COOLING
Carrier’s cooling only duct-free split
systems are a matched combination of
an outdoor condensing unit and one
of 3 decorative indoor fan coil units
connected only by refrigerant tubing and wires. One of the 3 fan coil
choices will fit any application you
might encounter.
The fan coils can be mounted on
the wall, at the ceiling, or in the ceiling. This selection of fan coils permits
inexpensive and creative solutions to
design problems such as:
• add-ons to current space (an office
or family room addition)
• special space requirements (a computer room)
• when changes in the cooling load
cannot be handled by the existing
system (when adding heat-generating
equipment to a currently conditioned space)
• when adding air conditioning to
spaces that are heated by hydronic
or electric heat and have no
ductwork
• historical renovations or any application where preserving the looks
of the original structure is essential

These compact indoor fan coil units
take up very little space in the room
and do not obstruct windows. The fan
coils are attractively styled to blend
with most room decors. Advanced
system components incorporate innovative technology to provide reliable
cooling performance at high efficiencies and low sound levels.
Carrier’s duct-free split systems
offer the solution of choice. The compressor is outdoors, linked by refrigerant lines to an indoor fan coil located
directly in the room it will cool. These
systems have minimal impact on
the existing structure, and the design
and interior of the conditioned space
is not compromised by bulky ductwork. Because of these features, Carrier’s duct-free split systems can be
installed in places where conventional
ducted cooling simply cannot go.
Low sound levels
When noise is a concern, the ductfree split systems are the answer
because you don’t have to worry about
duct design. There are no compressors indoors, either in the conditioned
space or directly over it, and there is
none of the noise usually generated by
air being forced through ductwork.
The indoor units are whisper quiet.
The outdoor units operate at sound
levels as low as 6.6 bels, and are the
perfect answer to sound level
ordinances.
When sound ordinances and proximity to neighbors demand ultraquiet operation, the 38HDC and
38AN are the right choices: The advanced, horizontal airflow design distributes air more evenly over the coil.
On 38HDC units, the coil also acts
as an extra sound-supressing device
before the air is discharged at a very
low velocity.
High efficiency
With SEERs (seasonal energy efficiency ratios) up to 12.0, the Carrier
duct-free split systems save energy
and may qualify for utility company
rebates in some areas.
Secure operation
If security is an issue, outdoor and indoor units are connected only by
refrigerant piping and wiring to prevent intruders from crawling through
ductwork. In addition, since 38HDC
and 38AN units can be installed 6 in.
away from outside walls, coils are
protected from vandals and severe
weather.

Fast installation
Carrier’s compact duct-free split systems take only a few hours to install, since only wire and piping need
to be run. The fast and easy installation ensures minimal disruption
to customers in the home or workplace. This is an added advantage of
Carrier’s duct-free split systems, especially in retrofit situations.
Features like mounting brackets and
templates make the unit very easy to
install. In fact, the ceiling-suspended
units are furnished with indoor-tooutdoor connecting cables.
Simple servicing and
maintenance
Removing a single panel on outdoor
units provides immediate access to the
isolated compressor and control
compartment, allowing a service technician access to check unit operation without a loss of condenser
airflow. In addition, on 38HDC units,
the blow-thru design of the outdoor
section means that dirt accumulates
on the inside surface of the coil. Coils
can be cleaned quickly from the outside using a pressure hose and detergent without removing grilles or
using fin combs.
On indoor units, service and maintenance expense is reduced due to
easy-to-change cleanable filters on all
units. In addition, the high wall and
ceiling-suspended systems have extensive self-diagnostics to assist in
troubleshooting. All units have easyaccess coils and cleanable condensate
pans to assist in meeting indoor air
quality standards.
Both refrigerant service valves are
brass, front-seating type with sweat
(38HDC) or flare (38AN) connections.
The valves are externally located so
refrigerant tube connections can be
made quickly and easily. Each valve
has a service port for ease of checking
operating refrigerant pressures (38HDC
units). Internal service ports are also
provided to make servicing even
easier.
Built-in reliability
Carrier duct-free split system indoor
and outdoor units are designed to provide years of trouble-free operation.
The high wall indoor units include
protection against freeze-up and high
discharge temperatures. Other indoor units are protected by outdoor
unit controls. All systems include selfdiagnostics to ensure reliability.
Carrier’s 38HDC condensing units
are the only dedicated commercial
units with all safety features standard
to ensure high performance and
lasting reliability under the most
demanding situations. For example,
an accumulator safeguards the
compressor against loss of lubrication,
while start capacitors and relays
(non-scroll units) assure dependable
start-ups, especially during low voltage
conditions down to 187 v. Highand low-pressure safety switches, liquid line filter drier, and lock-out
protection are standard on most sizes
and Time Guardt compressor protection can be included.
NOTE: Time Guard compressor protection is an accessory when condensing unit is matched with 40QAB
or 40QKB fan coil units. Compressor start-up delay through the controller is standard for these units and
the 40QNB unit.

