ATTENTION On receiving the unit, check the following points:

– The condition of the outer packaging. If it shows significant signs of damage, formally report it to the person making the delivery.
– Check the condition of the contents. If the contents present imperfections that will presumably prevent the correct operation of the unit, formally report the situation to the supplier within a maximum period of 8 days from receipt.

ATTENTION Storage conditions must be such that they will guarantee the good state of repair of the unit. It is especially important to avoid storing the unit in markedly humid environments or in conditions where brusque temperature changes may occur (resulting in condensation).

4. INSTALLATION

4.1 SITE.

ATTENTION Only qualified personnel should install and connect the unit.

The unit must be installed in a dry site. The site must be equipped with a drainage point in the floor to protect against flooding. If the unit is installed in a humid site, a ventilation system must be installed to prevent the formation for condensation. In cases where the unit is installed in confined areas, a forced ventilation system may be required to ensure that the ambient temperature of 40 °C (104°F) is not exceeded.
Do not store pool chemicals near to the unit.
It is important to leave sufficient clearance to allow for the horizontal removal of the motor block and the vertical removal of the hair filter (see drawing in figure 1).

4.2 INSTALLATION.

The unit must be installed away from corrosive or flammable liquids.
It must be anchored to the floor using two M10 bolts or draw bolts of size 10 diameter and of sufficient length to ensure a secure fixture.
The unit must installed as close to the pool as possible and preferably at an elevation of 0.5 meters below sea level (never more than 3 m) to enable “charged” operation.
The pipes used for the installation must be principally PVC.
The intake pipe must be completely watertight and installed with a downward slope of no less than 1/100, thus preventing the formation of air pockets.
At permanent installations, where the pump is located above the water level (SUCTION INSTALLATIONS), the intake pipe must be equipped with a foot valve and every effort must be made to ensure that the majority of the pipe is located below the level of the pump intake shaft until reaching the point that vertically coincides with the shaft. The intake pipe must be a rigid pipe.
At permanent installations where the pump is located below the water level, a stop valve should be installed at both the intake and the discharge.

5. ELECTRICAL CONNECTION

DIN Standard 4844-W8
The electrical installation must fully comply with the Regulations and Supplementary Technical Provisions in force in each country and must be carried out by an authorised installer.

DIN Standard 4844-W8
DANGER
Dangerous voltage may cause shock, burns or even death.
Connect to ground before connecting the power. The power supply must be equipped with neutral and earth conductors.

5.1 VOLTAGE.

The supply voltage to the motor must match the voltage indicated on the unit’s rating plate, with a permitted variation of + 10%. If the supply voltage is less than 90% or greater than 110% of the voltage indicated on the rating plate, contact the power supply company.

Do not connect a three-phase motor to a single-phase power supply or vice- versa.

5.2 ELECTRICAL PROTECTION.

The installation on the fixed wiring of an electrical connection/disconnection, protection and switching system which includes all necessary and recommended elements is compulsory. The system must be equipped with:

A disconnecting circuit breaker that guarantees omnipolar disconnection, directly connected to the power supply terminals and with contact separation on all of its poles, providing total disconnection in overvoltage category III conditions.

Short-circuit and overload protection devices on motors.
Power supply via a residual current device (RCD) (differential switch), which has an assigned operating current not exceeding 30 mA.

The unit must not be operated without additional protection (i.e. motor protection relay).
The characteristics and settings of such devices must be suitable for the equipment to be protected and the expected operating conditions. The manufacturer’s instructions must be followed at all times (see rating plate).

See section 10. “TABLE OF CONDUCTORS AND CIRCUIT BREAKERS”.

5.3 ELECTRICAL CONNECTION.

GROUND CONNECTION.
The earthed apparatus must be permanently connected to the fixed electrical installation.
All exposed non-live metal parts of the unit that may accidentally become live must be electrically connected to the mains earthing conductor and to the earth connection of the pool structure, in accordance with the specification of the applicable National or Local Electrical Code. Use a copper conductor with a minimum section of 6mm² or AWG 13.

POWER SUPPLY.

DIN Standard 4844-W8
DANGER
This unit is supplied with power cables used for factory testing connected to its connection terminals. These cables must be removed in order to connect the power supply.

Never connect the power supply using the factory testing cables.

The unit must be permanently connected to the fixed electrical installation.
Ensure that no other equipment is connected to the same circuit.

