delivered by the blower, decreasing your units effi-  
ciency and increasing operating costs and wear-and-  
tear on the unit and controls.  
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 nor-  
mal comfort level.  
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. Fil-  
ters 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. Fil-  
ter sizes and quantities are shown in the following table.  
Keep windows closed after sundown. While the out-  
door 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 mois-  
ture 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 sur-  
face 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  
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.  
Prior to any of the following maintenance pro-  
cedures, shut off all power to the unit.  
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.  
In order to insure long and trouble free service from  
your system, we recommend periodic inspection,  
cleaning, lubrication and adjustment by your installing  
Dealer/Contractor. Be sure to ask about this service.  
For those buildings with in-house maintenance, please  
follow the instructions listed below to care for your sys-  
tem.

inspected annually. If the motor and wheel are heavily  
coated with dust, they can be brushed and cleaned  
with a vacuum cleaner.

A CONSTANT HEAT  
(4) 16" X 25"  
FILTERS  
Heat pumps have a noticeably cooler supply air tem-  
perature than furnaces. The common practice of over-  
sizing furnaces contributes to an "off-and-on-again"  
operation with short blasts of hot supply air. The heat  
pump system is sized more closely to the heating  
needs of your home. Heat is supplied at a lower tem-  
perature over a longer period of time to provide a more  
constant heat, and it may give you the impression that  
your system "never stops running".

FILTERS  
During the heating cycle, you may notice water running  
off the outdoor coil. Moisture from the air is condensed  
on the outside surface of the coil where it gathers and  
runs off. No need for alarm, your unit has not sprung a  
leak!

OUTDOOR COIL DEFROSTING  
20 TON  
At certain outdoor conditions (low temperature, high  
humidity), frost may build up on the coil of the outdoor  
unit. In order to maintain heating efficiency, the system  
will automatically defrost itself.  
FIGURE 3 - END VIEW LESS FILTER ACCESS  
PANEL 15 AND 20 TON  
REGISTERS  
Water vapor rising from the outdoor unit is normal and  
is an indication of proper operation. The vapor cloud  
will only last for a few minutes. When the defrost cycle  
is completed, the system will automatically switch back  
to heating. Electric heat is automatically energized to  
maintain comfort during defrost.  
Supply and return air registers must be open when the  
unit is in operation. Furniture must not block airflow in  
or out of the registers.  
CONDENSER COIL  
An annual check and cleaning of the outdoor coil  
should be done. Clean any debris and dirt from the out-  
side coil face with a brush being careful not to damage  
the fins. If extremely dirty, a hose can be used to wash  
the coil from the inside out while brushing a soapy solu-  
tion on the outside.  
BEFORE CALLING A SERVICE PERSON  
Check thermostat setting and insure thermostat is  
calling for heat or cooling. Check thermostat for  
lint, etc.  
Check fuses or circuit breakers  
BLOWER ASSEMBLY  
Check filters for excessive dust accumulation  
Even with good filters properly in place, blower wheels  
and motors will become dust laden after long months of