Features/Benefits (cont)
The totally-enclosed condenser-fan
motor means greater reliability under rain conditions, ensuring dependable performance for many years.
Individual room comfort
Maximum comfort is provided because
each space can have individual set
points and may be controlled based
on actual usage. The air sweep feature
provided on high wall and ceilingsuspended systems permits optimal
room air mixing to eliminate hot and
cold spots to enhance occupant
comfort.
In addition, year-round comfort can
be provided by combining standard
cooling outdoor units with heat pump
versions of the in-ceiling and ceilingsuspended fan coil units. This combination provides electric heating
capability.
Economical operation
Carrier’s duct-free split system design
allows individual room cooling only
where required. There is no need
to run large supply-air fans or chilled
water pumps to handle a few spaces
with unique load patterns. In addition,
because air is moved only in the
space required, no energy is wasted
moving air through ducts.
Features like the permanent splitcapacitor type motors provide more
economical operation, and the rifled
copper tube with louvered aluminum plate fin coil provides maximum
heat transfer.
Lightweight, compact size
The small footprint of these units provides additional benefits. Carrier’s
exclusive aeroacoustics makes these
units the most compact in the industry.
Because they require minimal service
and airflow clearances, condensing
units can be located virtually anywhere
— on the ground, roof, balcony,
under a deck, or even mounted to an
outside wall.
The outdoor unit can be mounted
on any type or weight roof, and the
indoor units take up little valuable,
rentable space. Because they are ductfree, not having to run large ductwork leaves additional space to be
rented or utilized, making the building
even more profitable.
In addition, the small size makes
these units easily moveable. When
floor plans change, the units can be
quickly reinstalled.
Easy-to-use controls
The microprocessor-based control in
the high-wall unit is easy to use,
permitting easy changes for maximum
comfort. The microprocessor offers
the ultimate in comfort and efficiency.
All units automatically restart and
retain their memories after a power
failure, eliminating unnecessary service
calls and service disruption. High
wall units are equipped with a wireless
remote controller. Under-ceiling and
in-ceiling cassette units use standard 24 v controls with new solid-state
multi-featured electronic thermostats. All units can be easily integrated
into most building control systems.
Wide range of accessories
Customizing the Carrier duct-free split
systems to your application is easily
accomplished through the many accessories available. Low-ambient temperature capability (permitting cooling
operation down to –20 F outdoor
ambient) is easily added on all units.
Accessories for the high wall and
ceiling-suspended fan coils include an
internal condensate pump to provide installation flexibility. Condensate
pumps are standard on in-ceiling
cassettes. Ventilation-air capability is
available as an accessory on ceiling suspended units and in-ceiling
cassettes. In addition, limited ducting
capability is available to connect
in-ceiling cassettes (for example, to
duct to an adjacent room).

CONDENSATE PUMPS
Condensate pumps provide condensate lift capability of 20 in. on
ceiling-suspended (40QAB) fan coils. On high wall fan coils, condensate pump has a lift capability of 1 to 10 ft (009 unit) or 3 to 25 ft
(012-024 units). The pump mounts inside the unit with quick plug-in
connections, and is recommended when adequate drain line pitch
cannot be provided.
NOTE: This pump is standard on the in-ceiling cassette (40QKB) fan
coils, where it provides a lift capability of 20 in. above the condensate pan.
FRESH AIR INTAKE KIT
Fresh air intake kit provides for a variable amount (up
to 30%) outdoor-air capability for the ceiling-suspended
(40QAB) and cassette (40QKB) fan coils. The filter is
mounted at the fan coil unit and provides filtering of
outdoor air before it enters the unit. (Ceiling-suspended
system application is shown.)
8
CHARCOAL FILTER KIT
The charcoal (carbon) filter kit is available for duct-free high wall fan
coil units. This accessory improves indoor air quality by removing
volatile organic compounds (VOCs), odors, and micro-particles from
the air. The filter kit can be installed either before or after the unit
has been mounted to the wall. Filters must be changed approximately every three months.

