Vertex™ Evaporative Condensers should be rigged and assembled as outlined in this bulletin. These procedures should be thoroughly reviewed prior to the actual rigging and assembly of the equipment to acquaint all personnel with procedures to be followed and to assure that all necessary equipment will be available beforehand.
1. Introduction Safety Adequate precautions appropriate for the installation and location of these products should be taken to safeguard the equipment and the premises from damage, and the public from possible injury. The procedures listed in this manual must be thoroughly reviewed prior to rigging and assembly.
Unit Weights Before rigging any unit, the weight of each section should be verified from the unit submittal drawing. Unit print weights include the final assembled unit with all accessories. Accessory weights (found on the respective drawing) can be deducted from the total weight.
2. Rigging & Assembly Rigging Refer to Table 1 for the recommended vertical dimension “H” from the lifting device to the spreader bar. In the event of extended lifts or where hazards exist, the lifting devices should be used in conjunction with safety slings placed under the unit. Casing Section or Single Basin Section Piece Lift...

Section Assembly Remove any motors or accessories shipped in the cold water basin. Rig the basin section. The rigging hook must be placed above the section’s center of gravity as detailed in Figure 1 and Figure 2. Wipe down the flanges with acetone to remove dirt or moisture which may have accumulated during shipment and storage. Install sealer tape on the mating flange of the bottom section to ensure an airtight seal between the top and bottom section.
Fasten the hardware between the coil casing and lower section per Figure 5. Lower the coil casing section the rest of the way onto the lower section, keeping mounting holes aligned. Figure 5. Fastening of Upper and Lower Sections Secure the hose connecting the sections of the pump discharge pipe with the hose clamps provided. On units with more than one casing, install the remaining casings using the same procedure as the first.
Controls Connections The controls wiring should be provided in a separate conduit from any power wiring. BAC recommends penetrating the control panel from the bottom or side panel observing standards. It is also recommended to use shielded wire to avoid interference. To control the Vertex™...
3. Optional Accessory Installation Bottom Water Outlet The bottom connection seal, Figure 8, is typical for all bottom remote sump outlets. Flange mounting hardware and gasket to be supplied by others. Bottom connection seal kit(s) ship in plastic tubs. Figure 8. Bottom Water Outlet Vertex™...
Offset Access Platform, Perimeter Guardrail and Ladder Overview External access platforms, perimeter handrails, ladders and ladder safety cages ship loose for field assembly and installation. Assembly and installation means and methods is dependent on the external access configuration selected. Please refer to the equipment submittal package for the selected external access configuration.

Offset Access Platform Assembly for 18’ Units Platforms for 18’ spans may ship in two sections, each roughly 10 ft in length, which should be joined prior to lifting and installing on the unit. Unbolt the splice plates from both sides of the platform, but DO NOT remove the plates from the support beam channel. Slide the loose plates to the locations shown in Figure 15, Detail A and B.
Page 17
Begin joining the platform sections by offsetting the sections from each other as shown in Figure 16. Figure 16. Platform Assembly Offset Slide the platforms until the crossmember cutout is aligned with the crossmember of the second section. Then slide the two sections together until the support beams are aligned, and the crossmember is seated into the cutout.

Follow all steps in Section “Typical Installation”. Install A-frame handrail section and toeboard. See Figure 14 and Figure 21. Detail A – Field Installed A-Frame Handrail Section Figure 21. Platform and A-Frame Handrail Section Installation Detail B – Fastening A-Frame Handrail Section Vertex™...
Gap Cover Plate Installation After platform installation is complete secure platform gap cover plates (PCC) to platform base using 5/16” tappers and 1/4” x 2” self-tapping screws provided. Secure coil casing section gap cover plate (FAT) to coil casing section using 1/4” x 2”...
Ladder Safety Cage If the safety cage is shipped in multiple pieces assemble the bottom flared section to the upper safety cage section. Secure with supplied hardware. See Figure 23. NOTE: Safety gates are provided for all handrail openings, and all components are designed to meet OSHA requirements.
Page 22
Bolt the safety cage to the ladder using flat washers and locknuts. Orient all fasteners with bolt heads inside safety cage. See Figure 24, Detail A through D and refer to Table 2 for the quantity of bolting locations for different safety cage heights.
Automatic Bearing Greasers (Optional for BALTIDRIVE ® Power Train Units Only) Verify the mounting brackets are factory installed Fill the extended lube lines with BAC compatible water resistant grease using a manual grease gun. See the “Fan Shaft Bearings” section of the Vertex™ Evaporative Condenser Operation & Maintenance Manual available on www.BaltimoreAircoil.com.
Heater Control Panel Carefully plan the location of the control panel. Measure the factory supplied probe cord length. Do not attempt to change the cord length. NOTE: The heater control panel should be within sight of the heater if a disconnect switch option is selected After selecting the installation site, mount the control panel with four 5/16"...
