• Remote control enclosure must be mounted on vertical
wall and installed in vertical position. Mounting remote
control enclosure in horizontal position may result in
collection of liquids and lead to electric shock.

exceeds 50 V (extra low voltage). Enclosure is marked
with the following hazard identification symbol:
NOTE: A qualified electrician should connect the unit(s) to a
power source. A qualified plumber should connect the
water supply and drain(s).
NOTE: Refer to the Installing an Auto-Fill Unit before installing
a Remote Control Enclosure.

Refer to the “Control Enclosure Cutout Dimensions” chart
for the cutout dimensions for each control enclosure.
• The cutout depth required for all control enclosures is
5″ (127 mm).
• Make sure to have enough space inside the cutout if
installing with conduit on the side of the control enclosure.
• For units with two control enclosures: If the unit is
equipped with Auto-Fill, each enclosure cutout size will
be different (see chart).
