Easy Connect (EZConnect™) INSTRUCTIONS
EZConnect Installation
1. EZConnect allows the installation of two Water Heater units together utilizing the EZConnect
cord.
2. Install the two Water Heater units 2" ~ 18" apart so that the cord will be able to reach between
two units.
3. Do not install more than 18" apart between two water heaters. To do so, will cause temperature
fluctuations (cold water sandwich effect) whereby the water is shut off, then turned on again.
4. The EZConnect shall be disabled before installing with the MSA controller system.
