Installation

NOTICE – The first step in starting your installation is to inspect the Ultra UV2 unit for damage, paying close attention to the quartz tube.

Locating the Ultra UV2 Unit

Your unit can be installed indoors or outdoors. When considering the location for your Ultra UV2 unit, keep it close to your power source. Check the silver product label for the voltage of the unit. The Ultra UV2 unit will need to be powered from either a 120V/15A/50/60Hz or 230 V/15A/50/60Hz electrical circuit (which MUST match the unit power requirement noted on the silver product label on the Ultra UV2 unit as shown below). DO NOT CONNECT TO ELECTRICAL POWER NOT SPECIFIED FOR YOUR UNIT. Plug in units must be installed on a GFCI outlet. The GFCI must be outdoor rated if installed outdoors. Hard Wired Ultra UV2 units can be wired for 120V or 230V.

  WARNING – DO NOT CUT OFF corded plug from the 120V Ultra UV2 units and hard wire it.
This does not meet the U.L. installation method and voids the U.L. listing.

1. Power Requirements (Silver Product Label)

Mounting the UV Unit on a Solid Base

Before you make the permanent plumbing connections, be sure the Ultra UV2 unit is on a solid level base with aligned plumbing connections. Make sure there is ample space above the unit for lamp replacement. After making your plumbing connections, anchor the unit to the base using the four ¼” mounting holes. FAILURE TO PROPERLY SECURE THE UNIT MAY CAUSE NOISE OR VIBRATION.

Installing Inlet/Outlet Unions

The Ultra UV2 unit comes with female socket glue-in inlets and outlet openings. ABS to PVC multipurpose glue and appropriate primer must be used to glue fittings into the Ultra UV2 body. The 4 outlets (top) and 4 inlets (bottom) provide the most versatile piping alternatives for the installer. 1 and 2 lamp units include two unions for plumbing inlet & outlet pipes. 3 lamp units include four unions for plumbing inlet and outlet pipes as shown on page 7.

NOTE: To install the union onto the Ultra UV2 unit, glue and insert the union spigot end into the inlet and outlet opening selected. Then, using the six plugs provided, glue the plugs into the remaining unused plumbing openings. Hand tightening the union nuts until snug is sufficient. DO NOT OVER TIGHTEN. Over tightening may break the molded plastic parts of the union.

NOTICE – 24 hour cure time is required before pressure can be applied to the Ultra UV2 unit.

Plumbing the Ultra UV2 Unit

All plumbing methods are illustrated with and without the bypass option. Your Ultra UV2 unit will need to be plumbed into the circulation system. The Ultra UV2 unit must be installed directly after the filter. Installing a bypass is not recommended (see page 6).

NOTICE – An improperly used bypass installation may not meet the minimum required flow rate and could potentially damage the Ultra UV2 unit.

NOTICE – Do not plumb the Ultra UV2 with a bypass unless absolutely needed. Failure to follow the instructions can result in damage to the Ultra UV2 that is not covered by the warranty.

  DANGER – Turn off the power at the main source before disconnecting or connecting the Ultra UV2.

NOTICE – Using the supplied unions is strongly recommended.

Gluing Piping to the UV Unit
Two Inlet/Outlet unions are supplied on 1 & 2 lamp units and 4 unions are supplied on 3 lamp units. Your PVC supply piping should be glued into the union tail pieces using an appropriate primer and ABS to PVC cement. Inlet piping should be supported and should not rest solely upon the unions, to avoid stressing or breaking the unions. Allow the glue to set following the glue manufacturers recommendations before pressure testing. A minimum of 24 hours is recommended. Maximum test pressure for the Ultra UV2 is 50 PSI / 3.45 BAR as noted on the silver label on the unit. If local codes require the pressure test to be higher than the max operating pressure on the silver label, use the bypass (if the unit is plumbed with a bypass) to ensure that the Ultra UV2 is at or below the max operating pressure.

A. Plumbing the Ultra UV 2 Unit with Optional Bypass Valve
Installing a bypass is not recommended and should only be considered:

1. To allow for removal of the UV unit for winterization, servicing, repairs, or replacement, while still allowing water to flow through the system. Before bypassing the Ultra UV2 for removal, turn off all pumps and allow the pool system’s pressure to drop to zero.
2. If system pressure testing above 50 psi is required (max Ultra UV2 pressure is 50 psi / 3.45 bar).

