INDUSTRY LEADING
FEATURES / BENEFITS
A PERFECT BALANCE BETWEEN
BUDGET LIMITS, ENERGY SAVINGS AND
COMFORT.
The MK 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 under the ceiling or on the wall, near 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
• When changes in the load cannot be handled by the
existing system.
• 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 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 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 24AHA4/25HHA4/124ANS/224ANS unit is the
right choice: The advanced, horizontal blow -through 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 24AHA4/25HHA4/124ANS/224ANS 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 MK 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 through
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 -access cleanable filters. In addition, these ductless
systems have extensive self -diagnostics to assist in
troubleshooting.
Ductless split system indoor and outdoor units are designed to
provide years of trouble -free operation.
The indoor units include protection against freeze-up and high
evaporator temperatures on heat pumps.
The condensing units and heat pumps are also protected. There is a
3-minute time delay before the compressor will re -start. An
oversized accumulator (Heat Pump), high pressure switches (or
liquid line pressure switch on the heat pump), and compressor
internal overload protection will ensure a reliable system that is
ideal for light commercial applications.
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 ductless units have microprocessor -based controls to provided
the ultimate in comfort and efficiency. The user friendly wireless
remote control provides the interface between user and the unit.
FLEXIBILITY
A variety of accessories simplify the installation process and help
meet system requirements and weather conditions. See Table 2 on
page 4 for available accessories.

On ductless fan coils, the condensate pump has a lift capability of
12 ft (3.6 m) on the discharge side with the pump mounted in the
fan coil or 6 ft (1.8 m) on the suction side if the pump is remote
mounted. The pump is recommended when adequate drain line
pitch cannot be provided, or when the condensate must move up to
exit.
Wired Remote Controller
For applications where the use of wireless remote control is not
desired, the MK units can be controlled by means of a wired
wall -mounted control with an LCD display.

OUTDOOR UNIT ACCESSORIES
Low Ambient Kit
Stacking Kit
A fan -speed control device activated by a temperature sensor,
designed to control condenser fan motor speed in response to the
saturated condensing temperatures down to -20GF (-28.9GC), it
maintains condensing temperature at -100F ± 1OF (37.8C ± 6C)
A MotorMaster Low -Ambient Controller or Low -Ambient
Pressure Switch must be used when cooling operation is used at
outdoor temperatures below 55GF (12.8GC), and can be used on all
outdoor units without changing the outdoor fan motor.
Winter Start Control
Stacking Kits allow stacking of equally sized
smaller units to be stacked on top of larger units.
NOTE: THIS KIT CANNOT BE USED
PUMPS.
The Winter Start Control is a 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 a;
low ambient temperatures. This relay is recommended on cooling
only systems that have the accessory Low Ambient Kit.
Isolation Relay MOUNTING FEET(6)
BOLTED TO
MOUNTING PAD
The Isolation Relay must be used when Low Ambient Kit is used
with heat pumps to ensure the pressure switch is bypassed when
unit is running in heat pump mode.
Liquid Line Solenoid Valve
The Liquid Line Solenoid Valve is an electrically operated shut-off
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.
Crankcase Heater
The Crankcase Heater is available for units with scroll compressors
and clamps onto the compressor oil sump. It is recommended for
low ambient applications. The Crankcase Heater is standard on
sizes 30 and 36 Heat Pump.
Wind Baffles
The Wind Baffle is a sheet metal shield used to provide improved
unit operation during high winds and is recommended whenever
the low ambient accessory is used.

APPLICATION DATA
UNIT SELECTION
Table 12—Heating Operating Range
The horizontal units are available as cooling only and heat pumps.
For most applications, the cooling load dictates the size selection.
Select equipment to either match or be slightly less than anticipated
peak load. This provides better humidity control, fewer unit cycles,
and better low load performance.
For units used in spaces with high sensible loads, base equipment
selection on unit sensible load, not on total anticipated load to
avoid oversizing the equipment.
UNIT MOUNTING (INDOOR)
Unit leveling - For reliable operation, units should be level in all
planes.
Clearance - Provide adequate clearance for airflow (see Fig. 7).
Unit location - Select a location which will provide the best air
circulation for the room.
The Under Ceiling 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 makes piping easier,
however units can also be mounted away from a wall if desired. If
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 (4.6 m)
to prevent dumping of cold air and drafts.
Support - The structure must provide adequate support for the weight
of the fan coil. Refer to the Physical Data section for fan coil weights.
Mounting Template - The fan coil units are furnished with
cardboard mounting templates to mark the hole locations for
wiring and refrigerant lines.
UNIT MOUNTING (OUTDOOR)
Unit leveling - For reliable operation, units should be level in all
planes.
Clearance - Minimum clearance, as shown in Fig. 10, 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. If the unit is exposed to strong winds it
is recommended that a wind baffle accessory be used.
A location which can bear the weight of outdoor unit and where
the outdoor unit can be mounted in a level position.

