material) 6 product) and utility line) entering and lea:ing to and from the

plant unit concerned.

con)ideration.

a -n)tallation maintenance and tran)portation and e9uipment 6

machine) are ea)ily performed.

Piping etween unit) a) )hort a) po))ile.

c The numer and length of rack) are kept to minimum.

2 The following) are the typical rack layout).
