Overview
The SCA 1200ht Support Cleaning Apparatus (SCA) is designed to remove soluble
support from FDM parts (PLA, ABS, PC, nylon) and Material Jetting (MJ) parts (UV Cured
Resins) using water or approved caustic cleaning solutions.
How it works
The SCA removes support material by immersing parts created with soluble support
material in a bath consisting of water or cleaning solution. The SCA is designed to
accommodate a broad range of material specific cleaning solutions and bath
temperatures. The gentle bath agitation dissolves the support material without harming
the underlying model material. The time required to remove the support material
depends on model geometry and the total amount of support material. When the
soluble support material is completely removed, models are unloaded from the SCA,
rinsed, dried, and ready for further finishing or use.
Package contents
The SCA is shipped with the following contents:

Note: Cleaning solutions are purchased separately and available from your printer
reseller or visit www.oryxadditive.com/support for additional information.
Major components
The SCA consists of several key components that all users should be familiar with.
Understanding the function of each component is important for the safe operation of
the system and will aid in extending the life of your SCA.
Many aspects of the SCA have been designed specifically for safety. All electrical
components are properly grounded and labeled for safety protection.

7
The Tank Area is used to hold the liquid and it is where the parts are cleaned. The SCA
improves part cleaning by circulating the liquid in the tank.
The Large Parts Basket is used to hold parts during cleaning and to lift parts out of the
tank. Users should wear thermal gloves when lifting the basket from the tank.
The Small Parts Basket is used to hold small parts during cleaning.
Figure 1 Tank Area
Figure 2 Large Parts Basket
Figure 3 Small Parts Basket

8
The Strainer over the drain opening in the tank prevents debris from entering the drain
when the tank is emptied. It should be rinsed after emptying the tank before refilling
with fresh liquid.
The Heater is located behind the perforated Heater Shield. It heats the water in the
tank.
The Spray Nozzle directs the flow of liquid into the tank. The spray nozzle can be
removed for cleaning if the holes are clogged. Simply unscrew the nozzle and rinse with
tap water to un-clog holes.
The Pump Intake Screen prevents large particulates from entering the pump. It may
occasionally need to be cleaned with a soft brush or toothbrush to remove debris
trapped in the holes.
The Temperature and Level sensors are used to sense the temperature and height of
the liquid in the tank. They are mounted behind the rear support bracket.
The Main Power Switch is located on the right-hand side of the unit. This turns power to
the unit on and off.

The Power Cord (not shown in figure) is used to connect the system to a wall outlet for
power. Only use a power cord provided by the manufacturer.
The Power Cord Receptacle is where the power cord is connected to the unit. The plug
is a disconnecting device and should be easily accessible at all times.
The Drain Tube and Drain Valve are on the front of the tank for easy accessibility.
The tank is drained by connecting a hose to the Drain Tube and turning the Drain Valve
to the open position. The liquid in the tank should be at room temperature and the unit
should be turned off and unplugged from the wall before it is drained.

Setup
Locating the SCA
To maximize ease of use and operational safety, make sure the following preparations
of the physical site are met:
•Place the SCA on a sturdy horizontal surface or cart capable of supporting 200 lbs
(the weight when filled with water).
•The selected location should be isolated from unintentional contact from those
working in the area.
•The electrical outlet must be located within 2 m (6 ft) of the SCA. Do not use an
extension cord or power strip with the system.
•The SCA should be near a grounded wall outlet such that the power cord does not
pose a hazard to people or equipment passing by.
•The grounded electrical outlet (US: 110VAC, 20A, 60Hz, single phase, Europe:
220VAC, 16A, 50Hz)
•The power cord plug-in receptacle is a disconnecting device that should be easily
accessible at all times. Position the unit so that the plug can be easily reached.
•It is strongly recommended that the unit be placed on a circuit with its own GFCI
breaker.
•Place the unit in a well-ventilated area.
•The operating environmental temperature must be between 5⁰C - 40⁰C (41⁰F –
104⁰F); and operating environmental humidity between 0% - 80% RH.
Preparations for draining and disposal
•Consult your local regulations regarding disposal of the cleaning solution effluent
prior to use. A permit or form of pre-treatment may be required.
•The SCA relies on gravity to drain the cleaning tank. Locating the system near a drain
or sink will make draining the unit much easier. Alternatively, the SCA can be kept on
a cart for easy transport to a sink or drain.
•Use a 1” inner diameter hose made of PVC or equivalent on the drain tube to
facilitate draining. Ensure the tubing or hose can withstand the temperature and
caustic properties of the cleaning solution.

