Wilo-Economy MHIE
Wilo-Economy MHIE
This document provides installation and operating instructions for the Wilo-Economy MHIE pump, originally in French with translations available. It is crucial for proper use and must be accessible at the installation site, complying with safety standards at the time of publication.
The pump is designed for pumping clear liquids in building, agriculture, and industry, but not suitable for Abyssinian wells.
- Max operating pressure: 10 bar
- Max suction pressure: 6 bar
- Temperature range: -15°C to +110°C (EPDM) / -15°C to +90°C (Viton)
- Ambient temperature: max +40°C
- Sound pressure level: 0/+3 dB(A)
Technicians and operators must read safety instructions before installation. Key symbols indicate general danger, electrical voltage danger, and handling notes. Personnel must be qualified, and unauthorized modifications are prohibited.
Check for transport damage upon receipt. Store the pump in a dry place if installation is delayed. Handle carefully to maintain geometry and alignment.
- Components include strainer-foot valve, suction valve, discharge valve, non-return valve, etc.
- The pump is centrifugal, multistage, and not self-priming.
- Motor is a 3-phase asynchronous motor with a speed variator.
- Accessories like IF-Modules, by-pass kits, and protection kits are available separately.
Two standard installation types are described. The pump should be installed in an accessible, frost-protected location. Hydraulic connections must be sealed properly, and electric connections should be made by qualified electricians.
Ensure compliance with applicable regulations. The motor-converter's electric characteristics must match the mains supply. Use power cables conforming to standards and ensure proper grounding.
Details on terminal connections for mains supply and inputs/outputs are provided, including instructions for sensor input, external setpoint input, and control input connections.
Describes connection terminals for interface modules like PLR and LON, designed to be twist-proof when connected to the converter. Outlines inputs and outputs for constant pressure and P.I.D. control connections.
Emphasizes safety, warning of death danger due to hazardous contact voltage from converter capacitors. Advises waiting five minutes after disconnecting supply voltage before intervention, ensuring all connections are voltage-free and properly earthed.
Explains control laws for input signals in constant pressure and P.I.D. control modes, detailing sensor signal ranges and implications of broken cables. Covers input of external frequency control in speed control mode.
Describes control elements, including setting with an encoder and switches for operation and service modes. Outlines display structure, focusing on access lock importance to prevent unauthorized changes.
Provides detailed menu navigation, including easy and expert modes for parameter settings. Explains adjustments for speed control, constant pressure, and P.I.D. control, emphasizing skilled technicians during commissioning.
Recommends preliminary rinsing for hygiene before using the pump with potable water. Details filling and degassing procedures, warning about dangers of operating the pump dry and precautions with hot water.
Before starting the pump, ensure the discharge valve is open. The pump should not operate at zero flow for more than 10 minutes with cold water or more than 5 minutes if temperature exceeds 60°C. A minimum flow of 10% of the pump's nominal flow is recommended to prevent vapor lock.
Faults should be addressed by qualified personnel. The converter is equipped with relays for centralized control. The SBM relay can be configured in three states: available transfer, run transfer, and power on transfer. The SSM relay activates upon detecting defects, stopping the pump until manual intervention.
Switch off equipment before maintenance. The pump and motor bearings are lubricated for life and require no additional lubrication. In case of prolonged stoppage, drain the pump if no frost risk. Replacement frequencies depend on operating conditions, with indicative lifetimes provided for components.
Provides a detailed error table listing possible faults, their causes, and remedies. Errors include pump overload, under/over voltage, missing supply phase, and motor overheating. Each error has specific remedies and waiting times before reset.
Errors should only be acknowledged once remedied. Skilled technicians should handle defects, and if in doubt, contact the manufacturer. The system displays error pages, and errors must be manually acknowledged if the auto-reset timer is inactive.
Spare parts should be ordered through approved technicians or Wilo after-sales service. Only original spare parts should be used to ensure proper pump function.
Includes a declaration of conformity with various European directives and standards, ensuring compliance with safety and environmental regulations.

and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance. If hot or cold components on the product/the unit lead to hazards, local measures must be taken to guard them against touching. Guards protecting against touching moving components (such as the coupling) must not be removed whilst the product is in operation. Leakages (e.g. from the shaft seals) of hazardous fluids (which are explosive, toxic or hot) must be led away so...
