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 2m (6'). long. Install the units 50 - 475mm (2-19") 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.

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.
