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 designed and

intended solely for personnel to gain access to the fan deck. The fan deck lad-

der 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 mainte-

nance:

Always shut off electrical power to the tower fan motor prior to

performing any inspections that may involve physical contact with

themechanicalorelectricalequipmentinoronthetower.Lockout

and tag out any electrical switches to prevent others from turning

Weekly: Inspect for bacterial growth and general operation conditions. Bacte-

rial growth should be reported to your water treatment expert for immediate

attention.

If equipped, the damper actuator and assembly should be cycled open and

closed several times. Observe the cycle to assure that the blades and link-

age move freely. Seasonal periods where the damper assembly remains open

or closed for months at a time can allow pivot points to scale up, causing

premature failure.
