3. General description

The Stuart SI500, SI600 and SI600C orbital
incubators are ideal for mixing and aerating
various biological samples under accurate
temperature controlled conditions. The rotating
platform has a digital speed setting providing a
smooth, uniform circular motion with an orbit of
16mm. The speed range is 30 to 300rpm. There
is also an adjustable digital countdown timer
that automatically stops after the set time (1
second steps to 1h, 1 minute steps to 24h or 1h
steps to 9 days). The shaking platform has a
drawer mechanism for easy access to the
incubation vessels. The temperature is controlled
by a simple "press to set" system in 0.1ºC
intervals from ambient +5ºC to 60ºC.
The model SI600C has the additional option of
connecting to a recirculating chiller unit allowing
for applications where sub-ambient temperature
conditions (ambient -15°C, minimum 5°C) are
required.
The incubators come fitted with a fully
adjustable cradle system to accommodate a wide
range of flasks and bottles. Optional accessories
include racks to accommodate 1.5ml, 15ml and
50ml tubes.

4. Preparation for use

4.1 Electrical installation

THIS INSTRUMENT MUST BE EARTHED
Before connecting the instrument please read
and understand these instructions and ensure
that the line supply corresponds to that shown
on the rating plate. The instrument is designed
for use on 230V 50Hz. The power consumption
of the unit is 300W for the SI500 and 500W for
the SI600 and SI600C. Ensure that a mains
supply lead with the correct ratings for the
product is used. The instrument is fitted with an
IEC socket at the rear of the instrument for
connection of the mains lead. The mains supply
lead is the means of disconnection for the
instrument.
Caution: Fuses are fitted in both live and
neutral lines.
2
Fuses:
230V - 3.15A anti surge fuse. For all other
voltages always replace with an equivalent fuse
type and rating as those being removed,
alternatively see rating plate for fuse type and
rating.
This unit is supplied with two mains leads fitted
with IEC plugs for connection to the instrument.
One lead has a U.K. 3 pin plug and the other has
a 2-pin "Schuko" plug for connection to the
mains. Choose the lead appropriate for your
electrical installation and discard the other.
Should neither lead be suitable, take the lead
with the U.K. plug and replace the plug with a
suitable alternative. This involves cutting off the
moulded plug, preparing the cable and
connecting to the rewireable plug in accordance
with its instructions.
IT IS IMPORTANT THAT THIS OPERATION
SHOULD ONLY BE UNDERTAKEN BY A
QUALIFIED ELECTRICIAN
NOTE: Refer to the equipment's rating plate to
ensure that the plug and fusing are suitable for
the voltage and wattage stated. The wires in the
mains cable are coloured as follows:
LIVE - BROWN
NEUTRAL - BLUE
EARTH - GREEN/YELLOW
The appropriate mains lead should be connected
to the instrument BEFORE connection to the
mains supply. Should the mains lead need
replacement a cable of 1mm
code H05VV-F connected to an IEC320 plug
should be used. N.B. the U.K. mains lead is
protected by a 10A fuse mounted in the plug
top.
IF IN DOUBT CONSULT A QUALIFIED
ELECTRICIAN
4.2 Positioning
Place the unit on a strong, sturdy, level, non-slip
surface ensuring that there is sufficient free
space on all sides without coming into contact
with anything during use. Allow at least 100mm
at the rear for easy access to the mains power
supply lead and 200mm at each side of the
instrument.
