No, the Viqua SHF-140 should not be used for water at 3 degrees Celsius. The manual states that the disinfection system should not be exposed to temperatures below freezing, and while 3°C is above freezing, the manual does not indicate that it is designed to operate at such low temperatures.

• 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.
Safety Information Section 1 Safety Information These are the original instructions. Please read this entire manual before operating this equipment. Pay attention to all danger, warning, and caution statements in this manual. Failure to do so could result in serious personal injury or damage to the equipment.
Safety Information WA R N I N G • 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.

Operation 4.3 Cleaning and Replacing UV Sensor (SHFM models only) WA R N I N G The UV sensor is very delicate instrument. Extreme care is required when handling and cleaning. The sensor window itself is constructed from quartz which is extremely fragile, be careful you do not chip or break this quartz window. Manufacturer’s warranty does not cover damage due to neglect or misuse.

The Hi-Flo Monitored series incorporate a UV sensor which detects the discrete 254 nm wavelength of the UV lamp. This information is relayed to the VIQUA controller and is the default display shown in “% UV output”. The system will display the UV output between 50 to 99 percent. When the system drops below 50%, a low UV warning is displayed as and alternately flashes (at 2 second intervals) back to the actual UV level.

Section 5.1.5 for explanation of this feature. Note: On the VIQUA systems, the audible tone provided for lamp failure is a continuous alarm, rather than the intermittent (1 second on, 1 second off) condition on the basic VIQUA systems. 5.2.5 Solenoid Output Please contact VIQUA Technical Support for assistance with solenoid valves.

VIQUA warrants the electrical (controller) and hardware components to be free from defects in material and workmanship for a period of three (3) years from the date of purchase. During this time, VIQUA will repair or replace, at its option, any defective parts covered by the warranty.
