INDUSTRY LEADING

FEATURES / BENEFITS

A PERFECT BALANCE BETWEEN

BUDGET LIMITS, ENERGY SAVINGS AND

COMFORT.

The 40MBDQ series ducted slim ductless 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 in the ceiling. 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 Historical renovations or any application where

preserving the look of the original structure is essential.

These compact indoor fan coil units take up very little space above

the ceiling. 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 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. Ducted style ductless system indoor and outdoor units are designed to provide years of trouble−free operation.

APPLICATION DATA WIRING UNIT SELECTION Select equipment to either match or that can handle slightly less than the anticipated peak load. This provides better humidity control, fewer unit cycles, and less part−load operation. For units used in spaces with high sensible loads, base equipment selection on unit sensible load, not on a total anticipated load. Adjust for anticipated room wet bulb temperature to avoid undersizing equipment.

CONTROL SYSTEM WIRED REMOTE CONTROL The indoor unit is equipped with a microprocessor control to perform two functions: 1. Provide safety for the system 2. Control the system and provide optimum levels of comfort and efficiency The main microprocessor is located on the control board of the fan coil unit (outdoor units have a microprocessor also) with thermistors located in the fan coil air inlet and on the indoor coil. Heat pump units have a thermistor on the outdoor coil.

EXTERNAL STATIC PRESSURE Using the KSACN0501AAA Wired Controller, the external static pressure can: S Be manually changed to the fan curves SP2, SP3, SP4. S Choose the Automatic Airflow “AF” adjustment function which will automatically identify the static pressure and regulate the amount of airflow. Follow instructions to configure: 1. Make sure the test run is done with a dry coil. If the coil is not dry, run the unit for 2 hours in FAN ONLY mode to dry the coil. 2.
