1 Use this bulletin for preliminary layouts only. Obtain current
drawings from your Marley sales representative.
2 Pumping head contributed by the tower is static lift shown
on page 9. Actual pumping head will vary according to tower
circulating GPM. Total pumping head will be furnished at time
of proposal.
3 If your application requires a bypass system, recommended
location is through tower endwall into plenum area. Review
of the system by SPX Cooling Technologies engineering is
required.
4 Marley piping terminates at face of a cast iron flat face flange
which conforms to class 125 lb. ASME B 16.1 specifications.
5 Supports on tower for crossover piping are are part of the tower
design. Do not support the riser’s dead load or operating load
from the tower. Do not brace the riser’s seismic or thrust loads
against the tower.
