Operation
1.
Connect the water bath to an alternating current supply of voltage specified on the rating plate.
2. Ensure the water level is above the elements. On boiling baths connect the constant level device to a
water supply and drain.
DANGER: THIS WATER BATH MUST NOT BE CONNECTED TO A DIRECT POWER SUPPLY
3.
Switch the MAINS on then Turn the simmerstat/thermostat or temperature controller up using the up or
down keys only as required.
4. An indicating lamp ‘OP1’ will flash when the heaters are operating.
5. Ensure the manual reset over heat cut off (brown button below the controller) is set by pressing it in or that
the over temperature alarm AL4 is set above the desired operating temperature (depending on which is
present).
Safety Overtemperature cutoff ­ manual reset button
If the water bath is fitted with a manual reset button, be sure this is depressed before use. If the water level is too
low or runs out the switch will pop out and turn the heaters off until the reset is depressed.
If the water bath is fitted with an inbuilt over heat safety alarm it must be set to slightly above the desired setpoint
temperature and will prevent overheating. Change the ALM4 value to slightly above the setpoint temperature as set
out in the instruction page. The Alarm will be activated if the bath reaches the ALM4 value or if the sensor is
broken or damaged. To restart the bath to heat, acknowledge the alarm by pressing the page and scroll keys
simultaneously (left two keys on key pad together for 1 second only).
