WARNING
If your water heater requires a reset, be sure to TURN OFF THE BREAKERS prior to resetting the unit. Resetting your unit without turning off the breakers can result in personal injury and damage to your water heater.
WARNING! There is water contained in the coils of your water heater at all times. If your water heater is exposed to freezing temperatures, the water in the coils could freeze, causing a break in the heat exchanger of the unit, or the supply and return lines. This kind of damage will result in water running freely into the space where the water heater is located, which can cause flooding. DO NOT install this water heater where it may be subjected to a freeze. If your water heater is in an area where freezing is a possibility, you must turn off the water to the heater and drain it of any water by disconnecting the water lines. Leave the water lines disconnected until you intend to use the water heater.

Quick Start Guide
iE-18 | iE-24 | iE-27
1) Mounting
Mount vertically on a flat surface (i.e. board or wall) larger than the unit itself. Make sure the bracket is secure by utilizing a stud or the provided wall anchors. Keep away from any potential splashing or leaking water and strong magnetic fields.
2) Water connections
When installing your water connections make sure to use 3/4” NPT fittings. Please use the provided gaskets to prevent leaks. When tightening fittings use a backup wrench on inlet and outlet fittings (flat sides of fittings are located behind the front cover). It is recommended to install a high-pressure discharge valve and a shut-off valve on the incoming water line, in that order. Open a faucet and run water through the unit for a few minutes to purge out air, turn off at faucet to build up pressure in the line to check for leaks.
3) Electrical connections
Wiring for electrical connection will differ depending on the model please double check the model type on the right side of the unit.

4) Operation
Unit is activated by the flow of water through the inlet. A desired temperature set point is selected by using the “up” or “down” buttons, if unit does not respond push the center “power” button and try again. Test water to prevent scalding.

WARNINGS
This is not a do-it-yourself project. Failure to have this appliance installed by a licensed plumber and electrician will void all warranties.
Under no circumstances should you attempt to install, repair or disassemble the Eccotemp tankless electric water heater without first shutting off all power to the unit directly at the circuit breaker box.  Installation of this product is restricted to indoor locations only by a licensed plumbing or electrical contractors.

PRODUCT FEATURES

The Eccotemp iE Electric tankless water heaters include patented technology with multi-safety devices, including
the following features:

1. Tankless, instantaneous heating for on-demand hot water, No pre-heating. No stand-by heating loss. Energy-saving.
2. Micro-computer control, adopting patented heating technology. Water is completely separated from electricity by multi-layers of composite nano insulation material.
3. Over-heating thermal cut-off to avoid scalds. Once the outlet water temperature reaches 153°F/ 67°C, the electricity is automatically cut off. If this occurs, the screen will beep and display an E1 error code.
4. Malfunction sensor. If there is a malfunction with the temperature sensor, the heater will stop working and display an E3 error code.
5. Dry-heating thermal cut-off. In the case of dry heating, the unit’s electricity will be cut off and it will display an E4 error code.
6. Eccotemp Product Advantage: Eccotemp iE heating elements are made from a single piece of cast aluminum; so there will never be water leakage, nonelectric leakage in the heating chamber.
