The EZConnect™ cable is an optional accessory
that connects 2 water heaters and allows them to
function as one hot water source.
The MSA-2M and MSA-2S packs are optional
accessories that connect 2 to 5 water heaters
and allow them to function as one hot water
source.
Refer to the instructions that come with the
accessory for complete installation information.

Guidelines
• Do not install both the EZConnect™ and the
MSA packs because they are not designed to
operate together.
• Water heaters connected with the
EZConnect™ Cable or the MSA-2M and MSA-
2S packs cannot be used for the bath fill
function.
• Water heaters should be installed less than 18
inches apart so that the cables will reach
between units and to prevent temperature
fluctuations (cold water sandwich effect) when
the water is shut off and turned back on.
• Temperature settings can only be changed on
the controller for the primary unit.
