NOTES:

1. The approximate operating weight of the unit is:

38AH-104---	5435 lb (2465 kg)
38AH-104--C	6160 lb (2794 kg)

2.Unit must have clearances for air¯ow as follows: Top Ð Do not restrict in any way.

Ends Ð 5 ft [1524 mm] Sides Ð 6 ft [1829 mm]

3.Mounting holes may be used to mount unit to concrete pad. They are not recommended for mounting unit to spring isolators.

4.Two 35¤8 (92-mm) dia holes are recommended for parallel conductors on 208/230 v units.

5.Circled numerals in Top View refer to condenser fans by position.

6.If spring isolators are used, a perimeter support channel between the unit and the isolators is recommended.

7.See Table 1 for rigging center of gravity (Dimensions X,Y). See Table 2A and 2B for A-D corner weights.
