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:
0 to + 5

C 80% water, 20% antifreeze (inhibited ethylene glycol)
WARNING: ANTIFREEZE IS TOXIC. IT IS HARMFUL IF SWALLOWED.
READ THE SUPPLIERS’ HANDLING INSTRUCTIONS.
+5

C to 99

C Water (taps or distilled). See maintenance and service section 7.
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.
