A PERFECT BALANCE BETWEEN BUDGET
LIMITS, ENERGY SAVINGS AND COMFORT
The 40MBFQ series ductless system 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 can be mounted on the floor, against the wall on all the
sizes 12-58 and mounted on the ceiling on the sizes 18-58. This
selection of fan coils permits 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.

models may differ slightly.

The ideal compliment to your ducted system when it is impractical or
prohibitively expensive to use ductwork.
The 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.
Specifications subject to change without notice.
LOW SOUND LEVELS
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.
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 outdoor units can be installed
close to an outside wall, coils are protected from vandals and severe
weather.
FAST INSTALLATION
This compact ductless system is simple to install. A mounting bracket
is standard with the indoor units and only wire and piping need to be
run between the 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 ductless systems the equipment of
choice, especially in retrofit situations.
SIMPLE SERVICING AND MAINTENANCE
Removing the top panel on the outdoor units provides immediate
access to the control compartment, providing a service technician
access to check the unit’s 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.
BUILT-IN RELIABILITY
Ductless system indoor and outdoor units are designed to provide
years of trouble-free operation.
The 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 starts 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 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 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.
On all indoor units, service and maintenance expense is reduced due
to easy-to-use cleanable filters. In addition, these console systems
have extensive self-diagnostics to assist in troubleshooting.
ACCESSORIES
Customizing these ductless systems to your application is easily
accomplished.
Adding a condensate pump accessory to the console fan coil
provides installation flexibility.

Condensate PumpsA
On the console 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 an adequate drain line pitch cannot
be provided, or when the condensate must move up to exit.
