NOTES:

1.

Place unit on curb as close as possible to the duct end.

2.

Dimension in ( ) is in millimeters.

3.Hook rigging shackles through holes in base rail as shown in detail “A.” Holes in base rails are centered around the unit center of gravity. Use wooden top skid when rigging to prevent rigging straps from damaging unit.

4.Weights include base unit without economizer. See Table 1 for unit operating weights with accessory economizer.

5.Weights include base unit without the Perfect Humidityt adaptive dehumidification system. See Table 1 for unit operating weights with the Perfect Humidityt system.

Fig. 7 ---Roof Curb Alignment

Support gas piping as shown in the table in Fig. 11. For example, a 3/4-in. gas pipe must have one field-fabricated support beam every 8 ft. Therefore, an 18-ft long gas pipe would have a minimum of 3 support beams, and a 48-ft long pipe would have a minimum of 6 support beams.

!WARNING

PROPERTY DAMAGE HAZARD

Failure to follow this warning could result in personal injury, death and property damage.

All panels must be in place when rigging and lifting.

See Fig. 11 for typical pipe guide and locations of external manual gas shutoff valve.

NOTE: If accessory thru-the-bottom connections and roof curb are used, refer to the Thru-the-Bottom Accessory Installation Instructions for information on power wiring and gas connection piping. The power wiring, control wiring and gas piping can be routed through field-drilled holes in the basepan. The basepan is specially designed and dimpled for drilling the access connection holes.

!WARNING

FIRE, EXPLOSION HAZARD

Failure to follow this warning could result in personal injury, death and/or property damage.

When connecting the gas line to the unit gas valve, the installer MUST use a backup wrench to prevent damage to the valve.
