How your system works

Cooling cycle
If your hand is wet and you blow on it, it feels cool because some of the moisture is evaporating and becoming a vapor. This process requires heat. The heat is being taken from your hand, so your hand feels cool. That is what happens with an air conditioner. During the cooling cycle, your system removes heat and humidity from your home and transfers this heat to the outdoor air.

Heating cycle (heat pumps)
During the heating cycle, your system removes heat and humidity from the outdoor air and transfers this heat to your home. This is possible because even 0°F outdoor air contains a great deal of heat. Your heat pump does not generate much heat, it just transfers it from one place to another.

System operation
Your thermostat puts full control of the comfort level in your home at your fingertips. Do not switch your thermostat rapidly ON and OFF or between HEAT to COOL. This could damage your equipment. Always allow at least 5 min between changes.

Setting the thermostat

CAUTION
The main power to the system must be kept ON at all times to prevent damage to the outdoor unit compressor. If necessary, the thermostat control switch should be used to turn the system OFF. Should the main power be disconnected or interrupted for 8 hours or longer, do not attempt to start the system for 8 hours after the power has been restored to the outdoor unit. If heat is needed during this 8 h period, use emergency heat.

Thermostats

Although thermostats may vary widely in appearance, they are all designed to perform the same basic function: to control the operation of your air conditioning or heat pump system. Regardless of size or shape, each thermostat features a temperature indicator; a dial, arm, or pushbutton for selection of the required temperature; a fan switch to choose the indoor fan operation; and a comfort switch to select the system mode of operation. Only approved thermostats have been tested and are fully compatible with this equipment. Be aware that many different thermostats operate on batteries or power-stealing principles. These types of thermostats cannot be supported as trouble-free when used with this product. If your system is designed to allow both cooling and heating operation, you may have either a manual change-over type or a programmable electronic type thermostat. Manual change-over simply means that the comfort switch must be manually positioned every time you wish to switch from the cooling to heating or heating to cooling modes of operation. The manufacturer of each thermostat provides complete operating instructions. Familiarize yourself with its correct operation to obtain maximum comfort with minimum energy consumption. The computerized electronic thermostat is a sophisticated electronic version of a manual change-over type. This thermostat includes features that allow set-back temperature variations for periods of sleep or while you are away during the day, and means energy savings. The thermostat also features a digital clock.

Cooling only
If your air conditioning system provides cooling only (AC), with no capability for heating operation (heat pump), a two-stage cooling-only thermostat, with a manual, one-position Cool and Off comfort switch is all that is required for system operation.

Cooling and heating (heat pump)
If your system allows both cooling and heating operation, you may have either a manual change-over type or a programmable electronic type thermostat with two stages of cooling and two stages of heat.

Manual change-over
Manual change-over means that the comfort switch must be manually positioned every time you wish to switch from the cooling to heating or heating to cooling modes of operation.

Programmable electronic thermostats
The computerized electronic thermostat is a sophisticated electronic version of a manual change-over type. This thermostat includes features that allow set-back temperature variations for periods of sleep, or while you are away during the day, and means energy savings. The thermostat also features a digital clock.

Fan operation selection
A multi-position fan switch allows you to choose the type of fan operation of the indoor fan.

AUTO
With the thermostat fan switch set to AUTO, the fan will run intermittently as required for either heating or cooling. This position will provide the lowest operating cost. If you purchased one of our thermostats, they have an Intelligent fan mode that continually circulates the air during occupied modes or when you are at home and can cycle the fan during unoccupied mode or the night while you sleep to further conserve energy.

ON

Continuous fan operation: With the thermostat fan switch set to ON, the indoor fan will not shut off. However, the cooling (AC) or heating (heat pump) systems will still operate as required by room temperatures. This provides continuous air filtering and more even temperature distribution to all conditioned spaces.

Fan-only operation: On moderate days, usually during spring and fall, when neither heating nor cooling is required, you may want to run only the fan to ventilate, circulate, and filter the air in your home or building. Set the comfort control switch to OFF and the fan switch
to ON. Be sure to return the switches to their original positions for normal operation.

