Mini ™ 2-1 models are internally restricted to 0.32 gpm. Mini ™ 2-1, 2.5-1, 3-1 ship with a 0.5 gpm pressure compensating fl ow reducer/aerator that should be installed.
Mini ™ 3.5-1, 4-2 ship with a 0.66 gpm pressure compensating fl ow reducer/aerator that should be installed.
-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
