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 warm-up
period with the electrical power connected is necessary
before running the air conditioner again in the spring. If
you forget this warm-up period, you run the risk of
severe equipment damage.
Refrigerant
Your comfort system uses R-410A refrigerant. R-410A
does not contain chlorine and will not harm the ozone
layer in the atmosphere. It is classified as an HFC
(Hydrofluorocarbon).
The EPA has approved R-410A under its Significant
Alternative Policy (SNAP) guidelines. R-410A is envi-
ronmentally “friendly” as it does not harm the ozone
layer in the atmosphere. R-410A systems are the
recognized replacement for R-22 systems in residential
applications.
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.
