Boldface indicates field-supplied motor/drive required.

NOTES:

1. Motor drive ranges:

(E) Low Range: 687-873, 5.75 Bhp

(F) Mid-Low Range: 805-1007, 5,75 Bhp

(G) Mid-High Range: 941-1176, 863 Bhp

(H) High Range: 1014-1297, 11.50 Bhp

All other rpms require field-supplied motor or drive.

2. See betow for general fan performance notes.

GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES

1 Static pressure losses from accessories and options (HumidFMiZer TM,

economizer, etc.) must be added to externaI static pressure before enter-

ing Fan Performance table. Refer to Tables 31 and 32 for Accessory/

FlOP Static Pressure information

2 Extensive motor and electrical testing on these units ensures that the full

range of the motor can be utitized with confidence Using the fan motors

up to the bhp ratings shown wilt not result in nuisance tripping or prema-

ture motor faiture. Unit warranty will not be affected See Tables 29 and

30 (Evaporator-Fan Motor Specifications) on page 31 and 32 for addi-

tional information.

3. Use of a field-suppIied motor may affect wire sizing. Contact your local

Carrier representative for detaits

4. InterpoIation is permissible. Do not extrapolate
