This is the original instruction, please read all manual instructions carefully before operating. VEVOR reserves a clear interpretation of our user manual. The appearance of the product shall be subject to the product you received. Please forgive us that we won't inform you again if there are any technology or software updates on our product.

GENERAL INFORMATION

1. The UV water purifier is intended for indoor use only. The UV water purifier should be protected from the elements and from temperatures below freezing. The ambient temperature in the area surrounding the water purifier should be 2-40°C (36-104°F).
2. Electrical power supplied to the UV water purifier MUST match the power requirements listed on the water purifier. Use of a voltage surge protector is recommended.
3. CAUTION: The UV water purifier must be installed into an approved ground fault circuit interrupt (GFCI) receptacle. Where a 2-prong or unprotected 3-prong receptacle is encountered, it must be replaced by a properly grounded Ground Fault Circuit Interrupt (GFCI) receptacle. Installation must be in accordance with the National Electrical Code and any local codes and ordinances by a qualified electrician.
4. The UV water purifier should be located in a dry, well-lit area that provides enough room to perform routine maintenance. This includes a minimum distance of one chamber length from the chamber end to allow for cleaning and/or changing of the lamp and quartz sleeve.
5. The UV water purifier should always be located closest to the point of use. This reduces the chance of the purified water being re-contaminated by bacteria. The UV water purifier should be located after all other water devices, such as De-ionizers, Water Softeners, Carbon Filters, Pre-Filters, Reverse Osmosis, Pressure Tanks, and Pumps. This reduces the chance of the purified water being re-contaminated by bacteria in any of these units.

Due to thermal expansion concerns and potential material degradation due to UV exposure, it is recommended to use metal fittings and at least 10" of copper pipe on the outlet of your UV chamber.

GENERAL INFORMATION

- Hg EXPOSURE: The UV lamp contains mercury. If the lamp breaks, then avoid inhalation or ingestion of the debris and avoid exposure to eyes and skin. Never use a vacuum cleaner to clean up a broken lamp as this may scatter the spilled mercury. Obey local regulations and guidelines for the removal and disposal of mercury waste.

NOTICE

• The UV lamp inside the system is rated at an effective life of approximately 8000 hours. To ensure continuous protection, replace the UV lamp annually.
• The UV system is not to be used or played with by children. Persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, are also not to handle the UV system unless they have been given supervision or instruction.
• This system is intended to be permanently connected to the water lines.
• This system is not intended to be used in or above water or outdoors or used in swimming pools when persons are in the pool.
• EXTENSION CORDS: If an extension cord is necessary, use only 3-wire extension cords that have 3-prong grounding-type plugs and 3-pole cord connectors that accept the plug from this system. Use only extension cords that are intended for outdoor use. Use only extension cords having an electrical rating not less than the rating of the system. A cord rated for less amperes or watts than this system rating may overheat. Exercise caution when arranging the cord so that it will not be tripped over or pulled. DO NOT use damaged extension cords. Examine extension cord before using and replace if damaged. DO NOT abuse extension cord. Keep extension cord away from heat and sharp edges.
• Always disconnect the extension cord from the receptacle before disconnecting this system from the extension cord. Never yank cord to pull plug from outlet. Always grasp the plug and pull to disconnect.
• If the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer or its service agent.
• Read and understand the Owner's Manual before operating and performing any maintenance on this equipment.

The radiation has been carefully conceived to provide adequate UV dosage throughout the UV chamber. The dosage, as it applies to ultraviolet radiation, is a function of time and the intensity of ultraviolet radiation to which the water is exposed. The exposure time, in seconds, is the total time it takes the water to flow through the purification chamber exposing it to the UV lamp. Exposure time is related to the flow rate; the higher the flow rate, the lower the exposure time or the lower the flow rate, the higher the exposure time. The operation of the SSE&SDE Series is as follows:

• Water enters the purifier and flows into the annular space between the quartz sleeve and the chamber wall.
• The LED indicator light, located on the ballast, provides visual indication of UV lamp operation.
• Water leaving the purifier is instantly ready for use, no further contact time is required.

