Installation
WARNING: The equipment must be earthed (grounded). It is protected by 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 plate next to the power cable
entry, is correct for your supply.
Fit the mains cable appliance coupler into the IEC socket at the rear of the unit, situated near to
the mains (ON/OFF) switch.
Connect the mains cord plug to the supply mains socket outlet.
Switch ON to operate the refrigeration immersion coil. Ensure that the bath is correctly setup and
operating to achieve the required temperature control, and to prevent the formation of ice.
Do not switch ON if :
-
the temperature of the liquid in the bath is above 100°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
-
Note: condensed water vapour from the surrounding ambient air will dilute the water/glycol mixture and
eventually cause ice to form on the immersion coil. Any ice build-up should be removed, and the transfer
medium liquid replaced. The cooling power will be reduced if the ice is permitted to continue to build-up on
the coil.
