Any time you see this symbol in manuals, instructions and on the unit, be aware of the potential for personal injury. There are three levels of precaution:

DANGER identifies the most serious hazards which will result in severe personal injury or death.

WARNING signifies hazards that could result in personal injury or death.

CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.


Our products are designed, tested and built in accordance with US Department of Energy standardized procedures and other standards; however, actual operating results and efficiencies may vary based on manufacturing and supplier tolerances, equipment configuration, operating conditions and installation practices.

Identifying Your System Your new air conditioning system is called a ”split system.” It has an outdoor unit and an indoor unit connected to each other with copper tubing called refrigerant lines. Each of these units has a rating plate with the model and serial numbers you will need to reference when calling an authorized dealer about your system. Take a few moments now to locate those numbers and record them for future reference.

Using Your New System Your air conditioning system is controlled by a wall-mounted thermostat installed inside your home. Because there are so many thermostats available, please refer to the owner’s manual supplied with your thermostat for complete details on system operation.

2-Stage Operation If you own a two-stage air conditioning system, you may notice your system runs for longer periods of time. When appropriately sized, nearly 80% of the time it’s running, it is operating in low-stage, and your indoor temperature will remain more consistent with fewer drafts, better humidity control, enhanced comfort and enhanced energy efficiency.

Cooling Your Home For cooling operation, make sure the System or Mode control is set for Cooling. Then, adjust the Temperature control to your desired setting. Finally, use the Fan control to select Automatic (turns on and off as cooling is needed) or On (runs continuously).

Operation Under Extreme Conditions Your air conditioner will run as long as necessary to maintain the indoor temperature selected on your thermostat. On extremely hot days, your air conditioner will run for longer periods at a time than on moderate days. Your system will also run for longer periods of time under the following conditions:

• Frequent opening of exterior doors

• Operating laundry appliances

• Taking hot showers

• More than the usual number of people present in the home

• More than the normal number of electric lights in use

• Drapes or blinds are open on the sunny side of the home

Before you request dealer service, check for these easily solved problems:
• Check the indoor and outdoor disconnect switches Also check your main electrical panel circuit breakers or fuses.
• Check for sufficient airflow. Air filter(s) should be reasonably clean and interior vents should be open and unobstructed.
• Check thermostat settings. For cooling, your desired temperature setting should be LOWER than the displayed room temperature, and the System/Mode control should be on Cool or Auto. For heating, your temperature setting should be HIGHER than the displayed room temperature, and the System/Mode control is set to Heat or Auto.
• Time delays - depending on the air conditioner you have, there may be delays in unit operation that are built-in to protect the equipment and your comfort. Don't be alarmed if you notice a time delay in operation. It may be a standard protection feature of your equipment. Check with your authorized Dealer for more information on time delays.

If you need to contact your authorized dealer for troubleshooting and/or repairs, be sure to have the model and serial numbers of your equipment available (there are spaces on the cover for you to write this information). With this information, your dealer may be able to offer helpful suggestions over the phone or save valuable time through knowledgeable preparation for the service call.

Excerpt from Carrier Catalog No: OG-ACR410GEN-03

Simple, routine maintenance as described below will enhance your air conditioning system’s ability to operate economically and dependably. Always remember the following safety precautions:

CAUTION! PERSONAL INJURY AND/OR PRODUCT AND PROPERTY DAMAGE HAZARD: Failure to follow this caution may result in personal injury or product and property damage. 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. 

​• Keep Filter Clean 
A clogged or improperly installed air filter on your indoor unit will increase operating costs and shorten the life of the unit. For detailed filter cleaning information refer to indoor unit literature.
• Do Not Block Floor, Wall or Ceiling Vents 
When drapes, furniture, toys or other common household items block vents, the restricted airflow lessens the system’s efficiency and life span.
• Do Not Cover or Block Outdoor Unit 
The outdoor unit needs unrestricted airflow. Do not cover it or place items on or next to it. Do not allow grass clippings, leaves, or other debris to accumulate on the sides or top of the unit. And, maintain a 12” (304.8 mm) minimum clearance between the outdoor unit and tall grass, vines, shrubs, etc.
• Check Condensate Drain 
Your air conditioner removes humidity from your home during the cooling season. After a few minutes of operation, water should trickle from the condensate drain of the indoor coil. Check this occasionally to be sure the drain system is not clogged. Drainage will be limited if you live in a very dry environment.
• Do Not Operate Below 55°F/13°C 
Your outdoor unit is not designed to operate when outdoor temperatures are lower than 55_F/13°C without modification. If operation below this temperature is required, consult your authorized dealer.
• Coil Cleaning 
Your indoor coil is located in a sealed cabinet on your indoor unit and will require minimal cleaning with routine filter maintenance. Longer operating cycles and reduced energy efficiency may indicate the need for a coil cleaning by your authorized dealer.
• Base Pan Drainage 
Periodically check for and remove debris that has settled around the base of your outdoor unit. This will ensure proper drainage of the base pan and eliminate standing water inside the outdoor unit.
• Level Installation 
Your authorized dealer will install the outdoor unit in a level position. If the support base settles or shifts and the unit is no longer level, be sure to re-level it promptly to assure proper drainage. If you notice water or ice collecting beneath the unit, arrange for it to be drained away from the unit.

Regular Dealer Maintenance

In addition to the routine maintenance that you perform, your home comfort system should be inspected regularly by a properly trained service technician. Many dealers offer this service at a reduced rate with a service contract. Some service contracts offer additional benefits such as parts discounts and no additional charge for ”after hours” or emergency service.

Monthly maintenance items and outdoor unit rinsing may be performed by the consumer. All other maintenance items and all service work must be performed by a qualified service technician. Read all waring labels
