• Keep Filter Clean
A clogged or improperly installed air filter on your indoor unit will
increase operating costs and shorten the life of the unit. For detailed
filter cleaning information refer to indoor unit literature.
• Do Not Block Floor, Wall or Ceiling Vents
When drapes, furniture, toys or other common household items block
vents, the restricted airflow lessens the system’s efficiency and life span.
• Do Not Cover or Block Outdoor Unit
The outdoor unit needs unrestricted airflow. Do not cover it or place
items on or next to it. Do not allow grass clippings, leaves, or other
debris to accumulate on the sides or top of the unit. And, maintain a 12”
(305 mm) minimum clearance between the outdoor unit and tall grass,
vines, shrubs, etc.
• Check Condensate Drain
Your air conditioner removes humidity from your home during the
cooling season. After a few minutes of operation, water should trickle
from the condensate drain of the indoor coil. Check this occasionally to
be sure the drain system is not clogged. Drainage will be limited if you
live in a very dry environment.
• Do Not Operate Below Minimum Operating Temperatures in
Cooling Mode
Your outdoor unit is not designed to operate below the minimum
temperatures shown below. The minimum temperature depends on
which wall control is being used:
—With Evolution Connex Control: 40°F (4°C)
—With Thermostat Control: 55°F (13°C)
System protections may not allow the unit to operate below these
minimum temperatures.
• Base Pan Drainage
Periodically check for and remove debris that has settled around the base
of your outdoor unit. This will ensure proper drainage of the base pan
and eliminate standing water inside the outdoor unit.
• Level Installation
Your Bryant dealer will install the outdoor unit in a level position. If the
support base settles or shifts and the unit is no longer level, be sure to
re-level it promptly to assure proper drainage. If you notice water or ice
collecting beneath the unit, arrange for it to be drained away from the
unit.
SEA COAST COIL MAINTENANCE
Coastal locations often require additional maintenance of the outdoor
unit due to highly corrosive airborne ocean salt. Although your new
Bryant system is made of galvanized metal and is protected by top-grade
paint, take the additional precaution of periodically washing all exposed
surfaces and the outdoor coil approximately every 3 months. Consult
your installing Bryant dealer for proper cleaning intervals and
procedures for your geographic area or ask about a service contract for
regularly scheduled professional cleaning and inspections.
TROUBLESHOOTING
Before you request dealer service, check for these easily solved
problems:
• Check the indoor and outdoor disconnect switches Also check your
main electrical panel circuit breakers or fuses.
• Check for sufficient airflow. Air filter(s) should be reasonably clean
and interior vents should be open and unobstructed.
• Check Evolution Connex Control or thermostat settings. For cooling,
your desired temperature setting should be LOWER than the
displayed room temperature, and the System/Mode control should be
on Cool or Auto.
• Time delays - depending on the Bryant air conditioner you have, there
may be delays in unit operation that are built-in to protect the
equipment and your comfort. Don't be alarmed if you notice a time
delay in operation. It may be a standard protection feature of your
equipment. Check with your Bryant Dealer for more information on
time delays.
If you need to contact your Bryant dealer for troubleshooting and/or
repairs, be sure to have the model and serial numbers of your equipment
available (there are spaces on the cover for you to write this
information).
REGULAR DEALER MAINTENANCE
In addition to the routine maintenance that you perform, your home
comfort system should be inspected regularly by a properly trained
service technician. Many dealers offer this service at a reduced rate with
a service contract. Some service contracts offer additional benefits such
as parts discounts and no additional charge for ”after hours” or
emergency service.
* Monthly maintenance items and outdoor unit rinsing may be performed by the consumer. All other maintenance items and all service work must be performed by a qualified service technician. Read all waring labels.
Notes:
1. The above list may not include all maintenance items. Inspection intervals may vary depending on climate and operating hours. Consult your HVAC dealer about a service contract for seasonal inspections.
2. Do not use harsh chemicals or high pressure water on coils. More frequent rinsing is required for units near a sea coast.
