NOTES:

1. Dimensions in [ ] are in millimeters.

2.Center of Gravity includes economizer. Unit weight does not include economizer.

3.Unit clearances:

Top Ð Do not restrict condenser fans Control Box End Ð 6 -0

Sides Ð 6 -0

Economizer End Ð 6 -0 (except power exhaust units 10 -0 )

For smaller service and operational clearances, con- tact Carrier Product Engineering Department.

4.Vertical discharge ducts designed to be attached to accessory roof curb. If unit is mounted on dunnage, support the ducts using cross braces as done on the accessory roof curb.

5.When unit is slab mounted, locate the condensate drain as low as possible on vertical face of base rail at the same location as the standard condensate drain (using factory supplied ®tting). Plug factory drilled con- densate hole.
