Frequently Asked Questions - Drainex 100 ESPA

What is the maximum water temperature the Drainex 100 pump can withstand?

The maximum water temperature is 35 °C. Above that, the pump could be damaged.

Can the Drainex 100 pump be used in a pool with swimmers?

No, the pump must not be used in a pool when there are people swimming, in accordance with safety instructions.

How to install the pump to avoid air pocket formation?

If an air pocket forms in the pump body, shake the pump sideways to release the air. Also ensure the pump is fully submerged.

What to do if the pump does not start?

First check the power supply (fuses, residual current device). If the thermal protection has tripped, reset it or check the voltage. Ensure the water level is sufficient and that the float is not blocked.

What type of electrical protection is recommended?

It is recommended to install a high-sensitivity residual current device (30 mA) and an omnipolar switch with a contact opening distance of at least 3 mm. Earthing is mandatory.

Can the pump run dry?

No, the pump must never run dry. This would irreparably damage the hydraulic part and the motor. The pump must always be submerged.

How to maintain the pump in winter?

During freezing periods, drain the water from the pipes to prevent ice formation. If the pump remains inactive for a long time, remove it from the tank, clean it and store it in a dry, ventilated place.

What to do if the pump starts and stops continuously?

Possible causes: blocked level float, thermal protection activation, or insufficient water level. Check the free movement of the float and wait for the tank to fill.

What is the maximum immersion depth of the pump?

The maximum immersion depth is 8.5 meters. Beyond that, the pressure could damage the seals.

How to dispose of the pump at end of life?

The pump contains no toxic materials. Take it to a waste collection point or hand it over to an ESPA approved repairer for proper recycling.

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.
