1. The working voltage: 220VAC / 50HZ (can buy a stable transformer);
2. The working temperature: 10 ℃ ~ 40 ℃;
3. Relative humidity: 30% to 80%;
4. Do not work in the uv flatbed printer placed above the items.
5. Please ensure that the water cooler inlet and outlet air flow flow.
6. Water cooling machine must use distilled water, must not use tap water, because there are many impurities in the water, with a long time after the transfer of dirt, thereby reducing the cooling effect of water cooling system, light intensity and life will decline.
