Preparation
It is not intended nor assumed that access to the fan deck on 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-flow models MHF706 and
MHF707 with Geareducer drive only.
• External motor access platform. Double-flow models MHF706 and
MHF707 with Geareducer drive only.
• Plenum walkway. Double-flow 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 available 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 appropri-
ate Marley submittal drawings. Supports must be level to insure proper
operation of the fluid cooler.
