    September 08, 2026 1 min read

    Engineering dimension drawing for the WaterCop WCDNM Classic non-motorized control/receiver unit.

    Full text manual (for reference)

    Engineering dimension drawing for the WaterCop® Classic Non-Motorized Control Unit (WCDNM), part of DynaQuip's WaterCop® automatic water shut-off system.

    Overview

    The WCDNM is the control/receiver enclosure for a WaterCop® Classic automatic water shut-off system. It's the "non-motorized" designation because the unit itself doesn't drive a valve motor directly — instead, it acts as the wireless (418 MHz) controller/receiver that interfaces with a separate motorized valve actuator via its auxiliary I/O port and cabled outputs.
