1. When installing the evaporative cooler, special consideration should be given to the physical positioning of
the unit, electrical power supply, the proper water supply, and the structural members to support the
cooler at the operating weights. It is recommended that supports be placed within every four feet to
distribute the weight evenly. Be sure the supports are level.
2. After the unit is properly located, electrical connection may be made. If the Evaporative Cooler has been
purchased separately, wiring from a 115 volt supply may be connected to the junction box supplied with
the unit. Refer to the wiring schematic supplied in owner's packet or, pages 4 and 5 of typical wiring
schematics, and to drawings for standard unit, units with automatic drain kit, or units with automatic drain
kit and freeze protection.
When the evaporator cooler is purchased with a system exhaust blower and filter, most connections
may have been made already. Refer to schematic with owner's packets for any additional wiring to be
done.
