Installation & Pump Connections - Stuart Turner MAINSBOOST iBOOST F200 Installation, Operation & Maintenance Instructions Manual

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
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. 8).
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. 4) 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.
