2. Summary of air handler IMPORTANT The iFLOW hydronic air handlers are designed to deliver the highest performance rating of any air handler regardless of the hot water A field fabricated auxiliary drain pan with a drain pipe connection is source. -
Page 4: Product Description
All air handlers require a field supplied single speed or 3-speed pump, galvanized steel. The inside of the cabinet is fully insulated with ½” to be controlled by the iFLOW circulator control. This the speed of the polyethylene sheets. This prevents moisture and mold growth, as well pump increases or decreases depending on the information provided as unwanted heat loss due to an R-Value. -

Recommended Clearances: Be sure to provide a minimum of 24” clearance to the front panel of the iFLOW air handler. 0” clearance is allowed for all other sides of the cabinet and for the first 36” of ductwork. Ensure adequate clearance is left for the installation of ductwork, plumbing, and electrical connections. -

Page 12: A/C Evaporator Coil Freeze Protection And The Importance Of Wiring The A/C Compressor To The Proper And Dedicated A/C Connector On The Iflow Pcb
(see figure D). If the 24V signal for the A/C compressor is connected to the thermostat connection on the iFLOW PCB, the 24V signal will come from the thermostat and there is no way for the iFLOW to interrupt the compressor, thus you will have NO A/C FREEZE PROTECTION. - Page 13 Temperature sensor varies by model but is generally located near the top center of the PCB. Please consult the PCB schematic in the installation manual for details. If steps 1 & 2 are followed, the iFLOW delivers A/C evaporator and hydronic coil freeze protection. iFLOW HVAC INC.
