General Safety Instructions
ROWPU piping and equipment can contain extremely height pressure during and after
operation. If this pressure is not relieved before performing maintenance, serious injury or death
may result. Be sure to open all drains and vents before performing maintenance.
The R O. pressure tube is heavy To prevent injury to personnel and damage to equipment,
use two people to replace R. O. pressure tube.
One pressure tube is shown, others are similar. Mark ends of pressure tubes to aid installation.
a. At both ends of all four R 0 pressure tubes (17), loosen four hose clamps (6) and remove flexible tube (5).
b. Remove U-shaped pipe sections (15) from R O pressure tubes (17) as follows:
(1) Remove two nuts (11), screws (8), clamp halves (10), and gasket (9).
