*Electric heater for use with 208/230V, 40FS units only. Refer to Electrical
Data and Wiring, Table 4, for fan section/electric heater usage and com-
plete electric heater model numbers.
tHorizontal application not recommended for Weathermaster IV system.
{Model 40FS220 not for use with 280X coil.
**For use with 38HQ227 and 234 only.
Models 28VQ,HQ coils and 40FS heaters are for
use in cooling-only and/or cooling and electric
heating systems. The 28VQ and HQ coils are also
for use in heat pump systems with 38HQ or 40FQ
electric heaters: Model 28TQ coil is for installation
in 38TQ 2-speed heat pump systems. The 28QX coil
1s for solar-assisted heat pump systems. The 28VH
coll application is with Model 40FS075 only.
Fan section, coil and electric heater are tested
and approved for installation in unconditioned
space per ARI Standard (80 F db, 75 F wb indoor
temperature; 80 F db outdoor temperature). Insu-
late supply and return air ductwork in uncondi-
tioned space. If conditions exceed the ARI Stand-
ard, additional insulation with vapor barrier may
be required for the unit.
Fan Sections 40FS can be positioned to discharge
air upward (upflow), horizontally, or downward
>(downflow), except for sizes 075, 120 which cannot
be used in downflow applications, and are suitable
for “Attic-Type” installations.
The 28 Series Coils are approved as draw-thru
(airflow) units only with the 40FS fan section. Install
coils in draw-thru position; heater in blow-thru
position. Therefore, coil must be attached to air inlet
end of fan section. As indicated in Table 3, per-
mussible coil airflow position(s) in system are:
28TQ — upflow, downflow or horizontal; 28VQ —
upflow or downflow; 28 HQ — horizontal; 28QX —
upflow or horizontal; 28VH002 — horizontal or
> upflow with 40FS075 only, upflow with 40FS120
only.
Assembly of coils to 40FS fan section, electric
heater and filter section is described in this booklet.
For further coil information, see 28 Series installa-
tion data.
COIL CONDENSATE DRAINAGE (for any unit
assembly installed above an occupied or usable
space) — In addition to normal condensate drain
line connection, install an auxiliary condensate pan
under entire unit assembly. Route drain line to any
drain that is visible to occupant. In 28 VH coil appli-
cations, only the drain pan needed should be used.
See 28VH Installation Instructions.
Under prolonged high humidity conditions, elimi-
nator plates may be required on downflow applica-
tions. Horizontal coil installation may also require
special condensate removal methods. See Coil In-
stallation Data.
Accessory Electric Heater is used with 40FS,
208/230-volt fan section. See Electrical Data and
Wiring table for fan section/electric heater usage.
Use electric heater as a blow-thru unit only by
attaching heater to air discharge end of 40FS fan
section in any of the 3 positions. Electric heater
has both heating and cooling controls including a
40-va or 60-va control circuit transformer, indoor
fan relay and low-voltage terminal strip.
MODELS 40FS916320 AND 40FS916500EH,
GM AND HV — These heaters are approved for
downflow usage but require the use of adapters
(downflow support angles) to support fan section
weight. See Installation, Heating Unit Assembly.
Filter Section is shipped taped to air inlet end of
fan section. Filter section includes a reversible
filter rack with 5/8-in. duct connection flanges. On
pita:
3
. most unit assemblies the filter section can be
attached to unit with flanges exposed or turned over
so flanges are inside unit. The permanent one-in.
fılter media pulls out (Fig. 1) for easy removal and
cleaning.
Cooling Control Kit is an accessory for 40FS,
208/230-volt fan sections used in cooling-only in-
stallations. The kit contains a 40-va transformer, fan
deck filler panels, indoor fan relay and low-voltage
terminal strip. See Fig. 11, and cooling control kit
installation on page 9. Because accessory electric
heaters come equipped with cooling controls listed
above (plus required heating controls), a cooling
control kit is not required when electric heater is
used. An accessory humidity control kit is required
for use in 28TQ 2-speed installations. See Step 7
and Fig. 12.
INSTALLATION
Step 1 — Inspect Equipment — File claim with
shipping company if shipment is damaged or
incomplete.
Step 2 — Determine Position of Unit by Air-
flow Direction — See Table 3 and Fig. 2, 3, 4 and
5. Ensure access panels on all units face front before
and after unit assembly.
Step 3 — Assemble Required Unit — Follow
assembly procedure below for required unit. On
downflow unit assemblies, loosen or remove fan
motor mounting bolts and rotate fan motor so
oiling holes are a minimum of 45° above horizontal
center line of motor.
Fasteners for assembling units are shipped in a
bag inside of fan section or inside electric heater
enclosure. Use the no. 10 serrated hex head sheet
metal screws (or equivalent) provided, where indi-
cated in unit assembly instructions below, to ensure
proper electrical ground continuity.

