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.

3. 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.
3.1 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.
3.2 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.
