Fluid Cooler Maintenance
Some maintenance procedures may require maintenance personnel to
enter the fluid cooler. Each cased face of the fluid cooler has a door for
access to the interior of the tower.
The optional fan deck ladder—models MHF706 and MHF707— is de-
signed and intended solely for personnel to gain access to the fan deck.
The fan deck ladder should not be used to enter or exit the access doors
located on the cased face of the tower unless the optional access door
platform is provided.
The purchaser or owner is responsible for providing a safe method

Included with this instruction packet are separate User Manuals on each
major operating component of the tower, and it is recommended that you
read them thoroughly. Where discrepancies may exist, the separate User
Manuals will take precedence.
The following is recommended as a minimum routine of scheduled main-
tenance:
Always shut off electrical power to the tower fan motor prior to
performing any inspections that may involve physical contact with
