1. INTRODUCTION
1.1. USE AND FUNCTION
NC 300, NC 430, NC 570, NC 710 steam sterilizers are used at operating theatres of hospitals,
laboratories, medical and dental departments of universities, at medical waste purification
facilities and for pharmaceutical, biotechnological, veterinary sciences as well as for food sector.
NC 300, NC 430, NC 570, NC 710 steam sterilizers may be utilized for sterilization of packed or
unpacked, porous or hollow loads of textile, metal, glass and rubber material that can be sterilized
using pressurized and saturated steam. The units come with built-in operating programs for the
above mentioned loads and a special program for liquid sterilization.
The jacket system situated outside the useful volume of the unit maintains a homogenous
temperature distribution within the sterilization chamber. This jacket is also used to pre-heat
system prior to sterilization thus decreasing the sterilization duration. All parts which are exposed
to steam and water are made of stainless materials.
The system is fully automated, precluding any need for user involvement.
NC 300, NC 430, NC 570, NC 710 steam sterilizers are designed and manufactured in accordance
with international directives and EN 285, EN 61010-1, EN 61010-2-040, EN 60601-1-6, EN 61326-
1, EN 62304, EN 62366-1, EN ISO 14971, EN 50419, EN ISO 15223-1 and EN 13445 standards
under the supervision of total quality management systems ISO 9001 and ISO 13485.
This device is in compliance with WEEE Regulation.
If the warnings mentioned in this manual are not considered, NUVE will not be responsible from
their results.

7- Emergency Stop Button: Stops all the control functions of the unit. Pressing this button during
a sterilization cycle will prevent immediate opening of the door. To open the door, the user
has to discharge the pressure if the chamber is under pressure or break the vacuum inside in
case the chamber is under vacuum. Then, the pressure within the gasket channel shall be
released. Please see the “Manual Control Panel” section for further explanation.
8- Sterilization Basket: The basket in which the materials to be sterilized are placed.
9- Manual Control Panel: Activated when the “Emergency Stop Button” is pressed. The Manual
Control Panel is designed to safely open the door when the Emergency Stop Button is pressed
or in case of any failure of the control unit. The Manual Control Panel shall only be used by
the authorized personnel or the Nüve Technical Service.
Steam Discharge Button: When the chamber is under pressure, a positive value is
displayed by the chamber manometer. To dissipate this pressure, the user shall press the
Steam Discharge Button until the chamber pressure drops to zero. When the manometer
reading becomes zero, the process is finalized by pressing the button once more.
Air Intake Button: When the chamber is under vacuum, a negative value is displayed by
the chamber manometer. The chamber vacuum is broken by taking air into the chamber.
To achieve this, the user shall press the Air Intake Button until the chamber pressure rises
to zero. When the manometer reading becomes zero, the process is finalized by pressing
the button once more.
Gasket Vacuum Button: Following the “Steam Discharge” or “Air Intake” operations which
are realized in accordance with the pressure status of the chamber; the “Gasket Vacuum”
step shall be commenced by pressing the “Gasket Vacuum Button” to be able to open the
door. This step shall be stopped after two minutes by pressing the button again.
Door Open Button: Following the above listed steps, the “Door Open Button” shall be
pressed to open the door. When the door is completely open, the function shall be
terminated by pressing the button once more. The “Door Open Button” shall only be used
in case the door is closed.
