1. GENERAL INFORMATION
Standard cased coils are designed for upflow/
downflowapplicationsorhorizontalapplications
when used in conjunction with our horizontal
drain pan kit (See page 5). Accessory kits are
not required for factory ready horizontal coils.
Coils are equipped with braze type refrigerant
connections for easy installation.
Read the installation manual supplied with the
outdoor unit for refrigerant line connection pro-
cedure,requiredlinesizes,andotherinformation
pertaining to the system installation.
1. Refer to the Installation Instructions of the
outdoorunitforconnectionofthe additional
components of the IQ drive system.

2. Make certain that the air delivery of the
furnace/air handler is adequate to handle
thestaticpressuredropofthecoil,filter,and
duct work.
3. Where precise forming of the refrigerant
lines is required, a copper tubing bender
designed for the size lines used is recom-
mended.Avoid sharp bends and contact of
the refrigerant lines with metal surfaces.
4. Refrigerant lines should be wrapped with
pressure sensitive neoprene or other suit-
able material where they pass through the
raw edges of holes.
5. Coil must be level for proper condensate
drainage.

3. COIL INSTALLATION
WARNING:
Electricfurnacesmaybeconnectedto
more than one supply circuit.
Upflow Furnace —
1. Disconnect all electrical power to the fur-
nace.
2. If needed, use one of the coil case adapter
kits to match the coil to the furnace air dis-
chargeopening.RefertotheCoilSpecifica-
tions Section for proper kit numbers.
3. Install the coil and level it as needed to
ensure proper condensate drainage. (See
Figure 2)
4. Seal the enclosure as required to minimize
air leakage.
5. Connect the refrigerant lines as outlined in
the Refrigerant Lines section.
Downflow — These coils may be installed in
downflow applications. Installation of the coils
intheseapplicationsonlyrequirethatthefurnace
andcoilcabinetsaresecurelymountedtogether
before setting in place.
To Configure Horizontal Ready Coils for
Horizontal LEFT Installations:
1) Remove the coil access door.
2) IMPORTANT:Remove theplug fromoneof
the threaded holes in the horizontal drain
pan.Completelyremovethewebbinglocated
inthethreaded holesofthe horizontaldrain
pan.Ifwebbingisnotremoved,thedrain will
not function properly and ceiling damage
may occur.
3) Inserta plug(fromthehorizontaldrainpan)
into the open and unused drain hole in the
drain pan at the bottom of the unit to block
bypass air.
4) Removethecorrespondingdrainlineknock-
outfromthecoilaccessdoortoallowaccess

5) Replace the door.
To Configure Horizontal Ready Coils for
Horizontal RIGHT Installations:
1) Remove the coil access door.Unscrew the
line-set tube close-off plate from the front
left cabinet rail.
2) Slide the coil and drain pan assembly out
of the unit.
3) IMPORTANT: Remove the plug from one of
thethreadedholesinthehorizontaldrainpan.
Completelyremovethewebbinglocatedinthe
threaded holes of the drain pan. If webbing
is not removed, the drain will not function
properly and ceiling damage may occur.
4) Remove the sheet metal hairpin covers
(if supplied) from the back of the coil and
discard.
5) Place the horizontal drain pan on the oppo-
site side of the coil. On units with 2 sets of
knockouts,removetheothersetofknockouts

6) Inserta plug(fromthehorizontaldrainpan)
into the open and unused drain hole in the

7) Slide the coil and the horizontal drain pan
assembly back into the unit. Reattach the
tube close off plate.
8) Removethecorrespondingdrainlineknock-

Note:All condensate pans have primary and
secondary drain connections to meet FHA
requirements. If the application is located in
or above a living space where damage may
result from condensate overflow,a separate
3/4 inch drain must be provided from the
secondarydrainconnectionandasecondary
drain pan must be installed under the entire
unit. Run secondary drain lines to a place
where they are noticeable if used.
4. REFRIGERANT LINE
CONNECTIONS
Line Connections:
1. Remove the protective caps from the coil
andrefrigerantline setandalsoremovethe
holegrommetsandtubeclose-offinsulation
from around the tubes.
2. Cut the line set tubing to the proper length.
Be sure that the tubing has been sized in
accordance with the outdoor unit specifica-
tions.
3. Inspect both refrigerant lines. The ends of
the lines must be round, clean, and free of
any burrs.
4. Insert the line set tubes into the coil tube
stubs until they bottom out.
5. Braze the individual connections with dry
nitrogen flowing through the joints to elimi-
nate internal oxidation and scaling.
NOTE:Itisrecommendedtowrapawetrag
around both the suction line and liquid line
of the air handler while brazing to prevent
damage to internal components unique to
the IQ DriveTM System.
6. Check the assembly for leaks with dry
nitrogen.
7. On horizontal applications re-position the
sensing bulb on the suction line so it is in
the 4 o'clock or 8 o'clock position on the
suction tube.
5. COMPLETINGTHE
INSTALLATION
Condensate Drain:
CAUTION:
The indoor coil must be checked to
ensurealevelinstallation.Failuretodo
somayresultinimpropercondensate
disposal, causing structural damage,
premature equipment failure, or pos-
sible personal injury.
1. The coil condensate pan is furnished with
3/4" NPSC drain connections. Use a PVC
or similar material fitting to attach the drain
line to the pan. The fitting should be hand
tightenedonly. Overtighteningmaycrack
the drain pan and cause a condensate
leak.
2. Connect the drain line and run to a suitable
drain avoiding sharp bends and pinching of
theline. Installacondensatetrapandprime
with water.
3. During the system checkout, inspect the
drain line and connections to verify proper
condensate disposal.
Air Filter — Air filters are not provided as an
integral part of this coil, however, a filter must
be installed upstream of the coil and inspected
frequently.Whenthefilterbecomescloggedwith
dustorlint,itshouldbereplaced(disposabletype)
orcleaned (washabletype). The filtershould be
inspectedandreplacedorcleanedatleasttwice
during the year, generally at the start of each
heating and cooling season.
Close-OffPlatesand Panels—Installthenec-
essaryairclose-offplatesaroundtherefrigerant
lines and drain line where required. Reinstall
all inner and outer panels of the coil case and
furnace that were previously removed to install
the indoor coil.
Refrigerant Charging — These cased indoor
coils are not factory charged with refrigerant.
It will be necessary to evacuate the indoor coil
andlinesetpriortocharging.Refertotheoutdoor
unitinstallationmanualfordetailed chargesand
instructions.
6. MAINTENANCE AND SERVICE
WARNING:
Ensure that all electrical power to the
furnaceandoutdoor(condensing)unit
is off before performing any mainte-
nance or service on the system.
To ensure optimum performance and to mini-
mize possible equipment failure, the following
periodic maintenance should be performed on
this equipment:

1. Theairfilterinstalledwiththesystem should
be checked and cleaned or replaced twice
per year.
2. Check the coil, drain pan, and condensate
drain line for cleanliness at the start of
each heating and cooling season.Clean as
needed.
CAUTION:
