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. long. Install the units 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 dierence in pipe length
between the two units).

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.
• 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.