The types and sections of power cables must comply with the specifications of the applicable Local or National Electrical Code. See chapter 10. You must select cables that are designed to withstand at least the current absorbed by the unit (see nameplate). Cables must be connected to the unit’s terminals blocks using the appropriate terminals.

The conductors must enter and exit the unit’s connection box through a cable gland, providing a watertight seal to prevent the ingress of water and dirt.

On three phase units, care must be taken to correctly position the motor winding connections.

Check the motor rotation direction before connecting the pump to the installation and before making the final connection to the mains power supply.

To change the rotation direction on three-phase motors, swap the position of two of the motor’s power supply cables.

6. PUMP HYDRAULIC REQUIREMENTS

WARNING The suction of the pump is dangerous and can trap and even drown swimmers. Never use or allow anyone else to use a pool, spa or water feature unless there are at least two inputs on each pump intake line. Never use or operate pools, spas or water features if the grills on intakes are broken or missing.
Follow the instructions listed below to minimise risks.

6.1 PROTECTION AGAINST ENTRAPMENT.

The pool’s suction system must provide protection against the risk of hair entrapment or suction.

6.2 COVERS/GRILLES ON INTAKE POINTS.

All intake points must have covers/grilles in a good state of repair. Covers/grills must be replaced if cracked, broken or missing.

6.3 PUMP INTAKE POINTS.

There must be at least two balanced main drains with grilles for each pump intake line, with a minimum separation of 1m (3 feet) between the centres of the main drain.
The system must be built in such a way that it cannot function if water flows to the pump from just one sump (there must be at least two main drain connected to the pump whenever it is operating).
In any case, if two main drain are connected to an individual intake line, that line must be equipped with a valve that allows the flow of water to the pump from both main drains to be shut-off.

6.4 WATER SPEED AND FLOW.

The maximum water speed must be less than or equal to 1.2 m/s (4 feet per second) unless the intake flow complies with the latest specifications indicated in the regulations of each country, region or community regarding the use of suction systems in swimming pools, spas or water features.

If 100% of the pump’s water flow comes from the main drain system, the maximum water speed in the suction system should be 1.2 m/s (4 feet per second) at all times, even if one of the main drains is completely blocked. The water flow in the other remaining drain(s) must comply with the latest specifications indicated in the regulations of each country, region or community regarding the use of suction systems in swimming pools, spas or water features.

6.5 PIPE INSTALLATION.

The pipe system must have at least the same section as the pump connections, i.e. ø75 or 2-½”.
To prevent stresses on the body of the pump, the installation, pipes and associated connection elements, pipes must be correctly aligned with the pump without using force, whilst attempting to ensure that both the intake and discharge pipes are secured independently as close to the pump as possible.

To prevent stresses on the installation due to small differences on the final connection of the installation pipes, we recommend starting the installation at the pump.

INTAKE.

Cavitation may occur if the pump’s intake becomes obstructed, causing damage to the internal elements of the pump. Keep the intake pipe clear of debris, solid residue and dirt.

All pipe systems containing water must be equipped with valves to prevent flooding during pump maintenance.

Never use a pipe with a diameter of less than ø75 (2-½”).
User larger pipes whenever needed to maintain the water speed below 1.2 m/s (4 feet per second).

The intake pipe must be one continuous run from its starting point to the pump. In order to prevent air pockets, the intake pipe must never be positioned higher than the water level or the level of the pump. Whenever reducers are required to connect the pump, we recommend the use of concentric reducers.

DISCHARGE.

In order to reduce load losses, we recommend the use of pipes of a larger diameter than the pump discharge and the use of as few connection elements as possible. Connection elements that may cause air pockets should not be used under any circumstances.
The diameter of the pipes used must be such that it ensures that the water speed remains below 2 m/s (7 feet per second).

7. COMMISSIONING

Before turning on the mains power to the pump unit, ensure that the electrical conditions are correct and manually check that the pump has not seized.

7.1 PUMP PRIMING.

Ensure that there is no pressure in the filter, pump or pipe system.
Never run the pump when dry. The water acts as a coolant for the mechanical seal. If the pump is operated when dry, the mechanical seal may be damaged, causing leaks, flooding and rendering the guarantee null and void.

