EcoSmart ECO-11 Installation Instructions Manual - page 12
Your new electric tankless water heater requires no maintenance. However, to ensure maximum
performance of your water heater and to reduce the risk of a water leak, we do recommend the following
maintenance:
You should inspect the CONNECTIONS on the inlet and outlet of the water heater at least on an annual
basis for any signs of damage or failure. Any signs of damage, cracks, leakage or weakness should be
replaced. Take care not to over-tighten the connections. Serious internal damage to your water heater
can occur if you over-tighten the water heater connections at the unit.
IMPORTANT NOTES:
As with all electrical appliances, under no circumstances should you attempt to install, repair or
disassemble this water heater without first shutting off all power to the unit directly at the fuse or breaker
box. SERIOUS BODILY INJURY OR DEATH COULD OCCUR IF YOU IGNORE THIS WARNING.
When any maintenance is performed on the water heater or the home’s plumbing system that may
introduce air into the plumbing pipes, it is important to turn the power off to the water heater and purge
the air out of the lines before allowing the unit to power up. FAILURE TO DO SO COULD CAUSE
PERMANENT DAMAGE TO THE HEATING ELEMENTS.
If you have a water supply with a high level of mineralization (hard water), you should increase the
frequency of your maintenance.
