This guide is for use by qualified electrical professional and/or homeowners.
This guide takes you through a sequence of steps that MUST be
followed. Skipping steps will prevent you from being able to
successfully detect and resolve a problem.
All electric tankless units are designed to be checked with a multi-clamp
volt meter (pictured right) to measure for both voltage and amperage.
Below is an inside view of an electric tankless water heater.
Always write down any volt meter readings/results before contacting
technical support.
NOTE:
When the power supply voltage is lower than 115V, the water heater is
in a non-powered state and stop working.
The rated voltage is 240VAC. If the connected power supply is 208VAC,
please turn the dial switch on the display PCB to the upper side with a
slotted screwdriver.
For additional help, contact technical support at Monday-Friday, 9:00 am—5:00 pm EST, by

Activity A | Flow Meter Troubleshooting
The flow meter is located on the inlet side of the water heater and has 4 Phillips head
screws and a small black wire (see image above). The flow meter is equipped with a
small propeller that must spin freely counter clockwise in order to activate heater. The
flow meter controls the activation of the water heater by sensing water flow. If the flow
meter is functioning properly, the LED display will illuminate once water is flowing
through the system and will continue to stay illuminated while water is running. If the
LED display not illuminated while water is running, follow the step as below.

Right order as shown in the pictures below
1.Remove 4 screws
2.Open cover with flat head screwdriver
3.Take out rotor and clean Install rotor and check seal ring in position or loose the nuts
in inlet if necessary and take out rotor to clean.
4. Place parts back together making sure the impeller is spinning freely and that all the
components are in it.
5.After tightening the two fittings on the device, turn on the hot water faucet and let the
water flow through the device for about 2 to 3 minutes to ensure that all air is
discharged from the water pipe. If this step is not followed, it may cause permanent
damage to the heating elements.
6.. Turn on power to the unit and verify if the display remains illuminated with water
running. Let water run for approximately 45/60 seconds, within this time the unit should
be heating water.
Note:
1.Turn off the power circuit and shut off water feeding before maintenance.
2.Take care of the water leakage during maintenance.
