INSTALLATION INSTRUCTIONS

Fine Tuning

1. Allow the system to operate for at least 20 minutes
before checking refrigerant temperature and pressure.
2. Perform an air flow calculation to ensure the blower
is delivering the correct volume of air at the pressure
intended for the distribution system.
3. When the above are completed, verify that the
operating temperature and pressure comply with the
chart.
NOTE: "IDT" = Indoor Temperature
"ODT" = Outdoor Temperature
1. Remove refrigerant if the pressure is above the chart
value.
2. Add refrigerant if the pressure is below the chart value.
Perform an inspection of the entire installation and
finalize any items needed for completion. Review the
system operation, thermostat functions, and warranty
policy with the owner.
Leave this manual at the jobsite for future reference.

Operating Instructions
This system is designed to provide comfort cooling
at outside temperatures between 50°F (10°C) and
115°F(46°C). Operation outside of this temperature range
may cause unit failure and will void the warranty.
To Operate:
NOTE: Thermostat operation may vary by type and model
used. Please consult the operating manual provided with
the thermostat. The instructions below are generalized
for most models.
1. Move the switch on the thermostat to the Cool
position.
2. Set the desired temperature (between 63-86°F or
17-30°C) on the thermostat. If the room is warmer than
the setting, the unit will turn on and begin to blow cool
air after a few minutes. A hot, humid room or building
may take several hours of continuous operation to
reach the thermostat setting when starting for the first
time or at the beginning of the cooling season.
3. Set the Fan switch on the thermostat to Auto if you
want the fan to run only when cooling is needed, or to
On if you want continuous air circulation.
4. If the space will be unoccupied for four or more hours,
moving the setting to a higher temperature may save
energy. Do not raise the temperature setting by more
than 5 degrees. Changing the temperature over 5
degrees, or turning the unit off can actually cost more.
5. Be sure that furniture or other objects do not block
supply air registers or return air grilles.
IMPORTANT
If the system is turned off, wait at least 3 minutes before
restarting it. This gives the unit time to stabilize. Failure to
do so could cause compressor damage.
Maintenance:
1. Change or clean the air filter monthly, or more often if
conditions require it. Thoroughly dry a washable filter
before re-installing.
2. Contact the installer for factory recommended annual
maintenance.
