FEATURES / BENEFITS
A PERFECT BALANCE BETWEEN
BUDGET LIMITS, ENERGY SAVINGS AND
COMFORT.
The 38/40MB*C 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 in- ceiling cassette fan coils are ideal for retrofit or
modernization projects where a false ceiling is available. This
selection of fan coils permits inexpensive and 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 38/40MB*C 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 cassette
systems have extensive self- diagnostics to assist in
troubleshooting.
FACTORY INSTALLED BASEPAN HEATER
BUILT- IN RELIABILITY
Ductless split system indoor and outdoor units are designed to
provide years of trouble-free operation.
The in- ceiling cassette 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 in- ceiling cassette has 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.
FACTORY INSTALLED CONDENSATE
PUMP
Customizing these ductless split systems to your application is
easily accomplished. The factory installed condensate pump on the
cassette fan coil unit provides installation flexibility.
