Set up ProWash S in a well-ventilated area on
a level surface in a temperature-controlled
room. Keep it away from windows and bright
light sources.
Never place anything on ProWash S.
If possible, set ProWash S near your 3D
printer and curing device for optimal
workflow efficiency.
ProWash S comes out of the box
with most parts preinstalled.
The hydrometers are precalibrated
for each chamber and will float when
it’s time to replace IPA. Read more
about hydrometers in section 4.

3Plug in and Connect to Network
4The Basics
MAX
Use the provided power adaptor and cable to plug your
ProWash S into a surge protector or uninterrupted power
supply. Flip the switch on the back to the ‘On’ position.
On startup, ProWash S will prompt you to connect to a
network. You can join an existing Wi-Fi network using the
touchscreen or use an ethernet cable. Maintaining an
internet connection will allow ProWash S to receive updates.
If you need to reset your ProWash S, switch it off and then
unplug the power cable, wait 30 seconds, then plug it back in.
Wash Chamber
This chamber is where parts are
cleaned and dried. You can wash
parts directly on the SprintRay build
platform or remove and wash them
in the basket. IPA will automatically
pump in and out of the wash
chamber from the IPA tanks.
Never pour IPA directly into
this chamber; it should only
be poured into the tanks
Failure to replace IPA when a hydrometer
floats will void your warranty
IPA Tanks
Pour IPA directly into these tanks. Each tank
has a maximum capacity of 2 liters.
Tank 1
The IPA in this tank is used for the bulk wash,
so it will need to be changed more often.
Tank 2
The IPA in this tank is used for rinsing, so it
will not need to be replaced as often. It can be
recycled into tank 1 for extended life.
Drain Ports
Each tank has a drain port designed to mate with the drain
hose attached to the back of the machine. Refer to Section 8
for instructions on how to drain.
Hydrometers
Over time, the IPA in ProWash S will become saturated
with uncured resin and lose its cleaning effectiveness.
The hydrometers are precalibrated to measure resin
saturation and will float when it is time to replace IPA.
Submerged Hydrometer = IPA Okay
When a hydrometer is submerged, the IPA in the
tank is acceptable and ready for use.
Floating Hydrometer = Replace IPA
A floating hydrometer indicates that IPA has
become saturated with resin and will no longer
effectively wash your prints. Drain the tank, clean,
and fill with clean IPA.

Build Platform Adaptor
Compatible with Pro 55 and Pro 55s
Open the tank lid and add at least 500mL of IPA 91% or greater
to each tank. IPA 99% and ethanol may also be used depending
on preference, availability, and material requirements.
If the volume of IPA is insufficient to run a cleaning cycle, the
onboard computer will detect this and notify you.
Keep the tank lid closed to prevent the evaporation and
contamination of IPA.
When new IPA is added, hydrometers may float
for a few minutes before sinking
Depending on which SprintRay 3D printer you have, you may
need to attach a magnet and/or use a fitment adaptor when
using ProWash S.
How to Install the Magnet
If using Pro95 or Pro55, you’ll need to install the provided
magnet to enable the platform wash. Thoroughly clean the side
of the build platform before attaching the magnet sticker.
Using the Build Platform Adaptor
If using a Pro55 or Pro55 S, you’ll need to use the
included adaptor to enable the platform wash. Place the
adaptor atop the wash chamber so that the opening is
on the right and run a cleaning cycle as normal.

