VIQUA IHS10-D4 IHS12-D4 IHS22-D4 ultraviolet (UV) water system Owner’s Manual

VIQUA IHS10-D4 IHS12-D4 IHS22-D4 ultraviolet (UV) water system

Congratulations on the purchase of your ultraviolet (UV) water system! This system uses the most advanced UV technology on the market and is designed to provide you with years of trouble free operation with minimal maintenance.
To ensure ongoing optimal operation, UV lamps need to be replaced annually with VIQUA factory-supplied replacements. VIQUA lamps are the result of extensive development resulting in a highly efficient platform with extremely stable UV output over the entire 9000 hour lifetime. Its success has led to a proliferation of non-genuine copies in the market.
The UV lamp is the heart of the UV system, and there should be no compromise when it’s time for a replacement.
Why should you insist on genuine factory supplied VIQUA replacement lamps?

• Use of widely available, non-genuine, replacement lamps has been shown to damage the control module of VIQUA UV equipment.
• An increasing number of calls to VIQUA Technical Support are connected with non-genuine lamps being used (unknowingly) as replacements.
• Damage arising from the use of non-genuine lamps poses a safety risk and is not covered by equipment warranty.
• Unless the UV equipment is equipped with a UV sensor (monitor), it is not possible to verify the UV (invisible) output of replacement lamps.
• Similar appearance to the original lamp and the presence of (visible) blue light does not mean equivalent performance.
• VIQUA replacement lamps undergo rigorous performance testing and strict quality control processes to ensure that the safety and performance certifications of the original equipment are not compromised.

So, you can see that it’s simply not worth the risk! Insist on genuine VIQUA replacement lamps.

UV

| •        During extended periods of no water flow, the water in your chamber can become very hot (Approx. 60 °C) and potentially lead to scalding. It is recommended to run your water until this hot water has been purged from your chamber. Do not allow water to contact your skin during this time. To eliminate this condition, a temperature management valve can be installed at the outlet of your UV system.

•        Do not pass water through the UV system for a minimum of 5 minutes after applying power (including after power interruptions) to avoid passing under-treated water that may, in rare instances, pose health hazards.

•        This system contains a UV Lamp. Do not operate the UV Lamp when it is removed from the chamber. Unintended use or damage of the system may result in the exposure of dangerous UV radiation. UV radiation may, even in little doses, cause harm to the eyes and skin.

•        Changes or modifications made to this system without the consent of the manufacturer could render the system unsafe for operation and may void the manufacturer’s warranty.

Water Chemistry

Water quality is extremely important for the optimum performance of your UV system. The following levels are recommended for installation:

where UVT < 75%)

• Where total hardness is less than 7 gpg, the UV unit should operate efficiently provided the quartz sleeve is cleaned periodically. If total hardness exceeds 7 gpg, the water should be softened. If your water chemistry contains levels in excess of those mentioned above, proper pre-treatment is recommended to correct these water problems prior to the installation of your UV system. These water quality parameters can be tested by your local dealer, or by most private analytical laboratories. Proper pre-treatment is essential for the UV system to operate as intended.

Maintenance

  WA R N I N G

| •        Always disconnect power before performing any work on the UV system.

•        Always shut-off water flow and release water pressure before servicing.

•        Regularly inspect your UV system to ensure that the power indicators are on and no alarms are present.

•        Replace the UV lamp annually (or biennially if seasonal home use) to ensure maximum performance.

•        Always drain the chamber when closing a seasonal home or leaving the unit in an area subject to freezing temperatures.

•        During extended periods of no water flow, the water in your chamber can become very hot (Approx. 60 °C) and potentially lead to scalding. It is recommended to run your water until this hot water has been purged from your chamber. Do not allow water to contact your skin during this time. To eliminate this condition, a temperature management valve can be installed at the outlet of your UV system.

Replacing UV Lamp

NOTICE Do not use water during replacement of UV lamp.

Lamp replacement is a quick and simple procedure requiring no special tools. The UV lamp must be replaced after 9000 hours of continuous operation (approximately one year) in order to ensure adequate performance.

Procedure:

Cleaning and Replacing Quartz Sleeve

Note: Minerals in the water slowly form a coating on the quartz sleeve. This coating must be removed because it reduces the amount of UV light reaching the water, thereby reducing performance. If the sleeve can not be cleaned, it must be replaced.
Prerequisites:

• Shut off water supply and drain all lines.
• Depressurize the unit. Place a small pail under the unit to catch any spills.
• Remove the UV lamp. Refer to Section 4.1.

Procedure:

1. Unscrew the sleeve bolt and carefully remove it from the top of the chamber.
   Note: Sleeve may be attached to sleeve bolt. Hold sleeve with other hand while removing sleeve bolt.

2. Clean the quartz sleeve with a cloth soaked in CLR, vinegar or some other mild acid and then rinse with water.
   Note: If sleeve cannot be cleaned completely or it is scratched or cracked, then replace the sleeve.

3. Place O-ring on the sleeve as shown. Insert the sleeve into the chamber as shown in step 4.

4. Ensure quartz sleeve is properly centered in the chamber.

5. Place sleeve bolt onto the quartz sleeve, carefully push down and hand tighten onto chamber. When service is complete, assemble the prerequisites in the reverse order of disassembly.

Notes:

1.  After replacing the UV lamp or sleeve perform the cleaning procedure, refer to Section 3.2.
2.  If the system is put on a temporary by-pass or if it becomes contaminated, it is necessary to complete the cleaning procedure. Refer to Section 3.2.

Replacing Cartridges

CAUTION: The sump housings will be heavy.

It is recommended to change the filter cartridges regularly, approximately 3-4 times per year depending on water quality and usage. A gradual drop in water pressure after the filtration device is an indication that the pre-filter cartridges are nearing the end of their useful life.
