Design Parameters

The Malmet Sanitizer has been designed within the following parameters:
a) A single bedpan with lid and two urine bottles can be emptied, cleaned and sanitized during

each automatic cycle.
The utensils that can be cleaned in the machine are:­i) Standard size bed pans

ii) Standard commode bowl
iii) Standard male and female urine bottles
iv) Most plastic urine bottles including male non-spill and female cervix
v) Small Slipper pan

b) The cradle is designed to ensure that utensils are not dislodged during the cleaning cycle,

the contents are emptied during door closure.

c) The chamber and door are self-cleaning and do not permit water or soil to remain after a

properly completed cycle. Steam sanitation ensures all internal surfaces are totally clean
and safe.

d) The flush and clean stage:

i) Removes the soil
ii) Clears the trap

e) A complete cycle is completed in approximately four (4) minutes for the 20 Amp Sanitizer

and six (6) minutes and thirty (30) seconds for the 10 Amp Sanitiser.
NOTE: Dependant on ambient air temperature.

Note: If the machine is turned off or on initial start up, the first cycle will take longer as the

machine has to raise the temperature of cold water to 90°C.

Two fixed 60° top sprays
Two fixed urinal sprays
17 litres of water is used during a 17 second wash.

Stage 2 – Cleaning / Sanitizing

Steam is delivered into the sealed wash chamber.
Steam continues to clean the utensils and increases the surface temperature of utensils

to a minimum of 90°C for 65 seconds

Sequence of Operation

1. Providing machine is installed into position with power and water connected push power on
button.

2. When the unit is turned on via the display panel the display shows fill indicating steam
generator and cold water tanks are filling to the high water level.

At this stage the unit will not commence a cycle until Step 5.

3. Once the steam tank water level probes sense the tank is full it will start heating.

4. The steam tank is heated to temperature 90°C - 9 2°C. The machine is now ready to
commence a cycle.

The display shows rdy (ready).

5. The operator breaks the infra-red beam, which opens the door.

The display shows open.
Note: Whenever the door is opened the elements are in the off mode.

6. Once the machine is “loaded” the operator breaks the infra-red beam to close the door.

The display shows shut.

7. When the door is fully closed 2 Green LED’s will flash in the infra-red sensor area for 8
seconds to advise the user to break the beam again to start a cycle.

The display shows rdy.
If the 8 seconds has elapsed the flashing LED will stop and the unit will not start for a cycle.

The operator has to repeat the process from Step 5 (or press manual start).

Note: If this occurs the beam must be broken twice.
Note: On 10A models if the steam generator temperature is not at 90°C and the beam

has been broken or the manual start button pressed. The display will show “CYCL”,
the green led’s will stop flashing and stay on. When the steam generator has reached
operating temperature the display will show Rins the wash cycle will start
automatically.

8. Once a cycle has been initiated the elements are turned on in the steam tank to start
heating the water.

The wash pump is turned on for 17 seconds for the initial wash.

The display shows rins.

9. Once the wash cycle is complete the display will flash 90 (indicating 90°C). This is the
critical temperature that must be reached before the sanitation cycle can commence. At
this point the fill solenoid is disabled and will not operate unit Step 12.

10. The elements in the steam generator heat to produce steam, which is directed into the
wash chamber raising the internal cabinet temperature above 90°C.

11. Once the internal cabinet temperature has reached 90°C the sanitization cycle will
commence. This display shows the actual cabinet temperature.

12. All 3 elements on 20 amp models and on all 2 elements on 10 amp models will continue to
heat during the sanitization cycle until the internal cabinet temperature reaches 91°C.

13. At 91°C one element will turn off and at 92°C a nother element will turn off on 20 amp
models, on 10 amp models at 91°C one element will t urn off. One element will remain on
until 15 seconds before the end of the cycle. If the internal cabinet temperature falls below
92°C the second element is turned back on the third respectively if the cabinet temperature
falls below 91°C.

Note: Regardless of element combinations 15 seconds before the end of the cycle ALL

elements will turn off. This is to overcome the effects of overshoot in the steam
generator producing steam at the end of the sanitization cycle.

14. The maximum time allowable for the sanitization cycle is 10 minutes. If this time is
exceeded then the machine will go to fault and elements turn off.
