ABOUT THE AIR CONDITIONER
The P6 Series single packaged convertible air conditioner
is a high efficient self contained cooling unit that will cool
your home year round and provide energy saving comfort.
Additional features and benefits of the P6 air conditioner
include:
• Indoor and outdoor coils are designed to optimize heat
transfer, minimize size and cost, and increase durability
and reliability.
• Environmentally friendly R-410A Refrigerant.

AIR CONDITIONER MAINTENANCE
Proper maintenance is most important to achieve the best
performance from the appliance and should be performed
frequently at the beginning of each air conditioning season.
OPERATING INSTRUCTIONS
Cooling Operation
1. Set the thermostat's system mode to COOL or AUTO
and change the fan mode to AUTO. See Figure 1.
2. Set the temperature selector to the desired
temperature level. The outdoor fan, compressor, and
blower motor will all cycle on and off to maintain the
indoor temperature at the desired cooling level.
Heating Operation
(If optional heat accessory is installed)
1. Set the thermostat's system mode to HEAT or AUTO
and change the fan mode to AUTO. See Figure 1.
2. Set thetemperature selector to a desired temperature
level. The indoor blower willcycle on and off to maintain
the indoor temperature at the desired heating level.
Turning the Air Conditioner OFF
Change the thermostat's system mode to OFF and the fan
mode to AUTO (See Figure 1). NOTE: The system will not
operate, regardless of the temperature selector setting.
Operating the Indoor Blower Continuously
The continuous indoor blower operation is typically used to
circulate the indoorair toequalize atemperature unbalance
due to a sun load, cooking, or fireplace operation.
Set the thermostat fan mode to ON (Figure 1). The indoor
blower starts immediately, and will run continually until
the fan mode is reset to AUTO.
WARNING:
Your Air Conditioner contains liquid and gaseous
refrigerant under pressure. Installation and
servicing should only be attempted by qualified,
trained personnel thoroughly familiar with the
equipment and safe responsible refrigerant
handling procedures. Failure to comply with
this warning could result in equipment damage,
personal injury, or death.
• Keep the outdoor unit clean. Hose off periodically and
keep unit fins clear of leaves and grass clippings.
• Keep the outdoor unit clear of obstructions.
DO NOT obstruct airflow with tall plants or shrubs. DO
NOT store gasoline or other flammable materials on
or near the outdoor unit.
• Never operate the appliance without a filter installed in
the return airduct. Inspect filters frequently and replace
when necessary with filter of same dimensional size.
Before You Call a Technician:
• Check the thermostat setting. Make sure the system
mode and temperature settings are correct.
• Check the electrical panel for tripped circuit breakers.
• Check the filters for dust accumulation.
• Check the outdoor unit and make sure it is clean and
not covered with grass or leaves.

duct. Air ducts should be installed in accordance with
the standards of the National Fire Protection Association
Standard for Installation of Air Conditioning Systems
(NFPA 90A), Standard for Installation of Residence Type
Warm Air Heating and Air Conditioning Systems (NFPA
90B), and all applicable local codes. NFPA publications
are avaialable by writing to: National Fire Protection
Association, Batterymarch Park, Quincy, ME 02269 or
visit www.NFPA.org on the web.
• Design the duct work according to methods described
bythe Air Conditioning Contractors of America (ACCA).
• The ducts must be properly sized and not exceed .2"
W.C. pressure drop at 400 scfm per nominal ton of
cooling capacity.

Air Filter Requirements
WARNING:
Never operate the unit without a filter in place.
Dust and lint could accumulate on internal parts,
resulting in loss of efficiency, equipment damage
and possible fire. Replace disposable filters with
the same type and size.
= Air filter(s) are not supplied and must be installed Jn
the unit or inthe return air system by the installer. Only
three phase units are equipped with an internal filter
rack assembly.
= If using an Economizer or Fresh Air Equipment, the
factory installed filter rack must be removed prior to
installation. See page 8 for removal instructions.
= All return air must pass through the filters before
entering the unit. Recommended filter sizes are listed in
Table 1.NOTE: Itisimportant that all filters be kept clean
and replaced frequently to ensure proper operation of
unit. Dirty or clogged filters will reduce the efficiency
of the unit and result Jnunit shutdowns.
= Air filter pressure drop must not exceed 0.08 inches
WC. When replacing the air filters, a suitable air filter
must be installed upstream of the evaporator coil of
the return air system.
= Downflow installations require an internal filter
accessory kit to be installed.
= Horizontal installations require the air filter system be
installed in the return air ductwork.

AIR CONDiTiONER INSTALLATION
Packaging Removal
Remove the shipping carton and User's Manual from
the equipment. Take care not to damage the tubing
connections when removing the carton. For rooftop
installations, remove and discard the two supports
attached beneath the unit.
Rigging and Hoisting
WARNING:
To avoid the risk of property damage, personal
injury, or death, it is the rigger's responsibility
to ensure that whatever means are used to hoist
the unit are safe and adequate:
The lifting equipment must be adequate for the
load. Refer toTable 4 (page 14) for unit weights.
The unit must be lifted from the holes in the
base rails using cables or chains.
Spreader bars are required to protect the unit
and ensure even loading.
Keep the unit in an upright position at all times.
The rigging must be located outside the units
center of gravity. Refer to Figure 9 (page 14)
for locating the center of gravity.
All panels must be securely in place during
rigging and hoisting.
Minimum Clearance Requirements
P6SD units are certified as cooling equipment for
outdoor installation only. Figure 2 (page 6) displays the
minimum clearances to obstructions for both Downflow
and Horizontal discharge.
Units may be installed on wood flooring or on Class A,
B, or C roof covering material when used with bottom
supply and return air ducts. If using bottom discharge
with return air ducts, a roof curb must be installed prior
to unit installation. See Rigging and Hoisting section for
setting of the unit.
Ground Level
Ground level installations must be located according to
local building codes or ordinances and these requirements:
= Clearances must be in accordance with those shown
in Figure 2.
= A suitable mounting pad (Figure 3, page 8) must be
provided and separate from the building foundation.
The pad must be level to ensure proper condensate
disposal and strong enough to support the unit's weight.
The slab height must be a minimum of 2" (5cm) above
grade and with adequate drainage.
= Allow sufficient clearances for access to the internal
filter rack.
