Frequently Asked Questions

1. How does the 208-240V power supply affect the heating output?
The heating capacity is voltage-dependent. It provides 1.6 kW when running on 208V, increases to 2.0 kW on standard 230V, and reaches its maximum of 2.1 kW when connected to a 240V supply.

2. What is the difference between the KISS K6 and the KISS K6s?
While both share the same bath and temperature range, the KISS K6s (2008.0044.98) features a slightly higher cooling capacity (0.26 kW at 20°C) compared to the standard KISS K6 (0.20 kW at 20°C).

3. Can I use the KISS K6 for external applications?
Yes, the KISS K6 is equipped with M16x1 pump connections at the rear, making it suitable for the temperature control of external closed systems like refractometers or small condensers.

4. Is the refrigeration system air-cooled or water-cooled?
The KISS K6 is air-cooled, meaning it uses an internal fan to dissipate heat. This makes it easy to set up as it does not require a cooling water connection, though it does require adequate ventilation space.

5. Is this unit safe to use with flammable bath fluids?
Absolutely. It is rated Safety Class III (FL) per DIN 12876, which includes the necessary adjustable overtemperature protection and low-level sensors specifically for safe operation with flammable liquids.