Accessories (field installed) (cont)
Condensing units
Low-ambient kit includes a solid-state head pressure controller designed to control condenser fan cycling, and is activated by a pressure sensor. It is specifically designed to
control fan-motor cycles in response to saturated condensing pressure. This device maintains a constant saturated condensing temperature of 100 F ± 10 F at outdoor-air temperatures between 55 F and –20 F, and can be used on all
38AN and 38HDC condensing units without changing the
condenser-fan motor.
Winter start control is an SPST delay relay. The control
bypasses the low-pressure switch for approximately 3 minutes to permit start-up for cooling operation under low load
conditions at low-ambient temperatures. This relay is recommended on all 38HDC systems that have the accessory
low-ambient kit. Winter start control can also be used to
provide low-ambient cooling at outdoor ambient temperatures between 55 F and 40 F.
Liquid solenoid valve is an electrically operated shutoff
valve that is installed at the outdoor unit to stop and start
refrigerant flow in response to compressor operation. The
valve maintains a column of refrigerant in the liquid line between compressor operating cycles and is required for certain long-line applications and to improve system performance. The valve should be used with 38HDC030 and 036
units to achieve maximum efficiency and on all long-line
applications (over 100 ft).
Crankcase heater is available for units with scroll compressors. Heater clamps onto compressor oil sump. Recommended for low-ambient applications.
Field fabricated accessories
Field fabricated accessories including the stacking kit, snow
or ice stand, wind baffles, and wall mount brackets must be
constructed in the field using field-supplied materials. For
drawings, contact your Carrier representative.
10
Stacking rails allow stacking of equally-sized units or permit smaller units to be stacked on top of larger units. These
field fabricated rails can be used for stacking all 38HDC018
and larger units.
Snow or ice stands raise the outdoor unit above snow
and ice surfaces to permit normal air circulation, condensate drainage, and maintenance clearances in areas where
prolonged subfreezing temperatures or heavy snowfalls occur. The snow rack/ice stand must be field fabricated and
can be used on all 38HDC condensing units.
Wind baffle is a field fabricated sheet metal wrapper used
to provide improved unit operation during high winds, and
is recommended for 38HDC units whenever the low-ambient
accessory is used.
Wall mount brackets are mounted to the outside of the
structure to raise unit from ground level, or to mount the
unit on a wall adjacent to a sloping roof. Wall mounts are
also useful in areas of heavy snowfall or where space is at a
premium. Wall mounts must be field fabricated and can be
used with any 38HDC unit.
Fan coils
Indoor guard is a decorative wire guard for the ceilingsuspended (40QAB) fan coils. The guard mounts over the
fan coil discharge to prevent objects from entering the unit
and air sweep.
Electronic programable thermostats are available for
in-ceiling cassette (40QKB) and ceiling-suspended (40QAB)
fan coils. These commercial-grade thermostats provide 7-day,
4 event-per-day scheduling. The integral subbase provides
3-speed fan switchover capability, air sweep, auto changeover, and non-volatile memory (no battery required).

Selection procedure (with example)
I Determine the type of fan coil which best suits
the application (refer to Systems Index table on
page 26).
Duct-free split systems have 3 types of fan coils with
overlapping capacities to choose from. Select the system type which best meets the job conditions. This example uses a 2-ton ceiling-suspended fan coil (assume
wall space is not available for a wall-mounted unit).
II Determine cooling load requirements at design
conditions.
Required Load Conditions:
Required cooling capacity (TCG) . . . . . 23,500 Btuh
Sensible Heat Capacity (SHC) . . . . . . . 16,000 Btuh
Temperature Air Entering
Condensing Unit . . . . . . . . . . . . . . . . . . . . . . . . 95 F
Temperature Air Entering
Indoor Unit (EAT.) . . . . . . . . . . . . 82 F db/68 F wb
db — dry bulb
wb — wet bulb
III Select system that satisfies load requirements.
Enter the Systems Index table on page 26 at ceilingsuspended system for 24,000 Btuh, and select the system that best approximates cooling requirements.
System index no. 6 with a nominal net capacity of
22,800 Btuh cooling is the system selected. The system consists of a 38HDC024 outdoor unit matched
with one 40QAB024 indoor unit.
IV Determine if system selected satisfies cooling requirements.
Enter Cooling Capacities table on page 32 at high speed
and 95 F outdoor entering air temperature (EAT, air
entering condenser). By interpolation, at 68 F EAT,
the system gross capacity is 23,680 Btuh cooling
[(25,200 – 23,300) x (1/5) + 23,300], and
14,980 Btuh SHG (gross sensible capacity). Adjust the
SHG in accordance with Note 2 of the Combinations
Ratings table, using the correction factor for an 82 F
EWB (entering air wet bulb), and a .04 BF (bypass factor). The result is an adjusted SHG of 16,141 Btuh.
The total gross cooling capacity of 23,680 Btuh and
the sensible capacity of 16,141 Btuh satisfy stipulated
load requirements.
V Determine net cooling capacity and system energy efficiency ratio.
Determine net cooling capacity (refer to Cooling Capacity table for System 6 on page 32). Net total cooling capacity must be interpolated as follows:
(24,700 - 22,800) x (1/5) + 22,800 = 23,180 Btuh
To determine the energy efficiency ratio (EER), system
kW must be interpolated from the Cooling Capacity
table for System 6 in the same manner:
(2.09 - 2.07) x (1/5) + 2.07 = 2.07 kW
Then calculate EER:
Net Cooling Capacity
EER =
kW x 1000
23,180
= 11.2 EER
2.07 x 1000
NOTE: The SEER (Seasonal Energy Efficiency Ratio)
CANNOT be calculated for this system. SEERs can only
be found as a direct result of testing at specified ARI
conditions. See ARI Capacities table on page 6.
VI Determine the recommended liquid and vapor
line sizes.
Refer to Refrigerant Line Sizing section on page 47.
NOTE: With long-lines applications, it may be necessary to adjust cooling capacity. See Long-Lines Applications section on page 48 for more details.

