Electrical installation
This humidifier is intended to be wired directly to the integrated
control panel on your furnace. The electrical tap will provide
power to the humidifier whenever the circulating air blower is in
operation.
Read the instructions in the furnace installation manual carefully
before attempting installation or operation of this humidifier.
Failure to follow these instructions may result in improper
installation and therefore, void the manufacturer's warranty.
1.
Remove the cover from the junction box in the furnace jacket.
2.
Connect the humidifier input leads to the two (2) leads that
run to the furnace blower motor. This connection provides for
the automatic operation of the humidifier during the heating
season.
3.
The humidifier will only operate when the furnace blower is
in operation.
4.
It is recommended to install a humidistat (provided with
model 707U) in the system to provide optimum performance
when continuous air circulation is desired.
5.
If a humidistat is not used in the installation, install an ON/OFF
switch in its place. This provides a simple, yet effective,
method of turning the humidifier off during the summer
months when humidification is not desired.
