NORDYNE warrants the heat pump to be free
from defects in material or workmanship for a
period of one year. A warranty certificate with
full details is included with the heat pump. How-
ever, NORDYNE will not be responsible for any
costs found necessary to correct problems due
to improper setup, improper installation, adjust-
ments, improper operating procedure on the
part of the user, etc.
The heat pump system will heat and cool your
home and save your energy dollars.
During the summer, a heat pump cools a house
by absorbing heat from within the house and
exhaustingitoutdoors. Duringthewinter, aheat
pumpheatsahousebyabsorbingheatoutdoors
and exhausting it indoors. This is an efficient
heating means because you pay for “moving”
heat from outdoors to indoors, but do not pay to
generate the heat.
Some specific examples of service calls which
are not included in the limited warranty are:
1. Correcting wiring problems in the electrical
circuit supplying the heat pump.
