The sterilizer purchased is Vertical Cylindrical Autoclave. Moist heat is
temperature of saturated steam is the most common agent because it
was noticed that no pathogenic organism has been found which could
survive at 121°C temperature. The main sterilizing agent "Steam"
comes from inside the chamber. The sterilizer chamber is made of
stainless steel.It is fitted with stainless steel door which have radial lock
and paddle lifting for easy opening and closing of door.This unit works
on.

Turn radial handle anti clockwise to remove the lid, put your leg on
lifting paddle (11) and press downwards remove the lid and turn it
towards left side. Remove the stainless basket (15) from the inside
chamber. Then ll water in the chamber up to the level of stand kept
inside the chamber. It is recommended to use distilled water for long
life of Heating element as well as low consumption of electricity.
Now, you can keep your material in the basket or drum as convenient
and close the lid.
HOW TO OPEN THE LID (2)
Connected the plug / wires to electric socked / MCB of 32 AMP. (3
Phase) for model size. MA-6 & VA-6 otherwise low (16 Amp). Of MCB
with single phase may be used to start the main supply. The red lamp
(8) will glow. Set the pressure within 15 PSI to 22 PSI in the Pizzostat by
rotating its knob (6) clock wise or anticlockwise. Now pressure control
indicator (9) will glow and shall indicate that heaters are "ON"
TO START THE STERILIZER
When the pressure is attained to 15 PS I in the pressure gauge you will
get 121°C temperature in the (1) indicator, if it is supplied which is
optional at an extra cost.
STERILIZATION
Packs should be placed in the stainless steel basket. The at packs
should be placed on the edges. Place packs in such a way to ensure
adequate steam circulation.
Do not permit crowding of packs.
Do not sterilize mixed load (such as rubber gloves with stainless steel
of heavy load s at a time)
ARRANGEMENT OF LOAD
Open the case, if supplied in wooden box packing safely remove unit
from wooden platform by removing screws from bottom.

Effective sterilization of surgical supplies is not only dependent upon
careful operation of this sterilizer but also depends upon the correct
methods of packaging and proper arrangement of loads in the steriliz-
er. Operators should bear in mind that reliable performance demand
the complete permeation of moisture and the heat-up to each and
every strand and fiber of the material and this permeation will occur
rapidly or slowly, depending upon the size and density of package.
Approximate sterilizer (exposure) period at 121°C temperature or 15
P.S.I. is as under:
1. Surgical packages in muslin wrappers 25-30mts.
2. Instruments wrapped muslin linen 30-35mts.
3. Utensils wrapped in muslin linen 15-20mts.
4. Rubber gloves in muslin 5-8mts.
5 . Interveners sets 25-30mts.
6.Treatments trays all kinds 25 -30mts.
7. Solutions (aqueous) in pyres flask 25-30mts
(These exposure periods are given just to act as guide line, however,
each user/institute should form their own standard of timing to suit
their requirement)
The vertical autoclaves are not fitted with device to creating vacuum in
the sterilizer through vacuum pump or centralize vacuum system.
Therefore,air pockets must be removed by releasing steam 3 to 4 times
before reaching the desired pressure set at 15 PSI.
