Trane 4TTB4 Owner's Information

Congratulations on the purchase of your new outdoor unit. Your outdoor unit is designed to
work with a matched indoor unit creating a system that delivers years of dependable service
and performance.
Proper Maintenance*
Your system requires maintenance and repair by a properly trained service technician. "Do‑it‑yourself"
repairs on an in‑warranty unit may void your warranty.
Other than performing the simple main tenance recommended below, you should not attempt to make
any adjustments or repairs to your system. Your dealer can assist you with questions or problems.
1) Replace the air filter(s)
A clean filter saves you money by helping ensure top system efficiency.
When replacing your filter(s), always use the same size and type that was originally supplied or consult
with your dealer for recommendations. Be sure to replace it with the arrows pointing in the direction of
the airflow.
Where disposable filters are used, they must be replaced every month with the same size as originally
supplied. Clean or replace your filter twice a month during seasons when the unit runs more often.
Ask your dealer where the filter is located in your system and how to service it.
2) Maintain free outdoor coil airflow
Efficient operation of your system depends on the free flow of air over outdoor unit's coil.
Do not plant flowers or shrubbery right next to the unit. Also, make sure that nothing is stacked against
the sides of the unit or draped over it.
Buildup of snow and ice can restrict airflow. As soon as possible after accumulation, clean snow from the
area around the outdoor unit.
3) Clean the finish
To keep your system looking new for years, clean the enamel finish with soap and water. For stubborn
grease spots, use a household detergent. Do not use lacquer thinner or other synthetic solvents as they
may damage the finish.
4) Call your dealer for additional routine maintenance
Your system should be inspected at least once per year by a properly trained service technician.
Ask your dealer about economical service or preventative maintenance agreements that cover seasonal
inspections. Optional extended warranties are also available.
WARNINGS
!
1.
Disconnect all electrical power to the indoor air handler or
furnace before removing access panels to perform any
maintenance. Disconnect power to both the indoor and outdoor
units. NOTE: There may be more than one electrical disconnect
switch. Electric shock can cause personal injury or death.
2. Improper installation, adjustment, alteration, service,
maintenance, or use can cause explosion, fire, electrical
shock, or other conditions which may cause personal
injury or property damage. Consult a qualified installer or
service agency for information or assistance.
IMPORTANT: If the indoor air exceeds 60% relative humidity or simply feels uncomfortably
humid, it is recommended that the indoor fan only be used in the AUTO mode.
CAUTIONS
!
1. To prevent injury, death, or property damage, read and follow all instructions and warnings,
including labels shipped with or attached to unit before operating your new outdoor system.
2. Although special care has been taken to minimize sharp edges in the construction of your
unit, be extremely careful when handling parts or reaching into the unit.
3.
Condensate drains should be checked and cleaned periodically to assure condensate can
drain freely from coil to drain. If condensate cannot drain freely, water damage could occur.
4. If heating system is not operational during the cold weather months, provisions must be
taken to prevent freeze-up of all water pipes and water receptacles. This is very important
during times of vacancy.
