Platform and Ladder Installation
Remove platform and ladder assembly from cold
water basin. Hang pre-assembled platform by
inserting top guide pins into fan deck notches
(shown in Figure 15, Detail A). Secure with
tappers. Assemble lower platform clamps and
secure to side of tower, tightening nuts and
bolts shown in Figure 15, Detail B.
Optional Factory Pre-Wired Terminal Box
BAC offers an optional terminal box with factory
pre-wiring for PT2 models 0412, 1009, 1012 and
1212. When this option is ordered, the tower fan
motor(s) and vibration cutout switch are wired at
the factory (through flexible conduit) and
terminated on the outside face of the BAC unit in
a clearly marked, 304 Stainless Steel, Nema 3R
terminal box (see Figure 16 for the exterior
location of the box on the tower).The box
includes a cover plate, which once removed
reveals an easy-to-follow wiring diagram and
modular terminal blocks. Remove the cover
plate, and install the collar (which ships in the
tower’s cold water basin) which has
pre-punched conduit holes. Wiring from the
terminal blocks to the unit controls is sized,
provided and installed by others. After the
controls are wired, reinstall the cover plate on
the terminal box.
Sloped Ladder Installation
Remove ladder from cold water basin. Slide the
ladder bracket assembly (attached to side of
ladder) into the ladder mounting guides located
on the side of the tower (Figure 16). Align the bolt
holes and install the hardware through the
ladder mounting bracket and ladder mounting
guides, tighten.