Start-up

The maximum and minimum conditions for operation must be observed to ensure a system that will give maximum performance with minimum service.

The comfort control switch is assumed to be in the OFF position. If the main power supply to the outdoor and indoor units is off, turn the appropriate disconnects to the ON position. Place the system into operation by completing the following steps:

1. Set the temperature adjustment to the desired temperature on your thermostat.
   Cooling – The higher the setting, the lower the amount of energy consumed. Federal Guidelines recommend a setting of 78°F.
   Heating – The lower the setting, the lower the amount of energy consumed. Federal guidelines recommend a setting of 65°F or lower.
   NOTICE
   If your cooling and heating temperature adjustments are separate, be sure to set both.

2. After considering the Fan operation selection section, select and set the fan operation mode you desire.

3. Move the comfort control switch to the desired mode of operation (cooling or heating) found on your particular thermostat.

Power failure
When accidents, wind storms, or other occurrences disrupt the electrical power supply to your house, switch the thermostat to the OFF position.

System operation

Manual change-over thermostat

Cooling your home: With the comfort control switch in the COOL position, the system operates as follows: When the indoor temperature rises above the level indicated by the temperature adjustment setting, the system starts. The outdoor unit operates and the indoor fan circulates the cooled, filtered air. When the room temperature falls to the selected setting, the system shuts off.

Heating your home: If your system includes a heating unit and the comfort control switch is in the HEAT position, the system operates as follows: When the indoor temperature drops below the level indicated by the temperature adjustment setting, the system starts. The heating system operates and the indoor fan circulates the filtered air. When the room temperature rises to the selected setting, thesystem shuts off. Whether heating or cooling, the fan continues to operate if the fan switch is set in the ON or Intelligent position. The AUTO setting on the fan switch allows the fan to shut off when your system does.

Electronic thermostat
The computerized electronic thermostat, when programmed, functions automatically to operate the system as follows: When the indoor temperature rises above the higher (COOL) setting, the outdoor unit operates and the indoor fan circulates the cooled filtered air. When the room temperature falls to the selected level, the system shuts off. The indoor fan either shuts off or runs continuously, depending on your choice of fan switch setting. When the indoor temperature drops below the lower (HEAT) setting, the heating system operates and the indoor fan circulates the heated, filtered air. When the indoor temperature rises to the selected setting, the system shuts off. The indoor fan either shuts off or runs continuously, depending on your choice of fan switch setting.

Maximizing operating efficiency

Heating conservation
For the most efficient operation, keep storm windows and doors closed all year long. They not only help insulate against heat and cold, but they also keep out dirt, pollen, and noise. Closing drapes at night, keeping fireplace dampers closed when not in use, and running exhaust fans only when necessary help you retain the air you have already paid to heat. Keep lamps, televisions, or other heat-producing sources away from the thermostat. The thermostat senses this extra heat and is not able to maintain the inside temperature to the desired comfort level.

Cooling conservation
To comfortably cool your home, your air conditioner must remove both heat and humidity. Do not turn your system off even if you are away all day. On a hot day, your system may have to operate between 8 h to 12 h to reduce the temperature in your home to a normal comfort level.
Keep windows closed after sundown. While the outdoor temperature at night may be lower than indoors, the air is generally loaded with moisture which is soaked up by furniture, carpets, and fabrics. This moisture must be removed when you restart your system. The hotter the outside temperature, the greater the load on your system. Therefore, do not be alarmed when your system continues to run after the sun has set on a hot day. Heat is stored in your outside walls during the day and continues to flow into your home for several hours after sunset. Use your kitchen exhaust fan when cooking. One surface burner on HIGH requires 1 ton of cooling. Turn on your bathroom exhaust fan while showering to remove humidity. However, do not run the exhaust fan excessively as this decreases efficiency by removing conditioned air. You can also help your system in the summer by closing drapes or blinds and by lowering awnings on windows that get direct sunlight.

Care of system
It is essential to perform regular periodic preventative maintenance on this equipment. The person most familiar with the equipment in your HVAC system is a dealer.
The dealer can ensure your maintenance program meets the conditions of the warranty, maximize the efficiency of the equipment, and service your unit within the federally mandated guidelines about unlawful discharge of refrigerants into the atmosphere.

