You must keep the motor fan-cover clean. Your pump may overheat if the air-flow over the motor is restricted.

periodic testing of electrical equipment. We recommend that the earth continuity is less than 0.1 : and the
insulation resistance is greater than 10 M:. If the motor fails these tests, you must replace the motor.
