Start - Running - Parking
1 Before starting, with 500 V M D meter to measure the grounding insulation resistance value of electric
pump should be not less than 5 MQ. (usually get data in 12 hours after installation). •2 when starting ,
observe the current, voltage is an accordance with the prescribed scope, or abnormal sound operation and
vibration phenomenon, if abnormal should be solved in time.
In the running of electric pump keep observe the voltage, current, the change of flow and head,
if find one of the following descriptions, stop mnning.
The current under rated voltage, which more than rated value;
Under rated head, the drop value of flow bigger than the normal position;
insulation resistance below 0.5 M n;
internnittently water come out from pump;
Pumps have suddenly sound or larger vibration;
Allow Horizontal or obliquely installation range
