Frequently Asked Questions - GP1200 Cotech

The pump does not start. What could be wrong?

First, ensure the power supply is connected and the RCD has not tripped. Check fuses. If the overload protection has tripped, reset it. Also verify that the inlet water pressure is not too high, and clean any dirt or deposits blocking the pump. If the thermal protection has activated, unplug and let the pump cool down.

The pump runs but does not pump water.

This usually indicates air in the suction line. Open all valves and nozzles to let air escape. Ensure the suction hose is below the water level and not leaking. Check that the suction head does not exceed 8 metres and the pressure head does not exceed 50 metres. Tighten any loose connections.

Why is the pump delivering low capacity or low pressure?

Check that the suction head and pressure head are within limits (max 8 m and 50 m respectively). Ensure the suction hose is fully submerged and not above water. Remove any dirt or deposits from the pump. Also verify that the foot valve is clear.

The pump stops suddenly during operation.

This is likely due to the thermal overload protection tripping because the pump overheated. Unplug the pump, clean it, and allow it to cool down. Remember the maximum water temperature is 35 °C. Check for obstructions causing overheating.

The pump does not stop running.

A loose tap or leaking pipe prevents the system from reaching the cut-off pressure (2.8 bars). Inspect all connections and tighten or seal any leaks. If the problem persists, check the diaphragm and air pressure in the tank.

The pump starts and stops repeatedly.

Frequent cycling is caused by a leak in the system (tap or pipe) or low air pressure in the tank. Check and tighten connections. Measure tank air pressure at the valve (should be 1.5 bars). If the diaphragm is faulty, replace it.

How do I check the air pressure in the tank?

Use a standard vehicle air pressure gauge. Remove the plastic cap on the end of the tank to access the valve. The recommended air pressure is 1.5 bars. Adjust with a pump if needed.

Can I run the pump dry?

No, running the pump dry will cause rapid wear and voids the warranty. Always ensure the pump is filled with water before starting, and the suction hose remains submerged.

What liquids can be pumped with this unit?

Only clean water with a temperature not exceeding 35 °C. Do not use with corrosive, flammable, or explosive substances (petrol, kerosene, thinners), fats, oils, saltwater, urine, or sewage.

How should I store the pump for winter?

Completely drain the pump and tank to prevent frost damage. Remove the drain plug and filler plug to empty all water. Store the pump in a dry, frost-free place. For long storage, periodically check that the rotor moves freely by briefly turning the pump on and off.

Safety

• Always use a residual current device (RCD or RCCB) which trips at < 30 mA between the pump and the power supply.
• Always inspect the pump before using it, especially the power lead and plug. Never use the pump if any of the parts is damaged.
• Make sure that the pump and all electrical connections (extension lead, RCD, etc) are placed in a dry place and protected from rain, moisture and overflows. The temperature should not exceed 35 °C.
• Do not expose the mains lead to extreme heat, oil or sharp edges.
• Keep children and animals away from the pump when it is running.
• Keep everyone out of the water (pool, etc.) which is being pumped.
• Only use the pump as described in this instruction manual.
• The operator of the pump is responsible for the safety of the pump and its applications.
  • Always unplug the pump before adjusting or repairing it.
• Do not expose the pump to jets of water.
• The pump should only be repaired by a qualified electrician using original parts.
• The pump must not be run dry, this voids the guarantee.
• The pump must only be used by those who have read the instruction manual. Keep children and animals away from the pump, especially if it is under pressure.

Note:

In addition to the pressure of the pump there is the pressure of the inflow water, the combined pressure in the tank must not exceed 10 bars.

Prevent water damage, think before it happens!

Leaking in pump and pipes may occur through frost damage, incorrect installation, pressure surges, etc. The pump should therefore be placed in a waterproof environment that your insurance company has approved in your insurance policy. Contact your insurance company if you are unsure.

