6. Precautionary Notes
i)
Connection of balancing liquid piping whether to
suction casing or to the feed water tank is indicated
on the front page (Technical Data Sheet) of the order
acceptance. This is to be strictly adhered to.
ii)
Size of the balancing liquid piping should be exactly
as given in article 3 above.
iii) Whenever the balancing liquid line is fed back to
feed water tank, and if more than one pumps are
operating in parallel, the individual balancing liquid
lines should be independently connected to the feed
water tank, without joining them together, or even
putting them into a common header.
iv) The globe valve in the balancing liquid line back to
feed water tank should always remain in fully open
condition, and on no account should it be closed even
by accident.
v)
The piping for safety valve has to be branched prior
to the check valve, so that all the further piping is
safe guarded against the increase in pressure.
