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.
Accessories Necessary:
(1) EZConnect Cable
(1) MSA-2M
