Routine Maintenance:
Included with the instruction packet are separate User Manuals on major op-
erating components 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. The purchaser or owner
is responsible for providing a safe method for entering or exiting
the access doors if required.
Weekly
visually inspect the fluid cooler to assess general operating condi-
tions and for signs of microbial growth and appearance of debris, scale and
corrosion. Refer to ASHRAE Standard 188 and Guideline 12 for specific
frequency recommendations. Consult a knowledgeable water treatment
professional to maintain fluid cooler hygiene.
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. The fan motor should be shut off when dampers are closed. Sea-
sonal periods where the damper assembly remains open or closed for extended
periods of 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
reason to shut down the fluid cooler until the problem can be located and cor-
rected. Observe operation of the pump, motor(s) and fan(s). Become familiar
with the normal operating temperature of the motor(s), as well as the sight
and sound of all components as a whole.
Inspect fill media, louvers, drift eliminators and basin trash screens and remove
any debris or scale which may have accumulated. Replace any damaged or
worn out components. Use of high-pressure water may damage the fluid
cooler components.
