Otto Cool A2 Wall-Mounted Ultra-Quiet AC Condensate Pump (40L/h)

Specially designed to drain the condensate from larger-capacity split air conditioners and floor-standing units, the Otto Cool A2 Condensate Pump is one of the most reliable solutions for professionals in the field thanks to its high discharge power. Despite its high capacity, this model retains ultra-quiet DC motor technology and offers a flawless, quiet user experience for large air conditioners in offices, meeting rooms or spacious living areas.

High Discharge Capacity and Precise Sensor Technology

Operating with a discharge capacity of 40 liters per hour (40L/h), the A2 model easily removes the heavy condensate of air conditioners up to 45,000 BTU/h (13kW). Its electrode (wired) water level sensor, which makes traditional float failures a thing of the past, measures the water level with millimetric precision, completely eliminating the risk of overflow and dripping. Just like the A1 model, the spirit level integrated into its rear housing lets you install it in perfect alignment within seconds without looking for an extra tool.

Installation and Maintenance Note for Technicians in the Field

Technician’s Note: In the drain lines of large floor-standing or cassette air conditioners such as 45,000 BTU units, water builds up very quickly. The A2’s high 40-liter pumping power can quickly pump this heavy flow up to a 12-meter vertical distance without letting it stand in the pipes. The built-in spirit level on the rear panel will speed up your work considerably. After installation, you can improve your service quality and the life of the device by reminding your customer that the water tank must be cleaned every 6 months (as also indicated on the device) to keep it working properly.
