Caution

Warning

Installation

Fasteners and components provided by others that are to be at- tached to the tower must be compatible with the cooling tower materials—i.e. fasteners in a stainless steel cold water basin must be stainless steel.

6.Attach process fluid supply and return piping to the coil. Field piping connection is an NPT male connection at the coil. A welded connec- tion requires removing the threaded portion of the coil.

For welded connections protect adjacent areas from excessive heat and sparks or damage may occur.

7.Wire motor(s) and recirculation pump(s) in accordance with wiring diagram.

For maintenance/safety purposes, SPX Cooling Technologies recom- mends a lockout type disconnect switch for all mechanical equipment. In addition to a disconnect switch, the motor should be wired to main power supply through short circuit protection, and a magnetic starter with overload protection.

Motor Wiring

Wire motor leads as shown on the motor nameplate matching the supply voltage. Do not deviate from the motor nameplate wiring.

Either of following symbols may be shown on the motor nameplate – Δ, Δ Δ, Y, or YY. These symbols represent how the motor is constructed on the inside and in no way have anything to do with a Delta or Wye electrical distribution system serving the motor.

When using a starter:

•Set motor overload protection to 110% of motor nameplate amps. This setting allows the fan motor to operate during cooler weather. During cooler weather it is common for the motor to draw 6 to 10% higher than nameplate amps. High amps are common during tower commissioning when the tower is dry and the ambient air temperature is cool.
