4. Setup

Follow these steps to set up your water bath heater:

1. Unpacking: Carefully remove the water bath heater and all accessories from the packaging. Inspect for any damage during transit.
2. Placement: Place the unit on a stable, level, and heat-resistant surface in a well-ventilated area. Ensure there is sufficient space around the unit for air circulation.
3. Fill with Water: Open the lid and fill the inner chamber with distilled or deionized water. Do not overfill; ensure the water level is below the top edge of the chamber, leaving enough space for displacement by samples.
4. Lid Placement: Place the lid back onto the water bath. Adjust the rubber rings in the openings as needed to accommodate your containers.
5. Power Connection: Connect the provided power cord to the power inlet on the unit and then plug it into a grounded 110V AC power outlet.

5. Operating Instructions

This section details how to operate your Fockety water bath heater.

1. Power On: Flip the main power switch (usually located on the side) to the 'ON' position. The digital display will illuminate.
2. Setting Temperature (ST):
   • Press the 'SET' button on the control panel. The 'ST' (Set Temperature) value will start flashing.
   • Use the 'Up' (▲) and 'Down' (▼) arrow buttons to adjust the desired temperature.
   • Press 'SET' again to confirm the temperature setting. The unit will begin heating to the set temperature.
3. Setting Timer:
   • Press the 'TIME' button. The timer value will start flashing.
   • Use the 'Up' (▲) and 'Down' (▼) arrow buttons to set the desired operating time in minutes (0-999 minutes). If set to '0', the unit will operate continuously.
   • Press 'TIME' again to confirm the timer setting. The timer will start counting down once the set temperature is reached.
4. Monitoring Operation: The 'PV' (Process Value) display shows the current water temperature, while 'ST' shows the set temperature. The 'OUT' indicator typically shows when the heating element is active.
5. Placing Samples: Once the water reaches the desired temperature, carefully place your samples (in appropriate containers) into the water bath through the openings.
6. Power Off: After use, remove your samples, then flip the main power switch to the 'OFF' position. Allow the unit to cool down before cleaning or draining.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your water bath heater.

• Draining Water: After each use or regularly, drain the water from the bath using the drain valve. This prevents stagnant water and potential algae growth.
• Cleaning the Inner Chamber: Clean the stainless steel inner chamber regularly with a mild detergent and a soft cloth or sponge. Rinse thoroughly with distilled water. Do not use abrasive cleaners or sharp objects that could scratch the surface.
• External Cleaning: Wipe the exterior of the unit with a damp cloth. Avoid getting water into the control panel or electrical components.
• Descaling: If using tap water or if mineral buildup (scale) occurs, descale the inner chamber periodically using a suitable descaling solution designed for stainless steel, following the product's instructions.
• Storage: When not in use for extended periods, ensure the unit is clean, dry, and stored in a cool, dry place.
