INDUSTRY LEADING
FEATURES / BENEFITS
A PERFECT BALANCE BETWEEN
BUDGET LIMITS, ENERGY SAVINGS AND
COMFORT.
The 38/40MAQ series ductless split systems are a matched
combination of an outdoor condensing unit and an indoor fan coil
unit connected only by refrigerant tubing and wires.
The fan coil is mounted on the wall, near the ceiling. This
selection of fan coils permits creative solutions to design problems
such as:
S
Add- ons to current space (an office or family room
addition)
S
Special space requirements
S
When changes in the load cannot be handled by the
existing system.
S
When adding air conditioning to spaces that are heated
by hydronic or electric heat and have no ductwork.
S
Historical renovations or any application where
preserving the look of the original structure is essential.
The ideal compliment to your ducted system when it is
impractical or prohibitively expensive to use ductwork.
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 low sound levels.
LOW SOUND LEVELS
BUILT- IN RELIABILITY
When noise is a concern, the ductless split systems are the answer.
The indoor units are whisper quiet. 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.
When sound ordinances and proximity to neighbors demand quiet
operation, the 38MAQ unit is the right choice: The advanced,
horizontal airflow design distributes air more evenly over the coil.
Ductless 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 evaporator temperatures on heat pumps.
The condensing units on heat pumps are protected by a three
minute time delay before the compressor will start the over- current
protection and the high temperature protection.
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 38MAQ units can
be installed close to an outside wall, coils are protected from
vandals and severe weather.
FAST INSTALLATION
This compact ductless split system is simple to install. A
mounting bracket is standard with the indoor units and only wire
and piping need to be run between indoor and outdoor units.
These units are fast and easy to install ensuring minimal
disruption to customers in the home or workplace. This makes the
38/40MAQ ductless split systems the equipment of choice,
especially in retrofit situations.
SIMPLE SERVICING AND
MAINTENANCE
Removing the top panel on outdoor units provides immediate
access to the control compartment, providing a service technician
access to check unit operation. In addition, the draw- thru design of
the outdoor section means that dirt accumulates on the outside
surface of the coil. Coils can be cleaned quickly from the inside
using a pressure hose and detergent.
On all indoor units, service and maintenance expense is reduced
due to easy- to- use cleanable filters. In addition, these high wall
systems have extensive self- diagnostics to assist in
troubleshooting.
INDIVIDUAL ROOM COMFORT
Maximum comfort is provided because each space can be
controlled individually based on usage pattern. The air sweep
feature provided permits optimal room air mixing to eliminate hot
and cold spots for occupant comfort. In addition, year- round
comfort can be provided with heat pumps.
ECONOMICAL OPERATION
The ductless split system design allows individual room heating or
cooling when 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.
EASY- TO- USE CONTROLS
The high- wall units have microprocessor- based controls to
provide the ultimate in comfort and efficiency. The user friendly
wireless remote control provides the interface between user and
the unit.
ACCESSORIES
Customizing these ductless split systems to your application is
easily accomplished.
Adding a condensate pump accessory to the high wall fan coil
provides installation flexibility.

APPLICATION DATA
UNIT SELECTION
DRAIN CONNECTIONS
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.
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 maximum lift of 10’ (3.05 m) for 9k and 12k units
and 25’ (7.62 m) for 18k and 30k units.
See physical dimension tables for drain sizes.
NOTE: High wall fan coil units have internal condensate traps.
A trap is not required.
Drain connections may be routed through alternate locations on
most fan coils as shown in Fig. 4.
UNIT MOUNTING (INDOOR)
Refer to unit Installation Instructions for further details.
Unit leveling - For reliable operation, units should be level in all
planes.
Clearance - Provide adequate clearance for airflow as shown in
Fig. 2.
Unit location - Select a location which will provide the best air
circulation for the room.
These units should be positioned as high as possible on the wall for
best air circulation. The unit return and discharge should not be
obstructed by furniture, curtains, or anything which may cause unit
short cycling or air recirculation. Place the unit in the middle of the
selected wall (if possible). Use an outside wall, if available, to
make piping easier, and place the unit so it faces the normal
location of room occupants.

