ELECTRICITY SUPPLY
Before connecting to the electricity supply please familiarise yourself with the parts of the manual relevant to your
model.
Your unit's supply voltage requirement is specified on a plate on the instrument along with the serial number. All Fast-
Cal units will work on an electricity supply frequency of 50Hz or 60Hz. The apparatus is provided with an approved
power cord. If the plug is not suitable for your location then the plug should be removed and replaced with an
appropriate plug.
Take care to ensure the old plug is disposed safely.
The cable is colour coded as follows:
COLOUR
FUNCTION
Green/yellow
Earth (Ground)
Brown
Live (line)
Blue
Neutral
Please ensure that your unit is correctly connected to the electricity supply.
THE APPARATUS MUST BE CORRECTLY EARTHED (GROUNDED)

IMPORTANT - READ THIS NOW!
CHILLERS
If supplied these devices should be left to settle for 24 hours before use with the flexible hose in an upright position.
This will allow the internal oil to return to its correct position if it has been disturbed during transit.
SETTING UP
The whole manual should be carefully read before using the bath, and then set the bath up as follows.
Connect the drain pipe to the drain tap and the overflow pipe to the side overflow pipe. Place a suitable container
under the overflow pipe. Ensure the tap is shut, i.e. lever at 90° to the tap body. If the equalising block is to be used it
should be placed in position now.
Fill the bath with suitable liquid, water is probably best for initial testing. Fill the bath until the level is 10mm below the
top of the round central calibration tube
ALWAYS ISOLATE THE BATH FROM THE SUPPLY WHEN CHANGING LIQUIDS
Turn the flow control to the mid position.
