 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

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).

* 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.

Make this distance as short as possible.
