TRANE

How it works to
keep you comfortab|e

Congratulations on the purchase of your new Trane heat pump.
Your heat pump is designed to work with a matched indoor unit

creating a system that delivers years of dependable service
and performance.

The heat pump is an air conditioning system that both heats and cools. It uses electric
energy to move the heat that already exists.

During the winter, the heat pump extracts the heat present in cold winter air and pumps
the heat into your home. (Yes, there's heat in the air even in the coldest weather.) In
summertime, itfunctions as a conventional air conditioner, pulling the heat out of your

home and releasing it outside.
Your heat pump also filters and dehumidifies.
When the Weathertron ®heat pump circulates air, it also filters it. And since the heat

pump is an air conditioner, it extracts excess moisture from the home, to help control

humidity in muggy summer months.
Acquaint yourself with your new system by spending just a few minutes with this

booklet. Learn about the operation of your system and the small amount of mainte-

nance it takes to keep it operating at peak efficiency.

A heat pump is not a household appli-
ance. It's a self-contained system that
requires professional maintenance
and repair.

That's why attempts at "do-it-yourself"

repairs on an in-warranty unit may void

the remainder of your warranty.

Other than performing the simple main-
tenance recommended in this manual,
you should not attempt to make any

adjustments to your heat pump system.

Your dealer will be able to take care of

any questions or problems you may have.

[_ditioning system.

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.

Proper maintenance for
maximum efficiency

Help ensure top efficiency by cleaning

or replacing the filter monthly.*
When the heat pump circulates and

filters the air in your home, dust and
dirt particles build up on the filter.

Excessive accumulation can block the

airflow, forcing the unit to work harder
to maintain desired temperatures. And
the harder your unit works, the more
energy it uses.

Clean or replace your filter twice a

month during seasons when the unit
runs more often.

When replacing your filter(s), always

use the same size and type that was
originally supplied. Filters are available
from your dealer.

Where disposable filters are used, they

must be replaced every month with the
same size as originally supplied.

How to remove your filter.*
Ask your Trane dealer where the filter

is located in your system and how to
service it.

Just be sure to replace it with the arrows
pointing in the direction of the airflow.

* Before removing the filter, see the owners manual

furnished with the indoor unit.

Efficiency can be maintained by
keeping outdoor unit clear of snow, ice

and debris.
Efficient operation of your heat pump

depends on the free flow of air over the
coil. Anything that blocks the airflow,
causes the compressor to work harder to
move the warm air out of your house.

Buildup of snow and ice can restrict
airflow. As soon as possible after accu-

mulation, clean snow from the area
around the heat pump.

To avoid overworking your unit, do not

plant flowers or shrubbery right next to it.
Also, make sure that nothing is stacked
against the sides of the unit or draped

over it.

Proper maintenance (cont.)

Making sure your outdoor unit is kept
clear at all times helps itwork at peak
efficiency.

Keep your heat pump looking

new for years.
Clean the enamel finish of your heat

pump 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.
Call your dealer for additional

routine maintenance
Your heat pump system should be

inspected regularly by a properly trained
service technician. The inspection
(preferably twice each year, but at
least once a year) should include
the following:

• Routine inspection of air filter(s).
Replacement or cleaning as required.

V!_ [_:_ii i [e]_I

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.

• Inspection and cleaning of the blower
wheel, housing, and motor as required.

• Inspection and, if required, cleaning of

indoor and outdoor coils.

• Inspection of the indoor coil drain pan,

plus the primary and secondary drain
lines. If supplied, the auxiliary drain pan
and line should be inspected at this

time. Service should include cleaning,

if required.

• A check of all electrical wiring and
connections.

• A check for secure physical
connections of individual components

within units.

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. The qualified installer

or agency must use factory-authorized kits or
accessories when modifying this product.

• Operational check for the heat pump
system to determine actual working

condition. Necessary repair and/or
adjustment should be performed at

this time.

• Your servicing dealer may offer an
economical service or preventative
maintenance agreement that covers
seasonal inspections. Ask your

dealer for further details.

Hew to operate your system

for peak performance

Setting the temperature
Place the system switch on COOL, and

the fan switch on AUTO. Then set the
temperature by using the indicator on

the thermostat* control.
Now your system will cool your house

whenever the indoor temperature climbs
above the thermostat setting. It will shut
off when the desired room temperature

is reached.
In winter, it works the same way. When

the system switch is on HEAT, the system
will operate whenever the room tem-
perature falls below the temperature
setting. Once the desired temperature is
reached, the system will shut off.

Save energy with an electronic
programmable thermostat.*

Program the thermostat for the tempera-
tures that meet your comfort level. The
Trane electronic programmable thermo-
stat has up to four setup or setback
periods each day, plus weekend and
vacation programs.

