FEATURES / BENEFITS

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 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 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.

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 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 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 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 systems to your application is easily
accomplished.

Adding a condensate pump accessory to the floor console fan coil
provides installation flexibility.

INDOOR UNITS

On the floor 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.
