13 UV Precaution and UHM Lamp Precautions

Be sure to unplug the power cord from the power outlet when replacing the lamp. Because the lamp reaches a very high temperature during its operation, wait until it cools completely when replacing the Lamp Unit. The lamp emits small amounts of UV-radiation, avoid direct-eye contact with the light. The lamp unit has high internal pressure. If improperly handled, explosion might result. Because the high pressure lamp involves a risk of failure, never touch the lamp wire lead during the service....
