SCA 1200HT User Manual
8: Operating Your SCA
Although the SCA is simple to operate, it is critical that all users follow the instructions in
this manual and adhere to all safety guidelines.
8.1: Fill the Unit with Water
Make sure that the strainer is clean. Make sure
that the drain valve is in the closed position.
Fill the tank up almost to the MAX slot on the
rear support bracket. If you plan on running
large parts, it is advisable to fill to a lower level
(but above the Minimum level) to make room
for the parts and basket. DO NOT use hot water.
The addition of WaterWorks to water is a heat-
releasing reaction and if added to HOT water
will result in dangerous spattering.
Never operate the tank unless the liquid level is above the liquid level MIN slot on the heat
shield. This is just below the bottom edge of the rear support bracket.
8.2: Add Cleaning Concentrate to the Tank
Users have two approved options for cleaning concentrate: either WaterWorks or
Ecoworks, both available from your local Stratasys reseller. The WaterWorks soluble
concentrate contains Sodium Hydroxide and care must be taken when working with the
solution and when disposing of it. Refer to section on Maintaining your SCA for disposal
instructions. The Ecoworks cleaning agent is both user- and eco- friendly. The
WaterWorks concentrate will generally remove support material in less time than the
Ecoworks. However, no personal protection equipment is required when handling the
Ecoworks concentrate and only dilution is required when disposing of the used solution.
If Using WaterWorks Soluble Concentrate:
Wearing protective gloves and proper eye protection
, carefully and slowly add one
bottle (950 grams) of WaterWorks Soluble Concentrate P400SC into the filled tank. Never
add concentrate to a tank without water.
Optimal pH for the cleaning solution using
WaterWorks is 12.6, and the solution begins to lose effectiveness below 11.5pH. Using
litmus paper on a room temperature sample of the solution is sufficiently accurate to
determine the pH.
If Using Ecoworks Cleaning Agent:
Carefully remove the entire contents of six packages (foil bags) and gently drop them into
the water in the tank. Make sure to use both sides A and B. Never place the cleaning agent
in a tank without water.
Note: As the parts are cleaned the cleaning solution becomes saturated with the support
material and loses its effectiveness. Refer to the Troubleshooting section for further
information about determining when the solution requires replacement.