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The SHG is based on 80 F edb temperature of air entering indoor
coil.
Below 80 F edb, subtract (corr factor x cfm) from SHG.
Above 80 F edb, add (corr factor x cfm) to SHG.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The SHG is based on 80 F edb temperature of air entering indoor
coil.
Below 80 F edb, subtract (corr factor x cfm) from SHG.
Above 80 F edb, add (corr factor x cfm) to SHG.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

1. Direct interpolation is permissible. Do not extrapolate.
2. The SHG is based on 80 F edb temperature of air entering indoor
coil.
Below 80 F edb, subtract (corr factor x cfm) from SHG.
Above 80 F edb, add (corr factor x cfm) to SHG.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).

Application data
Unit selection
Select equipment to either match or be slightly less than
anticipated peak load. This provides better humidity control, fewer unit cycles, and less part-load operation.
For units used in spaces with high sensible loads, base
equipment selection on unit sensible load, not on total anticipated load. Adjust for anticipated room wet bulb temperature to avoid undersizing equipment.
When selecting equipment which has outdoor air introduced into the unit, determine the mix conditions of room
air and outdoor air at design conditions. The cooling capacity tables in this literature are based on 80 F edb. Adjust
for actual dry-bulb and wet-bulb conditions with the required
outdoor air to select the proper equipment.
Unit combinations and coil mixed matches
The 38AN and 38HDC units are the only units approved
for use with the Carrier 40QNB, 40QAB, and 40QKB ductfree split systems. The 38AN and 38HDC units can also be
used with other fan coil units.
Mixed matches of indoor-fan coil capacity more than one
size larger than the outdoor condensing unit capacity may
result in inadequate indoor comfort. Do not select mixed
matches where the indoor-fan coil capacity is more than
one size larger than the outdoor condensing unit capacity
unless specifically indicated in this data. Heat pump fan coils
can be used with cooling-only condensing units to provide
electric heat capability.
Unit mounting (outdoor)
Unit leveling — For reliable operation, units should be
level in all planes.
Clearance — Adequate clearance must be provided for
airflow. See dimensional drawings for proper clearances.
The condensing units are designed for free-blow application. Air inlets and outlets should not be restricted. Outdoor
fan external static pressure available is less than
0.1 in. wg.
Unit location — Cooling units may be stacked 2 high.
Units may be wall mounted, pad mounted at ground level,
roof mounted, or mounted on or under a deck or patio. Be
sure water from roof does not drain directly onto the unit.
See your Carrier representative for drawings to construct
stacking rails or wall mounting brackets.
If 38HDC condensing units are being mounted near a
wall, the condenser air should discharge toward the wall.
This will provide inherent coil protection and the best possible sound and airflow performance. The 38AN units should
be mounted with fan discharge pointing away from the wall.
Unit mounting (indoor)
Unit leveling — For reliable operation, units should be
level in all planes. The 40QAB ceiling-suspended fan coils
may have a slight pitch, but only toward the drain
connection.
Clearance — Provide adequate clearance for airflow. The
unit return and discharge should not be obstructed by furniture, curtains, or anything which may cause unit short cycling or air recirculation. See base unit dimensional drawings on pages 18-24 for required clearances.
46
Unit location — When selecting unit location, select a location which will provide the best air circulation for the room.
40QNB HIGH WALL UNITS — These units should be positioned as high as possible on the wall for best air circulation. Allow adequate clearances above the unit for servicing
(removing unit covers). Place the unit in the middle of the
wall selected (if possible). Select an outside wall if available
to make piping easier, and place the unit so it faces the
normal location of room occupants.
40QAB CEILING-SUSPENDED UNITS — These units should
be mounted near the ceiling and against a wall. The unit
should be centered in the room for best performance. Locating the unit on an outside wall will make piping easier,
but units can also be mounted away from a wall if desired.
(If the unit is mounted away from a wall, the rear panel of
the unit may need a field-supplied trim strip for improved
appearance.) Locate the fan coil return over an area which
is not normally occupied for quietest operation. Do not block
air discharge for a minimum of 15 ft to prevent dumping of
cold air and drafts.
40QKB IN-CEILING CASSETTE UNITS — These units
should be mounted in the ceiling, preferably near the center of the room. If the unit must be mounted near a wall,
close the air discharge on the blocked side(s). (Up to 2 sides
may be blocked.) Locate the control box away from the
blocked side(s).
Mounting template
The 40QAB and QNB fan coil units are furnished with
mounting templates or mounting plates to mark the location of the mounting brackets, wiring, and refrigeration line
hole locations. In addition, the 40QAB units indicate the
location of ventilation-air connections.
Support
Adequate support must be provided to support the weight
of all fan coils. Refer to the Physical Data section on
page 11 for fan coil weights, and the base unit dimensional
drawings on pages 18-24 for the location of mounting
brackets.

