NOTE

1Use this bulletin for preliminary layouts only. Do not use for construction. Obtain current drawings from your Marley sales representative. Concrete basin design and construction are by other contractors or purchaser.

2Operating weight is total wet operating weight of tower only, excluding water in concrete basin.

3Maintain at least 2'-0" of clear space at tower endwalls for construction purposes. Air inlet faces must have unobstructed air supply. If obstructions exist nearby, consult your Marley sales representative.

4Minimum basin depth is 1'-6". Basin depth may vary to suit your storage requirements.

5All anchor bolts complete with nut and washer must be furnished by others. Bolts must be 3⁄4" diameter with 11⁄2" all-thread projection.

6Other contractors or purchaser must design, locate, construct, and furnish sump(s) and overflow(s) to suit requirements. The sump(s) should be designed according to the pump manufacturer’s recommendations. Other design sources: ANSI/HI specifications 1.1-1.5 for centrifugal pumps, 2.1-2.5 for vertical pumps, and 9.8 for pump intake design.