* Accessory, purchased separately. Carefully read

the accompanying thermostat manual for complete
operating instructions.

Let the thermostat do its job.
Your system will perform most efficiently

when you let the thermostat control it.

Turning the system on and off manually

is usually much less efficient. So let the

thermostat do its job.

We recommend keeping the temperature
setting at 78°F for cooling, 68°F for heat-
ing. However, you can select the tem-
perature that meets your comfort level.

The point is, once you've set the thermo-

stat, keep subsequent adjustments to
a minimum.

When you're going to be away from
home for a few days, or when outdoor

temperatures are moderate, don't let the

air conditioner run unnecessarily. Lower

the thermostat to 55°F in the winter. And

raise it to 85°F in summer. Then when

you return, or when temperature condi-
tions dictate, you can reset the system

and it will resume making your home
comfortable again.

Never stop the system by shutting off

the main power.

If the main power is ever disconnected

for more than three hours, turn off the
thermostat. Then wait for at least three

more hours after the power has been
restored before turning the thermostat
back on. Failure to follow this procedure

could result in damage to your system.

How to help reduce summer humidity.
In summer, your heat pump does more

than cool the air -- it helps remove the
excess moisture, that can make the

inside of your home feel muggy. When
removing this moisture your system must

work harder than when simply cooling
the air.

That's why kitchens, bathrooms and
utility rooms should have vents and ex-

haust fans. These devices help prevent
accumulation of moisture throughout the

rest of the house so your air conditioner
works less to keep you comfortable.

Extra Energy Tips

Insulation

1. Make sure your home is properly
insulated. This is the single most
important step in conserving
energy. Thermal insulation should be
specified in terms of thermal
resistance (R-values). R-30 (10")
is recommended for ceilings, R-11
(3-1/2) for exterior walls and floors

over unheated areas. In colder
climates, consider additional

insulation.

2. Infiltration of humid outside air is
your heating and cooling system's

worst enemy -- it could account for
15 to 30% of air conditioning energy
requirements. Find the places where

air can sneak into the home and
plug them with caulking, weather-

stripping or plastic. Also, weather-
strip and caulk around all entrance

doors and windows.

3. Cut heat transfer through your

windows by 40 to 50% with double
glazing (two panes of glass sepa-
rated by a sealed air space) and
Iow-e glass.

4. Use wood- or metal-frame storm

windows even if single-glazed
windows are high quality. The
extra layer of glass and the layer

of still air will cut heat transfer
considerably.

5. Install storm doors at all entrances
to your house.

6. Keep all windows and doors closed.

7.

Remember that by increasing the
glass area, you increase the amount
of heat added in summer and lost

in winter.

8. Make sure fireplaces have tight-
fitting dampers which can be closed
when the fireplace is not in use.

9. Invest in a humidifier to conserve
energy inwinter. The air in your

home won't be as dry, so you stay
comfortable at a lower temperature
setting.

Heating

10. Locate the thermostat on an inside
wall away from windows and doors.

11. Set the thermostat as low as comfort
permits. Each degree over 68°F can

add 3% to the amount of energy

needed for heating.

12. People generate heat. So lower the
thermostat a degree or two when
expecting a large group of guests.

Reduce the burden of unexpected repair bills
with a Trane Extended Warranty.

Trane offers the finest quality products and manufacturer's

warranties on the market. But, like all good things, the Trane-
provided limited warranty on your new comfort equipment

will come to an end. To keep you protected, Trane offers the
Extended Warranty Program. It picks up right where your

Trane limited warranty leaves off. And, it offers years and
years of reliable protection at a low cost. Ask your dealer

for program details.
The Trane Extended Warranty provides:

1. The opportunity to supplement your Limited Warranty
for five or ten years.

2. Coverage that may include parts only or parts and labor
for the duration of the agreement. Be certain you read the

Extended Warranty for complete details and exclusions.

3. Service work performed by servicers knowledgeable of
the operation of Trane equipment.

Cooling

13. Set the thermostat as high as
comfort will permit.

14. Make sure attics are adequately

ventilated to relieve heat buildup.

If necessary, improve airflow by
adding or enlarging vents.

15. When building a new house or
renovating an old one, choose
light-colored roof shingles to reflect

more of the sun's heat.

16. During moderate weather, don't use

the air conditioner unnecessarily.

17. Draw blinds or drapes to block the
sunlight during the hottest part of

the day.

18. Install awnings over windows
exposed to direct sunlight.

19. In the cooling season, don't run
kitchen and bath exhaust fans

longer than necessary.

20. Don't place lamps, TV sets or other
heat producing devices beneath a
wall-mounted thermostat. Rising
heat from the equipment may
cause the heat pump to over cool

your house.