Low-ambient operation
Units can operate in cooling down to 55 F under all conditions without a low-ambient kit.
Units equipped with accessory low-ambient kits should also
be equipped with accessory wind baffle, crankcase heater,
and winter start kit.
Winter start — The use of a winter start control may extend the operation range (generally to 35 F or 40 F) without addition of the low-ambient kit. Winter start bypasses
the low-pressure switch for 3 minutes, and is not required
on 38AN units.
Crankcase heater — Scroll compressor units with lowambient control should be equipped with crankcase heaters
to prevent refrigerant migration during compressor off
cycle.
Metering devices
38AN units — The 38AN units have capillary tubes for
refrigerant metering located in the outdoor condensing unit.
These units may only be used with 40QNB fan coils of the
same size.
38HDC units — The 38HDC units use a piston-type metering device located in the indoor unit.
NOTE: All Carrier duct-free split systems use Type ‘‘B’’
Chattleff style AccuRatert pistons. DO NOT mix Type ‘‘A’’
and Type ‘‘B’’ pistons. See Long-Lines Applications section on page 48 for changes in piston sizes due to long
lines.
Drain connections
Install drains to meet local sanitation codes. If adequate gravity drainage cannot be provided, unit should be equipped
with accessory condensate pump. High wall fan coil unit
condensate pumps have a 1 to 10 ft lift (009 size) or
3 to 25 ft lift (012-024 sizes). All other fan coil units have
a lift capability of 20 in. above the condensate pan level.
See base unit dimensional drawings on pages 18-24 for
drain locations and sizes.
NOTE: High wall fan coil units have internal condensate
traps. All other fan coil units require a field-supplied external condensate trap.
Drain connections may be routed through alternate locations on most fan coils. See base unit dimensional drawings on pages 18-24 for possible alternate locations.
Electric heat — The in-ceiling and ceiling-suspended
systems can provide electric heat by using the heat pump
General refrigerant line sizing:
1. All charges, line sizing, and capacities are based on runs
of 25 ft. For runs over 25 ft (38HDC only), consult longlines section on page 48 for proper line sizing, charge,
and AccuRater refrigerant metering device sizing.
NOTE: For runs less than 25 ft, some of the charge may
need to be removed to obtain the correct system superheat. The minimum line length should be 8 ft.

2. Refrigerant lines should not be buried in the ground. If it
is necessary to bury the lines, not more than 36 in. should
be buried. Provide a minimum 6-in. vertical rise to the
service valves to prevent refrigerant migration.
3. The vapor line must be insulated. Use a minimum of
1⁄2-in. thick insulation. Closed-cell insulation is recommended in all long-line applications.
4. Special consideration should be given to isolating interconnecting tubing from the building structure. Isolate the
tubing so that vibration or noise is not transmitted into
the structure.
38AN UNITS
1. The 38AN units are shipped with a full charge of R-22
refrigerant. Check the charge using the superheat method.
Since all refrigerant lines are on the low side of the system, it is not normally necessary to add or remove charge.
2. The 38AN units have mixed-phase refrigerant flow in
the liquid line. DO NOT install a filter drier in the
liquid line. The liquid line must be insulated.
3. No line size changes should be made on 38AN units.
38HDC UNITS
1. The 38HDC units are shipped with a full charge of R-22
refrigerant. Charge is based on fan coil with smallest
charge and 25 ft of line. See System Piston Guide and
Refrigerant Charges on page 48 for system charges. Add
additional charge by weight as necessary and check the
charge with a superheat calculator.
2. For the 38HDC units, install the filter drier provided with
the unit in the liquid line. Use of a field-supplied moisture indicator is also recommended.
47
Application data (cont)
Long-lines applications, 38HDC units:
1. Liquid lines on all 38HDC units should be 3⁄8 in. only.
DO NOT resize liquid lines for additional length.
2. When sizing vapor line, determine line length by finding
equivalent ft of pipe. Equivalent line lengths equal the
linear length (measured length) of the interconnecting
vapor tubing plus losses due to elbows (see Fitting Loss
in Equivalent Ft For Elbows table on page 49). If the
number of elbows is not yet known, assume 50% additional length for equivalent length. In determining line
size, be sure oil can be properly returned to the compressor. Consult the Carrier System Design Guide for
proper oil return recommendations. For line lengths from
25 to 49 ft, no special piping requirements are normally
required. Adjust charge to required amount by adding
charge per Step 7 on page 50 and checking superheat.
For line lengths over 50 ft:
1. A crankcase heater should be added to scroll compressor units (all non-scroll compressor units have crankcase
heaters as standard). Crankcase heaters help prevent
refrigerant migration to the compressor during the off
cycle.
2. Any time the equivalent line length is over 100 ft, a liquid line solenoid must be used. A liquid line solenoid may
also be required for vertical lift applications over 25 ft.
See Step 6 on page 50.
3. A field fabricated accessory wind baffle is recommended.
4. The Effective Capacity Loss table on page 49 provides
the estimated percentage of nominal cooling capacity
losses based on the standard required vapor line size versus what is selected for long-line applications.
a. Select the desired vapor line size from the Effective
Capacity Loss table based on equivalent ft and desired vapor line size.
b. Subtract the nominal percentage loss from the unit
cooling capacities for the given indoor and outdoor
combination.

