single-flow models—Models MHF702 thru MHF705—is needed or
necessary.
Those are only some of the safety issues that may arise in the design
process. SPX strongly recommends that you consult a safety engineer
to be sure that all safety considerations have been addressed.
Several options are available that may assist you in addressing some of these
personnel safety concerns, including:
• Louver face distribution basin access platform with ladder and handrail.
Louver face redistribution basin level access platform with ladder and
handrail.
• A handrail system around the perimeter of the fan deck with either one or
two ladders for access to the deck. Double-flow models MHF706 and
MHF707 only.
Extended fan deck that provides additonal access around one end of the
fan cylinder opposite the fan deck access ladder. Double-flow models
MHF706 and MHF707 only.
• Ladder extensions—used where the base of the tower is elevated.
• Safety cages for ladders.
• External lube lines.
• Access door platform.
Motor located outside the tower. Double-ow models MHF706 and MHF707
with Geareducer drive only.
External motor access platform. Double-ow models MHF706 and MHF707
with Geareducer drive only.
Plenum walkway. Double-ow models MHF706 and MHF707 only. Standard
on all other models.
• Mechanical equipment access platform.
Fluid Cooler Location
Space available around the fluid cooler should be as generous as possible
to promote ease of maintenance—and to permit freedom of airflow into and
through the fluid cooler. If you have questions about the adequacy of the avail-
able space and the intended configuration of the fluid cooler, please contact
your Marley sales representative for guidance.
Prepare a stable, level support foundation for the fluid cooler, utilizing weight,
wind load, and dimensional information appearing on appropriate Marley
submittal drawings. Supports must be level to insure proper operation of the
fluid cooler.
