INDUSTRY LEADING
FEATURES / BENEFITS
A PERFECT BALANCE BETWEEN BUDGET LIMITS, ENERGY SAVINGS AND COMFORT.
The 38/40MAQ 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 wall, near the ceiling. This selection of fan coils permits creative solutions to design problems such as:
S Addons 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 38/40MAQ 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 drawthru 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 easyto- use cleanable filters. In addition, these high wall systems have extensive selfdiagnostics to assist in troubleshooting.
BUILTIN RELIABILITY
Ductless split system indoor and outdoor units are designed to provide years of troublefree operation.
The high wall indoor units include protection against freezeup 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 overcurrent 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, yearround 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 supplyair 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.
EASYTO- USE CONTROLS
The highwall units have microprocessorbased 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 high wall fan coil provides installation flexibility.

Fig. 1 – Condensate Pump Accessory
On high wall 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.
NOTE: An external 115v power source will be required to run the pump on unit sizes 9k and 12k.
OUTDOOR UNITS
Crankcase Heater
Standard on all unit sizes. Heater clamps around compressor oil stump.
