Abstract

A connection assembly is disclosed for connecting a magnetic separator into a central heating system circuit, the magnetic separator including a housing, a separation chamber within the housing, and externally threaded inlet and outlet ports extending from the housing. The connection assembly comprises: a fitment adapted to be received within at least one of the ports of the separator, the fitment including a bore for carrying fluid from/to the central heating circuit to/from the separator; a threaded connector disposed around the bore for securing the fitment to the or each port, the threaded connector having a hand grip area for facilitating tightening of the connector by hand; and a removable force transfer element receivable between the fitment and the threaded connector for transferring force between the threaded connector and the fitment.

Claims

1. A magnetic water cleaning device for use in a central heating system, the magnetic water cleaning device comprising a magnetic assembly and a sleeve around the magnetic assembly, in which the sleeve comprises first and second sleeve members, and a connection for connecting respective first ends of the first and second sleeve members together, and wherein the magnetic assembly is disposed within the sleeve, a first portion of the magnetic assembly being disposed in the first sleeve member and a second portion of the magnetic assembly being disposed within the second sleeve member, wherein a roof and a tubular wall depending therefrom extend from a second end of each of the first and second sleeve members.

2. The magnetic water cleaning device of claim 1, wherein the first and second sleeve members are assembled as a two-part sleeve which is substantially sealed around the magnetic assembly against ingress of magnetic particles.

3. The magnetic water cleaning device of claim 1, wherein the first and second sleeve members are identical in shape.

4. The magnetic water cleaning device of claim 1, wherein the connection includes at least one resilient latch member on the first sleeve member and a co-operating recess on the second sleeve member, and at least one resilient latch member on the second sleeve member and a co-operating recess on the first sleeve member.

5. The magnetic water cleaning device of claim 1, wherein the connection includes two opposing resilient latch members and two opposing recesses on the first sleeve member, and two opposing resilient latch members and two opposing recesses on the second sleeve member, the latch members of the first sleeve member co-operating with the recesses of the second sleeve member and vice versa.

6. The magnetic water cleaning device of claim 1, wherein at least one of the roofs is substantially conical.

7. The magnetic water cleaning device of claim 1, wherein a circular tray is adapted to connect with one of the roofs, to form a chamber.

8. The magnetic water cleaning device of claim 7, wherein the tray has a plurality of upstands for slowing flow within the chamber.

9. The magnetic water cleaning device of claim 8, wherein apertures are provided in at least one of the roofs, and top ends of the upstands protrude through the apertures when the tray is attached.

10. The magnetic water cleaning device of claim 1, wherein the sleeve is substantially solid and forms a barrier to prevent both water and solid particles from contacting at least part of the magnetic assembly.

11. The magnetic water cleaning device of claim 1, wherein at least one wall of the sleeve substantially surrounds and is in contact with the magnetic assembly.
