Fig. 3-2 Transition for horizontal left orientation
3. If the coil is used in connection with an upflow furnace in horizontal left orientation, a sheet metal transition can be installed
between the furnace supply air outlet and the evaporator coil supply air inlet to create clearance between coil lineset and
furnace flue outlet for A-cabinet non-condensing furnaces and for all cabinet size condensing furnaces. See Fig. 3-2
For A-cabinet non-condensing furnaces, a 6" transition is needed.
For all cabinet size condensing furnaces, a 6.5" transition is needed.
If space is a constraint, the lines/flue interference can be removed by rotating the coil such that the line set is facing the opposite
direction and air flow through the bottom of the A-coil, thus optimizing airflow.
When using a gas furnace for heating, ensure that the heat exchanger temperature does not exceed 200 ℉.
Exceeding this temperature may cause the refrigerant leak sensor to malfunction, which can lead to a hazardous
situation.
3.4 Installation of Refrigerant Sensor
The wire of the refrigerant sensor must be connected to the leak mitigation control kit. For specific operation instructions, please
refer to the Wiring diagrams and explanatory label of the leak mitigation control kit.
