Installation Manual
Energy Controller
Model EC
PLEASE READ INSTRUCTIONS CAREFULLY BEFORE INSTALLING
The design anticipates the proper installation and care in use of the
product. There is risk of property damage and personal injury inherent in the
use of any hot water system. The Company cannot supervise the installation
and therefore makes it a specific condition of the warranty that the customer will
supervise the installation and use of this product to be sure they are performed
in accordance with safe guidelines and proper local or national codes.
Generalized instructions and procedures cannot anticipate all
situations. For this reason, only qualified installers should perform the
installation. A qualified installer is a person who has licensed training or a
working knowledge of the applicable codes, regulations, tools, equipment and
methods necessary for safe installation of an electrical component on a
residential water heater.
If questions regarding installation arise, check with your local plumbing
and electrical inspectors for proper procedures and codes. Local codes take a
precedent over instructions in this manual.
The energy controller (EC) is basically a timed switch that interrupts
power going to the controlled elements of the water heater based on the control
program. The EC does not control the temperature of the water heater.
