Transcription

1 VARIABLE REFRIGERANT FLOW SYSTEMS VRF VMDB Concealed Medium Static Ducted Indoor Models - 60HZ PRODUCT ECIFICATIONS Bulletin No March 2018 Slim, compact design for limited space requirements. Installs out of sight between the drop ceiling and ceiling slab with ducted distribution to the indoor space. CONTENTS Blower Data Cooling Capacity Dimensions Heating Capacity Installation Clearances Model Number Identification Sound Data Specifications APPROVALS Units are ETL certified for the U.S. and Canada. WARRANTY Components - Limited ten years for qualifying installations. See Warranty Certificate for details. FEATURES Pre-Heat Function - Delays the operation of the fan until the indoor coil has reached a pre-determined temperature which prevents the discharge of cold air while the system is operating in the heating mode. LED Readout/Infrared Receiver Panel - Mounted on unit (may be remotely located). LEDs display unit operation status, and codes for maintenance and servicing. Infrared receiver for use with a wireless remote control (not furnished). Auto Addressing (Heat Pump Systems Only) - An optional wireless remote control (not furnished) can be used to inquire and modify each indoor unit s address. Auto Restart - Automatically restores the previous function setting if power is interrupted. Built-In Condensate Pump - 28 inch lift. Duct Connections - Return air connections can be made horizontally or from the bottom of the unit with interchangable panel. Electronic Expansion Valve - Assures optimal performance throughout the application range. Flare Connections - Equipped with liquid and gas flare fittings for quick and secure piping. Four-Stage Fan Speed (Standard Efficiency PSC Motor) - Fan functions at four levels: low, medium, high and super-high. Super-high speed is available with simple wiring change on main control board. Three-Stage Fan Speed (High Efficiency DC Motor) - Fan functions at three levels: low, medium, high. Air Filter - Cleanable air filter is furnished as standard.
