***Fill the bath up with water (use the clear bucket under the sink, fill this with water from the sink, pour the water into the bath) until the water level reaches 1.5 horizontal basket holes from the top
*How to fill new Sodium Hydroxide bottles:
***Turn the bath on and have it heat up to 70 degrees Celsius
**
***Take a pre-filled bottle of Sodium Hydroxide (located in the thin cabinet underneath the counter the bath sits on) and sprinkle some into the heated water
***Allow the sprinkled amount to dissolve and repeat until all of the Sodium Hydroxide in the bottle has been dissolved in the bath
***Refill the Sodium Hydroxide bottle if there is only one filled bottle left
**'''How to fill new Sodium Hydroxide bottles:'''
***Wear a lab coat, nitrile gloves, and safety goggles. This is very important. The granule Sodium Hydroxide (undiluted--undissolved) is much more dangerous.
***There should be a mini funnel in the lab somewhere (it tends to move around some). Use the large Sodium Hydroxide bottle and mini funnel to refill the small bottles up to where the level in the last remaining bottle is. Always leave one bottle filled as a gauge for where to refill to. If a bottle has not been left filled, then fill the small bottle to about 1.5 inches below where the narrowing of the bottle begins.
**'''When to change the solution in the bath:'''
***This is not an exact science. Before the F370, all dissolvable support material was a translucent black. This meant that the bath would become a milky brown when it needed to be changed. Now the F370 introduces an opaque white material which causes the bath solution to continuously appear milky which creates confusion when trying to figure out when to change the solution.
***As of right now, we recommend making a best guess. When the bath starts taking a very long time to dissolve support material, it is probably time to change the bath.
***Some thoughts for changing this in the future:
****Use the Job Log's ability to track the support material dissolved in the bath and develop a number for when the bath needs to be changed. Then set the Job Log up to alert the Lab when it has reached that number.
****Attempt to obtain translucent black support material for the F370.
****Attempt to use a chemical strength measurement to determine how strong the solution in the bath is and determine a checkpoint strength for when to switch the solution.
