Single Package Heat Pump
INTRODUCTION
Your heat pump is a unique, all weather comfort-
control system appliance. The basic operation
of the heating/cooling system is described
and illustrated on page 1 of this manual. The
surprising fact that heat exists in air even at
below-freezing temperatures is actually the
basic law of physics which the heat pump
uses to provide energy saving heating comfort.
At outdoor temperatures of 47° Fahrenheit
(or 8° Celsius), your heat pump can deliver
approximately 2 to 3 units of heat energy per each
unit of electrical energy used, as compared to a
maximum of only 1 unit of heat energy produced
with conventional heating systems. During the
cooling season, the heat pump reverses the fl ow
of the heat-absorbing refrigerant to become an
energy-effi cient, central air conditioner.
