CASCADING MULTIPLE WATER HEATERS
The Dual Connect Cable Kit (AGTDC1) is an optional
accessory that connects 2 water heaters and allows
them to function as one hot water source.
The Multi Connect Kit (AGTCK1) and the Multi Connect
Cable Kit (AGTMC1) are optional accessories that
connect 3 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 the Dual Connect Cable Kit (AGTDC1)
with the Multi Connect Kit (AGTCK1) and the Multi
Connect Cable Kit (AGTMC1) because they are not
designed to operate together.
• 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.
