Trane 2TWB0-UM-2 How it works to keep you comfortable, Proper maintenance for maximum efficiency

How it works to keep you comfortable

It heats in winter.

It cools in summer.

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, it functions 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.

Proper maintenance for maximum 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.

▲! CAUTION

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 air conditioning system.

▲! WARNING

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.

▲! CAUTION

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.

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.