Limitation of Use:

The water purifier is intended for the use with visually clear water, not colored, cloudy or turbid. See "Water Quality" section. The UV Water purifier is NOT intended for the treatment of water that has an obvious contamination or intentional source, such as raw sewage; nor is the unit intended to convert wastewater to safe drinking water.

Applications: Drinking water, residential and commercial water purification, etc.

Water Quality:

Water quality plays a major role in the transmission of ultraviolet rays. It is recommended that the water does not exceed the following maximum concentration levels:

Maximum Concentration Levels
Turbidity < 1 NTU	Manganese 0.05 mg / L
Total Suspended Solids 10 mg /L	pH: 6.5 - 9.5
Color: None	Hardness :6 GPG or 102.6 PPM
Iron: 0.3 mg /L	Tannins: < 0.1 ppm (0.1 mg / L)

CAUTION: As with any water handling device, the UV water purifier should be located in an area where any possible condensation or leakage from the system, any purifier accessory and/or plumbing will not result in damage to the area surrounding the water purifier. For added protection, it is recommended that a suitable drain pan be installed under the purifier. The drain pan must be plumbed to an adequate, free flowing drain to prevent water damage in event of a leak. There are numerous leak detection/flood stop devices, available on the market today, designed to stop flow of water, reducing the chance of water damage due to leakage. For more details regarding leak prevention and/or limiting damages due to leaks please contact your local plumber.

GUIDELINES

Additional Guidelines

• Recheck the installation before plugging the UV water purifier into power.
• Do not proceed to install the equipment when the UV lamp or sleeve tube is broken; buy a new one and continue.
• The UV water purifier system is designed for continuous operation, and frequent switching will reduce ultraviolet radiation and service life.
• If this unit falls into the water, turn off the main power and then retrieve it. Do not attempt to use this system if it has been submerged.
• Do not operate this unit if it has a damaged cord or plug, if it is malfunctioning, or if it has been dropped or damaged in any manner.
• The UV system should be installed after the filter on the return line.
• Always disconnect the water supply and completely drain the water purifier if it will be subjected to temperatures below freezing for extended periods of time. Note: To save energy, turn off the power and water supply if you do not use the equipment for a long time.

MAINTENANCE & INSPECTION

MAINTENANCE:

The water purifier is designed to operate with a minimal amount of maintenance, providing the water quality does not exceed maximum concentration levels. See "Water Quality" in the "Principle of Operation" section. Ordinary maintenance consists of:

• Lamp replacement is recommended every 8,000 hours of operation, approximately 12 months of continuous service.
• Cleaning of the quartz sleeve, when conditions warrant. It is recommended that the inspection of the quartz sleeve be performed after one month of use. If the quartz sleeve is found to be coated (not clear), then the frequency of cleaning must be increased. Deposits or discoloration on the surface of the quartz sleeve are caused by excessive levels of the subject contaminant within the water that is in contact with the quartz sleeve. Most often, false deposits on the quartz sleeve are caused by an excess of calcium (hardness), iron, or manganese.

INSPECTION:

● Regularly inspect the water purifier to ensure that the UV lamp is still in operation. - An LED indicator light, located on the ballast, provides visual indication of UV lamp operation. This provides an indication of lamp operation and does not indicate the level of ultraviolet intensity or transmission through the water. - Ballasts have a built-in audio alarm which will indicate lamp failure. - To ensure proper operation of the water purifier, regular biological testing should be performed on a schedule recommended by local public health authorities, or at minimum; at installation, quarterly for the first year of service and annually, at lamp replacement, for the life of the water purifier. - Additional testing should be performed whenever modifications, change or additions are made to plumbing system, pumps, well source water etc. to ensure adequate performance under new condition. - As with any water purifier installation, routine maintenance is necessary to ensure your equipment is operating correctly. Regular inspection must also include the inspection of the ground to ensure grounding wires are secure to both the water purifier and grounding point as originally installed. Regular inspection must also include confirmation that approved ground fault circuit interrupt (GFCI) receptacle is still operational and that water purifier is plugged into this GFCI. Any components which are damaged, or broken should be replaced.
