8. PolarCool Preventive Maintenance Requirements
• Flush the system at least once per week and wipe
the reservoir clean to prevent damage to the unit.
Refer to Section 7.4.
• Allow the pads to dry out each day, by running
the fan without the pump running until the pads
are completely dry (about 15 minutes).
• Drain the system during extended shutdowns.
• Disinfect the whole system once per quarter.
• Routinely inspect fan belt (48” model only) for
looseness and inspect spray bar for debris in
holes.
• Turn off water hose to PolarCool whenever
PolarCool is not in use.
• Have the right amount of water running over the
pad.
• If power cord extension is necessary, ensure that
you use 12 AWG or larger wire.
• Ensure that air is not limited or restricted from
entering or exiting the unit.
• Identify and correct leaks in the system.
• Excessive dust, fumes, and harsh cleaners,
should be avoided.

necessity.
