Movement of air must not be obstructed by furniture, door,
draperies, etc. The thermostat must not be mounted where it
will be affected by drafts, hot or cold water pipes or air ducts in
walls, radiant heat from fireplace, lamps, the sun, television,
etc. Consult the Instruction Sheet packaged with thermostat
for mounting instructions.
All units have one stage of heating and one stage of
mechanical cooling. Units which will have economizers may
use thermostats with one or two stages of cooling.
The units are designed for operation on 60 hertz current and
at voltages as shown on the rating plate. All internal wiring in
the unit is complete. It is necessary to bring in the power supply
to the contactor as shown on the unit wiring diagram which is
supplied with each unit. 24 volt wiring must be connected
between the unit control panel and the room thermostat.
