General Information
Electrical Power Supply
Many outdoor units include a crankcase heater. This small heater warms the oil in the compressor for im- proved lubrication. Once the needed temperature has been reached, most of these heaters will shut off automatically.
These heaters work effectively, but not rapidly. If your outdoor unit has a crankcase heater and the power has been disconnected from your outdoor unit for more than two hours, you must connect electrical power to the outdoor unit for at least four hours before setting the thermostat so as to cause the unit to come on.
Not all outdoor units have crankcase heaters. If you are not certain whether yours does or not, contact your dealer.
If your outdoor air conditioning (not heat pump) unit does have a crankcase heater, you may wish to shut it off in the fall after cooling season is completely over. To do this, simply open the disconnect switch which is near the outdoor unit, or turn the proper circuit breaker at the electrical panel to the OFF position. This could save you a small amount of your winter electrical bills. If you choose to do this, remember - a four hour
Refrigerant
Your comfort system uses
The EPA has approved
When your comfort system is operating properly, the refrigerant is contained within airtight passages. No refrigerant escapes into the atmosphere during normal operation.
When repair or replacement of your comfort system becomes necessary, it is essential that you hire a qualified servicer to perform the work. A qualified servicer will have the tools and training necessary to ensure that EPA regulations are followed. U.S. residents who ignore or intentionally violate the EPA regulations are in violation of the law, and may be subject to fines or other penalties.