Operation
Filling and setup
Adding water
Fill the tank with water to just below the MAX line as shown (approximately 11 gallons,
42L), taking into account that the parts and basket will raise the water level when
lowered into the tank.
Figure 6 Liquid Fill Lines
DO NOT use hot water when filling the tank. The addition of cleaning solution 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 MIN line as shown.
N'UTILISEZ PAS d'eau chaude lors du remplissage du réservoir. L'ajout de concentrés de
nettoyage à l'eau est une réaction de dégagement de chaleur et s'il est ajouté à l'eau
chaude, il en résultera des éclaboussures dangereuses.
Ne jamais faire fonctionner le réservoir à moins que le niveau de liquide ne soit au-
dessus de la ligne MIN, tel qu’illustré.
Adding cleaning solution
Add cleaning solution to the water filled bath in accordance with the manufacturer’s
recommendations. A list of Oryx approved cleaning solutions and proper mixing ratios
are available on the Oryx website: www.oryxadditive.com/support.

12
The following are examples of recommended mixing procedures for WaterWorks and
EcoWorks in the SCA 1200ht.
If using WaterWorks Soluble Concentrate:
While wearing protective gloves, protective clothing, and eye/face shielding, add one
bottle (2.1 lbs, 950 g) of WaterWorks to the water filled bath. Exercise caution when
working with the cleaning solution. WaterWorks contains sodium hydroxide and always
refer to the Manufacrer’s SDS for PPE and handling requirements.
If using EcoWorks:
1. Open the foil cleaning agent packet as shown. Each packet contains an A & B pouch.
2. Empty all the contents of 6 (6) foil cleaning agent packets into the water filled tank.
Avoid handling the contents of the cleaning agent bag.

13
Connect the power cord to the SCA and then to a suitable grounded receptacle.
Power on the SCA using the main power ON/OFF switch located at the rear of the unit.
Press one of the four temperature preset buttons or the Heat Off button to select the
cleaning temperature. The temperature can be changed at any time during the cycle by
selecting a different temperature button. The SCA heats at a rate of about 3 minutes per
degree.
Press the SET button and then press the up and down arrows to set the minutes. Press
the SET button again and use the up and down arrows to set the hours. Press the SET
button again to accept the time. Press the button to start the heater and pump.
Loading parts and testing level sensors
Wait until the SCA has reached the desired temperature before loading parts into the
tank. This minimizes the time the parts are immersed in the cleaning solution.
To load parts for cleaning, place parts inside the large cleaning basket. If cleaning small
parts, place the parts inside the small basket and set the small basket inside the large
basket. Close the basket lids.
Before placing the basket into the cleaning solution, press the button to pause the
heater and pump. With the basket cutout facing the nozzle, slowly lower the large parts
basket into the solution-filled tank. The flow nozzle should be centered on the basket
cutout.
If the high level alert lights and the alarm sounds, press the button to silence the
alarm, and remove liquid until the alert indicator is no longer lit.
Note: It is recommended that the level sensors be tested periodically. Adding water to
just above the MAX fill line should cause the high level alert to illuminate and the buzzer
to sound. Draining water until the liquid level is below the MIN fill line should cause the
low level alert to illuminate and the buzzer to sound. If the level sensors are properly
working the system will not operate until the liquid level is between the MIN and MAX
fill lines.
Close the lids on the SCA to prevent heat loss and evaporation. Never place your face
near the tank when opening the lid –vapors from the cleaning solution may cause eye
and respiratory irritation.
Fermez les couvercles de SCA afin d’éviter la perte de chaleur et l’évaporation. Ne
jamais placer votre visage près du réservoir lorsque vous ouvrez le couvercle ; les
vapeurs s’émanant de la solution de nettoyage pourraient causer de l’irritation des yeux
et des voies respiratoires.

14
Cleaning the parts
To activate the cleaning cycle after setting the time and temperature, and adjusting the
liquid level, press the button. Illuminated bars will sweep under the temperature
display when the pump is operating.
Parts can take a few hours or longer to clean. Cleaning time is affected by the size of the
part, the amount of support material, part geometry, and the pH level of the cleaning
solution.
Parts can be checked at any time during a cleaning cycle by opening the lid, carefully
lifting the Large Parts Basket from the tank, turning the basket 90° and resting it on the
rear support bracket and then pulling it forward on to the front tank ledge.
Protective gloves and eyewear should always be worn when lifting the basket from the
tank.
If the parts are clean before the end of the cleaning cycle, halt the cycle by pressing the
button.
Des gants de protection et des lunettes protectrices devraient être portés en tout temps
lorsque vous soulevez le panier du réservoir.
Si les pièces sont propres avant la fin du cycle de nettoyage, cessez le cycle en appuyant
sur le bouton .

