1 Use this bulletin for preliminary layouts only. All
dimensions show anchor bolt locations. Obtain current
drawings from your Marley sales representative before
designing supports.
2 Other contractors or purchaser must design and erect
supporting steel.
3 If steel beams are used, they must include
7
⁄8" dia. holes to
accept anchor bolts provided. If concrete beams or pilasters
are used,
3
⁄4" dia. anchor bolts embedded in the concrete must
be provided by others.
4 Maintain no less than 2'-0" of clear space at endwall faces for
construction purposes. Air inlet faces must have unobstructed
air supply. Consult your Marley sales representative if nearby
obstructions may interfere.
5 Operating weight is wet weight of tower and wood basin,
including 6" of water in the collection basin. This is the
recommended operating water level for all models.
