closely to ensure that you do not loose pump prime, which may result in pump
damage.
6. Refer to the CIP cleaning procedure (Section 4.3.1) for cleaning steps.
WARNING: LOSS OF PRIME DURING SUCTION CLEANING MAY RESULT IN SERIOUS
DAMAGE TO THE PUMP.
NOTE: As previously mentioned, the manufacturer recommends use of a CIP or
booster pump to circulate the cleaning solution during membrane element cleaning.
7. After suction cleaning cycle is complete, reopen inlet water and flush machine

4.5. Changing Out Membrane Elements

CAUTION: Replacement membrane elements are shipped from the factory in a
plastic bag with a small amount of bactericide solution to prevent biological growth.
When installing the membrane elements, always provide adequate ventilation and
wear gloves while handling the membrane elements as recommended. The
membrane elements must be kept moist at all times in to prevent possible damage to
the membrane element material.
1. Remove the top end caps and clamps from the membrane element housings.
Lubricate all O-rings and brine seals, and the PVC membrane element stems
(stingers) with a non-petroleum based lubricate (i.e., glycerin or poly water).
2. Load the down flow membrane elements first, by inserting the membrane
element into the membrane element housing with the brine seal end of the
membrane element up. Slowly turn the membrane element as you lower it
into the membrane element housing. As you reach the bottom of the housing
slowly guide the PVC stem or stinger on the end of the membrane element
into the head of the end cap. As the membrane element slides into the
housing the brine seal will be on the top.
3. Next, load the up flow membrane elements, by lubricating all brine seals, O-
rings, and the membrane element stingers. With the up flow membrane
element and the brine seal will be on the bottom of the membrane element.
Turn the membrane element slowly as you lower it down into the housing. As
with the down flow membrane element, one must slowly guide the PVC
stinger on the end of the membrane element into the end cap.