Completing the cleaning process
Removing parts from the SCA
When the parts are clean, they can be removed from the SCA. Halt the cleaning cycle by
pressing the button if removing the parts before the timer has finished count down.
Open the SCA lids and slowly lift the large basket from the cleaning solution. Rest the
basket over the tank by setting the basket lugs (pins) on the support brackets and inner
rim of the tank.
Protective gloves and eyewear should always be worn when lifting the basket from the
tank or handling wet parts prior to rinsing.
Des gants de protection et des lunettes protectrices devraient être portés en tout temps
lorsque vous soulevez le panier du réservoir ou lorsque vous manipulez des pièces
mouillées avant qu’elles n’aient été rincées.
Let the basket rest above the tank while draining. After draining, remove the parts from
the basket and rinse them with water to remove any residual cleaning solution. Air dry
or pat dry with a soft cloth or paper towels.
Readiness for the next cleaning cycle
After removing recently cleaned parts, lower the large basket into the tank and close
the lids. If the SCA is used periodically, use the 50⁰C temperature preset to maintain the
water at an elevated temperature. This will shorten the time required to heat the water
to an optimal cleaning temperature of 70⁰C or 85⁰C while still conserving energy.
Alternatively, the SCA can be turned off by pressing the ON/OFF rocker switch at the
back of the unit.
If the SCA will not be used for an extended period of time, all liquid should be drained
from the tank and the power cord removed from the wall receptacle.

16
Maintenance
Draining the tank
For safety reasons, allow the cleaning solution to cool to room temperature before
draining and wear protective gloves and eyewear while working with the effluent.
Pour des raisons de sécurité, laissez la solution de nettoyage refroidir jusqu’à la
température ambiante avant le drainage, et portez des gants et lunettes de protection
lorsque vous travaillez avec les effluents.
Power off the unit and unplug from the wall receptacle.
Ensure the drain strainer is in place at the bottom of the tank.
Attach a 1 inch (25.4 mm) inner diameter hose or tubing to the end of the drain tube.
PVC tubing or equivalent will withstand the caustic properties of the cleaning solution.
Place the other end of the hose in a drain or suitable container for transporting the
effluent. Open the drain valve. After draining, make sure the valve is closed.
Figure 8 Drain Valve Position
Disposing of solution
Consult your local regulations regarding disposal of the cleaning solution effluent.

17
Proper disposal requires the alkalinity (pH) of the used solution be reduced to allowable
levels before disposal. The pH may be lowered by either diluting the solution or by
neutralizing it with an acid such as malic acid.
If using WaterWorks, dilute the solution at a ratio of 5 parts clean water to 1 part used
solution. More dilution may be required, please check your local regulations.
If using EcoWorks, a dilution of 1 part clean water to 1 part used solution is usually
sufficient. More dilution may be required, please check your local regulations.
Cleaning the SCA
Apply mild soap and water with a sponge or cloth to clean the exterior surfaces of the
SCA and the inside of the tank. Never immerse the system. Any liquid in the electronics
area of the system may cause damage or system failure and void the warranty.
Contact the manufacturer for advice on cleaning the inside of the tank if stronger
cleaning agents are required.
Inspecting and cleaning the drain strainer
The strainer should be cleaned every time the tank is refilled to keep it free of debris.
Never remove the strainer if the tank is filled with used cleaning solution. Doing so
allows debris to clog the drain tube.
Remove the strainer by using the strainer handle to lift it up and out of the tank drain.
Scrub debris from the strainer using a nylon brush or toothbrush. Rinse with water.
Verify all holes are unplugged before replacing the strainer in the drain.
Figure 9 Removing the Drain Strainer

18
Inspecting and cleaning the pump intake screen
The pump intake screen may become clogged with debris. This will noticeably reduce
the flow in the tank.
Remove the intake screen by pulling down with sufficient force to unseat the fastening
clips from the mating surface. Scrub debris from the intake screen using a stiff brush.
Rinse with water. Verify all holes are unplugged before replacing the screen on the
pump intake.
Moving the SCA
Always use two people to lift the SCA. The SCA should always be drained before moving.
To lift, have each person stand on either side of the unit and place their hands into the
indentations under the unit. Lift the unit to a cart or wheeled table for transport.
