Installing Units In Parallel - Heatworks 1 Manual

CAUTION: Serious damage to your Heatworks MODEL 1
can occur if all air is not purged from the water lines and
MODEL 1, any time air might be introduced into your
home water system.
7) Carefully inspect all connections and unions for leaks.
HEATWORKS RECOMMENDS: Since this product does
not use a storage tank, the use of a temperature
pressure relief valve (T&P) is not required for most
installations. However, a T&P valve may be required to
meet plumbing codes in your area.
CAUTION: The maximum recommended operating water
pressure for the Heatworks MODEL 1 is 100 PSI. Consult
your licensed plumber for specific information regarding
your water pressure.

INSTALLING UNITS IN PARALLEL

When installing multiple MODEL 1 units in the same
location with the purpose of having them support the
same hot water demand, please refer to the diagram to
the right.
In this installation configuration the cold water supply
line is split into two dedicated water lines, one line for
each MODEL 1 unit. The hot water lines then converge so
the outlet of each MODEL 1 unit supplies one hot water
line.
CAUTION: Breaker must remain off until installation is complete.
