PLUMBING INSTALLATION
CAUTION: Breaker must remain off until installation is complete.
Step 1: Flush cold water line to clear any debris before connecting to unit.
Step 2: Install a shut off valve and pre filter (Not Supplied) to prevent any
particles entering the unit that may clog or damage the internal parts.
Step 3: Using flexible lines, connect the Cold Water line to the water heater
inlet labeled as “cold”. Connect furnished Water Valve to the water heater
outlet labeled as “hot”. Connect the HOT WATER outlet line to the Water Valve.
Step 4: Verify all fittings are tight and secure. Open hot water source and
allow water to run though the water heater for at least 1 to 2 minutes. This
will purge the air from the water lines and must be performed prior to turning
on the power at the unit. This is a Mandatory step to prevent Damage to
Heating Elements.
DO NOT solder any fittings to unit. This will damage internal sensors and
components and void the warranty. Use flexible lines and screw fittings only
to unit.
A TP valve is not required in most jurisdictions. Verify your local codes
accordingly and if required install on outlet side only.
Verify all connections are free of leaks.
