1. Introduction
This manual, together with the operator’s manual, forms the complete
edition of the Operation and Maintenance instructions. This manual is
intended for the use of the technician. It is forbidden for unqualified and
unauthorized personnel to service the autoclave in accordance with the
instructions in this manual. Any unauthorized service may result in the
invalidation of the manufacturer’s guarantee.
The qualified technician shall be an authorized electrician with the right
qualifications in electronics and shall be familiar with the local
technical/electrical regulations.
Available optional configurations
Models of 3870 ELVG-D model range are laboratory sterilizers
designed especially for the sterilization of instruments, liquids, and
other materials in hospital laboratories, medical laboratories, research
institutes, food laboratories and pharmaceutical facilities.
C
A special feature of the ELVCG-D models is the fast cooling stage for
liquids. In this stage pressure in the chamber is increased by means of
compressed air to compensate the fast decreasing of pressure due to
the fast cooling. The fast cooling shortens the time required for safe
handling of bottles.
Note: there is no cooling option for WR configuration
PV
Special feature of ELVCPV-D models is the vacuum pump that enables
air removal prior to sterilization and during the drying stage.
The advantages of the pre-vacuum sterilizer in comparison to the
regular gravity displacement steam sterilizer are as follows:
— Removal of air pockets from packs and porous loads and most kinds of
tubes (rubber, plastic etc.) by vacuum at the first stage of the cycle.
— Better steam penetration into the load; resulting in effective sterilization.
— Better temperature uniformity.
— Better drying of materials with closed doors due to the vacuum
achieved in the chamber at the end of the sterilization cycle.

A special feature of the autoclave is the fast cooling stage for liquids. In
this stage pressure in the chamber is increased by means of
compressed air to compensate the fast decreasing of pressure due to
the fast cooling. The fast cooling shortens the time required for safe
handling of bottles
There is a configuration equipped with fan that allows to shorten the
cooling operation.
BH
In ELVCPVBH-D (bio-hazard) models, a bio-hazard filter installed in the
chamber enables sterilizing bio-hazard load without contaminating the
surrounding.

2. Installation Instructions
The following utilities have to be connected (Refer to the drawing below
‘Rear View’ of the autoclave).
Power outlet, as detailed in the table below:
Power
3 Ph, 400V/50/60Hz
Recommended Circuit Breaker
20A
If the 3 phase autoclave has to be connected to a one phase power
network, 1 x 230V, 50/60Hz., connect the 1ph 230V power source to
the supplied switch box that has a 1 phase input (from the power
source) and a 3 phase output (to the autoclave). See details at the end
of this manual.
The power network must be protected by a current leakage relay.
Mineral-free water having a conductibility lower than 15µs
(microsiemens), through a 1/2” flexible hose.
To obtain water quality meeting requirements a deionization
column or reverse osmosis apparatus can be installed. The water must
be delivered at a pressure of 2-3bar. A pressure reducer shall be
installed at the water source outlet as instructed below.
For fast cooling (if this option is provided):
Feed water from the water network, pressure 2-3bars, connected
through a 1/2” pipe. A pressure reducer shall be installed at the water
source outlet as instructed below.
Compressed air, from a mobile compressor or compressed air network
at pressure 3-4 bars, will be set at 1.6-2bars at the autoclave inlet is to
be connected by a flexible conduit of 3/16”.
The air must be of instrumental quality filtered at 5µ and free of
humidity and oil drops.
Drain connected by 1/2” pipe, located at the rear of the unit. The
chamber exhaust and coolant water is evacuated to an open waste
funnel. The drainage piping must be heat resistant, to 80ºC, non-
continuous flow.
Attention:
Connection of water system to the autoclave must be performed
through "BACK FLOW PREVENTION SYSTEM" installation as per
EN 1717.

2.1 Installation Site
1. Install the autoclave according to the following guidelines:
2. Place the autoclave on the floor. Verify that the surface is leveled.
3. All utility supplies must be prepared in accordance with requirements,
before autoclave installation e.g. mineral-free and tap water,
compressed air, one or three-phase power network, connection to the
drain of the building.
4. Leave the space free around the autoclave for maintenance and
service requirements.
2.2 Connection of the pressure regulator
This paragraph refers to the pressure regulator of the feed water and to
the pressure regulator of the mineral free water.
1. Attach the pressure regulator to the facility's water outlet.
2. Connect the supplied flexible hose to the pressure regulator's assembly
outlet and to the autoclave's water inlet.
3. Verify that the pressure regulator is in right direction. The flow direction
is indicated by an arrow stamped on the pressure regulator.
4. Verify that water flows freely in the feed water and in the mineral free
water lines.
