Introduction
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.
Anchoring
Seven-eighths inch (7/8”) diameter holes are provided in the bottom flange of the basin
section for bolting the unit to the support beams. Refer to the suggested support drawing
included in the submittal for location and quantity of the mounting holes. The unit must
be level for proper operation. Anchor bolts must be provided by others. The IBC rating is
only certified with standard anchorage locations. Using alternate anchorage locations or
alternate steel supports will void any IBC wind or seismic ratings. Contact your local BAC
Representative for details.
Nitrogen Charge of Condenser Coils (PCC Only)
As of June 2017, condensers shipped from the factory are charged with nitrogen to
15 psig. Relieve the pressure then cut and bevel coil connections in accordance with
generally accepted industrial practices. If the unit arrives without the holding charge, it
is reccomended a test be placed on the coil before installing. If you have any questions,
contact your local BAC Representative.
Cold Weather Operation
These products must be protected by mechanical and operational methods against damage
and/or reduced effectiveness due to possible freeze-up. Refer to “Cold Weather Operation”
in the PFi and PCC Operation & Maintenance Manual on www.BaltimoreAircoil.com, or
contact your local BAC Representative for recommended cold weather operation strategies.
Location
All evaporative cooling equipment must be located to ensure an adequate supply of fresh
air to the fans. When units are located adjacent to walls or in enclosures, care must be
taken to ensure the warm, saturated, discharge air is not deflected and short-circuited
back to the air intakes.
Each unit must be located and positioned to prevent the introduction of discharge air
into the ventilation systems of the building on which the unit is located and of adjacent
buildings. For detailed recommendation on BAC equipment layout, see our website at
www.BaltimoreAircoil.com or contact your local Representative.

Multi-Cell Unit Assembly
Multi-Cell Unit Installation
Refer to the submittal unit print for the proper orientation of each cell. All multi-cell units
have the cell number and “face” stenciled on the outer basin wall of each lower section,
as well as match marks to show how the cells are to be mated. Multi-cell unit installations
may use flume boxes to equalize the water level in the basin of each cell. Follow directions
in “Flume Box Installation” below for detail on their installation.
Multi-Cell Unit Assembly
1. Attach the first cell’s lower section to the support and then fasten the first cell’s upper
section to the first cell’s secured bottom section. For units shipped in two sections per
cell, follow the instructions on page 5. For units shipped in three sections per cell,
follow the instructions on page 6.
2. Each subsequent cell should be assembled adjacent to its final location, and then
properly positioned next to the previous cell. Ensure spacing between the cells at the
bottom flange is 3” on Face A-B, 5” on Face C-C.
3. PCC quad cell units come with air bypass panel windows on Face C as shown in
Figure 11. These windows facilitate removal of the inner most lift shackle after the
final cell is installed. The window panels FAB are shipped loose inside the cold water
basins and should be installed using the supplied flat butyl sealer tape (BAC part #
554000) and 5/16” self-tapping screws after the final cell is in place and the lift
shackles are removed.
4. Some PFi units come furnished with a flume box. If they do, use the flume box
assembly procedure outlined on page 10 to connect the basins of multi-cell units.
NOTE: On quad cell installations,
it is suggested that the cells
subsequent to the first cell have the
upper and lower sections assembled
on the support foundation adjacent
to the final mounting locations. This
will allow space for securing the
upper and lower sections of each
cell. Move the subsequent cell(s) to
their final position using the lifting
devices on the casing.

2. Wipe down the mating surface on the outer, protruding end of the flume box and apply
a layer of flat butyl sealer tape (BAC Part #554000) around the face of the flange over
the centerline of the holes. Do not overlap or stretch too thinly at the corners. When it
is necessary to splice the butyl sealer tape, be sure to press the two ends together to
form a smooth, continuous strip. See Figure 12.
3. Apply a second layer of butyl sealer tape over the first layer following the same
procedure.
4. Assemble Cell #2 just adjacent to its final location. Wipe down the mating surface
adjacent to the flume box opening to remove any dirt or moisture.
5. Position Cell #2 on unit supports. Using drift pins to ensure alignment, draw
Cell #2 tight against the flume box, ensuring that the spacing between the cells at the
bottom basin flange is 3” on Face A-B, 5” on Face C-C.
6. As illustrated in Figure 13, insert 3/8” x 1 1/4” thread cutting screws in each
hole from the flume box into the basin wall and tighten. For basins with TriArmor®
Corrosion Protection System and stainless steel basins, bolt strips are provided in
lieu of individual thread cutting screws. For TriArmor basins only, a backing plate is
provided and must be installed inside of Cell #2, as seen in Figure 14. Secure using
the provided hardware.
NOTICE: If the backing plate is not
properly installed, the TriArmor®
