The following tables provide the recommended wash pressures and times.

Table 1. Wash medium parameters for integral wash nozzles in PR-43-AP
Min. above process pressure Max. above process pressure Wash time Recovery Interval
Steam (SN) 2 bar (30 psi) 4 bar (60 psi) 3 s 20 ‑ 30 s 20 ‑ 30 min
Water (WN) 2 bar (30 psi) 4 bar (60 psi) 10 s 20 ‑ 30 s 10 ‑ 20 min
High pressure water (WP) 15 bar (220 psi) 40 bar (600 psi) 10 s 20 ‑ 30 s 10 ‑ 20 min
Table 2. Wash medium parameters for flow cell wash nozzle AFC
Min. above process pressure Max. above process pressure Wash time Recovery Interval
Steam (SN) 3 bar (45 psi) 6 bar (90 psi) 3 ‑ 5 s 20 ‑ 30 s 20 ‑ 30 min
Water (WN) 3 bar (45 psi) 6 bar (90 psi) 10 ‑ 15 s 20 ‑ 30 s 10 ‑ 20 min
High pressure water (WP) 25 bar (350 psi) 35 bar (500 psi) 10 ‑ 15 s 20 ‑ 30 s 10 ‑ 20 min
CAUTION In steam wash, do not exceed the recommended wash times, because some process media may burn to the prism surface if steamed for longer time. In case of coating, shorten the wash interval.
In water wash, water temperature should be above the process temperature.
The check valve pressure drop is 0.7 bar (10 psi).
