Extended Shutdown
Perform the following services whenever the unit is shutdown in
excess of three days:
• If the unit is mounted on vibration isolators or isolation rails (by
others), refer to the manufacturer’s guidelines before loading/
unloading weight from the unit.
• Disconnect, lock-out, and tag-out all fans and pumps.
• Close the shut-off valve in the make-up water line (supplied by
others), and drain the cold water basin and all exposed water
piping. Heat trace and insulate all exposed piping.
• Clean all the debris, such as leaves and dirt, from the interior and
exterior of the unit.
• Leave the cold water basin drain open so rain and melting snow will
drain from the unit.
• Clean the basin strainer and re-install.
• Cover the fan discharge to keep out dirt and debris.
• For belt driven units, lubricate the fan shaft bearings, motor base,
and motor base adjusting screw.
• Apply RUST VETO
®
to steel shafts.
• Inspect the protective finish on the unit. Clean and refinish as required.
• Maintain the fan motor starting device in the “OFF” position to