5. Changes in piston size — The metering device for a longline application must be adjusted to compensate for the
frictional losses due to the long refrigerant lines, refrigerant line accessories, and indoor coil above or below
the outdoor unit. The AccuRatert refrigerant metering
device piston may need to be changed to provide this
adjustment. The AccuRater piston should be changed
for the indoor unit depending upon system configuration and line length. Use the Change in Indoor Unit Piston Size for Elevation table on next page to determine
correct AccuRater piston size. The standard piston size
is shown in the System Piston Guide and Refrigerant
Charges table on page 48.
a. Horizontal configuration — If the total equivalent horizontal length is 100 ft or longer, the indoor piston
must be increased one full piston size, in addition to

6. Liquid line solenoid and tubing configuration — The solenoid has a flow arrow stamped on the valve body. When
the valve is closed (not energized) and pressure is applied
in the direction of the flow arrow, complete shut off will
occur. If pressure is applied against the direction of the
arrow, leakage through the valve will occur. When determining the proper location for a solenoid in a system
liquid line, consider both flow direction and location of
the valve in the system. See the diagram below for proper
location, and install as follows:
a. Horizontal configuration (see figure below) —
1) Install a liquid line solenoid valve within 2 ft of the
fan coil with the flow arrow pointing toward the
indoor unit if equivalent ft of piping is 100 ft or
more.
2) Slope the vapor line toward the indoor unit to provide for refrigerant migration protection during the
off cycle due to temperature differences caused by
slight elevation changes between indoor and outdoor units.
NOTE: When installing a liquid line solenoid, a lowvoltage transformer may be required.

b. Elevated configuration — Indoor unit installed above
the outdoor unit (see figure at right):
1) If there is over 25 ft of lift, a solenoid valve is required in the liquid line.
2) The maximum elevation difference is 65 ft, and
the maximum equivalent ft of piping is 200.
3) Install an inverted trap in the vapor line. The top
of the trap must be above the top of the fan coil.
This prevents the refrigerant from collecting in the
vapor line.

c. Lowered configuration — Indoor unit installed below
the outdoor unit (see figure below):
1) For lines shorter than 100 ft, no solenoid valve is

2) The maximum elevation difference is 150 ft, and
the maximum equivalent ft is 200.
7. Additional charge — The unit should be charged by
weighing in the appropriate charge. Add charge based
on the actual length of line which is over 15 ft of liquid
line. Add 0.58 oz of refrigerant per 1 ft increase over
the 15 ft line to the charge listed in System Piston Guide
and Refrigerant Charges table on page 48.

