3. Remove the lock-open pin (10) from the pin
retainer hole in the spring cham ber (2). (See
Figure 2.)
4. System internal pressure must be at/near 0
psig (0 Barg). This will ensure plug (17) is fully
open. NOTE: Do not change range spring
(7) setting by rotating nut or handle (6).
5. Insert pin (10), jostle nut or handle (6) lift up
or push down to secure pin (10) thru ad just ing

SECTION VII
VII. CLEANING PROCEDURE
NOTE: CIP is limited to 50 psig (3.45 Barg) maxi-
mum cleaning solution pres sure at 300°F (149°C).
SIP is recommended to 20 psig (1.38 Barg) sat u-
rat ed steam pressure; can withstand 30 psig (2.07
Barg), but may reduce elastomer life expectancy.
C. Post-Sanitation:
1. Prior to system start-up, remove the lock-
open pin (10) from the adjusting screw (5)
and insert it into the pin retainer hole. Unit
