BloWer sHeave assemBly data

adjusting the Blower drive setting

Based on the Sheave Arrangement, Tables 34.1 through 35.5

give the Sheave Assembly numbers used on units that include a

blower. The Sheave Arrangement is Digit 19 and is found on the

unit Model Identification Plate. The Sheave Assembly describes

the motor and blower sheave size and bore as well as the belt

provided.

To determine how many turns open the motor sheave should be

set for:

1. Follow the Selection Procedure found on pages 28 and 29

to determine what blower rpm is required to meet the job

specifications.

2. Locate the unit Model Identification Plate and note Digit 16

and Digit 19 of the model number. Digit 16 is the Blower

Size and Type and Digit 19 is the Sheave Arrangement.

3. Once the Blower Size and Type (Digit 16) is known, enter

the proper Sheave Arrangement table.

4. Use the Sheave Arrangement (Digit 19) to determine the

Sheave Assembly provided.

5. Use Table 36.1 and the Sheave Assembly number to

determine the required turns open to achieve the

desired blower rpm.

6. Set the motor sheave as described in Blower Adjustments.
