3. Inspection of thermal and moisture sensors if provided:
Identify control cables. Mody Pumps provides a reference such as color-coded labels
or sticker on the cable.
a. Probe Sensor. Normally open
Using a multimeter and setting it on the Ohm resistance mode, connect meter
terminals to wires (Probe) and Green (Ground) and check for ohm resistance. An
open-connection reading must be obtained, otherwise pump has a wet stator or
water in the oil chamber which may require further inspection of the complete pump
unit.
b. Thermal sensor: Normally closed
Using a multimeter set the instrument on ohm-resistance mode and connect
terminals to wires Thermal 1 and Thermal 2. These terminals represent the thermal
switches embedded in all three windings connected internally in series and should
show continuity indicating a normally closed circuit. In the event there is no reading
indicating an open circuit the stator will have to be removed for further evaluation.
All pumps and control panels must be properly grounded.
4. Installation:
a. Ensure site voltage corresponds with voltage value stamped on pump nameplate.
b. Check for pump rotation before installation . Improper rotation may result in poor
pump performance and can damage the pump motor. Pumps are provided with tags
that show the rotation of the impeller and the Kick start. The kick start, thus rotation
can be checked by energizing the pump for a short period of time. If the “kick” is not
noticeable suspend pump freely and energize it momentarily. Shift any two phases
in the power supply if the kick is wrong.
Do not operate Pump in reverse rotation - severe damage may result.
c. Lifting:
Do not lift or pull the pump under any circumstances by means of the power cable.
Always lift pump by securely fitted lifting hooks/eyebolts provided with pump.
