1) Carefully remove the membrane element from the box, check the element on the brine seal position and direction is correct (brine seal opening direction must face the water inlet direction, see the membrane element performance specification information on the diagram, as shown in Figure 6-1).
2) Push the end of the membrane element without the brine seal from the inlet end of the pressure vessel in parallel until the element is exposed outside the inlet end of the pressure vessel for about 10 centimeters. Note that the element must always be installed from the inlet end of the pressure vessel, as shown in Figure 6-1.
3) The connection between the elements of the inner connector into the elements of the water production center tube, before installing the connector, can be in the connector "0" ring on the "0" ring to apply a small amount of silicone-based "0" ring lubricant (Dow Corning 111 can be used, special can not be used) Exceptions to this rule are those that cannot be used in specific applications. The Dow Chemical Company recommends the use of chemically pure glycerin as the primary lubricant for couplings and
"0" rings, and glycerin is an FDA compliant chemical), or if unavailable, simply wet with a qualified pretreatment water.
4) carefully remove the second membrane element from the box, also check the element on the brine sealing ring position and orientation is correct, carefully hold the element and let the first element on the inner connector inserted into the center of the element water production tube, at this time can not let the connection of the inner connector can not withstand the weight of the element, parallel to the element will be pushed into the pressure vessel until the second element is exposed to the outside of the second element of about 10 cm, as shown in Figure 6-2, the second element will be inserted into the center of the element, and then the second membrane element will be pushed into the pressure vessel. As shown in Figure 6-2.