Controls — systems using high-wall
fan coils (53QNB)
WIRELESS CONTROLLER
Control system — The 40QNB unit is equipped with a
microprocessor control which operates the system. This control is located in the control box of the fan coil unit, with
thermistors located in the fan coil inlet and on the indoor
coil. These thermistors monitor system operation and control the operating mode. To change settings or modes of
operation, use the factory-supplied infrared wireless remote
controller (see above). This controller allows the fan coil unit
to be operated from within the same room without any wire
connections to the unit.
The remote controller includes a wall-mounted bracket.
To install the bracket, attach bracket to the wall using factorysupplied, double-sided tape. Install factory-supplied batteries into the remote controller and place the controller into
the bracket so that it is ready for use.
Operating mode memory — After the system is turned
off or after a power failure, the system remains in the last
operating mode selected. When the system is turned back
on, or when power is automatically restored, operation continues in the same operating mode as when power shut
down.
Automatic operation (Auto) mode — If auto mode is
selected, the system automatically switches the operating
mode to cooling, depending on the selected temperature.
Operating fault diagnosis — The system includes an automatic diagnosis feature which is activated under difficult
or unacceptable operating conditions. If such conditions
occur, the system stops automatically, the operating fault
signal appears (green ‘‘UNIT ON’’ light on the front of the
fan coil unit flashes), and an analysis of the system operating conditions is initiated. The system is restarted automatically as soon as normal conditions have been restored, or it
will remain off. If the system does not start again, the green
‘‘UNIT ON’’ light flashes an error code.
Microprocessor control operation — This system is controlled by a microprocessor designed to give optimum levels of comfort and operating efficiency. The control is located in the 40QNB unit. To operate the unit, the factorysupplied remote controller is required.
There are 9 operating modes (including the off mode) for
the unit. Each mode operates as follows:
• Off Mode — When the unit is in the off mode, all functions (compressor, outdoor fan, indoor fan, and air sweep)
are off.
• Air Circulation Mode (Fan Operation Only) — When air
circulation mode is selected, the indoor fan operates continuously at the selected speed (high, medium, low, or
auto). If the auto mode is selected, the indoor fan operates at low speed. The compressor and outdoor fan are
off.
• Cooling Mode — When the cooling mode is selected, the
indoor fan operates continuously at the selected speed if
the speed is high, medium, or low. If the indoor fan is in
auto mode, the fan changes operating speeds depending
on the difference between the room temperature and the
set point. The compressor cannot run for 3 minutes from
the time the system starts up or for 3 minutes from the
time the compressor last operated. When the temperature of the room is equal to or greater than the selected
temperature, the compressor and outdoor fan will operate until the room temperature is 2° F below the set point,
and then shut off. When the room temperature is less
than the selected temperature, the compressor and outdoor fan remain off.
• Maximum Dehumidification Mode — When the dehumidification mode is selected, the indoor fan operates continuously at the selected speed if the speed is high, medium, or low. If the indoor fan is in auto mode, the fan
changes operating speeds depending on the room temperature. If the room temperature is below the set point,
the indoor fan runs at ultra-low speed, and the compressor could run for up to 4 minutes. (Ultra-low speed is a
control-driven speed [not user configurable] used to sample
the space when the fan would normally be off.) The compressor cannot run for 3 minutes from the time the system starts up or for 3 minutes from the time the compressor last operated.
Initial Operation — When the mode is first selected, one
of the following occurs:
1. If the room temperature is above or equal to the selected
temperature, the unit operates for 16 minutes and the
compressor and outdoor fan operate. The indoor fan
will operate as in the cooling mode. After
16 minutes of operation (or when the room reaches
2° F below set point), the unit switches to normal dehumidification operation.
59
Controls — systems using high-wall
fan coils (53QNB) (cont)
2. If the room temperature is below the selected temperature, the unit operates for 8 minutes as follows: The compressor and outdoor fan will operate for 3 minutes. The
indoor fan will operate at low speed, and 30 seconds
after the compressor stops, the indoor fan stops. The
unit remains off for 1 minute, and then the indoor fan
starts at ultra-low speed for 30 seconds. The unit then
switches to normal dehumidification operation.
Normal Operation — One of the following will take place:
1. When the temperature of the room is equal to or greater
than the selected temperature (by not more than 3° F),
the unit will operate for 8 minutes as follows: the compressor and outdoor fan will operate for 3 minutes. The
indoor fan will operate at low speed, and 30 seconds
after the compressor stops, the indoor fan stops. The
unit remains off for 1 minute, and then the indoor fan
runs at ultra-low speed for 30 seconds. The normal dehumidification operation is repeated for the newly sensed
room temperature.
2. If the room temperature is equal to or greater than the
selected temperature, but not by more than between
4° F and 6° F, the compressor and outdoor fan operate
for 4 minutes. The indoor fan runs at ultra-low speed
and will stop 30 seconds after the compressor stops.
After 3 minutes, the indoor fan runs at ultra-low speed
for 30 seconds. The normal dehumidification operation
is repeated for the newly sensed room temperature.
3. When the room temperature is equal to or more than
4° F below the selected temperature, the system operates as follows: The compressor and outdoor fan operate for 3 minutes. The indoor fan operates at ultra-low
speed and will stop 30 seconds after the compressor
stops. After 4 or 5 minutes, the indoor fan starts at ultralow speed for 30 seconds. The normal dehumidification
operation is repeated for the newly sensed room temperature. If the room temperature is still 4° F below the
selected temperature, the compressor, outdoor fan, and
indoor fan remain off. After 71⁄2 minutes, the indoor fan
operates at ultra-low speed for 30 seconds. The normal
dehumidification operation is repeated for the newly
sensed room temperature.
• Sleep Mode — The sleep mode timer will turn the unit
off when the timer reaches zero minutes. The durations
that can be selected are 1, 2, 3, or 7 hours. After the
initial 30 minutes, the user set point shifts approximately
1° F warmer. This sequence repeats itself every 40 minutes up to a total of 150 minutes.
When in sleep mode the display on the remote controller
is dimmed.
60
• Awake Mode — The awake timer will turn the unit on
when the timer reaches zero minutes. The unit starts in
the same mode and at the same selected temperature as
when the system shut off. If the room temperature is not
within approximately 5 F of the set point 40 minutes before start-up, the unit runs before the awake timer reaches
zero to achieve the set point temperature at start-up.
• Automatic Operation Mode for Cooling Only Systems —
The unit samples the air in the room. Based on the room
temperature, the unit selects one of the following modes:
1. Cooling Mode — If the room temperature is more than
82.4 F with a preset temperature of 78.8 F.
2. Dry Mode — If the room temperature is more than
75.2 F and less than 82.4 F with a preset temperature
of 77 F.
3. Fan Only Mode — If the room temperature is less than
75.2 F.
The preset temperature can be changed by ±4° F using
the remote control.
• Test Mode — The test mode can be selected by setting
the slide switch on the fan coil unit to TEST position. The
slide switch is located on the front of the unit. The fan
coil unit will start immediately (there is no compressor
time delay when using test mode) in cooling mode with
an infinitely low set point. The indoor fan speed will be
at the high setting, and the swing louvers will be on (moving up and down).
NOTE: The unit cannot be controlled by the remote controller until the slide switch is returned to the REMOTE
position.
• Emergency Mode — This mode is only to be used if the
remote controller is lost, damaged, or the batteries are
discharged. To initiate emergency mode, manually move
the slide switch on the fan coil unit to the EMER position. The unit is automatically operated in cooling mode
according to room temperature. Emergency operation settings are as follows:
1. Operation mode: AUTO
2. Fan Speed: AUTO
3. Cooling set point: 77 F
4. Timer Mode: Continuous
NOTE: The unit cannot be controlled by the remote controller until the slide switch is returned to the REMOTE
position.

