Environmental enclosure ratings
According to UL 778/C22.2 No 108-14, pumps intended for outdoor use must be marked enclosure type 3 and
the product must be tested at a surface temperature down to -31 °F (-35 °C). The MLE Model J enclosure is
approved for NEMA type 3 or 4 and is rated at a surface temperature down to 32 °F (0 °C), thus it is only for
indoor use in UL 778/C22.2 No 108-14 pump applications.
The MGE, MLE Model K enclosure is approved for NEMA type 12 and is suitable for indoor use only.
For more information about ambient temperature during operation, see the sections on operating conditions and
ambient temperature.
