5- ELECTRICAL INSTALLATION
We recommend that this product be installed by a qualified homeowner. If further assistance is needed, a
licensed and qualified electrician in accordance with all applicable national, state, provincial, and local
electrical codes should be hired. 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. Make sure to shut off all breakers.
SERIOUS BODILY INJURY OR DEATH
CAN 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 USA, 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 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.
TURN OFF THE ELECTRICAL POWER BEFORE
PROCEEDING.
Electrical Installation Instructions
STEP 1:
Making sure all electrical power is shut off, remove the black,
red
, and
ground
wires from the
existing tank heater coming from the circuit breaker. These wires will now go into the TankBuddy™
through the hole in the unit’s back plate (see wiring diagram and
Connection Reference 1
on the
subsequent pages).
STEP 2:
Using a suitable wire gauge that meets all applicable electrical codes for the size of the breakers
used, run
Line 1 (black wire)
,
Line 2 (red wire)
, and
ground (green wire)
from the home’s main breaker
panel to the TankBuddy™ water heater, through the back plate hole. This is connection reference 1,
specified on page 14.
Note: A separate
ground
conductor for each incoming circuit is required.
STEP 3:
Connect the supplied pigtail cord to the TankBuddy™. See
Connection Reference 2
on page 15.
STEP 4:
Now connect the wires included with the TankBuddy™ (pigtail cord stemming from the unit) to the
existing tank heater. The
black
,
red
, and
green (ground)
wires should all have secure connections.
MAKE SURE THESE CONNECTIONS ARE IN AN ENCLOSED AREA. EXPOSED CONNECTIONS CAN LEAD TO
SERIOUS INJURY OR DEATH.
STEP 5:
DOUBLE CHECK the electrical connections to make sure they are correct and that all wire
connections are tight and secure. Also confirm that the correct breaker size and wire gauge has been used
and confirm that the unit has been connected to a ground in accordance with applicable codes.
STEP 6:
Confirm that all the air has been purged from the water lines prior to turning on power to the unit.
Refer to STEP 4 in the plumbing installation section.
CAUTION:
Ensure that you have made the correct connections. You must follow the wiring connection as
shown to ensure the proper operation of the unit. If you mix up one set of wires with another, the unit will
not operate correctly even though it turns on and otherwise appears to function properly.
