The Snubber for 103662 Digital Blowdown Timer is a required protective component engineered to safeguard Mr.Steam's Digi 20 Blowdown Timer from electrical noise and voltage spikes. Installed directly between the timer's black and white terminals, this snubber helps the timer maintain accurate, consistent operation even in commercial environments with variable or noisy electrical conditions. Reliable blowdown timing is essential for CU-series commercial steam generators equipped with automatic blowdown, since inconsistent timer performance can disrupt the mineral discharge cycle that keeps the boiler running cleanly. Mr.Steam specifies that a snubber should be installed with every Digital Blowdown Timer, making this a mandatory companion part rather than an optional accessory. Lightweight and straightforward to wire in during installation or service, this genuine Mr.Steam component helps facility operators protect their timer investment and maintain dependable, code-compliant blowdown operation over the long term.