Low Ambient Operation
Both the cooling only and heat pumps operate to cool down to
55°F (12.8°C). When equipped with a Low Ambient Controller,
the unit operates down to -20°F (-28.9°C).
For proper operation of colling only units, a Winter Start Kit), a
Crankcase Heater (prevents refrigerant migration during
compressor -off cycle), and a Wind Baffle should also be installed.
On heat pumps, a Winter Start Kit will not be required. An
Isolation Relay, to bypass the Low Ambient Controller when unit
is in heating mode, is required.
Metering Devices
The metering device(s) for these systems is a type B accurator. The
cooling accurator is installed with the indoor unit, while the
heating accurator is installed with the outdoor unit. One Accurator
is required for the cooling only system and two are required for the
heat pump systems. Refer to Table 13 for the accurator size.

DRAIN CONNECTIONS
When the unit is installed close to an outside wall, a downward
sloped condensate line can be used to dispose of the water (do not
trap condensate line). If this is not feasible, an accessory
condensate pump that can be installed inside the unit is available.
When using a condensate pump, the drain pipe can be routed
through the top of the unit, if desired.
Install drains to meet local sanitation codes. If adequate gravity
drainage cannot be provided, unit should be equipped with
accessory condensate pump.

CONTROL SYSTEM
REFRIGERANT LINES
General refrifferant line sizing
1. Refrigerant lines can access the Under Ceiling unit from
either the top -right or rear -right when facing the unit.
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.
(12.7mm) 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.
NOTE: Since the same outdoor unit can be matched with
different types of indoor units, it may not have enough
refrigerant charge. Refer to the Physical Data tables to
determine if additional charge is required.
Long Line Applications
The minimum length between the indoor and outdoor units is 10 ft.
(3m). Refer to the following table for the maximum lengths
allowed.

* Maximum actual length not to exceed 200 ft (61 m)
Total equivalent length accounts for losses due to elbows or fitting.
See the Long Line Guideline for details.
The ductless unit is equipped with a microprocessor controls to
operate the system and provide optimum levels of comfort and
operating efficiency.
The main microprocessor 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 the system operation and
control the operating mode. To change the settings or the modes of
operation, use the factory supplied wireless remote control or
accessory wired controller.
The ductless unit has 5 operating modes:
• Fan Only
• Auto (heat pump models only)
• Heating (heat pump models only)
• Cooling
• Dehumidification (Dry)
FAN ONLY - In the Fan Only mode, the system filters and
circulates the room air without changing the room air temperature.
AUTO - In Auto mode, the system will automatically select one of
the following operating modes: cooling, heating or fan only based
on the difference between the room temperature and the set point
temperature.
HEATING - In the Heating mode, the system heats and filters
room air.
COOLING - In the Cooling mode, the system cools, dries and
filters room air.
DEHUMIDIFICATION (DRY) - in Dehumidification (Dry)
mode, the system dries, filters and slightly cools room temperature.
This mode does not take the place of a dehumidifier.
In addition to the above modes that are selected by using the
remote control. The unit can run in two other modes selected by
the manual button:
• EMERGENCY RUN
• TEST MODE
EMERGENCY mode - is used when the remote control is
misplaced or the batteries in the remote control have expired.
Pushing the manual button under the front cover will put the unit
in Auto mode with a predetermined set point (73.4°F/ 23°C).
TEST mode - is used when a technician needs to diagnose the
unit for a malfunction. The unit can be set into TEST mode using
the remote control. It will run regardless of the set point.
The microprocessor controls offer additional comfort and economy
features like SLEEP mode, TIMER and AUTO SWEEP. Refer to
the Owner's Manual for additional details on these features.
USER INTERFACE
The units come standard with a wireless remote control. The
wireless remote has a range of 25 ft (8 m) when pointed toward the
unit.
For some applications (commercial), a wired remote may be more
desirable. A wired remote control is offered as an accessory.
