Product Description

Grundfos CONLIFT1 LS Condensate Pump

Part Number: 98452219

The Grundfos CONLIFT1 LS condensate pump collects and removes condensate when gravity drainage is not possible. It provides a practical solution for condensing boilers, air-conditioning systems, refrigeration equipment, humidifiers and dehumidifiers.

Condensate flows into the built-in tank. Then, the automatic float control starts the pump and moves the water to a suitable drain. As a result, installers can position an appliance below or away from the nearest waste connection.

• Non-return valve
• Floor-mounted or wall-mounted installation
• Compact design with easy cleaning access
• Grundfos product number: 98452219

Automatic Condensate Removal

The Grundfos CONLIFT1 LS receives condensate through its inlet connections. As the tank fills, an internal float starts the pump automatically. The pump then sends the condensate through the discharge pipe to a suitable waste connection.

Once the water level falls, the pump stops. Therefore, the unit runs only when needed and requires no manual switching during normal operation.

When Do You Need a Condensate Pump?

A condensate pump helps when an appliance cannot drain naturally into a nearby waste pipe. For example, the boiler may sit in a basement, utility room or cupboard below the available drain level.

The CONLIFT1 LS can also move condensate across a longer route where a continuous downward fall is difficult to achieve. However, installers must keep the pipe route within the pump’s stated performance limits.

Suitable Applications

• Domestic condensing gas boilers
• Condensing oil boilers
• Air-conditioning systems
• Cooling and refrigeration equipment
• Air dehumidifiers
• Humidifiers
• Evaporators
• Domestic and light-commercial installations

Important Condensate Compatibility

The CONLIFT1 LS suits condensate with a pH value within the range stated by Grundfos. Highly acidic condensate may require neutralisation or a different pump configuration.

Where the condensate has a pH below the permitted level, consider a compatible neutralisation unit or the Grundfos CONLIFT2 pH+ system. Always check the appliance instructions and test the condensate where necessary.

High-Water Safety Connection

The high-water switch provides extra protection if the water level rises beyond the normal operating range. In addition, the potential-free contact can connect to a compatible external alarm or appliance control circuit.

A qualified installer must complete any electrical safety connection. The final arrangement will depend on the boiler, alarm system and installation requirements.

Installation Guidance

Place the pump on a level surface or secure it to a suitable wall. Next, connect the appliance condensate outlet to one of the pump inlets and route the discharge pipe to an approved drain.

Keep the discharge pipe within the permitted head and flow limits. Also, protect the pipe from freezing, sharp bends and accidental damage.

The electrical supply and safety connections must follow the Grundfos instructions and current regulations. Therefore, a suitably qualified installer should fit and commission the pump.

Cleaning and Maintenance

Check the tank, float, inlet pipes and discharge route during routine appliance servicing. Remove any dirt or deposits that could affect the pump’s operation.

In addition, test the pump and high-water safety function according to the Grundfos instructions. Disconnect the electrical supply before opening or cleaning the unit.

Frequently Asked Questions

What does the Grundfos CONLIFT1 LS do?

It collects condensate from a compatible appliance and pumps it to a suitable drain when gravity drainage is not possible.

Can I use it with a condensing boiler?

Yes. The pump suits compatible condensing gas and oil boilers. However, you must check the condensate temperature, acidity and flow against the Grundfos specification.

Can it pump condensate uphill?

Yes. It has a maximum pumping head of 5.5 metres. The available flow will reduce as the required pumping height increases.

What is the maximum flow rate?

The maximum flow rate is approximately 600 litres per hour under suitable operating conditions.

What size is the collection tank?

The CONLIFT1 LS has a total tank volume of 2.65 litres.

Does the pump start automatically?

Yes. An internal float starts and stops the pump as the condensate level rises and falls.

Can I mount it on a wall?

Yes. You can install the unit on a suitable wall or place it on a level floor. Follow the Grundfos mounting instructions.

Can it handle acidic boiler condensate?

It can handle condensate within the permitted pH range. More acidic condensate may require a neutralisation accessory or a suitable CONLIFT2 pH+ system.

Does it have an overflow safety connection?

Yes. The pump includes a high-water switch with a potential-free contact for connection to a compatible alarm or appliance control circuit.

Who should install the pump?

A suitably qualified heating, plumbing or air-conditioning engineer should install and commission it according to the appliance and Grundfos instructions.
