3-Way End of Cylce Valve
When piping the 3-Way End of Cycle valve, refer to label to
determine the direction of flow. The valve should be installed
so that there is a 2" (51mm) minimum clearance to remove the
actuator from the valve body. Provide unions for removal of
unit coil and/or control valve as a future service consideration.
Hot water connections may be same end as cooling coil
connections, but are recommended to be opposite end to
facilitate piping.
When using MicroTech® controls, they must be opposite end.
The End of Cycle valve accessory must be field installed on the
unit for which it was selected.
