Filter Changing

Filters come in big (pre-filter) and small (carbon fine filter) sizes, and can be changed individually. Filters are kept in the office.

To change, remove both filters and close cabinet door. Turn on machine.

Press up and down arrows together, until green light by tick starts flashing. Then use up/down arrows to adjust air flow. It should be at the lowest setting that gives 4 green speed dots.

Put the new filters in and turn on the machine. It should adjust to the correct flow.

Historically the filters have been marked with the date they were put in. This is now being altered so that there is a paper inside each door with the dates for upper/lower filters. Write the date filters were changed on that paper.

Filters should be changed in a ratio of 1:2 or 1:3 upper to lower. Pre-filters get clogged up easily, and changed more often. Try 1:2.

To Do: 20 Jan 2017

Change upper filter on Jaws. Tape ordinary, boring, non-lined paper into door. It doesn't have to be fancy. Mark today's date for upper and a date of early December for lower.

Notes

At date of writing, Betsy's filter is going slowly and that's fine. Jaws is not clearing the air right. Suggest shortening the pipe as well as changing the filters - there is a taped section which could be removed.