Product Description

Operating Range

• Automatic irrigation of lawns, vegetable plot and gardens.
- Pumping water from springs, wells, water containers, etc.
- The booster pump is intended for pumping clean water.

Note:

The pump must not be used with corrosive, flammable or explosive substances (petrol, kerosene, thinners), fats, oils, saltwater, urine or toilet sewage water.

- The temperature of the liquid must not exceed 35 °C.

Parts

1. Suction Hose Connection
2. Pressure Hose Connection
3. Thermoswitch
4. Power Switch
5. Manometer
6. Tank
7. Pump
8. Drain Plug
9. Filler Plug

- Place the pump on a firm, hard surface, well protected from water spray.

Connecting to the Power Supply

- Connect the mains lead to a RCD protected earthed socket.

- The pump has a built-in thermal motor protection and automatically shuts off when it overheats (the motor starts again when it has cooled).

Connecting the Suction Hose

- Connect a 25 mm (1") spiral-reinforced high-pressure hose to the suction hose connection.

- The suction hose should be fitted with a foot valve/non-return valve.

- Place the suction hose so that it slopes upwards from the water to the pump inlet connection.

- The suction hose must always be on a lower level than the inlet to the pump. Air-pockets in the hose could disrupt the operation of the pump.

- Hoses or pipes must not be connected in such a way as to exert any pulling strain or tensile stress on the pump unit.

- Fit the foot valve at the end of the suction hose (pipe).

- The foot valve should be anchored to the bottom so that the pump does not run dry if the water level drops.

- The suction hose assembly must be air-tight to prevent air from being sucked into the pump.

- A filter should be fitted to suction the hose to prevent sand, mud, etc from being sucked into the pump.

Pressure Connection

- Connect a 19 mm (3/4") spiral-reinforced high-pressure hose to the outlet hose connection. Smaller hoses can reduce the suction power.

Starting the Pump

1. Place the pump on a firm, hard surface, well protected from water spray.
2. Connect the suction hose and the outlet pressure hose.
3. Connect the mains lead to an earthed socket which is protected by an RCD.
4. Fill the pump with water via the filler hole (9).
5. Connect the pressure hose to the hose connection (2).
6. Open all valves and the nozzle of the pressure hose from the pump so that any air can escape.
7. Start the pump. It can take from four to six minutes for the pump to reach maximum effect, depending on the pressure head, and amount of air on the suction side. Fill the pump with water via the filler hole (9) once more if the booster pump does not work satisfactorily after six minutes.
8. When the water starts to flow, let it run for a couple of minutes with the valves and nozzle open to get rid of all the air, then close the valves and nozzle.
9. The booster pump stops automatically when the pressure in the tank reaches 2.8 bars.
10. If the pressure falls to 1.4 bars, the pump will automatically start again to rebuilding the pressure to 2.8 bars.

Maintenance

• Always unplug the pump before carrying out any kind of maintenance.
- Use a soft lightly moistened cloth to clean the plastic parts of the pump. Never use solvents or strong detergents.
- If the pump is unused during the winter, both the pump and the tank should be emptied. Store the pump in a dry place.
- If there is a chance of frost the pump should be completely emptied.
- If the booster pump has not been run for a while it is a good idea to check that the rotor moves freely by quickly switching the pump on and off.

- Checking the air pressure in the tank

Use a vehicle air pressure gauge to measure the pressure in the tank. The air pressure is measured at the valve just inside the plastic cap on the end of the tank.

- The pump should be checked regularly. Check operation and inspect for any damage.

Useful Advice

• Dry running of the pump should be avoided because it increases wear.
• Pull the plug not the lead when unplugging the pump from the power supply.
• Never lift or carry the pump by its power lead.
• Sand and other abrasive substances in the pumped liquid will increase the wear and tear and reduce the capacity of the pump.
• Make sure that the recommended suction head (8 m) is not exceeded.
• Protect the pump from frost.
• The pump is designed for intermittent use, not continual operation such as for a fountain.