To maintain ductwork clearance on upflow in-
stallations when heater top is within 3 in. of com-
bustible material, set heater spacer plate over heater
discharge air opening. Attach ductwork to heater
flanges, Fig. 9. To maintain ductwork clearance
on downflow installations thru a floor: cut a 16-in. x
12-in. hole thru the floor. Set the spacer plate into
the hole. Place unit into the installed spacer plate
and connect discharge plenum to flanges provided
on heater.
Step 4 — Connect Ductwork to Unit Supply
and Return Air Openings — Duct connection
flanges are provided on fan section when used with
accessory flange deck, cooling coil, electric heater
and filter section, Fig. 1 thru 8. Two instances may
occur when duct connection flanges are not avail-
able for use: when cooling unit or cooling and heat-
ing unit is assembled for downflow cooling or
downflow cooling and heating with filter section
in place (Fig. 8), when filter section is installed
on fan section or cooling coil with its duct connec-
tion flanges in alternate position inside of coil or
fan casing. Field-fabricated duct connections
are then required.
If necessary, refer to Carrier System Design
Manual, Part 2, for system air duct design. It is
recommended that flexible connectors be used
between ductwork and unit to prevent trans-
mission of vibration. (See Ductwork Acoustical

Treatment.) When electric heater is installed, use
heat resistant material for flexible connector
between ductwork and unit air discharge con-
nection. Ductwork passing thru unconditioned
space must be insulated and covered with vapor
barrier. External ductwork must be insulated and
weatherproofed.
UPFLOW RETURN AIR CONNECTION THRU
THE FLOOR — Size floor opening large enough
to accept flanges on filter section. Make duct flush
with floor. Set unit on floor over opening with
filter section flanges inserted thru floor into duct.
Use fireproof resilient gasket 1/8 to 1/4-in. thick
between duct, unit and floor. For downflow supply
air connection thru the floor, proceed as above,
except size floor opening large enough to accept
flanges on unit air discharge connection. (See
combustible material specifications.)
If a side inlet return air connection is required,
use an accessory return air plenum.
ACCESSORY RETURN AIR PLENUM is avail-
able in 2 sizes for use in upflow installations where
side return air inlet is required. A 21-in. wide model,
40FS900-141, is for use with 40FS160 assemblies,
and a 24-1/2 in. wide model, 40FS900-191, is for
use with 40FS200,220 assemblies and 40FS075
assemblies.
Set 40FS heating and/or cooling assembly in
place on top of plenum. Cut opening in either side
or back of plenum and make return air ductwork
connection. Return air plenums and typical in-
stallation are shown in Fig. 10. |
Step 5 — Insulate Ductwork (Thermal and
Acoustical) — Insulate all ductwork passing thru
unconditioned spaces such as hot attics and crawl
spaces. Heat gain due to ductwork transmission
can result in insufficient air supply temperatures at

duct outlets. Metal duct systems that do not have
one 90% elbow and 10ft of main duct to first
branch takeoff require internal acoustical insula-
tion lining per the following specifications:
Line the inside of plenum, branch runs and
main duct with acoustical insulation in accordance
with the latest edition of SMACNA (Sheet Metal
and Air Conditioning Contractors National Asso-
ciation) application standard for duct liner. Duct
liners should be UL classified batts and blankets
with a fire hazard classification marking of
FHC-25/50 or less. Ensure main duct lining 1s
extended 6 to 8 ft down the duct from plenum.
As an alternate to above, fibrous glass ductwork
may be used if constructed and installed in
accordance with the latest edition of SMACNA
construction standard on fibrous glass duct.
Both acoustical lining and fibrous ductwork shall
comply with National Fire Protection Association
as tested by UL Standard 181 for Class I air ducts.

ELECTRICAL DATA AND WIRING
Field wiring must comply with local and national
fire, safety and electrical codes. Voltage to
unit must be within + 10% of voltage indicated on
nameplate (voltage range at which the units will
operate satisfactorily for limited periods of time).
Contact local power company for correction of
improper line voltage.
ane
See Tables 4 and 5 for recom
fuse sizes.
Step 8 — Install a Branch Circuit Disconnect
Switch(es) per NEC. One disconnect switch 1s
required on all unit assemblies except those
which include 40FS916320 (11- to 20-kw) electric
heaters. Standard assemblies using these heaters
require 2 disconnect switches for 2 line power
circuits. If one line power circuit, using one dis-
connect, is required, attach an accessory line power
connection conversion lug set (Lug Adapter Kit —
Part No. 40FS900271) to fuse terminals in electric
heater. Installation may be aided by first attaching
adapter lugs to wire then positioning lugs to fuse
block. See Fig. 13C.
Locate disconnect(s) within sight from and readily
accessible from the unit, per section 440-14 of
National Electrical Code (NEC). |
Step 9 — Route Line Power Leads Into Unit —
Extend leads from disconnect per NEC thru hole
provided (Fig. 1) into cooling control kit or acces-
sory electric heater. (Cooling control kit not
required when heater is used.)
Step 10 — Connect Ground Lead(s) to the
Ground Screw in Cooling Control Kit or
Grounding Lug in Electric Heater Control
Section for safety. Connect power wiring, Fig. 13.
Splice power leads to pigtails in cooling control kit
or connect leads to fuse terminals or terminal board
on electric heater.
When using control kit, splice a power lead to
black transformer pigtail on 230-volt units or red
transformer pigtail on 208-volt units. Cap unused
transformer pigtail.
When using an electric heater on 230-volts,
connect the red transformer pigtail to heater line
voltage terminal. When using heater on 208-volts,

