ABOUT THE AIR CONDITIONER
This	split	system	cooling	unit	has	been	designed	and	built	
to provide many years of safe and dependable comfort, 
providing it is properly installed and maintained. With 
regular maintenance, this unit will operate satisfactorily 
year after year. Abuse, improper use, and/or improper 
maintenance can shorten the life of the appliance and 
create unsafe hazards. A regular service and maintenance 
schedule should be established to ensure efficient and 
safe operation of the unit.
OPERATING INSTRUCTIONS
Thermostat	styles	vary.	Some	models	may	not	include	
the	AUTO	mode	and	others	will	have	the	AUTO	in	place	
of	 the	 HEAT	 and	 COOL.	 Others	 may	 include	 all	 three.	
Please refer to the thermostat’s User Manual for detailed 
programming instructions.
The	thermostat	should	be	mounted	about	5	feet	above	the	
floor on an inside wall and not on an outside wall or other 
location where its operation may be adversely affected by 
radiant heat from fireplaces, sunlight, or lighting fixtures, 
and convective heat from warm air registers or electrical 
appliances.
Cooling Operation
1. Set the thermostat’s system mode to COOL or AUTO
and change the fan mode to AUTO. See Figure 1.
2. Set the temperature selector to the desired
temperature	level.	The	outdoor	fan,	compressor,	and	
blower motor will all cycle on and off to maintain the 
indoor temperature at the desired cooling level.
NOTE: If the temperature level is re-adjusted, or the 
system mode is reset, the fan and compressor in the 
outdoor unit may not start immediately. A protective 
timer circuit holds the compressor and the outdoor fan 
off	for	approximately	5	minutes	following	a	previous	
operation or the interruption of the main electrical 
power.
Heating Operation
1. Set the thermostat’s system mode to HEAT or AUTO
and change the fan mode to AUTO. See Figure 1.
2. Set the temperature selector to the desired
temperature	 level.	The	 optional	 heating	 equipment	
(furnace or electric heat) will cycle on & off to maintain 
the indoor temperature at the desired heating level.
Operating the AC for Automatic Cooling & 
Heating
1. Set the thermostat system mode to AUTO and the
thermostat fan mode to AUTO. See Figure 1.
2. Set the thermostat temperature selector to the
desired	 temperature	 level.	 The	 thermostat	 will	
maintain the desired temperature level by switching 
between either the outdoor cooling unit or the indoor 
heating unit (furnace or electric heat) automatically.
Operating the Indoor Blower Continuously
The	continuous	indoor	blower	operation	is	typically	used	
to circulate the indoor air to equalize a temperature 
unbalance due to solar loads, increased occupancy loads, 
or mechanical equipment operation. Set the thermostat 
fan	 mode	 to	 ON	 (Figure	 1).	 The	 indoor	 blower	 starts	
immediately, and will run continually until the fan mode 
is	reset	to	AUTO.
NOTE:	The	continuous	indoor	blower	operation	can	be	
obtained with the thermostat system mode set in any 
position,	including	OFF.
Turning the Air conditioner Off
Change	the	thermostat’s	system	mode	to	OFF	and	the	fan	
mode	to	AUTO	(See	Figure	1).	
NOTE: The system will not
operate, regardless of the temperature selector setting.
