4- PLUMBING INSTALLATION
Please follow all plumbing instructions carefully. We recommend that this product be installed by a
qualified homeowner. If further assistance is needed, a licensed and qualified plumber in accordance with
all applicable national, state, provincial, and local plumbing codes should be hired.
Plumbing Installation Instructions
Please see installation diagrams on the following pages for visual guidance.
STEP 1:
Using the corresponding fittings for which layout was used, connect the HOT WATER outlet from
your water tank to the INLET thread located on the bottom side of the TankBuddy™ when facing the unit.
Use the nut (B) and ferrule (C) to secure the connection.
Do not over tighten the compression nuts, which
may cause the ferrules to crack and lead to a leak.
STEP 2:
Using the PUSH-TO-CONNECT fitting (F), connect the HOT WATER copper pipe line to OUTLET
thread located on the top side of the unit. Use the nut (E) and ferrule (D) to secure the connection.
STEP 3:
Close the tank drain valve.
Make sure at least one warm water faucet is open in the house.
Re-open the water supply valve on the cold water copper pipe.
You know the tank is full when water is running out of any open faucet in the house.
FAILURE TO FOLLOW THESE STEPS WILL CAUSE WATER TANK DAMAGE.
STEP 4:
After tightening all fittings, open several hot water faucets and allow un-heated water to run
though the water heater for at least 2 to 3 minutes. This process purges all the air from the water lines and
MUST be performed prior to turning on the power at the unit.
FAILURE TO FOLLOW THIS STEP CAN CAUSE PERMANENT DAMAGE TO THE HEATING ELEMENTS.
If 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.
STEP 5:
Carefully inspect all connections, unions, and the pressure relief valve (if installed) for leaks.
STEP 6:
TURN OFF ALL FAUCETS BEFORE PROCEEDING TO ELECTRICAL INSTALLATION.