Cap unused transformer pigtail.
For splice connections or capping pigtails, use
wire nuts provided. Tape each connection.
Three-speed fan motor on all units (except Model
40FS075) may be connected for high, medium or
low fan speeds as described below. Refer to Table 7
for minimum allowable fan speeds when electric
heaters are used.
Step 11 — Set Fan Motor Speed(s) — High,
medium or low fan speed leads are provided on
motor for choice of fan speeds. Motor leads are
factory connected to fan speed selector block
located on fan housing (Fig. 11 and 13). Selector
block terminal 1 is high fan speed, terminal 2 is
medium fan speed and terminal 3 1s low fan speed.
Model 40FS075 utilizes terminals 1 and 2 only.
Line power leads are supplied with cooling
control kit and electric heater for connection to
fan speed selector block as directed in Fig. 13.
Route yellow and black power leads which
extend thru hole in back of cooling control kit to
selector block. Route yellow and black or yellow,
black and red power leads from electric heater thru
power openings (Fig. 15) in bottom of heater
casing and fan section deck to selector block.
One fan speed may be selected for cooling only
unit assembly, heating only or cooling and heating
unit assembly when 40FS916320 or 40FS916500
heater 1s used.
Two fan speeds may be selected for remaining
combined cooling and heating assemblies; a heating
speed and a cooling speed. (See Table 7 for
Minimum Fan Speeds on heating application.) For
single fan speed operation on these heating only or
10
heating and cooling assemblies, remove red lead
from heater fan relay terminal 5 or 6. Connect a
black jumper (supplied) between fan relay terminal
6 and fan relay terminal 4 (40FS,FQ916, or
38HQ9000 heaters) or terminal 5 (40FS,FQ920, or
38HQ9001 heaters). Connect black heater lead to
fan speed selector block for speed required. See unit
label diagram for details.

Step 12 — Connect Control Power Wiring
(24-volt) with Cooling Control Kit or Electric
Heater — Use 40- or 60-va transformer supplied
as part of cooling control kit or electric heater
controls as 24-volt supply for system. A one-
transformer control wiring hookup 1s recommended
for ease of installation. When outdoor unit trans-
former is used together with control kit (or heater)

LUBRICATION — Where oil holes are provided,
remove oil plugs and add 8 drops of SAE 20
nondetergent oil at start of every cooling season.
Replace oil plugs. When motor is removed, reinstall
so that oil holes are at least 45 degrees above
horizontal. Motors without oil holes are factory
lubricated for life of motor.

so that rear drops slightly, allowing assembly to
pass thru front of unit.
8. Reassembly is the reverse of the above pro-
cedure. Note that when reassembling, rear
flange of blower outlet sits on top of fan deck,
tab on forward edge of outlet engages slot in
front of fan deck. |
Cleaning — Remove caked-on dirt from fan wheel
and housing with brush; remove grease with mild
solvent. When replacing blower assembly, ensure
fan wheel is centered in housing.
Return Air Filter — Pull rings (Fig. 1) are provided
for removing l-in. permanent filters. Inspect filter
frequently. Clean filter with a vacuum cleaner or
wash with mild soap and water solution.
A steel rod acting as a media support 1s
imbedded in the filter. Replace filter so that
support prevents media from being drawn into fan
during operation.

ELECTRIC HEATER SERVICE
See Fig. 15 for component location. All service
can be completed with heater in place. Ensure all
power is shut off before servicing.
Limit Switch malfunction prevents heating
element from coming on or causes fusible link to
blow. Replace switch if malfunction occurs.
Sequencer malfunction will cause heater not to
come on or never to shut off — replace sequencer.
Transformer — (40- or 60-va) supplies 24-volt
power for control circuit. Replace transformer if
faulty.
Fan Relay malfunction will cause unit fan not to
run or run continuously — replace relay.
For replacement items use Carrier Specified Parts.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
