PT2-0709, 0809 and 0812 Motor Installation (Figures 12 and 13):
Attach lifting strap to the motor base eyelet and remove the motor and motor base assembly from the
cold water basin shipping location. The motor assembly remains vertical to maintain proper
alignment during installation. Lift assembly into position next to access door. Attach the assembly to
the unit using the six supplied studs and hardware. Install power band and check sheave alignment.
Finally, tension the power band. For correct tensioning specifications and procedures, refer to the
Operation and Maintenance Manual.
Note: All other PT2 models have fan motor mounted and tensioned at the factory
Warning: Ensure that the fan guard is properly installed prior to commencing operation
Installation of the Optional Side Outlet Depressed Sump Box
The optional side outlet depressed sump box allows a cooling tower water outlet connection to be
piped from underneath the unit in four possible directions, 90˚ apart. The piping connection is a bolt
circle designed to fit an ASME Class 150 flat flange with a full-face gasket.
To install the side outlet depressed sump box, follow the steps below:
1. Wipe the edges around the opening in the cold water basin to remove any dirt or moisture
that may have accumulated during shipment. Apply a layer of 1/8” x 1” butyl sealer tape
around the opening in the basin over the
centerline of the holes. Do not stretch the
sealer too thinly or overlap at the corners.
When it is necessary to splice the sealer, be
sure to press the two ends together to form a
smooth continuous strip. Apply a second layer
of sealer tape over the first layer following the
same procedure. Refer to Figure 14
2. Insert the sump box assembly into the opening
in the cold water basin and attach it to the
basin with 3/8” x 1” bolts, nuts, flat washers,
and lock washers as shown in Figure 14,
Detail A
3. Place the suction strainer over the opening