B. Installing Optional Flow Switch if the Top of the Unit is Below Water Level
The pressure switch can always be on if the Ultra UV2 unit is plumbed below water level. To prevent damage to the unit and its surroundings, an optional flow switch must be installed. If the Ultra UV2 unit is plumbed on a bypass, the optional 2 inch Flow Switch (part #004-402-0010-00 for 230V or part

004-421-3824-00 for 120V), must be on the outlet side of the Ultra UV2 unit

and plumbed after the two way valve and before the tee into the return line. Please refer to the instructions supplied with the flow switch for plumbing and wiring.

Typical Plumbing With and Without Bypass
The inlet(s) is at the bottom of the unit and the outlet(s) at the top. The maximum operating pressure for the Ultra UV2 is 50 PSI / 3.45 BAR. The minimum operating pressure is 5 PSI / .345 BAR. Please refer to the silver label on the unit for maximum operating pressure.

To reduce the risk of electric shock, this terminal must be connected to the bonding lug in the electrical supply service panel with a continuous copper wire equivalent in size to the circuit conductors supplying this equipment. To reduce the risk of electric shock, connect the local common bond grid in the area of the pool or spa to this terminal with an insulated or bare copper conductor per national and local codes. The electrical installation is now complete.

System Start-Up

NOTICE – Do not connect the pressure switch until the pool is operational!

Pressure Switch

The Ultra UV2 unit is equipped with pressure a switch that does not allow the UV lamp(s) inside the unit to light unless there is at least 2 PSI (0.137 BAR) inside the Ultra UV2 reactor chamber. This will ensure that the lamp(s) will illuminate when the Ultra UV2 unit has water flowing through the reactor.

Connecting Pressure Switch
Disconnect power to the Ultra UV2 unit. Remove the cover (Fig. 6) and locate the pressure switch and the loose lead with the female spade connector (Fig. 7). Connect the female spade connector to the male top spade connector on the pressure switch (Fig. 8). Replace the cover and restore power to the unit. Turn on the pump and when the flow switch is activated, the unit should be on and the lamps illuminated. Look at the “Glow Ring” in the center of the unit to check that all lamps are lit. If the lamps are not lit, please check the following:

1. Adjust the system valves to ensure adequate flow through the Ultra UV2 unit.
2. Increase the pump speed to produce enough pressure to energize the Ultra UV2 unit.
3. Refer to the troubleshooting section of this manual (page 17).

NOTICE – The filter gauge DOES NOT indicate the pressure in the UV unit.

WARNING – Do not look directly at the lamps.
Serious injury will occur.

Water Chemical Balance

If you have installed your Ultra UV2 unit on any water vessel other than fish ponds or ponds with live plants, it is important that you check and adjust the chemical balance of the water. The Ultra UV2 unit dramatically reduces the need for chemical sanitizers, but a minimum sanitizer residual must be maintained.

Normal Operation

Configuration for Ultra UV2 units installed with bypass. During normal operation, the inlet valve #2 and outlet valve #3 should be completely open and the bypass valve #1 should be completely closed. This instruction applies to all systems with a single speed or with a variable speed pump. This type of damage is not covered under the factory warranty. Any partial opening of the bypass valve can drop the flow rate below the required minimum and cause damage to the Ultra UV2 unit.

3. Inlet Valve #2 CLOSED

Maintenance

Winterization of Your Ultra UV2 Unit

If you are in a sub freezing climate, you must winterize the Ultra UV2 using either option #1 or #2. Failure to do so will cause damage to the unit, which is not covered under the warranty.

Option #1 – Removing the unit for the winter: Turn off the power to the unit. Disconnect the unions on the plumbing to ensure that the unit is completely drained. Now, with the power off, disconnect the unit from its power source and place the drained unit in a safe place that has a sustained temperature above freezing. Reinstall after the temperatures are considerably above freezing.

Option #2 – Leaving the unit in place for the winter: Turn off the power to the unit. Disconnect the unions on the plumbing to ensure that the unit is completely drained. There is a cup in the bottom of your unit that the quartz tube nests in. This cup (shown on the right) does not drain completely. To remove the water from this cup you must first remove the lamp array and quartz tube. Turn the unit on its side with the unions facing down until all of the water has drained. Reconnect the unit, the quartz tube, lamps, and cover. You may store the lamps and quartz tube in a safe place.

