General Information

Installation of UV System

CAUTION
Electronic controller must be connected to a Ground Fault Protected Circuit (GFCI) receptacle. Ensure green ground wire ring terminal is securely fastened to ground stud on UV chamber.

3.1 Installing UV System
The UV system is designed to be mounted either horizontally or vertically at the point-of-use or point-of-entry depending on the specific flow rate of the unit.
If installing the chamber in horizontal position the outlet port must be pointing upwards to ensure all air is fully purged from the chamber.

Note: The preferred installation is vertical with the lamp connector on top. This is to prevent water damage from occurring on the lamp pins and lamp connector. If horizontal install is required ensure inlet port is positioned facing downward.
Note: To reverse inlet port to suit installation plumbing see Section 3.1 procedure 4.
Prerequisites:

• Determine appropriate indoor location for the UV system. Refer to Figure 3.
• Ensure adequate clearance above chamber to allow for removal of the UV lamp unit.
• Make sure to turn off the main water supply and depressurize the line.
• Mount the system to the wall with appropriate lag bolts through the two mounting holes located on the metal bracket.
• The supplied lag bolts are suitable for attachment to wood. (Attachments to other materials will require purchasing of alternative hardware).
• Make all necessary plumbing connections. Refer to Figure 3.

Procedure:

1. Figure 3 shows the installation of a typical UV system and the related components that may be used for the installation.
   The use of a by-pass assembly is recommended in case the system requires “off- line” maintenance. In this case, note the system requires a supplementary disinfection for the distribution system if any water is used during by-pass condition. In addition, during by-pass, the water will NOT be disinfected and a “DO NOT CONSUME THE WATER” tag should be physically installed on the by-pass assembly until such time as the system is sanitized and returned to service. For more information, refer to Section 3.2. If the water is to be consumed while the system is off-line, the water must be boiled for twenty minutes prior to consumption.

   |
   A| 6” Note: By-pass pipe should be at least 6” above the Arros UV unit and as close to the wall as possible to ensure lamp can be removed.
2. Select a suitable location for the UV system and its related components. As it is recommended to install a GFCI, make sure that this is taken into consideration prior to any installation. The system can either be installed vertically as shown in Figure 4 A, or horizontally as shown in Figure 4 B. However, the vertical installation is the most preferred method. When selecting a mounting location, leave enough space to allow the removal of the lamp unit (typically leave a space equal to the size of the chamber itself).
3. Mount the system to the wall using the supplied bracket. Various connection methods can be used to connect the water source to the system, however union type connectors are recommended. For validated systems, the use of a flow restrictor device will help to maintain the manufacturers rated flow. The flow restrictor should be installed on the outlet port and is designed to be installed in one direction only. Ensure that the flow of the water matches the flow direction as indicated on the flow restrictor. Refer to Figure 5.
   Note: DO NOT solder connections while attached to the system as this could damage the O-ring seals.![VIQUA Arros 9 Process Water Purification Unit

• Flow Restrictor](https://manuals.plus/wp-content/uploads/2024/02/VIQUA- Arros-9-Process-Water-Purification-Unit-Flow-Restrictor.png)

  4. Reversing the inlet and outlet ports.
     The factory configuration of the UV system is with the inlet port on the left side of the unit. If required due to plumbing installations then this can be reversed as follows:
     1. Remove the locknut found on the back side of the UV system.2. Remove the two Philips screws that attach the controller unit to the chamber.
     3. Pull the controller off of the chamber and rotate it 180 degrees. 4. Align the mounting holes on the controller with the welded

     10 stud mounts on the chamber and insert the ground wire back onto the

     threaded stud.
     5. Push the controller firmly down onto the chamber.6. Reassemble the mounting screws to secure the controller to the chamber
     7. Tighten down the locking nut to secure the grounding wire.

  5. Install the UV lamp unit into the chamber as shown in Figure 6. Twist lamp unit until fully seated then swing lamp connector around and position over top of the lamp and press down until the lamp pins are fully inserted into the lamp connector.

  6. When all plumbing connections are complete, slowly turn on the water supply and check for leaks. The most likely cause of leaks is from an O-ring seal. In case of a leak, shut water off, drain chamber, remove the lamp unit or drain plug, wipe the O-rings and threads. Clean and re-install.Once it is determined that there are no leaks, plug the system into the ground fault interrupter and check controller to ensure the system is operating properly. The controller should illuminate without any alarms.

  7. Allow the water to run for a few minutes to clear any air or dust that may be in the chamber.
     Note: When there is no flow, the water in the chamber will become warm. To remedy this, run a cold water tap anywhere in the house for a minute to flush out the warm water.

  8. Once it is determined that there are no leaks, plug the system into the ground fault interrupter and check controller to ensure the system is operating properly. The controller should illuminate without any alarms.
     Note: DO NOT look directly at the glowing UV lamp unit.

3.2 Cleaning Procedure
As UV does not provide a disinfection residual, it is imperative that the entire distribution system located after the UV be chemically disinfected to ensure that the plumbing system is free from any bacteriological contaminants. The disinfection process must be performed immediately after the UV unit is installed and repeated thereafter whenever the UV is shut down for service without power, or inoperative for any reason. The procedure for sanitizing the plumbing system is readily accomplished as follows:

1. Ensure that the unit remains powered on for the entire cleaning process.

2. Shut off the water supply.
   • Close each faucet.

3. Press the pressure button to release the pressure from the cartridges.

4. Remove sump housing(s) using sump wrench.

5. Remove cartridge(s) and pour 2 cups of household bleach solution into the filter housing(s).
   Note: DO NOT use Hydrogen Peroxide.

6. Reinstall sump only to filter head.

7. Turn on water supply.
   • Open a tap down stream and allow water to fill the chamber until you smell bleach.

8. Turn on the cold water supply followed by hot water (if available) until you smell the bleach.
   • Close all faucets and allow bleach to settle in the water lines for 30 minutes.

9. Shut off the water supply.
   • Press the pressure button to release the pressure.

10. With all faucets closed, remove filter housing(s) using sump wrench.

11. Reinstall the cartridge(s) into filter housing(s) and connect to the unit.
    • Turn on water supply and flush all water outlets until bleach can no longer be smelled (at least 5 minutes).

12. Press the pressure button to purge air and to complete the cleaning procedure.

Note:

1. The addition of chlorine (bleach) to a hot water tank that has in the past been fed with untreated raw water with high levels of other contaminants (iron, manganese, hydrogen sulphide, organics, etc.) will result in oxidation of these contaminants and may require repeated flushing of the hot water tank. This contingency must be dealt with independently under the start-up procedure for any other conditioners that may form a part of the pre-treatment for the UV unit.
2. The above cleaning procedure will result in a massive chlorine residual far in excess of the 0.5 to 1.0 mg/L typically present in municipally chlorinated water and of a magnitude consistent with the minimum 50 mg/L chlorine solution recommended for the cleaning of distribution systems known to be contaminated. Do not consume water until complete system has been flushed.
