MODULAR STANDARD ECM
IR HANDLERS
5493749-BTG-B-0619

DESCRIPTION

This unique modular system allows the flexibility to handle any application. These versatile ME blowers may be used for upflow, downflow, or horizontal left or right applications. They may be combined with cased coils to function as a cooling only unit or with a heat pump including electric heat for 1 and 3 phase applications. The ME blower and 6HK electric heat kits can be used as stand alone electric furnaces. Using Standard ECM motors, system matches provide higher SEER/HSPF ratings than standard blower models at attractive price points.

FEATURES

COMMON ME AIR HANDLER AND MATCH-UP CM COIL FEATURES
Rigid Case Construction - An interior endoskeleton for
structural support, smooth sides, and locks in insulation. Powder-painted - G30 galvanized steel case provide a coated
edge that resists corrosion and rust creep. Quality Construction - Structural components are made of
Aluminum or G90 galvanized steel to prevent corrosion. Improved Insulation Design - Single piece with no external
screws to reduce thermal transmission paths to prevent sweating. Foil faced insulation for ease of cleaning.
Case Depth - These models have 20.5” casing which provide ease of attic access and tight applications.
ME AIR HANDLERS Factory Sealed - Achieves 2% or less total airflow leakage rate
at duct leakage test conditions in positive and negative pressure for system airflow verification.
Electric Heat Kits - 6HK series of field installed electric heat kits are available for installation-friendly and easy service applications.
Blowers - All models use direct-drive, standard ECM motors. CM COILS
MaxAlloy
lasting performance, efficiency, and reliability. Thermostatic Expansion Valve - The TXV is installed using
Chatleff mechanical fittings and is easy to install on any MaxAlloy coil without brazing to create an appropriate system match. Some models are available with a factory installed TXV.
Thermoset Drain Pan - Low retention and positive slope for drainage to reduce potential mold or contaminants.
Accessories - A full line of matching accessories available for use with the blower and coils to provide for any type of application.
TM
Coil - Long life aluminum coils built to deliver
dditional rating information can be found at
