UF SERIES WATER FILTRATION SYSTEM

INSTALLATION (continued)

•Install the system in a location that will allow for future service access.

•Mount the system on a wall using appropriate mounting hardware.

•Remember to consider the operating weight of the system when choosing mounting hardware. Depending on the type of wall the system is being mounted to, wall reinforcement may be necessary.

Mount the filtration unit using the Mounting Bracket (Figure 3) using 1/4” by 1” bolts or bolts of the metric equivalent.

INLET WATER PLUMBING

It is recommended that the inlet water plumbing line be 3/4” NPT or larger. A shutoff valve (not supplied) should be installed in the line leading to the system.

The valve should be mounted close to the system inlet and sized properly for the inlet plumbing line. This valve will allow for easier servicing and future cartridge change-out. The system should only be connected to the cold water line.

To ensure that the highest quality water is produced from the system, the plumbing leading to the filter system must be flushed clear of all debris before the system is hooked up. Before making the connection to the inlet of the filter system, hold a bucket or other con- tainer at the inlet water line and slowly open the inlet water valved. Allow the pipe to flush until all debris is removed.

PERMEATE LINE PLUMBING

To ensure the highest quality and safest water, it is recommended that a check valve (to prevent backflow) is installed in the water line after the permeate connec- tion. This helps prevent possible contamination of the filter system due to other equipment downstream. The check valve (not supplied) should be mounted close to the system outlet and sized properly for the plumbing line. Check with local codes for the proper specifica- tion.

DRAIN LINE PLUMBING

The drain line is used to flush away the particle buildup when cleaning the filter. The drain line must be able to support the flow rate when the system flushes. The flow rate from the flush depends on the inlet water pres- sure, inlet pipe size, and system selected. It is recom- mended that the drain line be as large as, or larger than, the inlet plumbing line. The drain line should be as short as possible, sloping downward without kinks or loops. Be sure that the drain used is not blocked or restricted.

The filter system must be protected from possible back contamination by the installation of an air gap between the drain connection of the system and the drain (Figure 4). This gap in the line, with no physical contact between the system and sewer, prevents contamination of the system in the event of a backed-up sewer.

NOTE: Make sure that the end of the drain line is positioned and secured at least 2 inches above the drain so that the water flow is directed into the drain, without splashing.

FLUSHING AND STARTING THE SYSTEM

To ensure that the highest quality water is produced from the system, the plumbing leading from the filter system must be flushed clear of all debris after the system is hooked up. After making the connection to the outlet of the filter system, open a faucet or tap closest to the filter system, then slowly open the inlet water valve. Allow the pipe to flush until all debris is removed.

The unit also must be flushed to remove air and the shipping/storage solution. For maximum quality, the permeate water produced during the flushing procedure must be discarded. Direct this permeate water to drain.
