YOUR COMFORT SYSTEM
A. Identifying Your System
Take the time to familiarize yourself with your packaged heat pump type of system. This knowledge will be of use in understanding the basic
operation of your new heat pump. The unit has a rating plate affixed to it which provides necessary information for specific identification of a unit.
You should familiarize yourself with the product, model, and serial numbers listed on each rating plate. Record them for future reference in the
space provided at the end of this booklet.
IMPORTANT FACTS
To better protect your investment and to eliminate unnecessary calls, familiarize yourself with the following facts:
1. Your heat pump system should never be operated without a clean air filter properly installed. Plan to inspect the filter periodically. A
clogged air filter will increase operating costs and shorten the life of the unit.
2. Supply-air and return-air registers should not be blocked. Drapes, furniture, and toys are some of the items commonly found obstructing
registers. Restricted airflow lessens the unit’s efficiency and life span.
3. The outdoor unit must have unrestricted airflow. Do not cover the unit, lean anything against it, or stand on it. Do not allow grass clippings,
leaves, or other debris to accumulate around on top of the unit. Maintain a 30-in. minimum clearance between the outdoor unit and tall grass,
vines, shrubs, etc.
4. Your multipurpose indoor thermostat is the control center for your heat pump system. You should familiarize yourself with its proper
operation. Attempting to control the system by other means—for instance, switching the electrical supply power ON and OFF—may cause
damage to the unit (See Fig. 3).
5. During heating, increasing the thermostat setting more than 2 degrees may cause the supplemental heaters to be turned on for a short period
of time to satisfy the thermostat. Needless use of the supplementary heat reduces potential energy savings.
6. You may find that you can maintain greater personal comfort by running the fan continuously. “Air pockets” can form due to the structure
of the house, placement of registers, etc. air pockets may be too cool or warm for your liking. Continuous fan operation minimizes any
temperature differences. Also, systems equipped with electronic or mechanical air cleaners and/or humidifiers offer the added benefits of
having the air continuously cleaned year-round and humidified during the winter season.
7. Your heat pump will remove humidity from your home during the cooling season. After a few minutes of operation, you should be able
to see water trickle from the condensate drain. Check this occasionally to be sure the drain system is not clogged. Of course, don’t expect
to see much drainage if you live in a very dry environment.
8. During the heating cycle, air from your registers may seem cooler than you might first expect. This is because your heat pump delivers a
constant flow of air at around 90˚F to 105˚F instead of sudden bursts of hot air as with a conventional furnace. This air may feel cooler
because it is slightly less than your skin temperature. However, it is sufficiently warm to keep you comfortable.
9. Ice or frost will tend to form on the coil during the winter heating operation. Your heat pump is designed to automatically melt the ice. When
in this defrost cycle, it is normal for steam or fog to rise from the outdoor unit. Do not be alarmed!
10. Do not operate your unit in cooling mode when outdoor temperatures are below 55˚F unless your unit was modified for low-ambient
operation.
11. Do not operate your unit in heating mode when outdoor temperatures are above 66˚F unless you set your thermostat to emergency heat
mode.
WARNING: FIRE AND ELECTRICAL HAZARD
Failure to follow this warning could result in personal injury, death and/or property damage.
To prevent serious injury, death, or property damage, read and follow all instructions and warnings, including labels shipped
with or attached to unit before operating your new heat pump.
The operation of your heat pump system is controlled by the indoor thermostat. You simply adjust the thermostat and it maintains the indoor
temperature at the level you select. Most thermostats for heat pump systems have 3 controls: a temperature control selector, a FAN control, and
a SYSTEM or MODE control.
B. Cooling Mode
When operating in cooling mode, your heat pump will run in cooling mode until the indoor temperature is lowered to the level you have selected.
On extremely hot days, your heat pump will run for longer periods at a time and have shorter “off” periods than on moderate days.
OPERATING YOUR HEAT PUMP

OFF
Fig. 3—Main Electrical Disconnect
The following are typical conditions that add extra heat and/or humidity to your home. Your heat pump will work longer to keep your home
comfortable under these conditions:
1. Entrance doors are frequently opened and closed
2. Laundry appliances are being operated
3. A shower is running
4. More than the usual number of people are present in the home
5. More than the normal number of electric lights are in use
6. Drapes are open on the sunny side of the home
C. Heating Mode
With the SYSTEM or MODE control of your indoor thermostat set to HEAT, your heat pump will run in heating mode until room temperature
is raised to the level you have selected. Of course, your heat pump will have to operate for longer periods to maintain a comfortable environment
on cooler days and nights than on moderate ones.
D. Defrost Mode
When your heat pump is providing heat to your home and the outdoor temperature drops below 45˚F, moisture may begin to freeze on the surface
of the coil. If allowed to build up, this ice would impede airflow across the coil and reduce the amount of heat absorbed from the outside air. So,
to maintain energy-efficient operation, your heat pump has an automatic defrost mode. The defrost mode starts at a preset time interval of 60
minutes. Defrost will start at the preset time only if the ice is sufficient to interfere with normal heating operation. After the ice is melted from
the coil, or after a maximum of 10 minutes in defrost mode, the unit automatically switches back to normal heating operation.
Do not be alarmed if steam or fog appears at the outdoor unit during defrost mode. Water vapor from the melting ice may condense into a mist
in the cold outside air. During certain weather conditions such as heavy snow and freezing rain it is not uncommon for ice to build up on the unit
grille. This is normal for these weather conditions. Do not attempt to remove the ice from the unit grille. This condition will not affect the proper
function of the unit and will clear a few days.
