RESIDUAL RISKS

Falls from the machinery
The pump has been designed to be lifted manually, without the need for any equipment. Pay attention to the possibility of breakage or injury caused by falling equipment. Handling of the pump should be carried out using suitable footwear.

Rotating parts
During normal operations, all rotating parts are protected against accidental or incidental contact; these protections can, however, be removed (e.g. fan cover).

The following is recommended:

• All maintenance operations should be carried out with the system switched off, protecting automatic restarting.
• All protections should be reinstalled once the work has been completed.

Electrocution
During normal operations, electrical contacts are protected by mechanical barriers which can, however, be removed. The danger of electrocution is increased by the presence of a humid environment. The following is recommended:

• Electrical connections should be carried out only by qualified personnel in compliance with local laws.
• Always check that there is no voltage on the equipment during interventions.

Burns
The electric motor can reach temperatures that can burn those who accidentally come into contact with it. The following is recommended:

• Do not touch the motor when in operation.
• Wait until the motor cools down before carrying out interventions.

Spills
The pump has been designed to be used with swimming pools and similar applications and, therefore, the use of chlorinated or otherwise chemically modified water is foreseen. The following is recommended:

• Dispose of any hazardous substances by local laws.
• Empty the pump before a long idle period.
• Do not insert products for swimming pools directly into the pump, but follow the instructions of the products themselves.

Suction
The pump sucks in liquid during normal operations; the following is therefore recommended:

• Size the openings in the tank according to stat-of-the-art, and provide adequate protection.
• Do not approach the running pump ports with objects that could get caught or sucked in (e.g. necklaces, long hair, ties).

PERSONAL PROTECTIVE EQUIPMENT

• Protective gloves must be used during scheduled and special maintenance (chemical, thermal and mechanical risk).
• The use of safety shoes or foot protection is recommended for handling.

TRANSPORT AND HANDLING

• Avoid placing excessive weights on top of each other. Make sure that the box is fastened in position during transport.
• No special equipment is required for transporting and moving the product, refer to overall dimensions if necessary.

INSTALLATION

GENERAL INFORMATION
Installation must be carried out in ventilated, weather-protected areas, with the pump axes in a horizontal position and the base facing downwards. Installation in areas with potentially explosive atmospheres is strictly forbidden.

• Provide sufficient space around the pump to ensure ventilation of the motor, check the free rotation of the motor with a screwdriver and the direction of rotation (three-phase only), remove the pre-filter, and fill and empty the pump casing.
• In the case of fixed pools, the electric pump must be installed at least 3 m from the pool edge.
• When used as a portable pump, adequate protection must be provided, and the pump must be installed on an insulating support of at least 100 mm.

PIPES

• Size the piping so that liquid velocity is lower than 1.5 m/s at intake and 3 m/s at drainage.
• Make sure that all pipes are clean before connecting them. Particles of sand or dirt bigger than about 1mm can cause premature wear and performance degradation.
• Isolate the pump by closing the upstream and downstream shut-off valves when testing the pipes for leaks at a pressure higher than 2.5 bar.
• Use plastic pipes and fittings.
• Avoid excessive tightening (just ensure sealing) and anchor the pipes on their supports to avoid weight and vibrations on the pump.
• Avoid the use of shut-off valves with non-adjustable closures to limit water hammer blows. The installation of dampers in the pipes is recommended to prevent water hammering on the (plastic) structure of the pump.

Suction pipes

• Suction pipes must be perfectly sealed to prevent air from entering the system. In the case of installation below water level, a gate valve must be fitted to both the suction and discharge lines – as close to the pump as possible – to isolate the pump from the system.
• In the case of installation above water level, with several suction pipes (e.g. for skimmers, bottom drain, cleaner connection) connect all pipes to a manifold with a dedicated gate valve and connect only one vertical pipe to the pump.
• The manifold must be below the water level.
• If flexible pipes are used, reinforcing spirals must be fitted at the suction side to prevent cross-sectional reductions in the pipes due to intake depression.
• Ensure that all suction lines have a slight slope to avoid air pockets.

Pump above water level (suction operation)

Pump below water level (suction operation)

Delivery pipes
Always install a gate valve to regulate flow rate and head adjustment. Provide also the installation of a pressure gauge for pressure reading.

ELECTRICAL CONNECTION

• Electrical connections must be carried out by qualified personnel under local regulations.
• The protective conductor (‘earth’) must be connected to the terminal marked with the earth symbol .
• An earth leakage circuit breaker with residual current (IΔN) ≤ 30 mA must be inserted in the supply circuit for use in swimming pools, tubs, or similar. Install a mains disconnection device with a contact opening distance of at least 3 mm. Damaged power cables must be replaced by the manufacturer or technical service, or by qualified personnel.
• The electric pump must be fitted with a rubber power cable no lighter than type H07 RN-F (245 IEC 66).

STARTUP, USE, AND SWITCH OFF

CHECK BEFORE SWITCHING ON
The electric pump must not be started up if there are damaged parts.

FIRST START-UP

• Check the free rotation of the motor shaft using a screwdriver inserted into the notch on the fan side of the shaft. Rotate by hand only in the direction indicated by the arrow on the fan cover. Do not start up the pump if the shaft is blocked.
• For three-phase versions only: check the direction of rotation (clockwise when looking at the pump from the fan side) by starting the pump for a few seconds. If not, disconnect the power supply and reverse the connections of the two phases.

