Suggested Tools and Supplies for Installation The following tools and supplies are suggested to make the installation easier: NOTE: If any parts are damaged, contact Antunes Filtration Technologies IMMEDIATELY at 1-800-2532991 (in the U.S. only) or 1-630-784-1000. • • • • • • Equipment Setup General When placing the unit into service, pay attention to the following guidelines: • Make sure power to the unit is off. • Do not immerse cord or plug in water. • Keep cord away from heated surfaces. Screwdriver Drill with bits Strap wrench (up to 6” diameter) Tape measure Two gallon bucket Fresh 5 1/4% liq- uid chlorine bleach • • • • Adjustable wrenches Pipe wrenches Level Pipe dope or thread seal tape Caution This equipment is to be installed to comply with the basic plumbing code of the Building Officials and Code Administrators, Inc. (BOCA) and the Food Service Sanitation Manual of the Food and Drug Administration (FDA). Electrical Ensure that the line voltage corresponds to the stated voltage on the units specification label. Make sure that the plug on the power cord from the system and the outlet match. For proper operation, and to ensure the highest quality water from the system, make sure that the system is not connected to a switched electrical outlet. Caution Water pressure must not exceed a membrane burst pressure of 7 bar (100 psi). To reduce water pressure, install a water pressure regulator and set water pressure to suit application. Note that the trans membrane pressure must be .5 - 2.5 bar (7 - 36 psi). Plumbing NOTE: This unit is designed to use tap water not to exceed 104°F (40°C). The UF-420 and UF-440 systems use the following connections (Figure 1): Locating and Mounting the system • Water Inlet 3/4” NPT • Permeate (Product Water) 3/4” NPT • Drain 3/4” NPT When making a plumbing connection to the system, remember to use a back-up wrench on the supporting plumbing. Always use a good quality, approved, pipe sealant or thread seal tape on pipe threads. Be careful not to get the pipe sealant inside the pipe when making the connections. Consider these points before mounting the system: • Note the location of the water supply, drain, and an appropriate electrical outlet when choosing a mounting location. • Remember to allow for access to the timer/ programmer controls. • Do not mount the system above any electrical equipment, or above items that may be damaged if they get wet. Do not over-tighten the connections. It is recommended that plastic fittings be used when connecting to the 8 P/N 1010827 Rev. E 03/12 UF SERIES water filtration system A.J. Antunes & Co. Installation (continued) • Install the system in a location that will allow for future service access. 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 connection. 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 specification. • 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. 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 pressure, inlet pipe size, and system selected. It is recommended 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. 6 7/8" (17.5 cm) 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. 9 3/4" (24.8 cm) Figure 3. Mounting Bracket (Front View) 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. 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. 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. 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 container at the inlet water line and slowly open the inlet water valved. Allow the pipe to flush until all debris is removed. P/N 1010827 Rev. E 03/12 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. 9 UF SERIES water Filtration system A.J. Antunes & Co. Installation (continued) 1. Plug the power cord into the appropriate electrical outlet. The unit will power up and the LED display will display the following for about two seconds each: • • • Sanitizing the System and Lines The plumbing must be sanitized to eliminate possible contamination that may have occurred during the installation process. Chlorine bleach can be used to sanitize the plumbing. The amount of bleach used depends on the size of the system installed and the amount of plumbing downstream of the filter system. Generally, one ounce (30 ml) of bleach will be sufficient to sanitize the system. 8.8 F8 followed by its time settings in seconds Fi and its time setting in minutes or hours. The F8 and Fi sequence repeats for 30 seconds after which the unit automatically returns to the Flush Interval Mode (Fi). The time setting for Fi will be displayed and the decimal point will flash in one second intervals. 1. Make sure that the system has been flushed of air and debris as described in the Flushing and Starting up the System section of this manual. 2.Open the tap closest downstream to the filtration system and close the inlet water valve and allow the system to depressurize. Caution Ingesting the protective solution may cause irritation of the gastrointestinal tract, colic, diarrhea, or other similar symptoms 3. Place a bucket under the strainer at the inlet connection to the system. Open the strainer by unscrewing the cap. Water will flow out of the strainer as the system drains. 2.Open the tap or faucet closest downstream to the filter system. 3. Slowly open the inlet water valve and allow water to enter the system. 4. When the water flow from the strainer stops, pour the liquid bleach into the strainer. Be careful not to spill bleach onto clothing or skin. Re-attach the cap on the strainer. 4. Press and hold the Start button. After 6-7 seconds, the drain valve will open and FL will appear on the display. 5. Slowly open the inlet water valve and allow water to flow out of the tap until the smell of bleach is present. 5. Continue holding the Start button down for at least 30 seconds to keep the drain open. This flushes air out of the center of the hollow fibers of the cartridge filter. The drain will remain open as long as the Start button is pressed. Check to make sure that the drain water is directed into the drain without splashing. 6. Close the tap and let the system stand without water flow for at least 15 minutes to allow the bleach to sanitize the pipes. 7. After 15 minutes without water flow, open the tap and flush until the presence of bleach is gone. All other taps should be opened to flush any bleach from the plumbing. 6. Release the Start button. This closes the drain valve. Water should continue to flow through the system and out of the open tap. Allow water to flow out of the tap for at least 15 minutes at maximum flow rate. 8. Close the tap. The sanitization is complete. Program the timer following the procedure outlined in the Operation section of this manual. 7. Close the tap and let the system stand without water flow for 15 minutes to allow any trapped air to come out of the hollow fibers. Check for leaks at all fittings. O-Ring Strainer Screen 8.