Operating mode memory
After the system is turned off or after a power failure, the
system remains in the last operating mode selected. When
the system is turned back on, or when power is automatically restored, operation continues in the same operating
mode as when the system shut down.
Automatic air sweep
All units are equipped with an automatic air sweep feature
which automatically directs the airflow louvers up and down
to provide optimum room air circulation. If the auto sweep
feature is not desired, temporarily start the auto sweep using the remote thermostat (press Air Sweep button). When
the louvers are in the desired position, turn auto sweep off
(press Air Sweep button again) to hold them in that
position.
Operating sequence
Ceiling-suspended and cassette fan coil units have a relay
board which controls system operation in response to a room
thermostat. The user may manually select any one of 3 fan
speeds for unit operation. Systems may be equipped with
an accessory power ventilation kit and/or condensate pump.
Fan operation — Fan speed can be selected by pressing
the fan button (high, medium, or low speed choices). The
fan(s) is capable of operation when unit mode is set on either cooling, heating, or auto mode. When the fan(s) is operating in medium or high speed and the unit is equipped
with the power ventilation kit, the ventilation fan will operate to provide fresh air. If the mode is set to the AUTO
position, then the fan will operate with the outdoor unit
compressor.
Cooling mode operation
When the room thermostat senses a demand for cooling,
the fan coil relay board is energized. The indoor fan(s) will
start at the selected speed (if it is not already operating).
The internal condensate pump (if so equipped) runs when
the unit is in cooling mode. As long as the condensate float
switch and freeze protection thermostat are closed, the cooling relays in the fan coil unit will close. This energizes the
compressor and outdoor fan in the outdoor unit.
The compressor will continue to operate until the room
thermostat is satisfied. When the cooling demand is satisfied, the compressor and outdoor fan will stop. If the outdoor unit is equipped with accessory Time Guardt device,
the unit will not allow a new call for cooling for 5 minutes.
If the system is in the AUTO position, the indoor fan will
stop with the compressor. If the unit has the accessory ventilation kit, the ventilation fan will operate whenever the indoor fan is set for medium or high speed.
System safeties — The system is equipped with the following safety devices to protect system components:
A. Condensate float switch (40QA units equipped with accessory condensate pump, cooling cycle only) — If the
level of condensate in the drain pan rises too high, the
condensate float switch will turn off the compressor and
outdoor fan until the condensate level returns to normal. The indoor fan will continue to run.
B. Outdoor Unit Safeties — These units are protected by
the following devices:
• high-pressure switch
• low-pressure switch (condensing units only)
• compressor internal overloads
• outdoor-fan motor internal overload
NOTE: Outdoor units with scroll compressors are also
protected by a high discharge gas temperature sensor
and a 2-minute timer to prevent possible reverse rotation of the compressor.
Should any of these devices trip after the compressor is
energized, the Cycle-LOC™ protection device will lock out
the outdoor unit (turn it off) to prevent cycling on a safety
device.
Cooling only thermostats — These thermostats are primarily for cooling applications, but can be used when both
cooling and heating set points are required. When set in
AUTO mode the space conditions are maintained by calling for either cooling or heating and maintaining at least a
2 degree differential between them. Indoor fan will operate
in all instances either in auto mode or in a pre-selected
manual mode. Automatic mode operation is as follows:
Auto Cooling mode:
Y
contact will be closed.
H1 contact open.
Auto Heating mode:
Y contact open
H1 contact will be closed.
Other thermostat operating features include the following:
• Center (orange) LED is for AUX heat.
• Right-hand (red) LED indicates a fault — compressor lockout when wired.
• Filter indicator on display screen becomes activated at
250 hrs of run time. To reset, hold fan button in for
5 seconds.
• Terminal block RSI, RS2, RS+V can be used for a remote indoor sensor so that the thermostat can be located
elsewhere (secure room).
