*Select either 3/4″ or 11/4″ for power, depending on wire size.

NOTES:

1. Dimensions in [ ] are in millimeters.

2. Center of gravity.

3. Direction of airflow.

4.On vertical discharge units, ductwork to be attached to accessory roof curb only. For horizontal discharge units, field-supplied flanges should be attached to horizontal dis- charge openings, and all ductwork should be attached to the flanges.

5.Minimum clearance (local codes or jurisdiction may prevail):

a.Between unit, flue side and combustible surfaces, 48 inches.

b.Bottom of unit to combustible surfaces (when not using curb), 1 inch. Bottom of base rail to combustible surfaces (when not using curb) 0 inches.

c.Condenser coil, for proper airflow, 36 in. one side, 12 in. the other. The side getting the greater clearance is optional.

d.Overhead, 60 in. to assure proper condenser fan operation.

e.Between units, control box side, 42 in. per NEC (National Electrical Code).

f.Between unit and ungrounded surfaces, control box side, 36 in. per NEC.
