FEATURES / BENEFITS
A PERFECT BALANCE BETWEEN
BUDGET LIMITS, ENERGY SAVINGS AND
COMFORT.
The 40MBF/38MAQ 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 floor, against the wall. 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
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.
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
38MAQ/40MB*F 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 floor
console systems have extensive self- diagnostics to assist in
troubleshooting.
BUILT- IN RELIABILITY
Ductless split system indoor and outdoor units are designed to
provide years of trouble-free operation.
The floor console 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.
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 floor console 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 floor console fan coil
provides installation flexibility.

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.
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. 4.
Unit location - Select a location which will provide the best air
circulation for the room.
These units should be positioned on the floor, against 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.
UNIT MOUNTING (OUTDOOR)
Refer to unit Installation Instructions for further details.
Unit leveling - For reliable operation, units should be level in all
planes.
Clearance - Minimum clearance, as shown in Fig. 5, must be
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.
MOUNTING TEMPLATE
Refer to unit Installation Instructions for further details.
The fan coil units are furnished with mounting to mark the location
of the wiring, and refrigeration line hole locations.
SUPPORT
Adequat e support must be provided to support the weight of all fan
coils. Refer to the Physical Data section for fan coil weights, and the
base unit dimensiona l drawings for the location of mounting brackets.

DRAIN CONNECTIONS
Install drains to meet local sanitation codes. If adequate gravity
drainage cannot be provided, unit should be equipped with
accessory condensate pump. Floor console fan coil unit condensate
pumps have a maximum lift of 10’ (3.05 m) for 9k and 12k units.
See physical dimension tables for drain sizes.
NOTE: Floor console fan coil units have internal condensate
traps. A trap is not required.
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.