Coil care
Keep the outdoor unit free of foliage, grass clippings, leaves, paper, and any other material that could restrict the correct airflow in and out of the unit. Vacuum the coil to remove any debris from between the fins. If the coil becomes excessively dirty, turn the main disconnect switch to OFF and wash the coil with your garden hose. Avoid getting water into the fan motor and control box. Flush dirt from the base pan after cleaning the coil.

Service calls
To avoid unnecessary service calls if the unit stops functioning correctly, check the following items before calling your servicing dealer:

• Indoor section for a dirty filter.
• Outdoor section for a leaf or debris blockage. Eliminate the problem, turn off the thermostat for 10 s, and attempt to start. Wait 5 min. If the system does not start, call your servicing dealer.

WARNING
Your system contains environmentally friendly refrigerant R-410A, which operates at high pressures. You may be in danger if you try to attempt to repair your unit. Please contact your local dealer.

Filter care
Inspect the air filters at least once a month. If they are dirty, wash reusable filters with a mild detergent per the manufacturer’s recommendations. Replace disposable filters with new filters. Install the clean filters with the airflow arrow in the same direction as the airflow in your duct. Filters must be clean to ensure maximum efficiency and adequate air circulation.

Clearances
The minimum clearances shown below must be maintained if doing any patio or yard improvements around the outdoor unit.

Parts information
Replacement parts are available from your local contractor/dealer.

Extended warranty
Special warranty packages (called YORK Care Performance Promise) are available through your contractor. These packages reduce the potential cost of service calls following the first year of operation on your cooling (or heating/cooling) system.

Some efficiency dos and do not

• Do not heat or cool unused household areas. Reduce supply and return airflow to a minimum in areas that are not living spaces (storage rooms, garages, basements).
• Do not keep adjusting your thermostat. Moving your thermostat setting does not make your system heat or cool any faster. Adjust your thermostat to a comfortable setting and leave it there.
• Do not restrict air circulation. Placing furniture, rugs, and other items in such a way that they interfere with air vents makes your system work harder to achieve a comfortable temperature level. This requires more energy, which means a greater cost to you.
• Do not locate lamps or other heat-producing appliances (radios, TVs, heaters) near your thermostat. The heat from these items gives your thermostat false information about the temperature in the room.
• Do select a comfortable thermostat setting, but keep in mind that moderation in temperature selection saves energy.
• Do turn on your kitchen exhaust fan when cooking and your bathroom exhaust fan when showering. Also, make sure your clothes dryer is adequately vented. If you neglect these items, this may create excess heat and humidity conditions, causing your air conditioning system to run longer.
• Do set your thermostat a few degrees lower than normal for several hours before entertaining a large group of people in a relatively small area. People give off a considerable amount of heat and moisture in a closed area.
• Do keep drapes and Venetian blinds closed when practical. These items provide insulation against heat loss/gain.
• Do contact a qualified service person to make repairs or adjustments to your system. They have been trained to perform this service.

Characteristics of heat pumps

A constant heat
Heat pumps have a noticeably cooler supply air temperature than furnaces. The common practice of over-sizing furnaces contributes to an off-and-on again operation with short blasts of hot supply air. The heat pump system is sized more closely to the heating needs of your home. Heat is supplied at a lower temperature over a longer period to provide a more constant heat, and it may give you the impression that your system never stops running.

Water run-off
During the heating cycle in mild weather, you may notice water running off the outdoor coil. Moisture from the air is condensed on the outside surface of the coil where it gathers and runs off. This is normal and does not require attention.

Outdoor coil defrosting
At certain outdoor conditions (low temperature, high humidity), frost may build up on the coil of the outdoor unit. To maintain heating efficiency, the system automatically defrosts itself. Steam rising from the outdoor unit is normal and is an indication of correct operation. The vapor cloud only lasts for a few minutes. When the defrost cycle completes, the system automatically switches back to heating. Auxiliary heat is automatically energized to maintain comfort during defrosting.
