Manual cleaning magnetic dirt separator
© Copyright 2018 Caleffi
Operating principle
The manual cleaning dirt separator is used in central heating
systems to remove dirt and impurities from the circuit, progressively
and completely.
The device operates through the continuous action of special
filtering elements, located in a chamber through which the system
water flows. The very fine filter mesh progressively intercepts
particles down to 2 μm in diameter. At the same time, ferrous
particles are separated out by magnets on the surface of the filter
element.
Cleaning of the filtering elements takes place mechanically, with
manual action, by means of the handwheel provided and washing
with pressurised mains water while the filtering elements rotate.

For efficient washing, domestic hot water circuit pressure of between 3 and 5 bar must be guaranteed and it is mandatory to install a backflow prevention system to protect the water mains from possible contamination.

Page 6: Intended Use
Intended use The device is intended for use exclusively in heating systems containing water or water+glycol solutions up to a concentration of 50%. The device can be used in systems with maximum temperature of the medium of 85°C and maximum pressure of 10 bar. The minimum operating temperature of the medium is 5°C. -

Unpacking instructions First open the cover and then the cardboard side, then remove the pallet with the strainer. Storage Do not overturn or tilt the package. Multiple packages can not be stacked. Do not place any weight on top of the packaging. Handling It is advisable to move the strainer using mechanical devices (lift truck, crane, bridge crane, etc.) of adequate capacity. - Page 8 The device must be installed according to the diagrams given in this manual. The dirt separator must be installed on the return circuit, to intercept any impurities already present in the circuit, particularly when it is first started, before they can reach the boiler. The drain system must be operated in way that it does not prevent normal operation, avoiding counter pressure and must not endanger persons or property.
