Congratulations...
on your purchase of our heat pump. This energy efficient unit has been precision designed, manufactured
of high-quality materials and has passed man y rigorous
inspections and tests to ensure years of satisfactory
performance. Please read this booklet thoroughly . It will
help you understand your heat pump and will tell you
how to operate it efficiently and how to obtain the greatest measure of comfort at the lowest operating
expense. We appreciate your interest in our products
and your decision to purchase our heat pump. Enjoy
your comfort.
This heat pump has been specially developed and built
to meet dual needs of heating and cooling. That’s why
you can rely on efficient, trouble-free operation.
Your system is fully automatic. Set the thermostat and
forget it. And it’s automatically protected against damage by voltage fluctuations or excessive heating or
cooling demands.
GENERAL INFORMATION
HOW YOUR HEAT PUMP WORKS
If your hand is wet and you blow on it, it feels cool
because some of the moisture is evaporating and
becoming a vapor. This process requires heat. The
heat is being taken from your hand, as your hand feels
cool.
820900-UUM-B-0913
The Main power to the system must be kept “On” at all
times to prevent damage to the outdoor unit compressor. If necessary, the thermostat control switch should
be used to turn the system “Off”. Should the main power
be disconnected or interrupted for 8 hours or longer, DO
NOT attempt to start the system for 8 hours after the
power has been restored to the outdoor unit. If heat is
needed during this 8 hour period, use emergency heat.
HEATING CYCLE
With the thermostat in the heating position, and outdoor temperature in the range of 20 - 30 or below, the
outdoor unit will generally run 100% of time.
When the outdoor air is cool and moist, frost may form
on the surface of your outdoor coil. When this frost
builds to a certain point, your system will switch to a
defrost cycle. Although you may feel cooler air coming
from your registers, DO NOT adjust your thermostat.
This frost will melt quickly, and your system will return
to normal operation automatically.
COOLING CYCLE
Switch your thermostat to cool. Select a comfortable
thermostat temperature setting, typically between 75
and 80 degrees. Comfort sensations vary with individuals.The lower the indoor temperature desired, the
greater the number of hours your unit must operate.
That’s what happens with a heat pump. During the
cooling cycle, your system will remove heat and humidity from your structure and w ill transfer this heat to th e
outdoor air.
During the heating cycle, your system will remove heat
and humidity from the outdoor air* and will transfer this
heat to your structure. Re member th at your h eat pump
doesn’t generate much heat, it merely transfers it from
one place to another.
*This is possible because even 0F outdoor air contains a great deal of heat.
SYSTEM OPERATION
Your thermostat puts full control of the comfort leve l in
your structure at your fingertips.
Set your thermostat for heating or cooling. Find the
temperature that is most comfortable for you, and then
leave your thermostat alone. Manually moving the thermostat up or down to extreme settings will not speed
up temperature changes. Avoid moving the thermostat
up during heating - particularly where a demand type
electric meter is installed. This will increase your operating cost substantially.
Set your thermostat 2 or 3
hours before entertaining large groups during hot
weather. People give off considerable heat and moisture.
On an extremely hot day, the indoor temperature may
rise 3 to 6
selected equipment does not have the capacity to
maintain a constant indoor temperature during this
peak load. Over-sizing your system to handle this peak
load isn’t practical because the over-sized system
would operate much less efficiently at all other conditions.

HEATING CONSERVATION
For the most efficient operation, keep storm windows
and doors closed all year long. They not only help to
insulate against heat and cold, but they also keep out
dirt, pollen and noise.
Closing drapes at night and keeping fire place dampers
closed when necessary, will help you to retain the air
you have already paid to heat.

COOLING CONSERVATION
To comfortably cool your home, your heat pump must
remove both heat and humidity. Don’t turn your system
off even though you will be away all day. On a hot day,
your system may have to operate between 8 and 12
hours to reduce the temperature in your home to a normal comfort level.
Keep windows closed after sundown. While the outdoor temperature at night may be lower than indoors,
the air is generally loaded with moisture which is
soaked up by furniture, carpets and fabrics. This moisture must be removed when you restart your system.
The hotter the outside temperature, the greater the
load on your system. Therefore do not be alarmed
when your system continues to run after the sun has
set on a hot day. Heat is stored in your outside walls
during the day and will continue to flow into your home
for several hours after sunset.
Use your kitchen exhaust fan when cooking. One surface burner on “High” requires one ton of cooling. Turn
on your bathroom exhaust fan while showering to
remove humidity. You can also help your system in the
summer by closing drapes or blinds and lowering
awnings on windows that get direct sunlight.
MAINTENANCE
Prior to any of the following maintenance procedures, shut off all power to the unit.
In order to insure long and trouble free service from
your system, we recommend periodic inspection,
cleaning, lubrication and adjustment by your installing

AIR FILTERS
3 THRU 6 TON
Units 3-6 Ton are shipped with 1" throwaway type air filters.
The filter racks on 3-6 ton units will receive 1" or 2" filters. Filters can also be installed in the building at a suitable return
air location if an economizer or outside air accessory is not
used. Filters must always be used. They should be inspected
once a month and thoroughly cleaned or replaced if it
appears they are beginning to accumulate excessive dirt. Filter sizes and quantities are shown in the following table.

To install the filters, remove the filter access panel located to
the left of the condensate drain connection as shown in Figure 1.
NOTE: Filters must be installed with “Air Flow” arrows point-
ing inward -- toward the indoor coil. In the event the
spacers in the filter section are removed, they must
be reinstalled in their original position.
Slide filters all the way into the filter racks provided. When
more than one filter in a filter rack is required, they must butt
each other when sliding into position. Replace the filter
access panel.
