3. Quick Connect Multi System Installation
• The Quick Connect Multi System allows the installation of two units together utilizing only the Quick
Connect Cord.
Typical Plumbing
* When connecting two units, disconnect
the remote controller connector from the
other unit.
Note: Connect the remote
controller to only one
of the units.
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.
Distance at center:
406 - 812mm (16-32").
Distance on sides
50 - 450mm
(2-18").
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.
Size the piping to allow for the maximum
flow rates of the units.

The Quick Connect Cord is 2m (6'). long. Install the units 50 - 450mm (2-18") 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).
