Quick Troubleshoot
If the GUS system is not running, check the following:
1. Ensure that the unit is plugged into a live wall outlet.
2. Make sure the green On/Off switch is on. The switch will be illuminated when on.
3. Push the white ‘test’ button on the GFCI, located next to the On/Off switch. Then push the white ‘reset’
button. This should restart the system and the green On/Off switch should now be illuminated.
4. In the event that the system is still not working, you will need to check the fuse, which is externally mounted.
5. Unscrew fuse holder from the unit. The fuse holder is located to the right of the faceplate next to the fuse
label. If damaged, replace with a standard 3-amp fuse.
6. If the unit is still not working, call CIVCO Medical Solutions at 1-800-445-6741.
If you can still smell fumes from your high-level disinfectant while using the GUS system, check the following:
1. Both the soak and rinse trays are inside the disinfection soak station. It is very important that there is always a
rinse tray containing clean water for the initial rinse. Failure to do so will result in exposure to vapor when
transferring the instrument to the sink for rinsing.
2. The system is left on at all times while disinfectant is in the soak tray.
3. Lids are placed on the soak tray when not in use and during the soaking cycle.
4. Fresh disinfectant is being activated and poured into your soak tray while INSIDE the system, with it running
on high speed.
5. Disinfectant is being neutralized INSIDE the system prior to disposal.
6. Filters have been changed as recommended (every six months with daily use).
7. Spills outside of the system are immediately neutralized and cleaned up.
8. No other disinfectants are being used in the room, including inside an Automated Reprocessing System.
9. All personnel using the system have been fully trained on its use.
10. Verify that the system switches to the high-speed setting when you open the front acrylic door. You should
hear a marked increase in the noise level.
If the disposal pump is not working, check the following:
1. Check to make sure that the in-line filter on the suction hose is not clogged. If it is, you must replace the
filter. Contact CIVCO Medical Solutions for replacement in-line filters.
2. If the disposal pump is still not working, call CIVCO Medical Solutions at 1-800-445-6741.

Filling the High-Level Disinfection Tray
CAUTION: Make sure to turn the system ON before pouring high-level disinfectant into the soak tray.
CAUTION: Always leave the system running when high-level disinfectant is in the soak tray.
CAUTION: Keep the soak tray covered as often as possible, to minimize evaporation of the disinfectant.
CAUTION: Change the rinse water at least once per day.
1. Switch system ON using the GREEN lighted power switch located on the inside front of the system.
2. Open the front acrylic door. This automatically increases the fan speed, drawing more air through the
system.
3. One tray is for high-level disinfectant and the other is for clean rinse water. The rinse tray must be inside the
system with the soak tray.
NOTE: Not all trays are autoclavable. Check before autoclaving.
4. Remove the lid off the high-level disinfectant tray and set aside.
5. Prior to pouring the high-level disinfectant, read carefully and follow all label instructions.
6. Activation of the high-level disinfectant (if required) should be done inside the unit with the system turned
ON. Once activated, pour the solution into the soak tray. The rinse tray is used for initial rinsing of
instruments prior to removal from the system. Fill rinse tray with clean rinse water – change rinse water at
least daily. Refer to your instrument’s instruction manual regarding use of sterile water for rinsing.
CAUTION: It is important that you keep the soak tray containing high-level disinfectant covered at all
times to prevent evaporation.

Operation
Placing Instruments into the System
1. All scopes and instruments should be pre-cleaned and dry prior to soaking in high-level disinfectant.
2. Open the front acrylic doors of the system and remove the lid on the soak tray.
3. Gently place your instruments into the tray containing high-level disinfectant.
4. Follow instrument manufacturer’s instructions for flushing lumens and channels of scopes.
5. Replace lids and close acrylic door.
Removing and Rinsing Instruments
1. When done soaking, open the front acrylic doors and remove the lid from the soak tray.
2. Gently lift instruments from the soak tray and shake off excess disinfectant.
3. Place instruments into the rinse tray inside the GUS system to remove residual chemical.
4. Remove from rinse tray and conduct final rinsing and wiping procedures as you normally do.
5. Refer to your instrument’s instruction manual for proper rinsing and storage procedures.
6. You must leave the system running at all times when the soak tray contains high-level disinfectant.
Disposal of Disinfectant
In some states and municipalities, it is illegal to dispose of used disinfectants without first deactivating them.
Deactivation also protects the user from exposure to splashes and spills. CIVCO Medical Solutions manufactures
Glute-Out®, a glycine-based neutralizer (part # 610-1045).
After the disinfectant is deactivated, it is safe to dispose of down the sink/drain with cold water running.
Thoroughly clean and rinse out the container. With the unit turned on, put the soaking container back into place
and refill it with fresh high-level disinfectant.
Built-in Disposal System
NOTE: Laboratory (L) Models do not include a disposal system.
The built-in disposal system is ideal for emptying the soak tray from inside the system, without the risk of exposure,
splashes or spills.
A disposable in-line filter is attached to the suction hose for the disposal system, which will prevent lint and small
debris from reaching the pump. If the filter becomes clogged, you will notice a decrease in water pressure.
Replacement in-line filters can be purchased in packs of five from CIVCO Medical Solutions.
1. Verify that the main power switch is ON before disposing of high-level disinfectant.
M0035_E 8 G25-S / G25-E
GUS Disinfection Soak Station™

2. We strongly recommend the use of neutralizer (Glute-Out®) when using OPA or glutaraldehyde to prevent
splashes, spills, and exposure to vapor. Add the required amount of neutralizer into the soak tray containing
high-level disinfectant and allow sufficient time for neutralization to take place.
3. Insert the clear plastic suction hose (shorter hose with in-line filter) into the quick disconnect fitting located
next to the disposal On/Off switch on the front inside of the system. Place the other end of the hose into the
soak tray.
4. Insert the discharge hose into the quick disconnect fitting located on the left side of the system. Place the
other end of the hose into the sink or hopper drain and turn on the cold water (DO NOT USE HOT WATER).
5. Switch on the pump.
6. After all the disinfectant is pumped out, add clean water to the soak bowl, rinse and pump out. Use the
suction hose to ‘vacuum’ all liquid from the bowl.
WARNING: Failure to fully rinse out disposal system after each use may damage the system and void
your warranty.
7. Switch off the pump and disconnect the suction and discharge hoses from the disinfection soak station. Store
until needed again.
WARNING: The disposal system on your GUS system is not designed to pump solids. A disposable in-line
filter on the suction hose must be in place at all times. Failure to do so may damage the pump and void
your system warranty.
