greater than 50 psid (3,4 bar). To avoid high surges which can either
ruin the element or momentarily allow downstream contamination,
use a slow-opening type valve.
MAINTENANCE
1. The element operates effectively when it is saturated. The element’s
useful life will end only when the DP2 Differential Pressure Indicator
is completely red. The element cannot be cleaned or reused and must
be replaced at the end of its useful life.
2. IF THE UNIT HAS A MANUAL DRAIN, DRAIN THE UNIT ONCE
EVERY 8 HOURS MINIMUM. If the unit is equipped with an automatic
drain clean the screen around the drain. Clean screen by blowing off
with air gun.
3. When bowl becomes dirty, clean with a clean, dry cloth.
4. Before placing the unit in service, make sure that the bowl is
properly reinstalled, and securely bolted in place per noted torque
specification.
