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-21 | iE-24 | iE-27
1) Mounting
Mount vertically on a flat surface (i.e. board or wall) larger than the unit itself. Make sure 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 back-up wrench on inlet and outlet fittings (flat sides of
fittings are located behind 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 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.
