EcoSmart ECO 16 Installation Instructions & Homeowner's Manual - page 5
STEP 1 Bring the HOT WATER and COLD WATER lines to the heater. We recommend that a manual shut-off
valve (ball valve) be installed on the inlet side of the water heater so there is a convenient shut-off point
available in the event that future maintenance or servicing is required. Before connecting these pipes to
the water heater hoses if used, it is extremely important to FLUSH the lines to eliminate all plumbing paste or
residue in the lines caused by any welding or soldering. We recommend using flex water heater hoses for ease
of installation.
STEP 2 Connect the HOT WATER line to the water heater marked HOT WATER OUT located on the left side of the
heater when facing unit. Connect the COLD WATER line to the water heater marked COLD WATER IN on the right
side when facing unit. DO NOT USE TEFLON TAPE OR PASTE on fittings.
STEP 3 After tightening both fittings at the water heater, open several hot water faucets and allow 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. 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.
STEP 4 Carefully inspect all connections, unions, and the pressure relief valve (if installed) for leaks.
STEP 5 If your water heater is installed on a second floor, heated attic, or other location where water damage
could occur a water pan is required.
5- ELECTRICAL INSTALLATION
PLEASE READ THESE INSTRUCTIONS THOROUGHLY AND COMPLETELY BEFORE INSTALLATION AND BEFORE
USE. FAILURE TO DO SO COULD CAUSE PROPERTY DAMAGE, SERIOUS PERSONAL INJURY, DEATH AND
VOID YOUR WARRANTY.
This product must be installed by a licensed and qualified electrician in accordance with all applicable national,
state, provincial, and local electrical codes.
As with all electrical appliances, under no circumstances should you
attempt to install, repair or disassembled 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.
All wiring (wire gauge) and circuit protection (breakers) must comply with the U.S. National Electrical Code (NEC)
in the U.S.A., or the Canadian Electrical Code (CEC) in Canada. Failure to do so could result in property damage
and / or personal injury, and void your warranty. Note: the Canadian Electrical Code generally requires that all
supply wires and corresponding circuit protection (breakers) used for domestic hot water heating and hydronic
heating applications be sized to a minimum of 125% of the maximum current rating of the heater (see model
specifications below for details).
Before installing this product, ensure that the home has sufficient electrical power available to handle the
maximum amperage load of the applicable model.