FAQs

Is the Ultra UV 2 unit designed for use in salt water applications?
Yes. Paramount’s Ultra UV2 units are fully compatible with all salt water environments. The quartz tube could require more frequent cleaning in a salt water environment.

Do I need to turn my Ultra UV 2 unit off when I backwash my filter?
No. The unit does not energize because it is not under pressure during backwashing. If you have a cartridge filter, turn off the power prior to opening the filter.

What would shorten the lamp life of the Ultra UV 2 unit?
Multiple daily cycles can shorten lamp life. Oils from touching the lamps with bare hands.

Is there any residual effect from UV?
No. All of the sanitizing is done in the reactor.

Can the Ultra UV 2 unit be mounted horizontally?
No, vertical mounting is required to maintain the weatherproof integrity of the electrical enclosure cover.

Can the Ultra UV 2 unit be installed below the vessel’s waterline?
Yes. But if the unit is below water level you must install a flow switch. See pages 6 and 7.

Can multiple units be used together for larger systems?
Yes, you can pipe any number of Ultra UV2 units in parallel. See page 7.

Must I use a GFCI (Ground Fault Circuit Interrupter) with my UV unit?
Yes. But consult your local and national electrical codes as there could be other requirements. You must use a G.F.C.I. receptacle on the 120V plug in unit. When using a 230V hard wired unit, use a 15A G.F.C.I. breaker.

Troubleshooting

Identifying and Correcting System Problems

The list below will help guide you through any problems you may have at the time of initial installation or in the future. For additional assistance, contact your supplier or Paramount technical support.

The UV Lamp(s) Will Not Illuminate
If this occurs upon initial start-up, the problem could be caused by a number of issues:

1. Not enough system back pressure to activate the pressure switch.
   a. Make sure the system filter and all debris baskets are clean.
   b. Verify that the Ultra UV2 unit is operating at a minimum of 2psi, which is required to activate the pressure switch. Please note that the filter gauge does not indicate the pressure in the UV unit.
   c. If the operating pressure of the Ultra UV2 unit is below 2psi: Restrict flow in the return manifold to create enough back pressure to activate the pressure switch. If using a variable speed or multi speed pump, be sure that the high speed setting does not create excessive system back pressure once you’ve adjusted the flow. Alternatively you may need to increase the low speed setting of the pump to achieve the minimum required pressure.

2. All Ultra UV2 units come with the pressure switch disabled. To ensure the pressure switch is properly enabled, refer to page 10.

3. Check if the pressure switch is functioning properly. With at least 2psi pressure at the vessel, see if the switch is open. The pressure switch can be checked by turning off the power to the unit while maintaining a pressure of 2psi or higher in the unit. With the power off and the unit under pressure, disconnect the 2 leads to the pressure switch and check for continuity across the 2 pressure switch terminals. If you have continuity, the pressure switch is good (closed under pressure). Relieve the pressure from the unit and check the continuity between the 2 terminals of the pressure switch. If there is no continuity without pressure in the vessel, the pressure switch is good in the open position. If the pressure switch checks good in both the open and closed positions, proceed to checking the lamps.

4. Check if the UV lamp(s) has/have become disconnected from the lamp connector(s). Disconnect the power servicing the Ultra UV2 unit, remove the cover and confirm the lamp connector(s) is/ are firmly locked together. At the same time, check all exposed wires for a possible loose connection. Reestablish power ONLY after the cover has been re-installed on the Ultra UV2 unit.

5. Verify that the electrical cord is plugged into an energized electrical outlet or properly connected to the power source. Test the electrical outlet. You should confirm the availability of the same power as indicated on the electrical label on your Ultra UV2 unit.

The UV Lamp(s) Is/Are No Longer On
If this occurs after the unit has been operating successfully for a period of time:

1. One or more lamps have failed. Replace the UV lamp(s).
2. A ballast has failed. Contact your supplier or Paramount for assistance in obtaining a new ballast.
3. Verify that the electrical outlet is supplying the proper voltage and that the cord is securely plugged into the outlet or connected to the power source.
4. Verify that the GFCI has not tripped. To verify the operating state of the GFCI, trip the GFCI manually and reset it manually. The GFCI should reset. If it does not, it indicates a fault to ground in the electrical circuit or the Ultra UV2 unit itself. Contact your supplier for assistance.
5. The ballasts have internal protection that will power down the lamps in the case of an electrical event. Power down the unit for 5 minutes. This will reset the internal protection. When the power is returned, the internal protection is reset.

