1 Safety
The following symbols marked on the equipment mean:-
Caution: Read these operating instructions fully before use and pay particular attention to sections
containing this symbol
Caution: Surfaces can become hot during use.
Always observe the following safety precautions
Use only as specified by the operating instructions or the intrinsic protection may be impaired.
After transport or storage in humid conditions, dry out the unit before connecting it to the supply
voltage. During drying out the intrinsic protection may be impaired.
Connect only to a power supply with a voltage corresponding to that on the serial number label.
Connect only to power supply which provides a safety earth (ground) terminal.
Before moving, disconnect at the power supply socket. Do not remove the IEC connector.
Do not check the temperature by touch; use the temperature display or a thermometer.
To reduce the risk of eye injury during high temperature operation, use safety goggles or spectacles.
Do not touch surfaces which become hot during high temperature operation.
Ensure that the operating temperature is less than the maximum operating temperature of your
sample material.
Set the adjustable overtemperature cut-out after setting or changing the set temperature, and reset it
at monthly intervals to check that the cut-out is operating correctly.
Ensure that the mains switch is easily accessible during use.
Do not block or restrict ventilation slots.
If liquid is spilt inside the unit, disconnect it from the power supply and have it checked by a
competent person.
It is the user’s responsibility to carry out appropriate decontamination if hazardous material is spilt on
or inside the equipment.
Do not connect to a power supply or switch on before filling the tank.
Take care when topping up or draining, as the liquid in the tank may be very hot.
If the alarm lamp is illuminated do not touch the liquid or the heater, they may be very hot. Refill
carefully, a hot heater can cause a spattering of very hot water droplets and scalding steam.
Always use a lid when operating above 60°C. Take care when rising and removing the lid, it may be
hot. Steam and hot vapours can cause scalding.
Drain before moving the bath. Before draining allow the liquid to cool to below 50°C or heat to above
10°C.
Use only liquids specified in the operating instructions, within the specified temperature range. If the
alarm lamp is illuminated the liquid temperature may be above its recommended maximum: do not
inhale the vapours given off as they may be toxic; liquids should be safely discarded and replaced.

2 Getting Started
2.1 Unpacking
Remove the packing materials carefully, and retain for future shipment or storage.
2.1.1 Shaking bath - OLS200
The pack should contain:
shaking bath
trolley
drive magnet
drain insert (located in a clip on the rear panel of OLS200)
mains cable
these instructions.
2.1.2 Universal Tray
Tray fitted with springs for use with flasks.
2.1.3 Test Tube Tray
Tray for use with test tube racks.
2.1.4 Cooler - CS200G
Refrigerated immersion cooler, for operating temperatures down to 0°C.
2.1.5 Cooling coil - CW200
For operating temperatures at or below ambient, a Grant CW200 heat exchange coil can be used
to maintain the temperature at 2°C above the temperature of the coolant.
2.2 Installation
2.2.1 Location
Position the bath on a firm level surface with the controls facing the operator and adjust the
position of the feet so that the bath stands level. This can be done after filling with liquid to the top
of the trolley, and levelling the water against the top of the trolley as a reference. It is necessary
that the bath is level in order to achieve optimum performance.
2.2.2 for operating temperatures below ambient
The unit is insulated for use at temperatures below ambient. It is recommended that the gabled lid
is used to reduce heat gain.
To fit the cooling coil: remove the flask tray and trolley, then remove the base tray by undoing the
retaining 'N' nuts (see figures 1 and 5).
CS200G: Stand the CS200G next to the OLS 200 and position the cooling coil in the bottom of the
tank, ensuring that it lies flat, with the feed pipe at the rear.
CW200: Place the CW200 cooling coil in the bottom of the tank, ensuring that it lies flat, with the
input and output pipes at the rear.
To secure the cooling coil in position, replace the base tray and washers and tighten the four
retaining 'N' nuts (see figure 5).
Ensure that the CS200G is located so that the ventilation grilles are not less than 100mm from
any obstruction.
To use the lid: remove the slot cover and replace in the alternative position, to allow the
connecting pipe to pass through.
2.2.3 for operating temperatures above 60°C
At operating temperatures above 60°C a lid MUST be fitted. The Grant sloping stainless steel lid
directs condensate into the bath to prevent it from dripping into open flasks or tubes.

WARNING: ANTIFREEZE IS TOXIC. IT IS HARMFUL IF SWALLOWED.
READ THE SUPPLIERS’ HANDLING INSTRUCTIONS.
+5C to 99C
Water (taps or distilled). See maintenance and service section 7.
2.2.4 Fitting the trolley
Caution: The shaker uses a magnet located in the bottom of the tank. Once removed from the
bath the drive magnet produces a strong magnetic field and it should be placed in a position
where it cannot affect computer discs, cassettes, watches, etc. If your watch is susceptible to
magnetic fields, please remove it before removing or fitting the trolley. Once the trolley and drive
magnet have been fitted the stray magnetic fields are very small.
Fit the drive magnet onto the shaft in the bottom of the bath (see figures 1 and 2). Lower the
trolley into the bath, keeping it level, with the drive arm facing the front of the bath (see figure 4);
fit the drive arm pin into one of the holes on the drive magnet. See figure 1 and paragraph
3.1.3.2.2 for guidance as to which hole to select. If the drive arm is not parallel to the base of the
tank, it may be difficult to fit the pin into the hole.
2.2.5 Fitting the tray
The OLS200 shaking bath provides both linear and orbital shaking motion. Select the type of
motion you require by altering the position of the tray in the tank.
The tray is punched with a 'O' and a ' ' (see figure 3). For orbital motion, position the 'O'
nearer the front. For linear motion, position the ' ' nearer the front.
For orbital motion: tilt up the far end, locate the near end lip on the wheels nearest to you. Lower
the far end and move the trolley sideways until the pin locates in the hole in the drive arm (see
figure 4).
For linear motion: tilt up the far end, insert the near end lip between the locating strips on the
trolley (see figure 4). Lower the far end.
To remove the tray: hold both handles and keep the tray level as you lift it.
WARNING: For safety, do not remove the tray from the unit when the liquid is hot.
2.2.6 Filling
Before filling ensure that the drain pipe is not attached.
Fill the bath without the tray fitted, with approximately 9 litres of liquid. Fit the tray and adjust the
liquid level to the required immersion depth. When the liquid is level with the top of the tray the
flask immersion depth is 50mm.
DO NOT operate the bath without any liquid.
2.2.7 Specified liquids:
Do not use any other liquids without consulting Grant Instruments.
2.2.8 Connection to electrical supply
WARNING: The equipment must be earthed (grounded). It is protected by internal electrical
fuses. We strongly recommend that the power supply to any equipment for heating liquids should
include a residual-current circuit breaker (earth leakage trip).
Check that the voltage rating of the products, given on the serial number plate at the power cable
entry, is correct for your supply.
Fit the mains cable into the IEC power socket at the rear of the unit(s).
Connect the plug to the power supply socket.

