Connecting Multiple Water Heaters

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 connects 2 to 5 water heaters and allows 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.
