4 INSTALLATION & PUMP CONNECTIONS
4.11
Mains water connection to iBoost:
The iBoost is to be permanently
connected to the mains water supply using rigid pipe or suitably sized and rated
flexible hose to comply with current building and plumbing regulations.
The water tank fill valve has a G ½ male threaded fitting; a suitable 90
o
elbow
type fitting must be used. When tightening ensure the fill valve within the tank
is not rotated. If the valve is rotated it may not function correctly with the risk of
flooding.
Ensure there is a demountable joint in the pipe to allow the removal of the iBoost
if needed (see Fig. 7).
4.12
Water outlet pipework:
1. The pump has a G ¾ threaded connection to accept the supplied hose. The
hose is made water tight with a sealing washer on assembly, nip tight to 4
to 5 Nm for water tight seal.
(Do not overtighten)
. The supplied hose must
only be connected to 22 mm pipework.
Ensure the pipe is free from all score marks and deformities in the area of the
insertion depth (Fig. 3) and cut the pipe square removing all burrs and sharp
edges to prevent damage to the sealing ‘O’-ring.
2. Prior to inserting the pipe into the fitting mark the insertion depth on the wall
of the pipe with a soft pencil at a distance of 33 mm from the end to be
inserted.
3. Check in the mouth of the fitting that the ‘O’-ring, nylon washer and collet are
in position.
