Hose to pump
The pump inlet and outlet ports have factory assembled fittings which are specifically
designed for connection to the G¾ female running nuts on the flexible hoses. The hose
end is fitted with a rubber sealing washer which is held captive within the nut assembly.
Locate the hose into position and screw the nut fully onto the fitting by hand. Finally nip
tight with a spanner (4/5 Nm) for a water tight seal (do not overtighten).

Hose to pipework
1. The hoses are fitted with plastic push-in connectors, which must only be connected
with the following:
a) 22 mm diameter copper pipe to BS EN 1057 - R250 (half hard) - Table 3.
b) 22 mm plastic pipe to BS 7291 part 1 and part 2 (Table 1), or part 3 (Table 1) plus
internal support sleeve*.
* The internal bore of the plastic pipe must be supported against collapse with the
pipe manufacturers recommended support sleeve (pipe insert).
c) Appropriate plumbing fittings that are compatible and will provide a water tight
connection.
Ensure the pipe is free from all score marks and deformities in the area of the
insertion depth (Fig. 7) and cut the pipe square removing all burrs and sharp
edges to prevent damage to the sealing 'O'-ring.

Note: When tightening or loosening the
hose nut assembly, the anti-rotation
flats provided on the inlet and outlet
fittings should be used for placement of
a second spanner as shown. This is to
prevent complete assembly rotation.
It may be necessary to partially rotate
the reed switch clamp assembly on the
outlet fitting to avoid damage during
placement of the second spanner.
