Installation

Before the installation and commissioning, please review the following factors, which may affect the performance of the sterilizer.

• a) Avoid direct sunlight or close to a heated surface. The recommended ambient temperatures are 5℃ to 40℃ with a relative humidity of 10% to 80%.
• b) Leave a minimum clearance of 30cm on the top, 10cm at the sides and the back, and enough space in the front for operation.
• c) To be operated in a clean environment on a flat, level and water-resistant surface.
• d) Recommend that the unit be kept away from potential electromagnetic sources.
• e) Use properly grounded and fused power sources, the same voltage rating as indicated on the label at the back of the unit.
• f) Adjust the feet to move the bubble inside of the level indicator, which should be balanced in the right quadrant as indicated. (Refer to figure 5.f)
• g) Connect the waste barrel to the unit to collect the steam and the condensed water from the cassette. (Refer to figure 5.g)
• h) Remove the reservoir cap to pour the water into the reservoir, a maximum of 3.4 litres. (Refer to figure 5.h)
• i) Use distilled water, pure water or ultra-pure water with a conductivity of less than 10μS/cm.
• j) To empty the reservoir, remove the plug at the end of the drain tube.

Sterilization cycles

UNWRAPPED CYCLE

Used for the sterilization of solid metal instruments, such as pliers and forceps. Dental hand-pieces can be sterilized in this cycle. Total load up to 1 kg. Put the unwrapped instruments, which neither touch each other nor touch the cassette surface, on the instrument rack.

WRAPPED CYCLE

Used for the sterilization of solid and hollow metal instruments sealed in paper or plastic bags. Ensure that all wrapped instrument loads into the cassette are dry before sterilizing. Recommend to use the plastic/paper bags for wrapped instruments, the use of cloth wraps is not recommended. To allow steam penetration to all instrument surfaces, pack instruments in the bags loosely.

RUBBER AND PLASTICS CYCLE

Used for the sterilization of unwrapped instruments constructed of metal and rubber or plastics. Materials can be sterilized in this unit, such as Nylon, PTFE, polycarbonate, polypropylene, acetal, polysulfone, silicone, rubber, polyester, etc. Materials can not be sterilized in this unit, such as Polyethylene, ABS, styrene, PVC, Acrylic, latex, neoprene, etc.

AIR DRY CYCLE

This is not a sterilization cycle! It runs automatically after each sterilization cycle, the working time can be adjusted. It can not be restarted if the cassette has been removed and re-inserted. To stop the drying, just press the EXIT button at any time. If you are unsure of your instrument’s material or construction, please do not load into the cassette until you have confirmed with the instrument manufacturer.

Using a cassette

Caution, hot surface! While removing and opening the cassette after a sterilization cycle, please keep off the potential steam inside the cassette .

When not in use, don’t fully insert the cassette into the unit, leave a gap of about 2 or 3 cm. Otherwise, the unit is ready for running, the solenoid valve will be always powered ON. A sudden and forcible pushing of the cassette into the unit may damage the components inside

Setting water quality limits and pressure

Recommend to use distilled water, pure water or ultra pure water with a conductivity less than 10μS/cm. Even if the above-mentioned water stays in the reservoir for more than 2 or 3 days, its conductivity will become larger and the quality becomes worse.

How to reset?

Switch on the power, don’t insert the cassette, LCD displays “INSERT CASSETTE” as follow

• WATER QUALITY: 16.5, which means the detected quality value of the water in the reservoir. This value is a relevant conductivity value according to the manufacturer’s standard.
• WATER LIMIT: 10, which are set by the user, who is not allowed to use water below this quality. Usually
• WATER QUALITY is always lower than QUALITY LIMIT, otherwise, LCD shows an error message 3, “water quality not acceptable”. Under this circumstance, the user should change the water or enlarger the limit to continue running the unit. The water limit can be set from 0 to 50, not recommended to set it larger than 15, unless under an emergency situation.

To continue running it without changing the water inside the reservoir, you can just adjust

QUALITY LIMIT larger than WATER QUALITY.

This is only for monitoring the pressure inside the cassette, if the first value is between -5 kpa to 5 kpa, don’t need to do any adjustments. If larger than 10kpa, please contact the manufacturer.

Default sterilization cycle setting

The above values are factory settings.

• To meet different sterilization requirements, users are allowed to adjust the sterilization temperature, the sterilization time, the air drying time and the air purge times. The values can be adjusted among the minimum and the maximum.
• More air purges will allow deeper steam penetration to all instrument surfaces. Recommend to use at least 3 purges to sterilize the instruments, such as dental hand-pieces.
•  0 minutes means that the air drying cycle will not start after a sterilization cycle is complete.

Resetting a sterilization cycle

The sterilizing temperature, time, air drying and purges may vary for different instruments and loads to be sterilized. In this case, it’s necessary to reset the above values.

Take the UNWRAPPED cycle as an example:

1. Default: 135℃, 4 minutes, 5 minutes of air drying, 1 air purge
2. Reset : 134℃, 6 minutes, 3 minutes of air drying, 3 air purges

Please refer to the above steps to re-set WRAPPED, RUBBER & PLASTICS and AIR DRYING cycles in turn, if necessary

Loading Instruments

Clean and raisin all instruments before loading them into the cassette. Disinfectant residues and solid debris may affect the sterilization. Instruments unwrapped, wrapped, rubber and plastics must not be stacked or piled on the instrument rack in the cassette, not touch each other and not touch the cassette surface, as this is to ensure the steam can reach all instrument surfaces, otherwise it may lead to an incomplete sterilization. Best to allow all instruments unwrapped or wrapped to dry completely before loading into the cassette, as this is to enable effective sterilization

Running a sterilization cycle

When pull out and open the cassette, please notice the high temperature inside the cassette. It shows on the LCD as step 2.7. Caution, hot surface! While removing and opening the cassette after a sterilization cycle, please keep off the potential steam inside the cassette.

Sterilization cycle report

If the printer is set “ON” (refer to chapter 8, setting printer), there is a report as follow or a failure report with “low temperature”, “sensor errors” or “aborted”.
