury or death upon contact. Never remove or step on a fan guard grill, subject the fan guard grill to load, or place any objects on the fan guard grill.
BAC units are typically installed immediately after shipment, and many operate year-round. However, if the unit is to be stored for a prolonged period before installation or remain in an unused state for a prolonged period after installation, certain precautions should be observed. Refer to Prolonged Outdoor Storage details in Section 2.
Read all warnings, cautions and notes. Pre-Rigging Checks BAC TrilliumSeries™ adiabatic coolers are factory assembled to ensure uniform quality with minimum field assembly. For each unit, only one lift is required. For the dimensions and weights of a specific unit or section, refer to the submittal drawings.
Supporting steelwork and anchor bolts are not provided by BAC and must be furnished by others. BAC recommends 3/4” diameter, SAE J429 Grade 5, ASTM A325 Type 1 or equivalent anchor bolts. Beams should be selected in accordance with accepted structural engineering practices.
For detailed recommendations, see the Layout Guidelines available on BAC’s public website. Rigging Summary 1. The equipment arrives on site by truck. A crane must always be used to unload the unit from the truck.

NOTE: BAC units are typically installed immediately after shipment, and many operate year-round. However, if the unit is to be stored for a prolonged period of time either before or after installation, certain precautions should be observed.
Preparation After Prolonged Storage Keep in mind that start-up procedures after long periods of storage are just as important as pre-shutdown procedures. Follow instructions in the TrilliumSeries™ Adiabatic Cooler – TRF Operation & Maintenance Manual shipped with the unit and also available at BaltimoreAircoil.com. Be especially thorough with cleaning and inspection prior to start-up.
3. Installation Piping Guidelines When piping the unit, route the water pipes down or to the side so that there is a clear landing area in front of the unit for accessing the control panel and access hatch(es) in compliance with NEC regulations. NOTE: Field piping must not be supported by the unit inlet or outlet connections.

Water Connection Size for TRF Units Installation of Leaving Fluid Temperature Sensor A leaving fluid temperature sensor is supplied on units configured as self-contained and is shipped inside the electrical panel together with a socket for installation in the return pipe.
Flange Coil Connections Units configured with flange coil connections are supplied with class 150 floating flanges. Refer to unit submittal drawings for flange size. For shipment, sheet metal blanks are zip tied to floating flanges to secure flanges and to seal off the coil connection. Remove zip ties and sheet metal blank prior to installation.
It is recommended to use shielded wire to avoid interference. BAC offers the following options to control the TrilliumSeries™ adiabatic cooler. Check the submittal package for configuration settings and wiring diagrams.