WARNING

Re-filter to close the manual air output valve when the water flow is constant (there is no air) on the valve discharge. Failure to carry out this task may result in injury.
If the water level is above the level of the pump, ensure the cover is hermetically sealed and fill the pump by slowly opening the stop valve on the intake whilst keeping the discharge valve open.
If the water level is below the level of the pump, remove the pre-filter cover and fill with water up to the intake point. Replace the cover, ensuring it is sealed correctly.
Check that there are no leaks on the pump or the filter. If there are signs of leaks, DO NOT START THE PUMP.
Ensure that the motor turns freely. Never start the pump if the motor is blocked. The motors have a ridge at the end of the shaft in the fan area that allows users to manually check the motor rotation using a screwdriver.
(see Figure 1)
Start the motor for a few seconds, no more than 3, and check that the rotation direction matches the direction of the arrow shown on the fan cover. If this is not the case, advise an authorised service technician. To change the rotation direction on three-phase motors, swap the position of two of the motor’s power supply cables.
Check that the motor does not exceed the consumption level indicated on the motor rating plate.
If it does, adjust using the valve located on the pump discharge.

7.2 MAINTENANCE.

DIN Standard 4844-W8
Disconnect the power before performing any maintenance task on the pump.

Control and clean the pump basket on a regular basis. Close the intake and discharge valves. Remove the pre-filter cover and remove the basket. Never hit the basket to clean it, simply rinse it out under the tap. Replace the basket in its original position. Before replacing the seal on the pre-filter cover, check it and lubricate it with neutral Vaseline. Replace the pre-filter cover, ensuring a hermetic seal.
The transparent pre-filter cover must be cleaned with water and a neutral detergent.
Never use solvents. Do not place chemical products inside the pre-filter.
Remember, all changes to the position of the selector valve or the valve manifold of the filter must be made when the pump is stopped.
Remember to open the intake and discharge valves again before re-starting the pump.
The motor bearings are self-lubricating and therefore do not require lubrication.
The pump’s mechanical seal is lubricated with water from the pump itself. It does not require lubrication. The mechanical seal will need to be replaced occasionally due to wear or damage. Replace with HAYWARD original spare parts.

7.3 PRESERVATION.

DIN Standard 4844-W8
Disconnect the power before performing any maintenance task on the pump.

If the pump is not used for a long period of time, or there is a danger of freezing, empty the body of the pump by releasing the drain plugs equipped with O-rings. First check that the installation, pump, filter and pipes are not pressurised.
Before re-starting the pump, replace the drain plugs and their respective O-rings and prime the pump as described in point 7.1 of this manual. Keep the motor covered and dry while in storage.
To prevent issues of condensation or corrosion, do not cover or wrap the pump with plastic film or bags. Keep the pump in a dry place.
Do not start the motor if it has been affected by flood water. Notify a qualified technician to disassemble the motor and dry it out if possible.

Preservation of outdoor installations:

Empty the installation.
Dry as much as possible.
Lubricate seals with neutral Vaseline.
Re-assemble.
Leave drainage covers removed while the pump is not in use.

8. DISASSEMBLY / ASSEMBLY

8.1 DISASSEMBLY.

CAUTION
DIN Standard 4844-W8

Close all valves before performing any operation.

Disconnect the electrical installation (this must be carried out by an authorised installer).
Disconnect and release all the cables in the connection box.
Release the intake and discharge hoses.
Empty the pump by removing the drain plugs and their O-rings.

To disassemble and assemble the pump, see exploded view drawing. (POINT 12. EXPLODED VIEW DRAWING).

To separate the motor from the body, remove the 6 screws, then extract the motor unit together with the diffuser and the turbine.
In order to disarm the impeller remove the impeller cab and its O-ring (threated), using an 8 mm Allen wrench. This way the impeller gets released.

The moving part of the mechanical seal will also be released when this operation is carried out

8.2 ASSEMBLY.

ALL PARTS TO BE COUPLED DURING ASSEMBLY MUST BE CLEAN AND IN PERFECT CONDITION.

To assemble the pump:

Assemble the mechanical seal. Position the moving part of the seal on the shaft of the impellor, pressing it down until it fits into the seat. You must have lubricated the moving part of the mechanical seal with water beforehand.
Assemble the turbine on the motor shaft, using an anaerobic sealant to fix the metal parts in position and screwing it onto the shaft. This will connect the two tracks of the mechanical seal together.
Position the diffuser onto the connecting body, correctly lining up the fixing points. The diffuser can only be mounted onto the body in one position.
Position the O-rings on both the diffuser and the body.
Mount the motor assembly on the pump body using 6 screws.
