Check the power supply. Check the circuit breaker.
Ensure the breakers at main electrical panel are ON.
A breaker may be faulty or the unit may be wired
incorrectly.
Ensure the shutoff valve on the unit's incoming water
supply line is fully open.
Increase the flow rate from the water supply source.
Clean the filter screen on the unit's water inlet.
Refer to this manual for reset points. Ensure all power
is shut off at the breaker panel before attempting to
reset the unit. Press all resets.
Call Customer Service.
Reduce the flow rate at the faucet or slightly close the
shutoff valve on the unit's incoming water supply line
to reduce flow rate
This water heater is designed to operate on 240 volts.
A lower voltage will produce less heating power. It
may be necessary to upgrade to a larger input heater.
Double check the wiring. Ensure it is correct.
Increase the temperature setting on the unit
Make sure the shutoff valve is fully open and the
water supply line is not blocked
It is not necessary to mix as much cold water with a
tankless water heater as with a conventional storage
tank. Also, an anti-scald feature may be installed
on the faucet that is mixing cold water. These types
of features can usually be adjusted to reduce the
amount of cold water mixed.
As hot water runs through the system to the faucet,
some heat will be lost, especially if it has a long
distance to travel or the pipes are cold. This is normal
and can be compensated for by increasing the
temperature setting and insulating the pipes.
Contact a qualified electrician or your local authorized
distributor for service
Increase the flow rate from the water supply source
