All Things J. Racenstein and Window Cleaning

Winters coming in and purification systems are being put away. But you have to remember that they still need maintenance even when you’re not working. A few tips:

Drain your sediment, carbon, DI filters.
RO membranes are not meant to be dry so draining them is not a great idea.
This means you need to store the RO above freezing. So, most will store the entire unit above freezing.

If your only storage area is going to go below freezing, then get some heat tape from your local hardware store and wrap the unit up with it. It will turn on and off automatically and keep the unit warm.

Make several wraps around every cartridge with the heat tape to insure proper heat coverage.

Draining the cartridges serves two purposes:
1) To prevent freezing.
2) To prevent bacteria or mold growth
