* Note: Mini 2 is internally restricted to 0.32 GPM
-Tankless water heaters are considered a non-continuous load
-Conductors should be sized to maintain a voltage drop of less than 3 % under load
-For use with cold water supply only
12. Troubleshooting
E
Symptom
Possible cause
Solution
No hot water
despite fully
opened hot
water faucet
.
No electrical power
.
Check the circuit breaker and
check voltage at the wiring block
.
The activation fl ow rate needed to
turn on the heating element has not
been reached.
Clean fi lter screen
.
Safety cut out tripped
– turn circuit breakers off
– open Hot Valve to release pres-
sure from the unit
– reset saftey pressure cut out
E
– turn circuit breakers on
