Leveling & Filling Process

Leveling The Sterilizer
  1. The sterilizer must be placed on a level surface.

    Note: When positioning the sterilizer on the surface, be sure to keep the back and right side of the sterilizer approximately 1" (25mm) away from the wall to allow for proper ventilation

  2. To check if the sterilizer is level: Refer to Table A; measure only the amount of water indicated in the chart for the corresponding model into a measuring cup; and, pour the measured water into the chamber.
TABLE A
AMOUNT OF WATER NEEDED TO CHECK IF STERILIZER IS LEVEL
Model Amount of Water
1730 Series & Valueklave 1730 MKV 10 - 12 oz. (300 - 355 ML)
2340 & 2540 Series 12 - 15 oz. (355 - 444 ML)
3870 Series 24 - 27 oz. (710 - 798 ML)


The water must reach the indication groove near the front of the chamber. Refer to Figure 1.If the water does not reach or it goes past the groove, the sterilizer is not level and must be adjusted.

To help level the sterilizer, the front legs of the sterilizer may be adjusted using a wrench.

Filling The Reservoir

Figure 1

  1. Use Distilled Water Only To Fill The Reservoir

    Fill the reservoir until the water level is 1" (25mm) below the base of the Safety Valve Holder. Refer to the Min/Max lines on the Reservoir Dip Stick.

    Caution! For proper operation of the sterilizer, do not fill water above the Safety Valve Holder
 

Planned Maintenance

Caution! Before Starting Any Maintenance Or Repairs: (1) Turn The Sterilizer Off (2) Unplug The Power Cord From The Wall Outlet (3) Verify There Is No Pressure In The Unit (4) Wear Appropriate Protective Hand & Eye Gear
Time Period Required Maintenance Procedure
Daily Clean the Door Gasket with a soft cloth or sponge using a soft liquid detergent and water. Rinse well and leave no residue
Weekly
  1. Remove the Trays and Tray Holder from the unit. Clean the Chamber, Tray Holder and Trays with a cloth or sponge using an OEM recommended cleaner. Caution: Do not use steel wool, a steel brush or chlorinated cleansers on these parts


  2. Thoroughly rinse Chamber, Tray Holder, and Trays with clean water. Flush the Chamber. Flush the Fill hole located at the back of the Chamber by turning the Fill Knob to the FILL position for a couple of seconds


  3. Dry the Chamber, Tray Holder and Trays, and reinstall

    • Place a couple of drops of oil on the two door pins and the door tightening bolts


    • Clean the outside of the unit with a soft cloth or sponge using a non-abrasive cleaner


    • Drain and flush the Water Reservoir while using a baby bottle brush to clear any build up of debris. Refill the reservoir (see FILLING THE RESERVOIR, above)


    • When the sterilizer is cold and not pressurized, verify the integrity of the Spring and Plunger Assembly by pulling and releasing the end ring on the Safety Valve – it should spring back
      • .

    • Remove and clean Chamber Filters


    • Check and clean the Air Jet Valve by moving the wire back and forth several times to prevent debris buildup
MONTHLY Caution: During this procedure, be prepared for a rush of steam to be released with a loud hissing sound. Wear appropriate protective hand and eye gear.

During a sterilization cycle, use an insulated tool or pair of needle nose pliers to pull on the end ring of the Safety Valve, and let the steam exhaust for a couple of seconds. This will remove debris in the lines and clean the valve's orifices. Verify its closing ability.
ANNUALLY Recommended parts to be replaced at this time include the Door Gasket, Chamber Filters, Door Bellows, and parts showing wear
