INSTALLATION INSTRUCTIONS
TROUBLESHOOTING
Some models are factory equipped with the Comfort
Alertt Diagnostics device in the control box (refer to Fig-
ure 13). Comfort Alert provides around−the−clock moni-
toring for common electrical problems, compressor
defects, and broad system faults. If trouble is detected, an
alert code is displayed with a flashing LED indicator. Alert
codes are listed in Figure 14.
The device is factory wired and requires no modifica-
tion. Low voltage lead wires are provided in the control
box for connection to thermostat wires (use wire nuts).
NOTE: The RED (R) low voltage lead wire is provided
only for powering the Comfort Alert device. To utilize the
Comfort Alert device, connect the RED (R) low voltage
lead wire directly to 24 VAC hot at the indoor unit or ther-
mostat. Use one of the spare wires in the thermostat
cable to bring 24 VAC hot out to the outdoor unit. If there
are no spare wires in the thermostat cable, leave the in-
sulation on the end of the RED low voltage lead wire to
avoid an electrical short. The air conditioner will
function normally without the RED (R) low voltage
lead wire connected.
The Comfort Alert device operates by monitoring the
compressor power leads and the thermostat demand sig-
nal (Y terminal). It draws constant 24 VAC power at the R
and C terminals.
MAINTENANCE
Condensate Drain
During the cooling season, check monthly for free flow of
drainage and clean if necessary.
Cleanliness
These tips will help keep the air conditioner looking better
and working more efficiently:
1. Free flow of air is essential. Keep fences, shrubs,
trash cans, and other obstructions at least 18 inch-
es from all coil inlets.
2. Keep the coil free of grass clippings, leaves,
weeds, and other debris.
NOTE: Coil may occasionally require cleaning with
a liquid solution. The coil must be cold when clean-
ing. Use an alkaline based cleaner only. Cleaning a
hot coil or using an acid based cleaner will remove
the paint from the fins and may clog the coil.
3. Never use a weather cover over the outdoor unit
unless it is a ventilated type or made of breathable
fabric that will allow moisture to evaporate rapidly.
A cover that holds moisture in the unit will cause
more rust build−up and damage than normal expo-
sure to weather.
