Preparation
The Marley MD cooling tower purchased for this installation represents
the current state of the art in counterow, induced draft cooling tower
design. Thermally and operationally, it is the most efcient cooling tower
of its class.
These instructions—as well as those offered separately on motors, fans,
controls, vibration switches, etc.—are intended to assure that the tower
serves you properly for the maximum possible time. Since product warrant-
ability may well depend upon your actions, please read these instructions
thoroughly prior to operation.
If you have questions about the operation and/or maintenance of this tower,
and you don’t nd the answers in this manual, please contact your Marley
sales representative. When writing for information, or when ordering parts,
please include the serial number shown on the tower nameplate.
Safety First
The location and orientation of the cooling tower can affect the safety of
those responsible for installing, operating or maintaining the tower. How-
ever, since SPX Cooling does not determine the location or orientation of
the tower, we cannot be responsible for addressing those safety issues
that are affected by the tower’s location or orientation.
The following safety issues should be considered by those responsible
for designing the tower installation.
• access to and from the collection basin
• access to and from mechanical access door
• the possible need for ladders (either portable or permanent) to
gain access to the mechanical access doors
• the possible need for external mechanical access platforms
• potential access problems due to obstructions surrounding the tower
• lockout of mechanical equipment
• the possible need for safety cages around ladders
• the need to avoid exposing maintenance personnel to the poten-
tially unsafe environment inside the tower.
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.
