14GUIDE SPECIFICATIONSINDOOR WALL--MOUNTED FLOOR CONSOLE DUCTLESS UNITSSize Range: 3/4 to 1 Ton Nominal Cooling and Heating CapacityCarrier Model Number: 40MB*FPART 1 -- GENERAL1.01 System DescriptionIndoor, wall--mounted floor console, direct--expansion fan coils arematched with cooling only or heat pump outdoor unit .1.02 Agency ListingsUnit shall be rated per AHRI Standards 210/240 and listed in theAHRI directory as a matched system.1.03 Delivery, Storage, And HandlingUnits shall be stored and handled per unit manufacturer’srecommendations.1.04 Warranty (For Inclusion By SpecifyingEngineer)PART 2 -- PRODUCTS2.01 EquipmentA. General:Indoor, direct--expansion, floor--mounted fan coil. Unit shall becomplete with cooling/heating coil, fan, fan motor, pipingconnectors, electrical controls, microprocessor control system, andintegral temperature sensing. Unit shall be furnished with integralmounting bracket and mounting hardware.B. Unit Cabinet:Cabinet discharge and inlet grilles shall be attractively styled,high--impact polystyrene. Cabinet shall be fully insulated forimproved thermal and acoustic performance.C. Fans:1. Fan shall be tangential direct--drive blower type with airintake in the center of the unit and discharge at the top andbottom front. Automatic, motor--driven vertical air sweepshall be provided standard.2. Air sweep operation shall be user selectable. The verticalsweep may be adjusted (using the remote control) and thehorizontal air direction may be set manually.D. Coil:Coil shall be copper tube with aluminum fins and galvanized steeltube sheets. Fins shall be bonded to the tubes by mechanicalexpansion and specially blue hydrophilic pre--coated for enhancedwet--ability. A drip pan under the coil shall have a drain connectionfor hose attachment to remove condensate. Condensate pan shallhave internal trap.E. Motors:Motors shall be open drip--proof, permanently lubricated ballbearing with inherent overload protection. Fan motors shall be4--speed.F. Controls:Controls shall consist of a microprocessor--based control systemwhich shall control space temperature, determine optimum fanspeed, and run self diagnostics. The temperature control rangeshall be from 62_F to 86_F (17_C to 30_C) in increments of 1_For 1_C, and have 46_F Heating Mode (Heating Setback). Thewireless remote controller shall have the ability to act as thetemperature sensing location for room comfort.The unit shall have the following functions as a minimum:1. An automatic restart after power failure at the sameoperating conditions as at failure.2. A timer function to provide a minimum 24--hour timercycle for system Auto Start/Stop.3. Temperature--sensing controls shall sense return airtemperature.4. Indoor coil freeze protection.5. Wireless infrared remote control to enter set points andoperating conditions.6. Automatic air sweep control to provide on or off activationof air sweep louvers.7. Dehumidification mode shall provide increased latentremoval capability by modulating system operation and setpoint temperature.8. Fan--only operation to provide room air circulation when nocooling is required.9. Diagnostics shall provide continuous checks of unitoperation and warn of possible malfunctions. Errormessages shall be displayed at the unit.10. Fan speed control shall be user--selectable: high, medium,low, or microprocessor controlled automatic operationduring all operating modes.11. Automatic heating--to--cooling changeover in heat pumpmode. Control shall include deadband to prevent rapidmode cycling between heating and cooling.12. Indoor coil high temperature protection shall be provided todetect excessive indoor discharge temperature when unit isin heat pump mode.G. Filters:Unit shall have filter track with factory--supplied cleanable filters.H. Electrical Requirements:Indoor fan motor to operate on 208--230V as specified. Power issupplied from the outdoor unit.I. Operating Characteristics:The 40MB*F system shall have a minimum SEER (SeasonalEnergy Efficiency Ratio) and HSPF at AHRI conditions, as listedon the specifications table.J. Refrigerant Lines:All units should have refrigerant lines that can be oriented toconnect from the left, right or back of unit. Both refrigerant linesneed to be insulated.K. Special Features (Field Installed):1. Condensate Pump:-- The condensate pump shall remove condensate from thedrain pan when gravity drainage cannot be used. Pumpshall be designed for quiet operation. Pump shall consist oftwo parts: an internal reservoir/sensor assembly, and aremote sound--shielded pump assembly. A liquid levelsensor in the reservoir shall stop cooling operation if theliquid level in the reservoir is unacceptable. |
