Frequently Asked Questions - DRAIN 100M ESPA

What to do if the pump does not start?

First check the power supply: fuses and residual current circuit breaker. If the problem persists, the thermal protection may have tripped; wait for cooling or check voltage. In case of hydraulic blockage, contact an ESPA approved technical service.

The motor runs but water does not come out, why?

Possible causes: discharge hose not connected, air pocket in pump body (shake laterally to evacuate), check valve reversed, or suction filter clogged. Clean the filter and check connections.

The pump starts and stops continuously, what to do?

This is often due to a blocked or poorly positioned level float. Ensure the float can move freely. Also check that the pump is sufficiently immersed and the water level is adequate.

How to clean the filter of the DRAIN 100M pump?

First unplug the pump. Remove the suction filter located under the pump. Clean it with clear water to remove debris. Reinstall before reusing the pump.

What is the maximum water temperature for this pump?

The maximum liquid temperature is 35 °C. Do not use with hotter liquids, as this could damage the motor.

Can I use the pump for a pool with bathers?

No, the pump must not be used in a pool when people are present. It is designed for draining and lifting, not for continuous filtration with swimming.

How to correctly install the pump in a tank?

Place the pump on a flat surface, at least 5 cm from the bottom if there are impurities. Ensure free space around the float. Never support the pump by the electric cable or hose; use a rope attached to the handle.

What to do in case of frost?

Drain water from pipes and pump before frost periods. If the pump remains unused for a long time, clean it and store it in a dry, ventilated place protected from frost.

Is the pump repairable?

Yes, but any intervention must be carried out by an ESPA approved technical service. Do not disassemble the pump yourself, this would void the warranty and could be dangerous.

What is the meaning of the symbols on the pump?

The symbols indicate safety instructions: dangerous voltage (risk of electric shock), mandatory grounding, do not carry by cable, etc. Consult the manual for full details.

Safety precautions

This symbol together with one of the following words “Danger” or “Warning” indicates the risk level deriving from failure to observe the prescribed safety precautions:

DANGER

risk of electric shock

DANGER

WARNING

Warns that failure to observe the pre cautions involves a risk of electric shock.

Warns that failure to observe the pre cautions involves a risk of damage to persons and/or things.

Warns that failure to observe the pre cautions involves the risk of damaging the pump and/or the facility.

Do not put your hand or any object into the suction or discharge mouth, since the rotating impeller could cause serious injury or damage.

1. GENERAL INFORMATION

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

Read these instructions before installing the pump. Save them for future reference.

DRAIN series have been designed for the drainage of infiltration water, empty water tanks or swimming pools. DRAINEX series are used for the drainage of sewage water with particles in suspension, septic tanks, etc. The maximum water temperature is 35^ C. Passage of particles up to 35mm.

All pumps have been manufactured in top quality material, submitted to strict hydraulic and electric controls.

Correct pump operation is assured providing the instructions on electrical connection, installation and use are strictly adhered to.

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

The pump cannot be used in a swimming-pool while there are people bathing.

2. HANDLING

The pumps are supplied suitably packaged to prevent damage in transit. Before unpacking, check that the packaging has not been damaged or deformed,

Lift and handle the product with care and with the right tools.

3. INSTALLATION

3.1. Fixing

The pump must always be totally submerged which will provide it with the necessary cooling. If there is a lot of dirt at the bottom of the water tank, and you are using a DRAIN pump, it is important to install the pump at least 5cm away from the bottom to avoid dirt blocking the wet end.

Ensure there is enough space for the free operation of the float switch (fig.3).

The pump must never be supported by the electric cable or the discharge line, if it is necessary that the pump does not touch the bottom, suspend it by a plastic cable fixed to the transport handle.

3.2. Discharge pipe assembly

In cases in which the discharge run is lengthy or sinuous, we recommend using lines with a larger diameter than the discharge mouth, to avoid head loss due to friction as much as possible and to obtain the best hydraulic performance possible.

Install a check valve to the outlet of the pump and you will prevent pipe from emptying each time pump stops.

Ensure that the pipe is not bent and that is correctly secured to the outlet connection because, in addition to preventing the desired flow, proper pump operation will be hindered.

3.3. Electrical connection

The electrical installation must have an effective earth and comply with the national regulations in force.

The protection of the system will be based on a differential switch ( fn = 30mA ) in addition to a multi-pole isolator with a minimum 3mm contact openings,

Pumps assembled with a starting control box or fitted with a capacitor are supplied ready for operation.

In the case of three-phase pumps the user must provide the protection system.

3.4. Pre-start checks

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

Ensure that the pump is submerged as shown in Fig.3.

THIS PUMP MUST NEVER BE DRY RUN.

NEVER MODIFY THE FLOAT SWITCH POSITION, WHICH IS ADJUSTED BY THE MANUFACTURER.

4. STARTING

If there is a line valve, open it completely.

Connect the electrical panel plug into a socket. If there is an appropriate level of water, the motor will immediately start up.

Check that the absorbed current is the same as marked on the nameplate.

If the motor does not start or no water flows at the end of the line, try to find the anomaly using the troubleshooting guide in point 8.

In the case of three-phase pumps check that the turning direction corresponds to the direction marked by the arrow situated in the suction cone.

5. MAINTENANCE

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

During frosty periods, remember to drain the line.

If the pump is not going to be operated for a long period of time, it is recommended to remove the tank, clean it and store it in a dry, well ventilated place.

ATTENTION: In the event of faults or damage occurring to the pump, repairs or electric cable replacement should only be carried out by an authorised service agent.

The Official Technical Services list is in www.espa.com.

6. DISPOSING OF THE PRODUCT

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.

This product or parts of it must be disposed of in an environmentally sound way, use the waste collection service. If this is not possible, contact the nearest ESPA service workshop.
