Quick Connect Multi System Installation
• The Quick Connect Multi System allows the installation of two units together utilizing only the Quick
Connect Cord.
The Quick Connect Cord is 6 ft.(2m) long. Install the units 3-18" (75-457mm) 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).

Make this distance as
short as possible.
The hot water temperature
will become unstable as
the pipe length increases.
• 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.

Isolation Valve*
* Isolation valves are
necessary for flushing
the Heat Exchanger.
They allow for
easy flushing of
the system.
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.
* When connecting two units, use only a
single remote controller.

The backflow preventer should be placed
upstream of the cold water branch.
Note: Connect the remote
controller to only one
of the units.
Units must be same
model in order to
quick connect.
Size the piping to allow for the
maximum flow rates of the units.
