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 electric heating unit automatically.
Operating the Indoor Blower Continuously
The continuous indoor blower operation is typically used to
circulate the indoor air to equalize a temperature imbalance
due to solar loads, occupancy fresh air requirements, or
mechanical equipment operation. Set the thermostat fan
mode to ON (Figure 1). The indoor blower starts immediately,
and will run continually on low speed 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.
AIR CONDITIONER MAINTENANCE
WARNING:
The S6BQ air conditioner contains liquid and
gaseous refrigerant under pressure. Installation
and servicing should only be attempted by
qualified, trained personnel thoroughly familiar
with the equipment and safe responsible
refrigerant handling procedures. Failure to
comply with this warning could result in
equipment damage, personal injury, or death.
WARNING:
To prevent electrical shock, personal injury, or
death, disconnect all electrical power to the unit
before performing any maintenance or service.
The unit may have more than one electrical
supply.
CAUTION:
DO NOT touch any of the internal electrical
components while cleaning the unit.
Proper maintenance is important to achieve optimum
performance from the air conditioner. The ability to properly
perform maintenance on this equipment requires certain
mechanical skills and tools. If you do not possess these
skills, contact your dealer for maintenance. Consult your
local dealer about the availability of maintenance contracts.
Routine maintenance should include the following:
Regular Cleaning
CAUTION:
DO NOT touch any of the internal electrical
components while cleaning the unit.
• The area around the cooling unit a must be kept clear
and free of combustible materials, gasoline, and other
flammable vapors and liquids. Do not store or use flammable
items such as paint, varnish, or strippers in the vicinity of
the unit.
• Keep the outdoor unit clean. Hose off periodically and keep
unit fins clear of leaves and grass clippings.
Be careful
not to damage the aluminum fins
. Clean the outdoor coil
and fins as necessary using a mild detergent and water.
Rinse thoroughly with water.
• Keep the outdoor unit clear of obstructions. DO NOT
obstruct airflow with tall plants or shrubs. Check for and
remove any obstructions such as twigs, sticks, etc.
• Inspect the air handler condensate drain and outdoor coil
at the beginning of each cooling season. Remove any
debris.
Air Filters
WARNING:
Never operate the unit without a filter in the return
air system. Dust and lint in the return air can
build up on the internal components, resulting
in loss of efficiency, equipment damage, and
possible fire risk.
• Inspect and clean or replace air filters at the beginning
of each heating and cooling season, or more frequently
if required. A clogged filter could cause airflow related
problems and reduce the overall efficiency of your unit.
Always replace disposable filter(s) installed in your
system only with the same size dimensional filters
that are being replaced.
• Never operate the appliance without a filter installed in the
return air duct. Inspect filters frequently and replace when
necessary with filter of same dimensional size.