E. Emergency Heat Mode
This allows your supplemental heating source to keep your home or office warm until your heat pump can be serviced. Also, if the electricity to
your heat pump has been off for more than 30 minutes, switch your thermostat to EHEAT mode before restarting your heat pump. Leave the system
in EHEAT mode for an amount of time equal to the power outage. It is not necessary to exceed 12 hrs. (If you cannot determine how long the
power has been off, leave the system in EHEAT mode for 8 hrs.)
A92135
With the proper maintenance and care, your heat pump will operate economically and dependably. Maintenance can be accomplished easily by
referring to the following directions. However, before performing maintenance, consider these important safety precautions:
WARNING: ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury and/or death.
Disconnect all electrical power to the indoor air handler or furnace before removing access panels to perform any
maintenance. Disconnect power to both the indoor and outdoor units. Note: There may be more than 1 electrical disconnect
switch.
CAUTION:
Failure to follow this caution may result in personal injury.
Although special care has been taken to minimize sharp edges in the construction of your unit, to avoid injury be extremely
careful when handling parts or reaching into the unit.
PERSONAL INJURY HAZARD
PERFORMING ROUTINE MAINTENANCE
—3—
F. Check the Air Filter
A dirty air filter will cause excessive strain on the compressor and blower motor. This can cause the components to overheat and automatically
shut down. In the worst case, the components will fail and need to be replaced. To avoid inefficient or failed operation of your unit, CHECK THE
FILTER(S) EVERY 3 MONTHS. Replace filter(s) when necessary, or clean the filter(s) if you have the reusable type.
Disposable filters should be replaced by similar, new filters of the same dimensions.
Reusable, permanent filters should be washed in a solution of cold water and mild detergent, then rinsed and thoroughly dried. THE FILTER
MUST BE COMPLETELY DRY BEFORE BEING REINSTALLED. To avoid prolonged shutdown of your unit while a filter is drying, you
should have an extra filter on hand. This allows you to rotate between the two with minimal downtime for your comfort system. Extra filters may
be purchased from your dealer.
The filters(s) and filter rack for a packaged system are supplied and installed by the contractor or dealer. Typically, the filter(s) and rack are located
in the return-air duct at the outdoor unit or behind the return-air grille(s). Have your dealer show you the location of your filter(s) and the
procedures for removal and replacement.
If your system includes a high efficiency or electronic air cleaner, refer to air cleaner User’s Manual for proper filter cleaning or replacement.
G. Outdoor Coil
If grass clippings, leaves, shrubbery, and debris are kept away from the unit, minimal care should be sufficient to keep the system functioning
properly. However, if the outdoor coil becomes dirty, use a vacuum cleaner or shop vac with soft brush attachment to clean the exterior surface.
Vacuum coil surface using an up and down motion. Be careful not to bend or damage fins.
If dirt is deep in the coil, contact your dealer for service. Do not attempt this yourself.
H. Outdoor Coil—Sea Coast
If your unit is located near the ocean, special maintenance is required. Ocean mist/breeze carries salt, which is corrosive to most metals. Although
your new unit is made out of galvanized metal and is protected by top-grade paint, you should take the precaution of additional maintenance which
consists of periodically washing the unit. By washing all exposed surfaces and coil, you will be adding additional life to your unit. Please consult
your installing contractor for proper intervals/procedures for your geographic area or service contact.
I. UNIT SUPPORT
Your packaged heat pump unit should be maintained at a level position. If its support should shift or settle so that the unit is no longer level, you
should correct the condition. Relevel it promptly to assure water drains out of the unit. If you notice that water or ice collects beneath the unit,
arrange for it to be drained away from the unit.
BEFORE YOU REQUEST A "SERVICE CALL"
CHECK FOR THESE EASILY SOLVED PROBLEMS:
1. Check the indoor and outdoor disconnect switches. Verify that circuit breakers are ON or that fuses have not blown.
2. Check for sufficient airflow. Check the air filter(s) for any accumulations of dirt. Check for blocked return-air or supply-air registers. Be
sure registers are open and unobstructed.
3. Check the settings on your indoor thermostat. If you desire cooling, make sure that the temperature control selector is set below room
temperature and the SYSTEM or MODE control is set to COOL or AUTO. If you require warmth, make sure that the temperature control
selector is set above room temperature and the SYSTEM or MODE control is set to HEAT or AUTO. The FAN control should be set to
ON for continuous blower operation or AUTO if you wish blower to function only while your heat pump is operating. If your comfort
system still fails to operate, turn your system off and contact your servicing dealer for troubleshooting and repairs. Specify your apparent
problem, and state the model and serial number of your equipment. (You should have them recorded on the last page of this booklet.) With
this information, your dealer may be able to offer helpful suggestions over the phone or save valuable time through knowledgeable
preparation for the service call.
REGULAR DEALER MAINTENANCE
In addition to the routine maintenance that you perform, your home comfort system should be inspected regularly by a properly trained service
technician. The inspection (preferably twice each year, but at least once every year) should include the following:
1. Routine inspection of air filter(s). Replacement or cleaning as required.
2. Inspection and cleaning of the blower wheel, housing, and motor as required.
3. Inspection and, if required, cleaning of coils.
4. A check of all electrical wiring and connections.
5. A check for secure physical connections of individual components within unit.
6. Operational check of the heat pump system to determine actual working condition. Necessary repair and/or adjustment should be performed
at this time.
7. Your servicing dealer may offer an economical service contract that covers seasonal inspections. Ask for further details.
You have purchased a PH3Z series unit. Be sure to read the warranty at the back of this booklet carefully to determine the coverage for your unit.
Record the model, product, and serial numbers of your new equipment in the spaces provided. This information, along with the other
ready-reference facts requested will be necessary should you ever require information or service.
