Page 6: Flushing Schedule & Installation Instructions
Flushing Schedule & Installation Instructions Flushing Schedule The FreshPoint™ is flushed on a schedule dependent on the quality of water being treated. Default Factory Settings Flush Frequency: 100 gallons Flush Duration: 0.5 minutes Day Override: 1 Day These settings may need to be adjusted based on the analysis for the water treated and practical experience with fouling. -
Page 7: Installation Instructions
Installation Instructions Plumbing • The system and installation piping should be cleaned before the system is started so that no impurities, abrasive materials, or oily materials are washed into the membranes. The piping must be purged of air to prevent water hammer which can damage the system. •... - Page 8 Installation Instructions Standard Installation (Forward Flush only) A standard installation clears the membrane periodically by opening a drain port, and allowing the feed stream flow in its normal direction, but at a faster rate. The flow goes in and out of the end of the fiber instead of through the membrane, and the foulant is cleaned off the membrane and out of the unit to drain.
- Page 9 Installation Instructions Backflush Kit Installation Installations with high fouling potential will require plumbing in a pressurized surge tank and inlet solenoid valve (See Flushing Schedule Table 1). In the backflush mode, the filtered water from a pressure tank flows backward through the membrane from the filtrate side during the flushing cycle. This removes the foulant from the membrane surface as well as material that may have entered into the porous structure.

- Page 12 Installation Instructions Additional Water Treatment Devices • It is preferable to install the FreshPoint™ ahead of softeners and carbon filters, as the removal of particulates generally improves their performance. The FreshPoint™ should be installed after equipment such as iron filters, sediment filters, or multimedia filters.
- Page 13 Installation Instructions Outlet Fittings Apply thread sealant to the ¾” NPT thread of the adapter (Item 1) of the top end closure and securely thread the male half of the union (Item 9, Outlet Fitting Kit) to it. Apply thread sealant to both ends of the ¾” NPT nipple (Item 9, Outlet Fitting Kit), and securely thread it to the female portion of the union (Item 9, Outlet Fitting Kit) and the elbow (Item 9, Outlet Fitting Kit).
- Page 14 Installation Instructions Connect Fittings to the Vessel Connect the inlet end of the flow meter (Item 10) to the meter adapter which is threaded into the outlet elbow (Item 9), and secure it with the red clip. The flow direction is indicated on the body of the meter. Connect the drain valve union (Item 11) to the union at the sideport near the top of the vessel (Item 1).
- Page 15 Installation Instructions Meter/Solenoid Electrical Connection (Refer to Figure 5) Connect the drain solenoid wire harness to the solenoid valve. Insert the flow meter cable into the socket on the flow meter If installing with the backflush kit: a. Remove the two transformer leads from the terminal strip (terminals 4 and 5) and replace them with the leads from the higher-rated transformer provided in the kit.
- Page 16 Installation Instructions System Startup Guidelines Electrical Follow the instructions in the programming section of this service manual to setup the timer. Check the FreshPoint™ For Leaks • Ensure that all new plumbing connections, the three ports from the housing, and the two end cap perimeters have no leaks.
- Page 17 Installation Instructions System Sanitizing - With Prefilter Installed The unit should be sanitized/disinfected after the initial start up rinsing procedure, or in the case of biological fouling. The system should be disinfected after flushing but prior to use. Disinfect after the integrity test, if performed.
- Page 18 Installation Instructions System Sanitizing - No Prefilter Installed CAUTION: Sodium hypochlorite (bleach) is used for disinfection. The user should acquaint themselves with the appropriate safety precautions for storage and handling of the chemicals being used. USE ONLY SODIUM HYPOCHLORITE. DO NOT USE BLEACHES CONTAINING ANY OTHER COMPOUNDS. Close the inlet valve of the bypass plumbing arrangement.
- Page 19 Installation Instructions Membrane Integrity Test (Recommended) All membrane elements are factory-tested, and pass integrity tests before they are shipped. However, a full system integrity test should be done upon startup and then routinely (once per year minimum) thereafter. The integrity is used to check for: •...
- Page 20 Installation Instructions NOTE: Test the system first for plumbing leaks by closing the downstream faucet and/or connecting the outlet union, and performing steps 11 through 13. Pressure decay with outlet plumbing closed indicates a leak in the plumbing or valves, and the plumbing connections should be tightened or replaced and the system retested until the plumbing passes.
- Page 21 Installation Instructions Remove the Technician’s Decay Test Components. Repressurize the module with water by slowly opening the inlet valve of the bypass plumbing arrangement. Close the downstream faucet was opened for the test, or reconnect the outlet union, when air is no longer being expelled.
