OPERATING YOUR ELECTRIC AmR CONDITIONER
The operation of'your system is conholled by the indoor thermo-

temperature at the level you select. Most themaostats have 3
controls: a temperature control selector, a FAN control, and a
SYSTEM or MODE control. RefEr to your thermostat owner's
manual for more infbrmation.
To better protect your investment and to eliminate unnecessa_
sela'ice calls, familiarize yourself with the %llowing g_cts:
Step l--Cooling Mode
With the SYSTEM or MODE control set to COOL, your unit will
run in cooling mode until the indoor temperature is lowered to the
level you have selected. On extlemely hot days, your system will
run for longer periods at a time and have shorter "o_t" periods than
on moderate days.