7How to Wash with ProWash S
Print Platform Wash
Remove the basket and place the Pro95/S build platform in the
wash chamber. If using Pro55/S, use the provided adaptor (see
Section 7). Use the touchscreen to select a cleaning cycle.
The system will not start until a platform is detected.
Combination Wash
To perform a combination wash, perform a full cleaning cycle
with the build platform. Remove the models and place them in
the basket. Select ‘Extra Rinse’ from the onboard computer, or
run a second cleaning cycle from the home screen.
Basket Wash
To use the basket, place models inside and close the lid.
Use the touchscreen to select a cleaning cycle.
The system will not start if the lid is open.
Recommended for:
- Models taller than 4”
- Hollow/shell models
Recommended for:
- Highly viscous resins
- Large print batches
- Dense supports
- Complex geometries
Recommended for:
- Models shorter than 4”
- Solid models
- Models for aligners
- Surgical guides
- Night guards
Do not stack models or crowd
them together, as this can
greatly reduce wash efficiency
When washing with the build
platform, remove the basket
from the wash chamber
Drain Hose
Clipped to the back
WARNING! WARNING!
Consult your materials IFU to
determine if a combination
wash is recommended
WARNING!
Unlocked
Solvent will flow
through the hose.
Locked
Solvent will not flow
through the hose.
ProWash S comes out of the box with the drain hose clipped
to the back.
To drain a tank, press the metal inlet tip into the drain port
until it firmly clicks into place. Once connected, IPA will run
through the hose. To disconnect, firmly slide the outer ring of
the drain port away from you.
Safety Clamp
When closed, this clamp stops the flow of
IPA to prevent accidental drainage.
Metal Inlet Tip
This metal tip is designed to quickly connect to
the drain ports on the front of ProWash S.

How to Dispose of IPA
ProWash S extracts the maximum life out of IPA so that you
generate less waste. But IPA and other solvents are hazardous
and should be treated with care.
Keep the original packaging on hand for storing drained IPA
after it has become saturated. Never flush IPA down the drain.
Used IPA should be properly disposed of through a hazardous
materials collection as required by local laws and regulations.
Consult your local environmental agency or the EPA office to
find the nearest hazardous materials collection facility.
Clean Wash Chamber
Scrub the inside and walls of the chamber and remove
debris. When prompted by the onboard software, follow
the procedure in Section 11 to clean the filter.
Clean an IPA Tank
Never flush IPA down the drain. Used IPA should be
properly disposed of through a hazardous materials
collection as required by local laws and regulations.
WARNING!
For best results, clean the tanks every time
you refresh IPA. The wash chamber should be
cleaned periodically as well.
WARNING!
Retrieve the drain hose from the back of the device,
then press the metal tip into the drainage port until it
clicks into place
Point the end of the hose into a disposal container,
then unlock the safety clamp to start the flow
Once the tank is empty, eject the drain hose by sliding
the outer ring of the drain port away from you
Remove the rubber stop, then slide the
hydrometer out of the tank
Use the provided brush to scrub the inside
of the tank, including the walls
Flush the tank by pouring in a small
volume of IPA or water, then draining
Replace the hydrometer into its
corresponding tank
Clean Wash Chamber
Clean all resin and residue
buildup from the surfaces.
Clean IPA Tank
Thoroughly scrub and clean the
walls and floor of the tanks.

10 How to Clean the Wash Filter
Care for Environment
SprintRay ProWash S uses patented technology to improve the efficiency of the
washing and drying processes. It’s better for your pocketbook and better for the
environment.
Here are three easy tips to help you go the extra environmental mile with your
used isopropyl alcohol (IPA):
For additional information, visit support.sprintray.com
Never flush IPA down the drain
Keep all IPA packaging for storing used IPA
Set up IPA recycling with a materials disposal company
The secondary mesh below the removable
filter should never be removed
WARNING!
ProWash S has a mesh filter that protects the plumbing from
resin and other debris. The filter should be cleaned when
prompted by the onboard software. If the filter is damaged or
cannot be cleaned, it should be replaced.
Remove
Clear the area around the filter to ensure
no debris falls into the plumbing when it
is removed. Turn counter-clockwise by
hand to unscrew.
Clean
Flush the filter with IPA to remove
resin debris. Use the provided
tweezers to remove any additional
debris from the mesh.
Reinstall
Replace the filter and turn it
clockwise to hand tighten.
Start by Locating the Filter
In the wash chamber near the propeller
