It is the sole responsibility of the homeowner tomake certain that heat pump has been correctlyset up and adjusted to operate properly.
NORDYNE warrants the heat pump to be freefrom defects in material or workmanship for aperiod of one year. A warranty certificate withfull details is included with the heat pump. How-ever, NORDYNE will not be responsible for anycosts found necessary to correct problems dueto improper setup, improper installation, adjust-ments, improper operating procedure on thepart of the user, etc.
Some specific examples of service calls whichare not included in the limited warranty are:
1. Correcting wiring problems in the electricalcircuit supplying the heat pump.
WINTER HEATING
1. Outdoor air enters the heat pump.2. The cold, heat-transfer section (outdoor coil)
extracts the heat from the air as the refrigerantevaporates from a liquid to a cold gas.
3. The refrigerant, compressed to a hot gas bythe heat pump, carries the heat to the heat-transfer section (indoor coil).
4. The hot, heat-transfer section (indoor coil)releases the heat as the refrigerant condensesfrom a gas to a liquid.
5. The blower circulates the heat throughoutthe home via the supply duct.
6. The refrigerant returns to the outdoor coil andevaporates once again to absorb more heat.
SUMMER COOLING
1. Indoor air enters the return air duct.2. The cold, heat-transfer section (indoor coil)
extracts the heat from the air as the refrigerantevaporates from a liquid to a cold gas.
3. The refrigerant, drawn to the heat pump andcompressed to a hot gas, carries the heatoutdoors.
4. The hot, heat-transfer section (outdoor coil)releases the heat as the refrigerant condensesfrom a gas to a liquid.
5. The heat pump (outdoor fan) discharges theheat to the outside air.
6. The refrigerant returns to the indoor coil andevaporates once again to absorb more heat.

3. Adjusting or calibrating of thermostat.
To avoid misunderstandings at a later date,carefully review these responsibilities with yourdealer or service company.
The heat pump system will heat and cool yourhome and save your energy dollars.
During the summer, a heat pump cools a houseby absorbing heat from within the house andexhausting it outdoors. During the winter, a heatpump heats a house by absorbing heat outdoorsand exhausting it indoors. This is an efficientheating means because you pay for “moving”heat from outdoors to indoors, but do not pay togenerate the heat.

OPERATING INSTRUCTIONS
To Operate Your Heat Pump For Cooling —
1. Set the thermostat system switch to COOLand the thermostat fan switch to AUTO. (SeeFigure 1)
2. Set the thermostat temperature selector tothe desired cooling temperature. The outdoorunit fan, the indoor blower, and thecompressor will all cycle on and off to maintainthe indoor temperature at the desired coolinglevel.
NOTE: If the thermostat temperature level is re-adjusted, or if the thermostat system switch is re-positioned, the outdoor unit fan and thecompressor may not start immediately. Aprotective timer circuit holds the compressorand the outdoor fan off for approximately sixminutes following a previous operation or theinterruption of the main electric power
To Operate Your Heat Pump For Heating —
1. Set the thermostat system switch for HEATand the thermostat fan switch to AUTO. (SeeFigure 1)
2. Set the thermostat temperature selector tothe desired heating temperature. The outdoorunit fan, the indoor blower, and thecompressor will all cycle on and off tomaintain the indoor temperature at the desiredheating level.
NOTE: If the thermostat temperature level is re-adjusted, or if the thermostat system switch is re-positioned, the outdoor unit fan and thecompressor may not start immediately. Aprotective timer circuit holds the compressorand the outdoor fan off for approx-imately sixminutes following a previous operation or theinterruption of the main electrical power.
Emergency Heat — Some thermostats willinclude a system switch position termed EM HTor AUX HT, etc. This is a back-up heating modeto be used only if there is a suspected problem.With the system switch set to EM HT, etc., thecompressor and outdoor fan will be locked offand supplemental heat (electric resistanceheating) will be used as a source of heat.Sustained use of electric resistance heat inplace of the heat pump will result in an increasein electric utility costs.
Figure 1. Typical Thermostat
Defrost — During cold weather heatingoperation, the outdoor unit will develop a coatingof snow and ice on the heat transfer coil. This isnormal and the unit will periodically defrost itself.During the defrost cycle, the outdoor fan willstop, while the compressor continues to run andheat the outdoor coil, causing the snow and iceto melt. During defrost, there may be somesteam rise from the outdoor unit as the warm coilcauses some melted frost to evaporate.
