Initial Storage and/or Idle Period Recommendations

If the unit will sit for idle periods of time it is recommended that the following be performed in addition to all component
manufacturers recommended maintenance instructions .
• The fan, pump and motor bearings need to be turned by hand at least once a month . This can be accomplished by tagging
and locking out the unit's disconnect, grasping the fan assembly (or removing pump motor fan guard), and rotating it several
turns .
• If unit sits longer than one month insulation test motor windings semi-annually .
• If fan motor sits idle for at least 24 hours while the spray pumps are energized distributing water over the coil, motor space
heaters are suggested and (if equipped) should be energized . Alternatively, fan motors may be energized for 10 minutes,
twice daily, to drive any moisture condensation out of the motor windings .
