Before connecting any piping, the plastic thread
protector installed in the connection port must be
removed. We recommend that the main vacuum
line to the receiver should not be reduced below
that provided on the receiver. Long piping runs may
need to be increased in size to minimize pressure
drop. Improper line sizing may result in a loss of
capacity. Ideally, piping should be constructed
using long radius elbows and a minimum number
of turns.
All secondary lines should be taken from the top or
side of the main line to prevent any accumulated
moisture from draining towards the pumps. All
lines should slope away from the pumps. Any low
points in the piping should be equipped with pipe
drains to remove accumulated moisture.
All intake vacuum lines must be piped in
accordance with NFPA 99. All pipe must be
either seamless copper tubing or other corrosion-
resistant metallic tubing, as detailed in NFPA 99.
