Product Data 38/40BN Series Duct-Free Split Systems Cooling Only and Heat Pumps for High-Wall Applications 11/2 to 3 Nominal Tons The Ideal Complement to Your Ducted System When It Is Impractical or Prohibitively Expensive to Use Ductwork Features/Benefits An inexpensive and creative solution to design problems INDOOR UNIT OUTDOOR UNIT Copyright 2004 Carrier Corporation The 38/40BN series duct-free split systems are a matched combination of an outdoor condensing unit and an indoor fan coil units conn
The 38/40BN duct-free split systems offer the solution of choice. The compressor is outdoors, linked by refrigerant lines to an indoor fan coil located directly in the room it will heat or cool. These systems have minimal impact on the existing structure, and the design and interior of the conditioned space is not compromised by bulky ductwork. Because of these features, this duct-free split system can be installed in places where conventional ducted cooling simply cannot go.
Features/Benefits (cont) Economical operation The duct-free split system design allows individual room heating or cooling only where 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. Features like the rifled copper tube with louvered aluminum plate fin coil provide maximum heat transfer.

Application data Unit selection FAN COIL UNITS Select equipment to either match or be slightly less than 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 total anticipated load. Adjust for anticipated room wet bulb temperature to avoid undersizing equipment.

Controls The Duct Free System can be set up and operated from the remote control (provided). If the remote is misplaced, the system can be operated from the “Auto” setting on the unit. If temperature of room air is lower than set point, the system will operate in Heating mode. If temperature of room air is higher than set point, the system will operate in Cooling mode.
Controls (cont) NOTE: If placing the air deflector in a fixed position is chosen, the deflector stops at the angle in which it was located when the ON/OFF button was pressed. Programming time periods — The duct free system can be programmed to operate at desired levels. Be sure to set the clock before programming the system. NOTE: If unit is operating in Dehumidification mode the fan will only operate in Low speed and cannot be changed.
