6 INSTALLATION
Step 1:
a) Remove the Mainsboost vessel from its packaging and check to ensure it is not
damaged.
b) Carefully turn the vessel on its side using the discarded packaging to protect it.
WARNING: depending on cylinder size this may require two
people to complete safely.
c) Once on its side screw the Mainsboost vessel connector provided in the
upsteam line-in kit into the tank elbow at the base using suitable thread seal
such as PTFE tape or liquid thread lock (see Fig. 10).
d) Cut a copper tail to the following minimum length, ensuring clearance of the
base.
Pipe length:
MBP 100VS = 210 mm MBP 200VS = 270 mm MBP 300VS = 270 mm
MBP 130VS = 210 mm MBP 250VS = 270 mm MBP 450VS = 340 mm
Then re-erect the cylinder.
e) Fit the isolating valve provided to the tail now protruding from the base of the
vessel.
f) Remove the pump and mounting plate from its packaging and position it on the
Mainsboost vessel, fixing in place using the correct size screw and washers
provided (see Figs. 14 & 15).
g) Ensure the floor is sufficiently strong enough to take the total weight of the unit
when full of water (see Technical Specification section). Take care when
manoeuvring the unit so as not to damage it.
