Outside Enclosure Overview
The enclosure for the Liqui-tect panel’s controller board comes in two sizes:
• The large enclosure is designed to accommodate the Transformer Module and future compo-
nents, in addition to the controller board.
• The small enclosure is built to hold the controller board only.
Both enclosures are 2-3/4" deep.
Both enclosures have a built-in liquid crystal display (LCD) and a key lock, as shown in the example
below. The metal enclosures accommodate secure conduit fittings and protect components against
external forces and debris.

The enclosure must be secured to a wall, either flush-mounted or recessed in the wall, as described in
2.0 - Installation. Knockouts and access slots on the top and bottom allow easy connection of wires
and cables (see 3.0 - Connections and Configuration) with either mounting type.
