Swimming Pool Motors Installation Guide
This page contains general information on installation requirements of motors
Ventillation Adequate ventillation must be provide. The area below the pump should be dry and free of debris.
Motor should not be installed in direct sunlight or in temperatures above 104 degrees (F). Compensation should be allowed for higher temperatures, by using a larger horsepower than what is on the nameplate.
Moisture Keep area below and around pump dry and free of debris. Mount motor a level to avoid flooding of the motor
Altitude Altitudes in excess of 3,300 feet above sea level will cause a motor to operate at higher than normal temperatures. To compensate for this replace the motor, with the next higher available Horsepower.
Grounding

Safety is the utmost concern. Grounding of the pump to the ground is essential. This should be done in accordance with local building codes. Example: Ground the motor using the ground connection inside(usually green)the motor housing (terminal block). Bonding of the motor, should also be done using A # 10 wire. This is located on the outside of the motor.

Wire Size To Minimizew excessive voltage drop during startup. Make sure wirig is adewuate. Inadequate wiring will cause overheating and pre-mature failure of motors
