1 General Installation and operating instructions About this document The language of the original operating instructions is German. All other languages of these instructions are translations of the original operating instructions. These installation and operating instructions are an integral part of the product. They must be kept readily available at the place where the product is installed. Strict adherence to these instructions is a precondition for the proper use and correct operation of the product. These installation and operating instructions correspond to the relevant version of the...

Personnel qualifications The installation, operating and maintenance personnel must have the appropriate qualifications for this work. Area of responsibility, terms of reference and monitoring of the personnel are to be ensured by the operator. If the personnel are not in possession of the necessary knowledge, they are to be trained and instructed. This can be accomplished if necessary by the manufacturer of the product at the request of the operator. Danger in the event of non-observance of the safety instructions Non-observance of the safety instructions can result in risk of injury to...

Unauthorised modification and manufacture of spare parts Unauthorised modification and manufacture of spare parts will impair the safety of the product/personnel and is not permitted. This also applies to all installed plug and cable connections on the product. Non-observance results in a loss of any claims to damages and it will void the manufacturer's declarations regarding safety. Improper use The operating safety of the supplied product is only guaranteed for conventional use in accordance with Section 4 of the operating instructions. The limit values must on no account fall under or...

English CAUTION! Risk of injury and damage to property! Non-approved fluids can damage the pump and also cause injury. Comply strictly with the relevant safety data sheets and manufacturer's data! • 2) Observe the specifications of the manufacturer regarding the mixing ratios. • 2) Additives are to be mixed to the fluid on the pressure side of the pump, even if this is contrary to the recommendations of the additive manufacturer! CAUTION! Risk of property damage! When changing, refilling or replenishing the fluid with additives, there is a risk of material damage caused by enrichment of...

Function of the pump There is a control module (Fig. 1, item 5) in axial design on the motor housing, which controls the differential pressure of the pump to a setpoint within the control range. Depending on the control mode, the differential pressure follows different criteria. In all control modes, however, the pump adapts itself continuously to the changing power requirements of the unit, which is the case especially when thermostatic valves, zone valves or mixers are used. The basic advantages of the electronic control are: • Energy savings and hence reduction of the operating costs, •...

English • Once power returns after a power interruption, the pump goes back into operation with different start-up times, depending on the setting chosen. See chapter 10.2 for the restart times. • SSM: Faults always result in the activation of the collective fault signal (“SSM” via a relay). The contact of the collective fault signal (potential-free normally closed contact) can be connected to a building automation system. The internal contact is closed if the pump is without power, if there is no fault or if there is a malfunction of the control module. The performance of the SSM is...

English • The minimum ambient temperature should not fall below the freezing point of the fluid nor should it be lower than -10 °C. • The fluid and ambient temperature should not exceed or fall below the permissible values ??(see chapter 5.2). CAUTION! Risk of property damage! Provide adequate ventilation/heating in situations where the permitted ambient temperature is exceeded or fallen short of. • Carry out all welding and soldering work prior to the installation of the pump. CAUTION! Risk of property damage! Contamination from the pipe system can destroy the pump during operation. Before...

English 7.1.2 Insulation of the pump in cooling/air-conditioning systems The thermal insulation shells (Fig. 1, item 8) included in the scope of delivery may only be used in heating applications at fluid temperatures of +20°C or higher, since these thermal insulation shells do not enclose the pump housing in a diffusion-proof manner. The pumps of the Wilo-Yonos ECO BMS series are suitable for use in air-conditioning, cooling, geothermal energy and other similar systems with fluid temperatures down to -10°C. Condensate can form on parts that come into contact with the fluid, such as pipes...

English • The electrical connection must be established via a fixed power cable (3 x 1.5 mm2 minimum cross-section), equipped with a plug and socket connector or an all-pole switch with a minimum contact opening width of 3 mm. • The following minimum requirements are to be met if shutdown takes place by means of an on-site network relay: Rated current ≥ 8 A, rated voltage 250 VAC, Contact materials: AgSnO2 or Ag/Ni 90/10 • Fuse protection: 10/16 A, slow-blow or automatic fuse with C characteristic. • A motor protection switch supplied by the customer is not required. Nevertheless, if such a...
