MAINTENANCE
Electric Shock Hazard. To prevent SERIOUS INJURY or DEATH, ALWAYS disconnect power supply
before installing or servicing.
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 MODEL 3 AND VOID YOUR WARRANTY.
Heatworks recommends the following maintenance:
•
Annually inspect the connections on the COLD | INLET and HOT | OUTLET of the water heater
for any signs of damage or failure. Any signs of damage, cracks, leakage or weakness should
be addressed.
•
Periodically disconnect the COLD | INLET connection and inspect the filter screen for any
debris that may have been flushed through the system.
•
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.
