controller to only one of
the units.
System Diagram
The Quick Connect Cord is 2m long. Install the units to ensure the cord will be able to reach between
the units. (See Typical Plumbing diagram).
(If the distance between the two units is too great, not only will the cord not be able to reach, but the water
temperature may also become unstable because of the difference in pipe length between the two units).
• Insulate the hot water piping to prevent heat loss. insulation and apply heating materials to the cold water
supply piping to prevent heat loss and freezing of pipes when exposed to excessively cold temperatures.
