User Manual for Nilfisk FOOD MultiFoamer Inox

Quick guide from the manual

The MultiFoamer Inox is an industrial low-pressure cleaning and sanitizing station. Before use, ensure all operational staff have read the safety instructions. Always wear protective glasses and gloves when operating the unit. In case of emergency or maintenance, close the water and air supply and turn off the power.

Overview and use

The MultiFoamer is a complete hygiene and pumping station that supplies pressurized water to integrated hygiene points or connected cleaning areas. It requires a supply of water, power, compressed air, and detergents or disinfectants. The unit features a frequency-controlled pump for constant working pressure.

Installation

The unit must be mounted in frost-free rooms on a stable brick or concrete wall. Ensure the pipeline is rinsed thoroughly before connection. The unit is hung on a wall bracket and secured with two screws. Water connection must be made at the top of the unit, and a closing valve is recommended on the inlet. Electrical installation must include a separate service switch and an earth leakage circuit breaker (ELCB) with a 300 mA trip level.

Operation

To start the system, ensure water and air supplies are open. For air pressure adjustment, remove the cover and turn the reduction valve knob: clockwise to increase pressure, counter-clockwise to decrease. To stop, turn off the water and air supply, and deactivate the chemical supply by removing the User Pack or pulling up the suction hose. Always rinse the chemical supply system after use to prevent clogging.

Maintenance and service

Preventive maintenance should be performed by an authorized service engineer at least once a year. Regularly lubricate quick couplings with waterproof grease. The unit requires periodic deliming based on water hardness (see table in the manual). Internal cleaning of the unit is recommended once a year. Do not spray inside the unit.

Troubleshooting

If the unit does not start, check the supply voltage and the flow switch adjustment. If there is no pressure or low pressure, check the water supply, clean the filter, or check the pump. If foam creation is insufficient, check the air supply, adjust air pressure, or clean/replace the non-return valve for air.
