Preparation

The Marley AV Series cooling tower purchased for this installation repre- sents the current state of the art in crossflow, induced draft cooling tower design. Thermally and operationally, it is the most efficient cooling tower of its class.

These instructions—as well as those offered separately on motors, fans, float valves, etc.—are intended to assure that the tower serves you prop- erly for the maximum possible time. Since product warrantability 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 find the answers in this manual, please contact your Marley sales representative. When writing for information, or when order- ing parts, please mention tower serial number shown on the nameplate located on the access door.

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 Technologies 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.

Warning

The following safety issues should be considered by those responsible for designing the tower installation.

access to and from maintenance access doors

the possible need for ladders (either portable or permanent) to gain access to the distribution basin or maintenance access doors

the possible need for distribution basin 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.

It is not intended nor assumed that access to the fan deck is needed or necessary.
