Routine 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 fluid cooler.
The optional fan deck ladder—models MHF7111 and MHF7113—is designed
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 fluid cooler unless the optional access door platform
is provided.
The purchaser or owner is responsible for providing a safe method
for entering or exiting the access door. Use of the fan deck ladder
to enter or exit the access doors may result in a fall.
Included with this instruction packet are separate User Manuals on each
major operating component of the fluid cooler, 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 maintenance:
Always shut off electrical power to the fluid cooler fan motor prior
to performing any inspections that may involve physical contact
with the mechanical or electrical equipment in or on the fluid cooler.
Lock out and tag out any electrical switches to prevent others from
turning the power back on. Service personnel must wear proper
personal protective clothing and equipment.
Weekly:
Inspect for bacterial growth and general operation conditions.
Bacterial growth should be reported to your water treatment expert for im-
mediate 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 linkage
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.
Monthly (Weekly at start up):
Observe, touch, and listen to the fluid cooler.
Become accustomed to its normal appearance, sound, and level of vibration.
Abnormal aspects relating to the rotating equipment should be considered
