Frequently Asked Questions - Multipool Plus ESPA

What is the ESPA Multipool Plus booster used for?

The Multipool Plus is a multi-cellular booster designed to provide pressure to automatic hydraulic brushes (bottom cleaners) for pools. It compensates for insufficient pressure in the filtration circuit to ensure optimal movement of the cleaner on the bottom and walls.

What is the power of the Multipool Plus?

The ESPA Multipool Plus booster develops a nominal power of 0.75 kW (1 HP). It reaches a maximum flow rate of 5.5 m³/h for a maximum total manometric height of 54 m.

With which pool cleaners is it compatible?

The Multipool Plus is designed to work with the majority of hydraulic brush cleaners, regardless of brand. Its integrated valve and pressure gauge allow for pressure adjustment to meet the specific requirements of each cleaner model.

How to adjust the pressure of the Multipool Plus booster?

Operate the integrated adjustment valve while monitoring the incorporated pressure gauge. Adjust until you achieve the pressure recommended by your cleaner's manufacturer (usually between 1 and 3 bar). This adjustment is always done with the pump running.

My hydraulic cleaner is not moving correctly, what should I check?

First, check the pressure displayed on the booster's pressure gauge: it should match the recommended values for your cleaner. Then, check for the absence of air in the circuit, the condition of the pre-filters, and the cleaner hoses (ensure there are no kinks or blockages).

Can the Multipool Plus be used with saltwater or ozone-treated water?

Yes. The construction materials (polyamide and Noryl fiberglass reinforced, screws and seals in AISI 316 stainless steel) make the Multipool Plus compatible with chlorinated water, ozonated water, demineralized water, and seawater.

The booster won't start, what are the possible causes?

Check the electrical supply (230 V or 400 V depending on the model) and the condition of the protection circuit breaker. Ensure the pump is properly primed (no air in the body). In case of prior overheating, the thermal protector may have tripped: let it cool for a few minutes before restarting.

How to prime and purge air from the Multipool Plus?

Slightly loosen the purge screw on the pump body until water flows out without bubbles, then retighten. Never start the booster dry: this will quickly damage the mechanical seal and may harm the turbine.

The booster vibrates or heats abnormally, what should I do?

Excessive heating often indicates a dry run (lack of water) or clogging. Immediately stop the device, purge the air and check the water supply. Persistent vibrations may indicate bearing wear or a foreign object in the turbine: have the device inspected by a technician.

Where can I find spare parts for the ESPA Multipool Plus?

Replacement parts (turbine, mechanical seal, pump body) are available from specialized retailers such as Spareka or Fixpart. Provide the reference PP06290 for the single-phase model to get the appropriate parts.

DANGER Wams that failure to observe the precautions Risk of involves a risk of electric shock. electrocution

DANGER Warns that failure to observe the precautions-involves a risk of damage to persons and/or things.

WARNING Wams that failure to observe the precautions involves the risk of damaging the pump and/or the plant.

1 - General information

Please observe the following instructions to achieve the best pump performance possible and a trouble free installation.

These pumps are designed to operate with clean water, free from particles in suspension and with a maximum temperature of 35 degrees centigrade.

WARNING. Correct pump operation is assured by following the instructions on installation and use.

DANGER. Failure to adhere to the instructions can result in premature failure of the pump and voiding of the warranty.

DANGER. Risk of electric shock. The pump must not be used in a pool when people are swimming.

2. Installation

2.1 - Fixing

The pump should be installed on a solid, horizontal base, secured by screws or bolts and using the existing holes in the mount (2 bolts/screws of 8 mm. ∅)

2.2 - Suction pipe assembly

The suction pipe, if longer than 7 meters, must be of the same or greater diameter than the pump inlet and installed in an upward inclination to prevent trapped air pockets forming.

The pump suction pipe should always be connected to the filter outlet. (See installation diagram).

2.3 Discharge pipe assembly

It is recommended to use pipes with a diameter equal or greater than the pump outlet. This will reduce loss of head caused by friction in longer pipe runs.

Pipework must be supported and not rest on the pump.

If a foot valve has not been installed it is recommended to fit a check valve to prevent accidental draining down of the system.

2.4 Electrical connection

The electrical installation must have a multi pole isolator with minimum 3 mm contact openings protected by a 30 ma. residual current detector (earth leakage trip).

Single phase motors have built-in thermal protection.

If the pump is not equipped with electric cable, an electrical engineer or a qualified technician must assemble this and it must also be of the type H07RN-F. Follow the instructions given on Fig. 1 for a correct electrical connection.

2.5 Pre-start checks

Ensure the voltage and frequency of the supply correspond to the values indicated on the electrical data label.

Ensure that the pump shaft is rotating freely.

Fill the pump body with water through the self priming plug opening. If a foot valve has been installed, also fill the suction pipe.

Check all joints and connections for leaks.

THIS PUMP MUST NEVER BE DRY RUN.

3. Programming (Multipool Tronic)

3.8 - Unblocking the fault condition

To exit from the fault condition, press OK for more than 2 seconds. If the appliance is in automatic mode and the stop time arrives, the fault condition disappears.

In fault condition the circuit will try to start up again after 15 minutes; if it is not successful, further attempts will be made at 30 minutes, 45 minutes and 1 hour after the previous attempt. After this, no further attempts will be made.

4. Starting

Ensure all valves in the pipework are open.

Connect power supply. There will be a delay before water appears at the end of the discharge pipe.

If the pump fails to operate refer to the possible faults, causes and solutions list for assistance.

For the pump to work correctly, it is essential that the filter unit (recirculating pump) is also running.

5. Maintenance

Under normal conditions these pumps require no special or planned maintenance.

If the pump is not to be operated for a long period it is recommended to remove it from the installation, drain down and store in a dry, well ventilated place.

ATTENTION: In the event of faults or damage occurring to the pump, repairs should only be carried out by an authorised service agent. When the pump is eventually disposed of, please note that it contains no toxic or polluting material. All main components are material identified to allow selective disposal.

When the valve is turned towards "-" it closes, less water passes through and a lower flow reaches the bottom-cleaner. At the same time, the pressure inside the pump body increases and the pressure gauge shows higher pressure = lower flow.

The opposite happens when the valve is turned in the direction of “+”: greater flow reaches the bottom-cleaner, the pressure inside the pump body decreases and the pressure gauge shows less pressure = greater flow. The output flow has to be regulated (using the valve) to the speed required by the cleaning robot. The pressure gauge mark allows the operating point to be memorised.
