Proper Maintenance – Air Handlers

Don’t waste money heating and cooling

To prevent injury or 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.

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.

Disconnect all electric 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.

A clean ﬁlter saves money.

Help ensure top efﬁciency by cleaning the ﬁlter regularly.

When the unit circulates and ﬁlters the air in your home, dust and dirt particles collect on the ﬁlter located in your indoor unit. Excessive buildup forces the system to run longer to maintain your set temperature. And you end up paying for it.

Although special care has been taken to minimize sharp edges in the construction of the unit, be extremely careful when handling parts or reaching into the unit.

Clean or replace your ﬁlter at least once a month or twice a month when the system is running more.

If you have a semi-permanent ﬁlter, you can take the ﬁlter out of the frame and vacuum it. Where

Your ﬁlter may or may not be framed.

disposable ﬁlters are used, they must be replaced every month with the same size as originally supplied.

Both methods are quick and easy and guaranteed to cut the energy used by your system. When replacing your air handler ﬁlters, always use the same size and type that was originally supplied. Filters are available from your dealer.

when you don’t need to.

When you’re going to be away from home for a few days – or when outdoor temperatures are moderate – don’t let your system 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 temperatures dictate – you can reset the system and it will immediately begin making your home comfortable again. Continuous fan mode during cooling operation may not be appropriate in humid climates. If the indoor air exceeds 60% relative humidity or simply feels uncomfortably humid, it is recommended that the fan only be used in the AUTO mode.

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.

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 remove the ﬁlter from your Air Handler.

Ask your dealer where the ﬁlter is located when your system is installed. It may be behind the bottom panel of your indoor unit. Or it may be at the top, bottom, or either side. Or there may be two ﬁlters.

In any case, removing a ﬁlter is easy. Just make sure you insert the clean ﬁlter with the arrows on it pointing in the direction of the airﬂow.

Your installing dealer is your best source of filter and maintenance information.

Locate access door marked "FILTER" and lift up the open side of the levers.

Cut operating costs by keeping snow, ice and debris clear of your outdoor heat pump unit.

NOTE: Condensation may occur on the surface of the air handler when installed in an unconditioned location.

Efﬁcient operation of your outdoor unit requires the free ﬂow of air over the coils. Anything that blocks this ﬂow forces the unit to work harder to do its job. At no time should anything be

Slide dirty ﬁlter out, replace with a new ﬁlter making sure the arrows printed on it are pointing in the direction of airﬂow.

stacked against the side of the outdoor unit or draped over it. Keeping it clear of debris helps it work at peak efﬁciency, and that helps hold down operating costs.

The Problem Solver – Air Handlers

Before you call for service, check the following:

Problem Possible cause Possible Remedy

Insufﬁcient heating or cooling 1. Dirty ﬁlters

2. Air not circulating freely

3. Blocked outdoor coil

1. Clean or replace

2. Check supply registers and return grills for blockage

3. Clear away leaves or other debris

Failure to operate 1. Power off

2. Open circuit breaker or burned‑out fuses

3. Improperly adjusted thermostat

Unusual Noise Call your local servicer

1. Make sure main switch is in on position

2. Reset circuit breaker, or replace burned‑out fuses

3. Check setting, adjust thermostat

Just set the temperature you want.

Whenever your house is to be vacant, arrange to have someone inspect your house for proper temperature. This is very important in below freezing weather. If for any reason your unit should fail to operate, damage could result, such as frozen water pipes.

NOTE: Improperly sized vents can cause the formation of condensate, combustion gas leakage and spillage, and an inoperable furnace.

This unit is not a household appliance. It is a complex 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 maintenance recommended in this manual, you should not attempt to make any adjustments to your system.

NOTE: The blower motor bearings are factory lubricated and under normal operating conditions usually do not require servicing. Your local servicer can advise you if oiling is required. Your dealer should be able to take care of any questions or problems you may have.

Set temperatures by using the indicators on the thermostat* control. After that, your comfort control center (thermostat) will maintain a constant indoor temperature, regardless of changes in outdoor temperatures. Read your thermostat manual for directions on setting the temperatures.

Save energy with an electronic programmable thermostat.

With an electronic programmable thermostat* energy savings is easy. Just program the thermostat for the temperatures you are most comfortable with and it will automatically change settings up to four times a day. Special weekend and vacation schedules are also easily programmed for comfort and savings. Read your thermostat manual for programming instructions. If you want the optimum balance between comfort and the cost of running your system, we recommend keeping the temperature settings at 68°F for heating and 78°F for cooling.

Save energy by letting the thermostat do its job. Once you set the thermostat, keep subsequent adjustments to a minimum. Adjust it only when a new program is needed.

*Optional accessory

Keep your unit looking like new for years.

Clean the enamel ﬁnish of your unit with ordinary soap and water. For stubborn grease spots, use a household detergent. Lacquer thinner or other synthetic solvents may damage the ﬁnish.

The combustion air for your furnace must be fresh uncontaminated air. Paints, varnishes, laundry bleaches, detergents, many household cleaners, water softening salts, adhesives, and all such products release fumes containing compounds which could lead to early heat exchanger and vent system deterioration. Do not store these types of products near your furnace.

For horizontally vented furnaces, the vent and inlet terminals must be located at least 12 inches minimum (18 inches in Canada) above normally expected snow accumulation level.

Proper Maintenance – Gas Furnaces

Air Filters

Clean the filter once a month for optimum performance. A monthly visual inspection of the furnace is also recommended. See General Inspection on page 9, number 1.

NOTE: Filters are NOT included with all Furnaces, however; the Furnace should never be run without a ﬁlter.

A clean ﬁlter saves money.

When the furnace 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 has to work, the more energy it uses. So you pay more any time your system is running with a dirty ﬁlter.

Never operate your unit for either heating or cooling with ﬁlters removed.

Help ensure top efﬁciency by cleaning the ﬁlter once a month. Clean it twice a month during seasons when the unit runs more often.

You can clean the filter with a vacuum, OR you can wash it with

Regular Dealer Maintenance

FLAME

For regular dealer maintenance please refer to www.acca.org/industry/quality

To ensure proper operation of your furnace, the recommended dealer inspection is once a year, before the heating season. Regular maintenance must be performed by a qualiﬁed service professional.

The servicer should perform steps 1–9 once a year before the heating season.

The homeowner should perform the visual inspection in step 1 monthly when cleaning the furnace ﬁlter.

Unless it is an emergency, never stop the heating system by shutting off the main power.

If the main power to your air conditioner 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 furnace.
