Leave enough clearance around the plumbing to
apply insulation. It will be necessary to add
bends to the piping to ensure that this clearance
is available.

Quick Connect Multi System Installation
• The Quick Connect Multi System allows the installation of two units together utilizing only the Quick
Connect Cord-2.
Typical Plumbing
The Quick Connect Cord-2 is 2m long. Install the units 50 - 457mm apart from each other 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).
* When connecting 2 devices, use only a
single remote controller.
Note: Connect the remote
controller to only one
of the devices.
System Diagram
• Insulate the hot water piping to prevent heat loss. Insulate and apply heating materials to the
cold water supply piping to prevent heat loss and freezing of pipes when exposed to excessively
cold temperatures.
