If the pump is equipped with an H05 power supply cable it is not suitable for use with pools, ponds or similar.
If the pump is equipped with an H07 power supply cable it is only suitable for use with pools if no one is in the water. (Please refer to fig.1)

INSTALLATION

DANGER – ELECTRIC SHOCK RISK
When installing, please ensure pump is disconnected from electrical supply.

WARNING
Make sure that float switch turns off pump, when at min. level of liquid.

WARNING
Make sure no obstacles are in the way of float switch, when it is in motion.

DANGER
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.

• Please use handlebar to move or lift pump
• Please use a non-return valve in case pump is connected to fixed installation with rigid piping; this will avoid liquid circulating when pump has been turned off; it is advisable to install a quickly disconnecting connection on the delivery pipe to make it easier to disconnect the pump for cleaning and maintenance
• Please use flexible pipe connected to the pump by means of plastic fittings in case of temporary use of pump
• Use a rope to immerse pump and fasten it to pump’s handlebar
• The automatic PRATIKA® model is equipped with a pre-set float switch (See fig.1) to change the adjustement increase or decrease the free piece of float switch cable by making it slide through the proper seat on the handlebar
• There can be particular requirements for pumps used in or next to pools, garden ponds or similar places.

ELECTRICAL CONNECTION

WARNING
Ensure tension and frequency of electropump (read plate) and power supply are same.

DANGER – ELECTRIC SHOCK RISK
Installer must make sure that electric current network has ground wire conforming to current laws.

DANGER – ELECTRIC SHOCK RISK
Make sure that electric current network is provided with a high-sensitivity circuit breaker ∆=30 mA (DIN VDE 0100T739).

SINGLE PHASE VERSION

Single phase pumps are equipped with plugs with double ground contact at top end of power supply cord; in this case grounding is done when plugging in.

OVERLOAD PROTECTION

Single phase PRATIKA® range pumps have a built-in thermal overload with automatic reset . Further protection devices are not required.

STARTING THE UNIT (SEE FIG. 1)

WARNING
Use the electropump for the type of uses listed on the plate.

WARNING
Do not let electropump run dry, the hydraulic parts and seal could be damaged.

WARNING
Do not run the electropump with the interception valve on delivery completely closed.

• Before starting the electropump, connect the pipe to the (1″ ¼) delivery inlet, using the provided plastic fitting or other commercial pipe fittings
• Connections must be made so as to avoid losses
• Start the pump by inserting the plug in an appropriate outlet

MAINTENANCE AND TROUBLESHOOTING

DANGER – ELECTRIC SHOCK RISK
Before doing any operation, make sure machine is disconnected from electric power supply.

DANGER – ELECTRIC SHOCK RISK
Power cord must be replaced by manufacturer or by Customer service, using special tools.

Under normal conditions electropumps in the PRATIKA® series do not need any maintenance. Occasionally it may be necessary to clean the filter or other hydraulic parts. If the electropump is not going to be used for long periods of time (e.g. an entire season) it should be emptied completely, rinsed with clean water and put in a dry place

CLEANING THE FILTER

If the water being drawn is not perfectly clean, it may be necessary to clean the pump using a steel brush to scrap accumulated dirt off the outer surface, afterwards, without dismantling the pump, rinse the filter with clean water.
If this is not sufficient then clean the hydraulic parts.

CLEANING THE HYDRAULIC PARTS

• Unscrew nuts holding the filter
• In sequence remove the filter and suction flange
• Holding the impeller still, unscrew the locking nuts
• Remove the impellers and diffusors one at a time
• By loosening the tie rods, it is possible to disassemble the delivery flange to gain access to the mechanical seal
• Carefully wash the parts
• To assemble follow steps in reverse order

if there is power and if the plug is plugged in properly
Motor protection tripped.| Verify the cause and reset the switch. If the thermal has tripped wait until the system has cooled
Defective condenser| Replace the condenser
Shaft blocked.| Verify the cause and unblock the electropump.
THE MOTOR RUNS BUT THE ELECTROPUMP DOES NOT PUMP LIQUID| It is taking on air.| Make sure that the joints are airtight. Check that the level of liquid has not dropped below the minimum priming level.
Wrong rotation direction.| Reset the rotation direction.
Suction grate blocked.| Clean suction grate.
Non return valve blocked.| Clean or replace valve.
THE ELECTROPUMP STOPS AFTER RUNNING FOR A SHORT PERIOD OF TIME BECAUSE ONE OF THE THERMAL MOTOR PROTECTION DEVICES TRIPS| Power supply does not conform to data on plate.| Check the voltage on the power supply conductor cables.
A solid object is blocking the impellers| Dismantle the electropump and clean it.
The liquid is too thick.| Change electropump type.

If the problem has not been eliminated after carrying out the above operations contact the closest service centre.
