The 2-Stage Pre-Sediment Filter Kit is necessary if you want to add a drain to the Envirolet® MS10 (120VAC) and Envirolet® Waterless Remote System (120VAC), which do not include a drain kit standard.
The Envirolet® MS 10 (120VAC) and Envirolet® Waterless Remote System (120VAC) do not normally have a drain connected. A drain is recommended when there is going to be high use and/or if the system is going to be operated occasionally without using the Heater.
• You can optionally remove the Tray if not required.
• Choose the "Plastic Union" if you need the fitting that attaches to the system body and allows the drain tube to exit the system. Requires special adhesive (e.g., "Marine Goop") to properly attach and seal.
