CIRCULATING AIR SUPPLY

WARNING:

Do not allow combustion products to enter

the return air ductwork or the circulating air

supply. Failure to prevent the circulation of

combustion products into the living space can

create potentially hazardous conditions including

carbonmonoxidepoisoningthatcouldresultin

personal injury or death.

All return ductwork must be secured to the unit

with sheet metal screws. All return ductwork

must be adequately sealed and all joints must be

taped. When return air is provided through the

bottomoftheunit,thejointbetweentheunitand

the return air plenum must be air tight.

Theroofcurborcementpadonwhichtheunitis

mountedmustprovidesoundphysicalsupportof

the unit with no gaps, cracks, or sagging between

the unit and the curb or pad.

Return air and circulating air ductwork must not

be connected to any other heat producing device

such as a ﬁreplace insert, stove, etc. Doing so

mayresultinre,explosion,carbonmonoxide

poisoning, personal injury, or property damage.

Air Ducts

This unit is designed only for use with a supply and return

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 available 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ManualDbytheAir

Conditioning Contractors of America (ACCA).

• Theductsmustbeproperlysizednottoexceedtheunit

maximum ESP rating at 400 scfm per nominal ton of

cooling capacity.

• Ductworkshouldbeattacheddirectlytotheunitanges

for horizontal applications.

• Ifroofcurbisinstalled,theductsmustbeattachedto

the curb hangers, not the unit.

• It is recommended that the outlet duct be provided

with a removable access panel. The opening should

be accessible when the unit is installed in service and

shall be sized so that smoke or reﬂected light may be

observed inside the casing to indicate the presence of

leaks in the heat exchanger. The cover for the opening

shall be attached in a way that will prevent leaks.

• If outside air is utilized as return air to the unit for

ventilation or to improve indoor air quality, the system

must be designed so that the return air to the unit is not

less than 50° F (10° C) during heating operation.

• Ifacombinationofindoorandoutdoorairisused,the

ducts and damper system must be designed so that the

return air supply to the furnace is equal to the return air

supply under normal, indoor return air applications.

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efciency,equipmentdamage

and possible ﬁre.

• This unit is not supplied withair lter(s) and hasno

factory equipped means for accommodating internal

ﬁlter(s). A suitable air ﬁlter must be installed upstream

of the evaporator coil of the return air system. Refer to

Table 1 for recommended ﬁlter sizes.

• Allreturnairmustpassthroughtheltersbeforeentering

the evaporator coil. It is important 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 in unit shutdowns.

• Airlterpressuredropmustnotexceed0.08inchesWC.

• Horizontal and downow Installations require the air

ﬁlter system be installed in the return air ductwork.

NOTE TO INSTALLER: After installing or replacing the

ﬁltration system for this unit, add the following statement

on or adjacent to the lter service panel: “Replace

ﬁlter(s) installed in your system only with the same

dimensional size ﬁlters that are being replaced.”
