Fat Level Sensor KVF-F Safety Safety General safety instructions Responsibility for planning, assembly, commissioning, operation, maintenance, and dismounting lies with the system operator. Installation and commissioning of all devices must be performed by a trained professional only. Protection of operating personnel and the system is not ensured if the product is not used in accordance with its intended purpose.
ISO9001 Intended Use The fat level sensor KVF-F (referred to as "sensor" in the following sections) is a suspended sensor for monitoring fat layer thickness in grease interceptors. The sensor must always be connected to an warning device of type NVD-111 (see product program).
Fat Level Sensor KVF-F Safety Delivery, Transport and Storage Check the packaging and contents for damage. Check if you have received every item and if the items received are the ones you ordered. Keep the original packaging. Always store and transport the device in the original packaging.
Fat Level Sensor KVF-F Safety Disposal Disposal of devices and their packaging material must be performed in compliance with the applicable laws and guidelines of the corresponding country. The devices do not contain batteries which need to be disposed of separately from the products.
Fat Level Sensor KVF-F Product Specifications Product Specifications Function The sensor has an integrated electronic circuit which, via an oscillator circuit, emits a weak HF signal that changes depending on whether the sensor element is surrounded by water or fat.
Fat Level Sensor KVF-F Installation Installation Mounting of the Sensors Read the chapter on Safety and, in particular, the section on Installation and Commissioning (see chapter 1.6) before mounting the sensor. Do not remove the identification plate. Warning! Risk of short circuit Injuries and damage to the device are possible when working with live parts.

Fat Level Sensor KVF-F Installation The oil/petrol separator can be made of various materials. We therefore recommend using the following methods to secure the device in a suspended position: If mounting the device in concrete containers, use the NVO5-B mounting set.
Fat Level Sensor KVF-F Installation Mounting the KVF-F Fat Level Sensor The sensor must be immersed a few centimeters when the liquid is at its normal level (water zero line). The exact immersion depth depends on the type of grease interceptor,...

Fat Level Sensor KVF-F Installation Connection of the Sensor Read the chapter on Safety and, in particular, the section on Installation and Commissioning (see chapter 1.6) before connecting the sensor. Warning! Risk of short circuit Injuries and damage to the device are possible when working with live parts.
Fat Level Sensor KVF-F Operation Operation Emptying (Disposal) of the Container The sensor is a sensitive component. Therefore always observe the following safety information during emptying (disposal): Caution! Malfunction or damage through mechanical stress of the sensor. In case of nonobservance, the safety and operation of the sensor or the entire alarm system is not guaranteed.
Fat Level Sensor KVF-F Maintenance and Repair Maintenance and Repair Function Testing Test frequency The sensor is maintenance-free. However, to guarantee perfect operation of the complete alarm system check the operation of the sensor at least once a year, or more frequently in the event of unfavorable environmental conditions.
Fat Level Sensor KVF-F Troubleshooting Troubleshooting Sensor Maintenance Caution! Malfunction or false alarm caused by a contaminated sensor If the sensor is very dirty, this may trigger a false alarm or mean that no alarm is triggered under certain circumstances.
