How To Clean An Auto Draw-Off Valve

October 31, 2022

It is critical to clean the ball valve portion of your Automatic Draw-off Valve regularly. Especially when boiling RO-concentrated sap or when operating a
Smoky Lake High Output pan set, the ball of the valve naturally accumulates crystallized sugar sand, inhibiting free movement, and causing early fatigue of the actuator. 

To clean the valve, use a 21/2 mm allen key to separate the valve from the actuator. (Fig A) The actuator remains tethered to the power cord and cannot get wet. 

Then, use a pliers to rotate the stem of the valve (Fig B) so that the ball is roughly half open. (Fig C) Soak the valve/fittings in a 50/50 mixture of white vinegar and water overnight if possible, or at least for a few hours. Rinse, wipe dry, and reassemble. You are all set.
