Physical Installation
Remember to select a location that is readily accessible for periodic inspection and
cleaning of your humidifier. This unit should be located on the cold air return side of
the system for best results. However, if space does not permit, it can be mounted on
the warm air supply side of the system. Please keep in mind that the evaporative
capacity of the humidifier will be reduced if this alternate installation method is
utilized.
CAUTION
Only a trained service person should install this humidifier. Do not connect the
unit to power source until installation is complete. A thorough checkout of the
unit installation should be completed before operation. Failure to follow these
directions may void the manufacturer’s original warranty.
