Environmental temperature
The site environment and the temperature of the ultraviolet radiation intensity has a certain impact, the temperature is too high or too low will reduce the intensity of radiation, so the site environment must be kept dry and ventilated, the general room temperature of 20 ~ 40 ℃ for the appropriate temperature of ultraviolet disinfection.
Site power supply
Site power supply must use a separate line, not with the frequency pump *** with the use of a line, the voltage must remain stable. (Voltage 220±22V Frequency 50Hz±2.5
Hz) Unstable voltage will cause the lamp to flicker and burn out.
Installation location
Ultraviolet sterilizer installation should be installed horizontally (vertical installation is strictly prohibited), on-site installation of the equipment must be installed between the pump and the tank, installed at the back end of the pump due to the pump startup impact will be too large to damage the casing caused by leakage of the equipment, and can not be directly installed in the main line of the equipment, regardless of whether the choice of one or more ultraviolet sterilizers are connected in parallel, they should be Installation of bypass piping and shut-off valves to facilitate maintenance.
Installation of the foundation
Equipment should be installed on the ground above the building foundation, the general foundation must be 30-50cm above the ground (large-scale sterilizer), no foundation UV disinfection equipment should be set up bracket (small ultraviolet sterilizer), a reasonable choice of installation location, pay attention to the electrical cabinet part of the waterproofing, moisture-proof.
Space considerations
From the single end of the ultraviolet sterilizer should be left with the same length of the equipment in order to facilitate the replacement of lamps. UV sterilizer control panel should be left in front of the 0.6 meters of unobstructed space to facilitate maintenance. Electrical control box is installed near the device, the relative humidity of the environment is not greater than 80 ℃, no corrosive gases, no conductive dust, no strong vibration and shock.
