AFM Series Multi-Position Hydronic Heat Air Handlers
Features and Benefits
APPLICATION VERSATILITY
This unit is designed for use in upflow, downflow, horizontal left and horizontal right applications. Can be AHRI certified with most brands of air conditioners or heat pumps.
• A2L refrigerants require a Refrigerant Detection System (RDS) for compliance. In accordance to UL 60335 Refrigerant Detection Systems are factory-installed on A2L refrigerant ready air handlers.
• ETL listed for R22 and 410A. ETL listed for R454B and R32 with (RDS) Refrigerant Detection System.
120V Constant Torque ECM Motor (Hydronic Heat)
Constant torque ECM speeds and torques are controlled by embedded motor software and factory pre-programmed. Direct drive blowers circulate air quietly and efficiently. Air moving system is plated mounted to allow for easy removal and service.
LOW LEAKAGE CABINET
Less than 2% air leakage from cabinet when tested in accordance with ASHRAE standard 193. Unit must be installed according to Aspen installation instructions. Sturdy, short, galvanized steel cabinet with painted front panels. Cabinet fully insulated with 1/2” faced insulation to prevent sweating, to encapsulate glass fibers, and to provide excellent R-value. Stick pins ensure insulation remains in place. Units ship with disposable filter in filter rack.
BLOWER
Direct drive blowers circulate air quietly and efficiently. Motor speeds and torques programmed in the motor. Blowers mounted on rails so they can be easily removed for service.
ELECTRONIC CONTROL BOARD
Electronic circuit board provides 30 sec. ON/OFF blower time delay extracting more heat/cool from the coil. An electronic board controls the functioning of the system reducing moving parts. The board provides for various hot water supply source connections and the blower time delay to maximize heat/cool extraction. As an enhanced feature the pump circulates hot water every 6 hours to prevent water stagnation.
MODULAR HYDRONIC HEAT KITS
Air Handlers are available with either factory-installed circuit breakers or terminal blocks. Hydronic Coils come in 2, 3 and 4 row with the options of pump or no pump configurations. Freeze stat is standard, wired into circulating pump control circuit. Controls are accessible from the front for easy service. Electrical connections can be made from the top or left. Disconnect protrudes through the front panel for easy access. Fan time delay relay standard for increased efficiency. Heat kits are available with or without circulating pump and check valve. Units are provided with auxiliary relay for remote pump. Schrader ports are standard on water-out manifold, hose bib available as an option.
DX COIL
High efficiency rifled copper tubes/enhanced aluminum fins provide maximum heat transfer. All coils immersion tested at 500 psi then nitrogen pressurized and factory sealed for maximum reliability. Liquid-line Schrader allows preinstallation pressure testing. Available with either orifice or TXV metering device. Field-installable bolt-on TXVs are also available. Rugged, UV safe, GLP drain pan holds minimal condensate while eliminating the possibility of corrosion. Galvanized metal drain pan with bottom primary and secondary drain connections or alternate right side primary. All connections 3/4” FPT. Access door allows for coil cleaning.
WARRANTY
Five-year limited parts warranty with registration.
