Electrical Installation
THIS EQUIPMENT MUST BE EARTHED
Before connection please ensure that the
line supply corresponds to that stated on the
rating label.
This unit requires a supply rated at 230V,
50-60Hz, single phase. Power consumption is
100W.
There is an IEC socket at the rear of the
instrument for connection to the mains supply.
The unit is supplied with two mains leads fitted
with IEC plugs for connection to the instrument.
One has a U.K. 3 pin plug and the other has a 2
pin “Shuko” plug for connection to the mains
supply. 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. See the enclosed instruction
sheet for advice on how to carry out this
procedure.
Should the mains lead require replacement a
cable of 1mm2of harmonised code H05W-F
connected to an IEC 320 plug should be used. 1
N.B. The UK mains lead is protected by a 10A
fuse mounted in the plug top.
The mains lead should be connected to the
instrument BEFORE connection to the mains
supply.
IF IN DOUBT CONSULT A QUALIFIED
ELECTRICIAN

❖Never move or carry the unit while beakers
are in place.
❖The SW5 may be carried by the handle on the
top of the unit.
General Description
The Stuart SW5 Flocculator is designed to ensure
repeatable conditions between samples during
water and sewage flocculation tests.
The speed control has electronic feedback to
accurately maintain the rotational speed of the
stainless steel paddles. A digital display clearly
indicates the speed, which is variable between 25
and 250 rpm. Alternatively, the use of two
adjustable pre-sets allows repetition of
pre-selected speeds at the flick of a switch.
All paddles can be easily lifted out of the samples
when required. Observation and monitoring of
samples is assisted by diffused base illumination
and a black background.
Controls (see previous page)
Figure 2 shows the controls for the SW5.
Mains on/off: This is a rocker type switch which
illuminates when the unit is on.
Lamp on/off: This is a rocker type switch which
illuminates when the unit is on.

2
Pre-set selector: This three way switch allows
selection of either variable speed (VAR), or one of
the two pre-set speeds (P1 and P2).
Speed controller: This knob controls the paddle
speed in conjunction with the press to set switch.
Turning it to the right increases the speed,
turning it to the left decreases the speed.
Digital display: This screen displays the paddle
speed in rpm.
Operation (see Fig 1 & 2)
Place the unit on a firm, level surface and
connect to the mains supply. Leave sufficient
space to access the side IEC socket.
Turn the mains and lamp switch on and observe
the fluorescent lamp illuminate. Use the blue
knob to move the stirrer paddles up or down as
required.
To position a beaker, lift the paddle up to its
maximum height using the paddle lift and place
the vessel over the illuminated base. Once the
samples are in position, lower the paddles into
the beakers to the required depth.
Selecting a variable speed
Set the Pre-set Selector to the VAR (variable)
position. Hold down the 'Press-to-set' switch and
turn the Speed Controller until the desired speed
in rpm appears on the digital display.
Selecting a pre-set speed
Set the Pre-set Selector to the P1 position. To
change the fixed speed, insert the blade of a
small screwdriver and turn the screw control
clockwise or anticlockwise until the desired speed
in rpm appears on the digital display. Now every
time the Pre-set Selector is put to the P1 position,
the stirring paddles will rotate at that speed.
If a second pre-set speed is required, set the
Pre-set Selector to the P2 position and repeat the
procedure.

WARNING: Ensure the unit is disconnected
from the mains electricity supply before
attempting maintenance or servicing.
Periodically clean the instrument using a damp
cloth and mild detergent solution. Do not use
harsh or abrasive cleaning agents.
