The WSUVK200N is NSF 55 Class A certified.

This certified kit is ideal for 'mission critical' locations where the health authorities require a certified UV dosage. This means that the flow rate must be limited to allow the UV lamps to provide a dosage of at least 40 mJ cm2.

Typically this system is used for:

• control of Legionella that can be lurking in hot water ring mains in Rest Homes
• treating water prioor to delivery by water tankers

The 40mm inlet / outlet connections ensure that the 113 Lpm flow rate is maintained in all conditions

This UV Chamber is fitted with 2 x 100 watt lamps, each inside its own quartz sleeve, and is powered by 2 x electronic ballasts enclosed in a waterproof IP box.

The Chamber is ready to fix to a beam or wall with its sturdy brackets.

The lamp connection end of the chamber needs to be weather protected (to keep water of the lamp pin connections)

Sensor Alarm:

The UV Sensor in the UV Chamber may detect 'low light' (below 75% UV intensity) which will activate the 'alarm' in the WSI-PS-EC365S controller (A2)

Possible causes include:

• deposits (film coating) on the Sensor Lense (in the Chamber)
• Cloudy water 
• Weak UV Lamp

Service Requirements:

• Service when the Ballast digital display is A3 (after 365 days use)
• Clean Quartz Sleeves (2 x WSI-1035-T5Q)
• Replace back up nylon rings if damaged (2 sets WSI-T5B)
• Refit Sleeve with new silicon seals (2 sets WSI-T5S)
• Refit End Caps - lubricate threads
• Fit new UV Lamps (2 x WSI-100-1000-T5L)
• Check for leaks
• Attach Lamp Lead and switch on
• If Ballast is faulty replace with WSI-PS-EC365 or WSI-PS-EC365S
