This unique design enables easy installation of new or replacement systems as it can be positioned in multiple ways to fit tight spaces.

• This am Amalgam unit with a ballast that counts down the number of days until you need to replace the bulb. The green light on the ballast will be lit up when everything is working properly. The red light will come on and the ballast will beep when the UV is not working properly (e.g. bulb failure, leak into the quartz sleeve, short circuit).
• These UVs do not come with a manual. Before setting up we recommend you watch the YouTube Pro-MAX Setup Video.
