Motor Load

assembly identification number (see Figure 1) is required to identify a replacement hub assembly or repair components. Please provide the Marley sales representative the necessary information when ordering replacement fans or components.

Blades can be replaced without rebalancing the entire fan.

If rebalancing is desired, contact the Marley sales representative in your area.

The corrected horsepower should be close to but not exceed the contract horsepower specified. Determine corrected horsepower using the following equation.

			VOLTSA ⋅ AMPSA ⋅ DENSI-
		HPC = TYD			⋅ HPN

HPC	=	Corrected Horse-		DENSITYA	=	Actual Air Density
power	=	Actual Volts		VOLTSN	=	Nameplate Volts
VOLTSA	=	Actual Volts		AMPSN	=	Nameplate Amperage
AMPSA	=	Actual Amperage		HPN	=	Nameplate Horsepower

Actual volts and amperage must be obtained with the fan running and the specified rate of water flowing over the tower after the motor and Geareducer have reached operating temperature (approximately 30 minutes of operation).

Measurements taken on motors operating with Variable Fre-

Notequency Drive controls may read up to 15% high from errors in measuring the approximated sine wave. Instruments capable of measuring a squared off wave form accurately should be used for measuring power in this situation.

Do not exceed 30 sec/hour total motor starting time as motor may overheat.
