Frequently Asked Questions - ProMax Pressure Well 3000/18 OASE

How to install the pump in a well or borehole?

Attach a double-knot fixing cable to the pump ring, then lower it into the well. Keep the suction strainer at least 150 mm below the water level and 1.5 m from the bottom. For depths >5 m, tie the power cable to the fixing cable every 5 m to avoid strain.

What pipe diameter to use for discharge?

The recommended inner diameter is 25 mm (1 inch) for optimal flow. You can use a quick coupler for easier connection.

The pump does not start, what should I do?

First check the power supply: fuse, plug and cable. If all is correct, the motor may be overheated (thermal protection). Wait for cooling and clean the suction opening. Also ensure the well is not dry.

Why does the pump stop after a few minutes?

This is often due to overheating: the safety device has cut the power. Clean the suction opening and let the pump cool down. If the problem persists, check that the well contains enough water.

How to clean the check valve?

Disconnect the discharge pipe and adapter. Carefully remove the check valve with pliers, rinse it with clear water, then reassemble. If sand blocks the valve, clean it thoroughly.

Can I use the pump with salt water or for drinking water?

No, the pump is not compatible with salt water and is not suitable for drinking water. It is designed only for clear water or rainwater.

How to protect the pump in winter?

The pump is not frost-resistant. Before frost, drain it completely, clean it thoroughly, inspect for damage, and store it dry and frost-free. Protect the plugs from moisture.

What are the wear parts and how to replace them?

The main wear part is the operating unit (impeller). Its replacement is exclusively reserved for Oase service. Contact authorized after-sales service.

How does automatic mode work?

Automatic mode requires the Oase ProMax Garden Automatic Switch (model 44538). When you open a tap, the pump starts; when you close it, it stops automatically.

What to do if there is sand in the pumped water?

If the water contains a lot of sand (e.g. in a new well), run the pump at full capacity for about 1 hour to flush out the sand. Then clean the check valve and pump with clear water. Sand can block the impeller or valve.

Accessories

- OASE ProMax Garden Automatic Switch (44538) controls the pump during water withdrawal. The pump is switched on and off automatically.

Intended use

ProMax Pressure Well, referred to as "unit", may only be used as specified in the following:

• For pumping clear water or rain water.
• For irrigating and watering.
• For pumping the water out of water butts/rain barrels or cisterns.
• Operate in accordance with instructions. (→ Technical data)

Possible incorrect use

The following restrictions apply to the unit:

• Not suitable for salt water.
• Not suitable for drinking water.
- Do not use for long-term operation (e.g. continuous recirculation of the water in a pond).
- Do not use for commercial or industrial purposes.
- Do not use in conjunction with chemicals, foodstuff, easily flammable or explosive substances.
- Do not connect to the drinking water supply.

INSTALLATION AND CONNECTION

Connecting the pressure hose

An optimum flow rate is achieved with a hose inside diameter of 25 mm (1").

How to proceed:

□ B

1. Remove the protection cap.
2. Connect the pressure hose and adapter to the connection on the pressure side.
3. Recommendation: Use a quick-release coupling.

Installing the pump in a bored well or shaft

□C

• Attach the fixing rope with a double knot to the lugs and lower the pump into the bored well or shaft.
• Use the fixing rope to fix the pump at a height of at least 1.5 m above the bottom of the well or shaft.
• This prevents it from drawing in dirt particles.
• Ensure that the screen on the suction side is at least 150 mm below the surface of the water.
• Do not carry the pump by its power connection cable.
• From a well or shaft depth of 5 m, fix the power connection cable to the fixing rope at a distance of 5 m from the pump (strain relief).

OPERATION

The pump has no integrated switching on and off device. As soon as the pump is connected to the power supply, the pump starts up.

Automatic mode

The use of OASE ProMax Garden Automatic Switch allows automatic operation. When the connected appliance (water withdrawal) is opened, the pump switches on; when it is closed, the pump is switched off.

Starting up the pump

WARNING

Dangerous electrical voltage!

Death or severe injury from electrocution.

• Only connect the pump to the power supply when there are no persons in or reaching into the water.
• Before stepping into or reaching into the water, switch off all units located in the water.

- Insert the power plug into the socket. - The pump starts pumping.

NOTE

If the water contains a large quantity of suspended sand (e.g. in the case of a new well), allow the pump to run at full flow rate for approx. 1 hour without interruption in order to pump out the water containing the sand. Otherwise the non-return valve could become blocked by sand being deposited in the pressure line.

Taking the pump out of operation

• Disconnect the power plug.
• When the pump is switched off, residual water in the hose may flow back and out of the pump intake.

REMEDY OF FAULTS

WARNING

Dangerous electrical voltage!

Death or severe injury from electrocution.

Prior to starting work:

• Switch off the unit, disconnect the power plug and secure the unit from being switched on again.
• Before stepping into or reaching into the water, switch off all units located in the water.
  On completion of the work:
• Restore all the prerequisites for start-up.

Malfunction	Cause	Remedy
Pump does not start.	Power supply interrupted	Check the fuse and electrical plug connections.
Pump switches off after a short running period.	Overload protection has switched the pump off due to overheating.	Clean the intakeAllow the pump to cool down.
	The well has run dry.	Wait until there is sufficient water in the well.
The pump is running but is not delivering, or the delivered quantity is insufficient	Pressure hose blocked	Route the pressure hose without kinks.Check the outlet and clean if necessary
	Intake blocked	Clean the intake
	Air in the pressure hose	Expel the air from the pressure hose.
	If applicable:Non-return valve incorrectly fitted in the pressure hose or clogged	Correctly fit the non-return valve.Clean the non-return valve.
	The non-return valve is blocked with sand.	Clean the non-return valve. (→ Cleaning the non-return valve)If the pump still does not start up, contact OASE.
	Impeller defective or worn	Contact OASE.The impeller may only be replaced by the OASE Service.
	The impeller is clogged with sand.	Clean the non-return valve. (→ Cleaning the non-return valve)Flush the pump with sand-free water until all
		the sand has been completely flushed out. If the pump still does not start up, contact OASE.- The impeller may only be replaced by the OASE Service.

MAINTENANCE AND CLEANING

WARNING

Dangerous electrical voltage!

Death or severe injury from electrocution.

• Before reaching into the water, switch off the mains voltage of all units in the water.
• Isolate the unit (disconnect from the power supply) before carrying out any work on it.

NOTE

Recommendation on regular cleaning:

Cleaning the non-return valve

Sand can block the non-return valve of the pump so that it cannot close properly. The non-return valve has to be cleaned.

Prerequisite:

- The pressure hose and adapter have been dismantled.

How to proceed:

□D

1. Carefully pull out the non-return valve with pliers.

2. Thoroughly clean the non-return valve with clean water.

3. Reassemble in the reverse order.

4. Prior to installing, allow the pump to convey clear water for a few minutes (e.g. in a basin) to completely remove any sand residue. (→ Installation and connection)