3 Operation
3.1 OLS 200
3.1.1 Controls and indicator lamps
The temperature display normally shows the liquid temperature in C.
When the display set C button is pressed the set temperature is shown.
The temperature C control knob sets the required operating temperature.
Heater lamp (orange) indicates when the heater is on. While the bath is warming up, the lamp is
on continuously. As the temperature approaches set point, the lamp starts to flash, and continues
to flash intermittently while the unit is controlling at set temperature.
Alarm lamp (red) illuminates when the overtemperature cut-out has operated.
The overtemperature push to reset knob sets the overtemperature cut-out. The cut-out
operates if the liquid temperature rises above its set temperature. When it has operated, the red
alarm lamp illuminates and the heater is switched off. The temperature of the liquid continues to
be displayed to warn of possible high temperatures.
The speed display shows shaking speed in revolutions per minute. In linear motion the number of
strokes is twice the number displayed.
The shaking/min knob sets the shaking speed.
3.1.2 Setting the temperature
The display normally shows the liquid temperature. To show the set temperature at any time,
press the display set °C button. To set the required operating temperature, push the display set
C button, whilst turning the temperature °C knob until the required temperature is indicated on
the display.

3.1.3 Shaking
Switch on shaking. In linear motion the number of strokes/minute is double the number displayed.
To set the required revolutions per minute, turn the shaking/min knob until the required speed is
displayed. The speed rises slowly to the set value. Following adjustment, the setting should be
checked after several minutes. Stroke length for linear movement
The stroke length in linear motion can be altered according to your requirement with a choice of
three settings. The setting can be changed by altering the position of the drive arm pin in the drive
magnet (see figure 1). Hole ‘A’ sets the stroke length at 18mm; there are three alternative
positions of hole ‘A’, any of them may be used. Hole 'B' sets the stroke length at 28 mm and Hole
'C' sets the stroke length at 36 mm. See figure 1 for identification of holes.
Orbital motion operates ONLY at 9mm radius.
Maximum speed
The maximum speed depends on number and size of flasks, liquid depth, operating temperature
and, in linear motion, stroke length. The maximum speed will need to be determined for each
individual application. To determine the maximum speed, increase the speed until the trolley
begins to move erratically or stop; switch the shaking off, turn the speed down and restart. By
repeating this procedure the speed can be fine tuned to a maximum point, just below the point at
which it de-latches. The shaking trolley is driven by a drive magnet coupled to a rotating magnet
below the tank; as the speed is increased a point is reached where the magnetic coupling de-
latches, causing the trolley either to move erratically or to stop.
Liquid depth
Maximum speed is achievable with the minimum liquid depth.
Liquid depths up to a maximum of 130mm (90mm flask immersion) can be used, but water may
splash out at high speeds, particularly with a small number of large vessels.
Flasks, stroke length
The following table gives a guide to the maximum speeds obtainable with 50mm immersion
depth, three different stroke lengths and various sizes and numbers of Erlenmeyer flasks.

3.1.4 Setting the overtemperature cut-out
To protect both the unit and your samples, the overtemperature cut-out should be set each time
the required operating temperature is changed. Turn the overtemperature push to reset knob
fully clockwise and press to reset. The cut-out is now set at its maximum. Allow the bath to
stabilise at the required operating temperature. Turn the control slowly anticlockwise using a
screwdriver until the red alarm lamp comes on. Press the knob and gently turn clockwise until the
alarm lamp goes out. Turn the knob anticlockwise three quarters of the way back towards the
point where the alarm lamp came on. The overtemperature cut-out is now set approximately 10°C
above the required operating temperature.
Note: When the cut-out has operated, the bath needs to cool to below the set temperature before
the cut-out can be reset. Push the knob to reset the cut-out.
3.1.5 Draining
Allow the liquid to cool to below 60°C before draining. The drain connector is positioned on the
rear panel. The drain insert is fitted into a clip on the rear panel next to the drain connector.
Connect a suitable pipe to the drain insert. Place the end of the pipe over a drain or in a container.
Push the drain insert into the drain connector. The liquid will now drain from the bath. To remove,
press the button and pull out the insert. Replace in the clip.
3.2 CS200G
The mains (power) switch is on the rear of the unit.
Switch on at the rear. Always ensure that the bath is switched on to provide temperature control,
and that shaking is switched on at low temperatures, to prevent the formation of ice.
Do not switch on if:
- the temperature of the liquid in the bath is above 40°C
- the cooler has been tilted by more than 25° during the past six hours
- the interval since switching off the cooling system is less than 10 minutes
