TRANE

How it works tokeep you comfortab|e

Congratulations on the purchase of your new Trane heat pump.Your heat pump is designed to work with a matched indoor unitcreating a system that delivers years of dependable serviceand performance.

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

During the winter, the heat pump extracts the heat present in cold winter air and pumpsthe heat into your home. (Yes, there's heat in the air even in the coldest weather.) Insummertime, it functions as a conventional air conditioner, pulling the heat out of yourhome 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 heatpump is an air conditioner, it extracts excess moisture from the home, to help controlhumidity in muggy summer months.

Acquaint yourself with your new system by spending just a few minutes with thisbooklet. Learn about the operation of your system and the small amount of mainte-nance it takes to keep it operating at peak efficiency.

Proper maintenance formaximum efficiency

A heat pump is not a household appli-ance. It's a self-contained system thatrequires professional maintenanceand repair.

That's why attempts at "do-it-yourself"repairs on an in-warranty unit may voidthe remainder of your warranty.

Other than performing the simple main-tenance recommended in this manual,you should not attempt to make anyadjustments to your heat pump system.Your dealer will be able to take care ofany questions or problems you may have.

[_ditioning system.

Disconnect all electrical power to the indoor airhandler or furnace before removing access panelsto perform any maintenance. Disconnect power toboth the indoor and outdoor units. NOTE:There

may be more than one electrical disconnectswitch. Electric shock can cause personal injuryor death.

Help ensure top efficiency by cleaningor replacing the filter monthly.*

When the heat pump circulates andfilters the air in your home, dust anddirt particles build up on the filter.Excessive accumulation can block theairflow, forcing the unit to work harderto maintain desired temperatures. Andthe harder your unit works, the moreenergy it uses.

Clean or replace your filter twice amonth during seasons when the unitruns more often.

When replacing your filter(s), alwaysuse the same size and type that wasoriginally supplied. Filters are availablefrom your dealer.

Where disposable filters are used, theymust be replaced every month with thesame size as originally supplied.

How to remove your filter.*

Ask your Trane dealer where the filteris located in your system and how toservice it.

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

* Before removing the filter, see the owners manualfurnished with the indoor unit.

Efficiency can be maintained bykeeping outdoor unit clear of snow, iceand debris.

Efficient operation of your heat pumpdepends on the free flow of air over thecoil. Anything that blocks the airflow,causes the compressor to work harder tomove the warm air out of your house.

Buildup of snow and ice can restrictairflow. As soon as possible after accu-mulation, clean snow from the areaaround the heat pump.

To avoid overworking your unit, do notplant flowers or shrubbery right next to it.Also, make sure that nothing is stackedagainst the sides of the unit or drapedover it.

Call your dealer for additionalroutine maintenance

Your heat pump system should beinspected regularly by a properly trainedservice technician. The inspection(preferably twice each year, but atleast once a year) should includethe following:• Routine inspection of air filter(s).

Replacement or cleaning as required.

Condensate drains should be checked and cleaned

periodically to assure condensate can drain freelyfrom coil to drain. If condensate cannot drain freely,water damage could occur.

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

• Inspection and, if required, cleaning ofindoor and outdoor coils.

• Inspection of the indoor coil drain pan,plus the primary and secondary drainlines. If supplied, the auxiliary drain panand line should be inspected at thistime. Service should include cleaning,if required.

• A check of all electrical wiring andconnections.

• A check for secure physicalconnections of individual componentswithin 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 forinformation or assistance. The qualified installer

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

• Operational check for the heat pumpsystem to determine actual workingcondition. Necessary repair and/oradjustment should be performed atthis time.

• Your servicing dealer may offer aneconomical service or preventativemaintenance agreement that coversseasonal inspections. Ask yourdealer for further details.

Hew to operate your systemfor peak performance

Setting the temperature

Place the system switch on COOL, andthe fan switch on AUTO. Then set thetemperature by using the indicator onthe thermostat* control.

