Raypak 122-322 manual Flow Switch, Low Water Cut Off Optional

Flow Switch

Dual-purpose control shuts off heater in case of pump failure or low water flow. Mounted and wired in series with the main gas valve. Check with Manufacturer for proper paddle size. Utilize correct paddle size for prop- er operation.

NOTE: Flow switch will not operate if flow is less than 20 gpm.

Low Water Cut Off (Optional)

The low water cut off automatically shuts down the burner whenever water level drops below the level of the sensing probe. A 3-second time delay prevents premature lockout due to temporary conditions such as power fluctuations or air pockets.
