PLUMBING
The Ecosmart electric tankless water heater is supplied with 1/2” compression fittings.
Do not weld or use paste or use Teflon on fittings.
Connect the cold water supply line to the right side of the unit ("cold water inlet” in diagram on
page 3).
Connect the hot water supply line to the left side of the unit (“hot water inlet” in diagram on
page 3).
After both water lines are fastened securely, run water through the unit for at least 2 to 3
minutes to flush out any air pockets in the lines (purging). It is recommended that all faucets,
showers, etc. be run during this process. Failure to purge the lines of air can cause permanent
damage to the unit. This procedure MUST be performed before the electrical power is turned on.

ELECTRICAL CONNECTION
● The Ecosmart electric tankless water heater unit must be installed to independent
double pole breakers.
● Each Ecosmart model comes supplied with the required wires for installation.
● Breaker size and wire gauge must meet all applicable local, state, provincial, and
national electrical codes for your area – these are only guidelines that will apply to
most installations.
● Some codes require use of electrical sub-panel for installation, especially when heater
is not mounted within line-of-sight of the main electrical panel. Wiring should be sized
to maintain a voltage drop of less than 3% under load.
● If your home is already equipped with a large number of electrical appliances, you may
require a larger electrical service than the one recommended.
● Check all wires to make sure that they are tightly fastened.
● Before turning the power on, the system must be flushed as required in the plumbing
instructions.
● When the unit is powered up the green LED indicator light will turn ON and then OFF.
This is normal.
