Wire entry into the unit should be made
through the knockout in the bottom of the
cover.
Cover End Cap must be removed to allow
installation and inspection of proper wiring.
(Verify correct installation in accordance with
diagram on page 2 of this manual prior to
wiring unit for proper operation).
Proper connectors should be chosen for the
wire/conduit selected.
Connect properly sized copper leads to the
terminal block as shown.
Connect the power circuits to L1 and L2 as
shown and the ground to GND. (For 120V
models connect the Neutral to L2/N on the
terminal block).
PRE-POWER CHECK:
Verify that all connections are secure.
Verify that an adequate ground has been
properly connected.
Verify that adequate sized breakers have
been properly connected. Remember that
breakers that are too large are more
dangerous that breakers that are too small.
Verify proper wire size has been used for
connection.
Check voltage at the terminal block for each
circuit.
THIS INSTALLATION MUST BE DONE BY A QUALIFIED AND LICENSED
CONTRACTOR. Refer to your local electric and plumbing codes for additional
information.

PERFORMANCE:
When evaluating the performance of the complete hybrid heating system, one must
consider not only the Seisco Supercharger but also the heating capability of the
tank. The following chart demonstrates the expected performance. The GPM* chart
below shows the flow rates for hot water deliverable at 115°F, based on the water
temperature in the tank, and the combined heating capacity of the primary heating
source PLUS the Supercharger. The performance chart demonstrates, as the water
temperature in the tank declines, the combined capacity to provide hot water flow
also declines but remains more than sufficient to provide that hot water needed to
allow for a tempered 105°F hot shower “Endlessly”.

SUPERCHARGER MODELS:
The Seisco Supercharger is a new technology designed to connect to the main water
heater tank regardless of its primary heating source (gas, electric, solar, heat pump,
geothermal, heat recovery). The Supercharger is designed to avoid scald potential by not
heating water that is already hot and only incrementally adding the precise amount of heat
to maintain the desired set point. It can recognize very small temperature changes so as
the water in the tank drops below its pre-set desired temperature, the Supercharger
increments the heat required to maintain the constant desired set point within 1.5 degrees.
Supercharger Models should be connected to the HOT water line. They can be connected
directly adjacent to the main hot water source as an extender or near the desired point of
use as a booster. System must be properly sized to provide sufficient hot water for the
desired number of fixtures to be served. Contact your dealer or SEISCO sales
representative for assistance in sizing for your application.
All SEISCO models are temperature rather than flow controlled, the Supercharger will
modulate and add only the amount of energy necessary to maintain the hot water set point
and return to standby once hot water from the primary hot water source reaches set point
offering energy AND water savings.