REFRIGERANT LINES
General refrigerant line sizing:
1. The 38MAQ units are shipped with a full charge of
R410A refrigerant. All charges, line sizing, and capacities
are based on runs of 25 ft (7.6 m). For runs over 25 ft (7.6
m), consult long- line section on this page for proper
charge adjustments.
2. Refrigerant lines should not be buried in the ground. If it is
necessary to bury the lines, not more than 36- in (914 mm)
should be buried. Provide a minimum 6- in (152 mm)
vertical rise to the service valves to prevent refrigerant
migration.
3. Both lines must be insulated. Use a minimum of 1/2- in.
(12.7 mm) 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.
Long Line Applications, 38MAQ Units:
1. No change in line sizing is required.
2. Add refrigerant per table below.

provided for airflow. The condensing units are designed for
free- blow application. Air inlets and outlets should not be
restricted.
Unit location - A location which is convenient to installation and
not exposed to strong wind.
A location which can bear the weight of outdoor unit and where
the outdoor unit can be mounted in a level position.
Do not install the indoor or outdoor units in a location with special
environmental conditions. For those applications, contact your
Carrier representative.

WIRING
Recommended Connection Method for Power and Communication Wiring (To minimize communication wiring interference)
Power Wiring:
The main power is supplied to the outdoor unit. The field supplied
connecting cable from the outdoor unit to indoor unit consists of
three (3) wires and provides the power for the indoor unit. Two
wires are high voltage AC power and one is a ground wire.
Consult your local building codes and the NEC (National
Electrical Code) or CEC (Canadian Electrical Code) for special
requirements.
All wires must be sized per NEC or CEC and local codes. Use
Electrical Data table MCA (minimum circuit amps) and MOCP
(maximum over current protection) to correctly size the wires and
the disconnect fuse or breakers respectively.
Per caution note, only copper conductors with a minimum 300 volt
rating and 2/64- inch thick insulation must be used.
Communication Wiring:
A separate shielded copper conductor only, with a minimum 300
volt rating and 2/64- inch thick insulation, must be used as the
communication wire from the outdoor unit to the indoor unit.
To minimize voltage drop, the factory recommended wire size is
14/3 stranded with a ground. In special cases where there is high
electrical interference, please use a separate shielded 16GA
stranded control wire.
Alternate Connection Method for Power and Communication
Wiring (May not prevent communication wiring interference)
The main power is supplied to the outdoor unit. The field
supplied connecting cable from the outdoor unit to indoor unit
consists of four (4) wires and provides the power and
communication signals for the indoor unit. Two conductors are for
power wiring (L1/L2, or L/N), one is a ground wire, and one is a
DC communication wire.
Consult your local building codes and the NEC (National
Electrical Code) or CEC (Canadian Electrical Code) for special
requirements. All power wires must be sized per NEC or CEC
and local codes. Use Electrical Data table MCA (minimum circuit
amps) and MOCP (maximum over current protection) to correctly
size the wires and the disconnect fuse or breakers respectively.
Per caution note, only copper conductors with a minimum 300 volt
rating and 2/64- inch thick insulation must be used.

from indoor unit to outdoor unit.
S Every wire must be connected firmly. Loose wiring
may cause terminal to overheat or result in unit
malfunction. A fire hazard may also exist. Therefore,
be sure all wiring is tightly connected.
S No wire should be allowed to touch refrigerant tubing,
compressor or any moving parts.
S Disconnecting means must be provided and shall be
located within sight and readily accessible from the air
conditioner.
S Connecting cable with conduit shall be routed through
hole in the conduit panel.
The main power is supplied to the outdoor unit. the field supplied
connecting cable from the outdoor unit to indoor unit consists of
four wires and provides the power for the indoor unit as well as the
communication signal between the outdoor unit and indoor unit.
Two wires are high voltage AC power (L1 and L2), one is a
ground wire, and one is a DC communication wire.
CONTROL SYSTEM
The 40MAQ unit is equipped with a microprocessor control to
perform two functions:
1. Provide safety for the system
2. Control the system and provide optimum levels of comfort
and efficiency
The main microprocessor is located on the control board of the
fan coil unit (outdoor units have a microprocessor too) with
thermistors located in the fan coil air inlet and on the indoor coil.
Heat pump units have a thermistor on the outdoor coil. These
thermistors monitor the system operation to maintain the unit
within acceptable parameters and control the operating mode.