The Water is Green
Green water is an indication that the UV rays generated by the Ultra UV2 unit are not effective or are not being generated by the UV lamp(s).

1. Check the lamp(s) to make sure all lamps in your system are ON (by viewing the lamp(s) through the clear viewing band on the center of the reactor. If all lamps are not ON, follow the procedures on page 17 regarding the UV lamp not lighting.
2. Run your unit longer. If your unit is operating on a time clock, run the circulation pump longer to allow the Ultra UV2 unit to function fully.
3. Clean the quartz tube(s).
4. Replace the UV lamp(s) nearing the 2½ year useful lamp life. After 2½ years of operation, the UV lamp(s) are only 80% as effective as when new. This is normal for all long life low-pressure type UV lamps, which are the longest useful life lamps available for this type of application.
5. If your Ultra UV2 unit is installed on a swimming pool, shock the pool with the sanitizing chemical you normally use and balance the pool water as per your chemical manufacturer’s specifications.
6. Your unit is not sized for the flow and duration specific to your pool.

The GFCI Has Tripped
The GFCI will protect the Ultra UV2 unit and any other equipment on the same electrical circuit from any fault to ground, the same as the electrical breaker protects the total electrical circuit from a short. When the GFCI trips, it is an indication that there is an electrical problem that must be corrected to provide a safe operating environment for your installation. Follow the instructions of the GFCI manufacturer for more information on correcting the issue if the problem is with the GFCI.

1. If you suspect that the problem is with the Ultra UV2 unit, disconnect the Ultra UV2 unit from the electrical receptacle. Reset the GFCI at the breaker panel or at the receptacle. If the GFCI does not reset, have the GFCI replaced by a licensed electrician. If the GFCI does reset, first run the circulation pump, and if no GFCI trip is encountered, plug the Ultra UV2 unit into the electrical receptacle and make sure the pump is ON. If the GFCI trips, it is an indication that there is a ground fault inside the Ultra UV2 unit. Follow the instructions previously given for opening the electrical enclosure cover and inspecting the Ultra UV2 unit. Call a qualified technician.
2. If water is present inside the electrical enclosure cover, it will trip the GFCI. Following instructions given on page 13 to remove the quartz tube(s), inspect for quartz tube cracks or breakage or for a bad quartz tube seal. Replace the quartz tube if it is cracked or broken. If not, reseal it.
3. If the Ultra UV2 unit trips when performing the test noted in Step 1 above, you can check to determine if a UV lamp is the GFCI trip cause by unplugging the individual lamp from the lamp connector, then place the electrical enclosure cover back on the Ultra UV2 unit and power up the circulation pump. If the GFCI does not reset, then the problem is either with the remaining lamp(s) or with a ballast. Remove all the lamp connectors and reset the GFCI after replacing the electrical enclosure. If the GFCI still trips, unplug all ballasts. If the GFCI resets, then plug in first one ballast, and if your unit has two ballasts, then the second ballast after the first ballast has been tested. If either ballast trips the GFCI, then replace that ballast. Refer to page 21 for the proper ballast part number. Reset the GFCI and if it does not trip, attach the electrical plug to a UV lamp (one at a time if multiple lamps are present in your Ultra UV2 unit). If it trips with the lamp lit, it indicates that a UV lamp is causing the fault to ground. Replace the UV lamp.

The Ultra UV 2 Unit Makes Noise When Operating
This is an indication of the Ultra UV2 unit not being properly attached to a firm mounting base of concrete using bolts (not supplied) placed through the mounting holes in the Ultra UV2 unit base. Attach the Ultra UV2 unit correctly to a firm base as described in page 5.

Water is Dripping from the Electrical Enclosure Cover
Water exiting the unit through the electrical enclosure cover can be attributed to either (a) a bad quartz tube seal, or (b) a broken or cracked quartz tube. Check the quartz tube seal and quartz tube as instructed on page 13.
