Guidelines
Observe the following guidelines regarding the location of the prod­uct:
• Make sure that no obstructions hinder the normal ing air that is delivered by the motor fan.
• Make sure that the installation area is protected from any fluid leaks, or flooding.
• If possible, place the pump slightly higher than the floor level.
• The ambient temperature must be between -30°C (-22°F) and +40°C (+104°F) unless otherwise
• The relative humidity of the ambient air must be less than 50% at +40°C (+104°F).
Installation above liquid source (suction lift)
The theoretical maximum suction height of any pump is 34 ft. In prac­tice, this is not achieved due to the following conditions affecting the suction capability of the pump:
• Temperature of the liquid
• Elevation above the sea level (in an open system)
• System pressure (in a closed system)
• Resistance of the pipes
• Own intrinsic
• Height differences

2. If the motor is not equipped with automatic reset thermal protec­tion, then adjust the overload protection according to the nominal current value of electric pump (data plate).
5 Commissioning, Startup, Operation, and Shutdown
Precautions
WARNING:
Make sure that the drained liquid does not cause damage or injuries.
NOTICE:
• Never operate the pump below the minimum rated flow.
• Never operate the pump with the delivery ON-OFF valve closed for longer than a few seconds.
• Do not expose an idle pump to freezing conditions. Drain all liq­uid that is inside the pump. Failure to do so can cause liquid to freeze and damage the pump.
• The sum of the pressure on the suction side (water mains, gravity tank) and the maximum pressure that is delivered by the pump must not exceed the maximum working pressure that is allowed (nominal pressure PN) for the pump.
• Do not use the pump if cavitation occurs. Cavitation can damage the internal components.

5.1 Prime the pump

1. Fill plug
2. Drain plug
3. Funnel
Installations with liquid level above the pump (suction head)
Close the on-off valve located downstream from the pump.
Installations with liquid level below the pump (suction lift)
Open the on-off valve that is located upstream from the pump and close the on-off valve downstream.

5.2 Check the rotation direction (three-phase motor)

Follow this procedure before start-up.
1. Start the motor.
2. Stop the motor.
3. If the rotation direction is incorrect, then do as follows: a) Disconnect the power supply.
b) In the terminal board of the motor or in the electric control
panel, exchange the position of two of the three wires of the supply cable.
c) Check the direction of rotation again.

6 Maintenance

5.3 Start the pump

1. Start the motor.
2. Gradually open the on-off valve on the discharge side of the pump.
At the expected operating conditions, the pump must run smoothly and quietly. If not, refer to Troubleshooting (page 6).
3. If the pump does not start in correctly in 30 seconds, then do the following:
a) Switch off the pump. b) Reprime the pump. c) Start the pump again.
4. Switch off and on the pump (for about 30 seconds of continuos running) and make sure that all the trapped air is bled out by re­peating this 2–3 times.
NOTICE:
Make sure that the pump has bled away all the trapped air. Failure to do so can harm the product.
6 Maintenance
Precautions
Electrical Hazard:
Disconnect and lock out electrical power before installing or servicing the unit.
Problem Cause and solution The pump starts
up but the ther­mal protector is triggered after a short time or the fuses blow.
The pump starts but does not de­liver any liquid.
The pump’s de­livery is re­duced.
• The power supply cable is damaged, the motor short circuits or thermal protector or fuses are not suited for the motor current. Check and re­place the components as necessary.
• The thermo-overload protection (single phase) or of the protection device (three-phase) trips due to excessive current input. Check the pump working conditions.
• A phase in the power supply is missing. Check the power supply.
• The pump is clogged with solids and the impel­ler becomes bound. Clean the pump.
• Air is entering the suction piping, check the liq­uid level, the tightness of the suction pipes and the operation of the foot valve.
• The pump is not correctly primed. Repeat the instructions in Prime the pump (page 5).
• Check for restrictions in the piping system.
• Wrong rotation of the impeller (three-phase). Check the direction of rotation.
• The pump is not correctly primed. Repeat the instructions in Prime the pump (page 5).
WARNING:
• Maintenance and service must be performed by skilled and qualified personnel only.
• Observe accident prevention regulations in force.
• Use suitable equipment and protection.

6.1 Service

The pump does not require any scheduled routine maintenance. If the user wishes to schedule regular maintenance deadlines, they are de­pendent on the type of pumped liquid and on the operating conditions of the pump.
