Electrical Installation

THIS EQUIPMENT MUST BE EARTHED
Before connection please ensure that the
line supply corresponds to that shown on
the rating plate.
Model Supply requirements
STR4 230V, 50Hz
The STR4 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. 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 re-wireable plug
in accordance with its instructions.
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:
BROWN - LIVE
BLUE - NEUTRAL
GREEN/YELLOW - EARTH
The instrument is fitted with an IEC socket at
the rear for connection of the mains lead. The
appropriate mains lead should be connected
BEFORE connection to the mains supply.
Should the mains lead need replacement, a
cable of 1mm2 of harmonised code H05W-F
connected to an IEC320 plug should be used.
IF IN DOUBT CONSULT A QUALIFIED
ELECTRICIAN
Safety Advice Before Use
The unit should be carried using two hands.
Never move or carry the unit while it is in
use or connected to the mains supply.

General Description

Power
50W
The STR4 is a drive unit with variable speed
control that can be set between 6 and 60rpm.
For added convenience it also has an analogue
timer that can be set from 10 to 60 minutes.
Alternatively the unit can be set for continuous
operation. The STR4 accepts one of five
accessory drums that are designed to give
different mixing actions.
Operation
Refer to Fig. 1 to identify the parts and controls.
1. Assemble the drive unit and support
column. Ensure that the unit is not
connected to the mains supply before
assembly. Push the threaded ends of the
two connecting rods through the holes in
the support column and locate them into
the corresponding two holes in the drive
unit. Screw each connecting rod firmly into
the drive unit.
2. Place the apparatus on a firm, level surface.
3. Attach the left hand fixing of the drum to
the drum fixing on the drive unit.
4. Adjust the lateral position of the support
column so that it is at the correct distance
to accommodate the length of the drum
shaft and secure in place with the thumb
screw at the back.
5. Switch the mains On/Off and motor On/Off
switches to On.
6. Turn the speed control knob until the
desired rotation is seen.
7. For continuous operation, set the timer
knob to Manual.
8. In order to mix for a given time, set the
timer knob to the required time in minutes.
When the set time is over, the unit will stop
the rotation
