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/motor/pump bearings 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 the pump motor fan guard), and rotating it
several turns.
• If unit sits longer than a few weeks, run gear reducer (if equipped) for 5 minutes weekly.
• If unit sits longer than 3 weeks, completely fill gear reducer with oil. Drain to normal level prior to running.
• 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
(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.
• If coil sits longer than one month, nitrogen charge the coil.
• Energize fan motors space heaters.
