terminal box with an opening suitable for a ½" NPT conduit hub.
Ratings – The pumps operate at 115 Vac, 1.5 to 1.6 A, or 230 Vac, 0.7 to 0.8 A, depending upon model type.
The pumps are rated for an ambient temperature range of -20°C to +40°C.
Model types – Approved model number variants are as defined below. Refer to Installation and
Operation Instructions document BE420003 for further details concerning model types.