Caution:
If the shaft turns backward, the impeller may unscrew if blocked. In this case, it must be repositioned according to the instructions in the “pump disassembly” section.

FILLING

• In the case of installation below water level, fill the pump by slowly opening the suction gate while keeping the drainage gate open to let the air out.
• In the case of installation above water level, unscrew the knobs and remove the cover; fill the pump body with water up to the level of the suction inlet (see figure).
• After starting up, adjust the pump by acting on the discharge gate valve to check that the pump is working within the range indicated on the nameplate and that the current absorbed is not exceeded.
• Avoid indoor operations (fully closed discharge gate) for prolonged periods.

SELF-PRIMING
Self-priming is the ability of the pump, when installed above water level, to suck in air from the suction pipe and, after a time of up to 10 minutes, start pumping water.

Caution: the height from the water level to the pump inlet must not exceed 4 meters.

• If the suction height is more than 1.5 m, a non-return valve must be inserted in the suction pipe. In this way, the suction line will not empty in the event of a stoppage (e.g. for pre-filter cleaning) and the pump restart time will be shorter.
• The length of suction pipes should be reduced as much as possible to decrease priming times.

Priming conditions:

• Pump housing filled with cold water up to the suction inlet.
• A non-return valve was installed on the suction pipe.
• Suction and drainage gate valves are fully open.
• Prefilter not obstructed.
• The suction pipe is perfectly sealed and immersed in water.
• Perfect seal of O-rings and mechanical seal of pump.
• Cover knobs and water drain plugs tightened by hand.
• Pressure pipe without non-return valve and with at least 80 cm of straight section after the pressure port (the length of the straight section can be reduced in the case of low suction heights; to be checked during installation).
• If priming has not taken place after 10 minutes (check through the transparent cover), check the above conditions and reset where necessary.
• If the water level drops below the skimmers or other suction nozzles (e.g. when emptying the pool), keep only the gate valve on the suction pipe open.

SWITCHING OFF

• The product is designed for continuous operation; shutdown can be carried out only by switching off the power supply.

MAINTENANCE

SCHEDULED MAINTENANCE (CARRIED OUT BY THE USER)
Ensure that the power supply is switched off and that the pump cannot be powered up, even inadvertently, before any maintenance work.

Cleaning the pre-filter

• In the case of installation below water level, close the inlet and outlet gate valves before dismantling.
• Cleaning of the prefilter must be carried out depending on the frequency of use and the presence of impurities in the water (e.g. leaves):
  • unscrew the cover closure knobs
  • remove the cover using a screwdriver, pry off the appropriate seats
  • remove the prefilter and clean it, removing any bodies obstructing the water passage holes.
• Clean the transparent cover if necessary using only soap and water. Do not use solvents. Do not lubricate the cover O-ring with oil.
• When cleaning is complete, replace the prefilter and close the cover by screwing the knobs by hand as far as they will go. Do not screw on using pliers or other tools.

Emptying the pump casing
In the event of long periods of inactivity or possible frost, the pump casing must be emptied of any water that may have remained inside. Simply unscrew the drain plugs shown.

SPECIAL MAINTENANCE

• Special maintenance must be carried out by qualified personnel since it foresees the use of tools, and requires in-depth knowledge of the equipment. Operations regarding the dismantling of the pump, and replacement of the mechanical seal will be described.
• Please refer to the exploded diagram on the PEDROLLO spare parts site for the order to disassemble and reassemble the parts.

Removing the pump

• Disconnect the pump power cable from the mains.
• Close the delivery and suction gate valves.
• Disconnect the pump from the delivery and suction pipes.
• Empty the pump casing (see chapter on Emptying pump casing).
• Unscrew and remove the body-base fixing screws.
• Unscrew and remove the motor body-mounting screws.
• The pump casing can now be removed from the structure.

Replacing a mechanical seal

• The impeller must be removed when replacing the mechanical seal.
• Insert a flat-blade screwdriver into the notch on the motor shaft on the fan side (remove the fan cover if necessary).
• Block the impeller by hand and unscrew it by turning the shaft with the screwdriver anticlockwise. (The fan and fan cover can also be removed if necessary, and the shaft end clamped with a vice or other suitable tool).
• Remove the impeller. The rotating part of the mechanical seal is also removed with the impeller.
• Remove the rotating part of the seal.
• Remove the fixed part of the seal from its housing.

Reassembly of the mechanical seal

• After replacing the seal, reassemble the rotating part on the impeller housing by pushing it to the stop and the fixed part on the cover housing.
• Lubricate the seal with alcohol or water.
• Reassemble the impeller on the shaft, holding it with one hand and screwing the shaft clockwise with a screwdriver until the impeller is locked on the stop shoulder.
• Only for three-phase versions: to prevent unscrewing of the impeller in the case of reversed phases, clean the threaded end of the shaft and apply a weak thread-locker (e.g. Loctite 222). Check the direction of rotation before putting water into the pump if If there is no threadlocker.
• Complete reassembly by performing the assembly steps in reverse order.
  • Tighten the motor body-support locking screws with alternating crosswise turns on diametrically op-posite positions with a tightening torque of 7 Nm.
  • Tighten the body-base anchor screws to a maximum torque of 3 Nm.