Now your system will cool your housewhenever the indoor temperature climbsabove the thermostat setting. It will shutoff when the desired room temperatureis reached.

In winter, it works the same way. Whenthe system switch is on HEAT, the systemwill operate whenever the room tem-perature falls below the temperaturesetting. Once the desired temperature isreached, the system will shut off.

Save energy with an electronicprogrammable thermostat.*

Program the thermostat for the tempera-tures that meet your comfort level. TheTrane electronic programmable thermo-stat has up to four setup or setbackperiods each day, plus weekend andvacation programs.

* Accessory, purchased separately. Carefully readthe accompanying thermostat manual for completeoperating instructions.

Let the thermostat do its job.

Your system will perform most efficientlywhen you let the thermostat control it.Turning the system on and off manuallyis usually much less efficient. So let thethermostat do its job.

We recommend keeping the temperaturesetting 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 toa minimum.

When you're going to be away fromhome for a few days, or when outdoortemperatures are moderate, don't let theair conditioner run unnecessarily. Lowerthe thermostat to 55°F in the winter. Andraise it to 85°F in summer. Then whenyou return, or when temperature condi-tions dictate, you can reset the systemand it will resume making your homecomfortable again.

Never stop the system by shutting offthe main power.

If the main power is ever disconnectedfor more than three hours, turn off thethermostat. Then wait for at least three

more hours after the power has beenrestored before turning the thermostatback on. Failure to follow this procedurecould result in damage to your system.

How to help reduce summer humidity.

In summer, your heat pump does morethan cool the air -- it helps remove theexcess moisture, that can make theinside of your home feel muggy. Whenremoving this moisture your system mustwork harder than when simply coolingthe air.

That's why kitchens, bathrooms andutility rooms should have vents and ex-haust fans. These devices help preventaccumulation of moisture throughout therest of the house so your air conditionerworks less to keep you comfortable.

Extra Energy Tips

Insulation

1. Make sure your home is properlyinsulated. This is the single mostimportant step in conservingenergy. Thermal insulation should bespecified in terms of thermalresistance (R-values). R-30 (10")is recommended for ceilings, R-11(3-1/2) for exterior walls and floorsover unheated areas. In colderclimates, consider additionalinsulation.

2. Infiltration of humid outside air isyour heating and cooling system'sworst enemy -- it could account for15 to 30% of air conditioning energyrequirements. Find the places whereair can sneak into the home andplug them with caulking, weather-stripping or plastic. Also, weather-strip and caulk around all entrancedoors and windows.

3. Cut heat transfer through yourwindows by 40 to 50% with doubleglazing (two panes of glass sepa-rated by a sealed air space) andIow-e glass.

4. Use wood- or metal-frame stormwindows even if single-glazedwindows are high quality. Theextra layer of glass and the layer

of still air will cut heat transferconsiderably.

5. Install storm doors at all entrances

to your house.

6. Keep all windows and doors closed.

7. Remember that by increasing theglass area, you increase the amountof heat added in summer and lostin winter.

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

9. Invest in a humidifier to conserve

energy in winter. The air in yourhome won't be as dry, so you staycomfortable at a lower temperaturesetting.

Heating10. 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 canadd 3% to the amount of energyneeded for heating.

12. People generate heat. So lower thethermostat a degree or two whenexpecting a large group of guests.

Cooling13. Set the thermostat as high as

comfort will permit.

14. Make sure attics are adequatelyventilated to relieve heat buildup.If necessary, improve airflow byadding or enlarging vents.

15. When building a new house orrenovating an old one, chooselight-colored roof shingles to reflectmore of the sun's heat.

16. During moderate weather, don't usethe air conditioner unnecessarily.

17. Draw blinds or drapes to block thesunlight during the hottest part ofthe day.

18. Install awnings over windowsexposed to direct sunlight.

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

longer than necessary.

20. Don't place lamps, TV sets or otherheat producing devices beneath awall-mounted thermostat. Risingheat from the equipment maycause the heat pump to over coolyour house.
