Draining the Waterbath
Warning:
Do not set a temperature during this process. Doing
so may result in damage to the heater.
Insert the drain hose in the drain connector on the front left of
the bath. The bath will completely drain approximately 42 L (11
gal).
Guidelines for Cleaning the Waterbath
It is recommended that the bath be cleaned in place.
With a little water in the bath use a soft cloth and wipe the
inside of the bath. Rinse the bath with water and let it drain to
remove foreign material. The better the bath is cleaned the
longer it will stay clean.
Do not use coarse or abrasive materials. They may scratch the
bath. Alcohol based products can cause the bath to crack.
Warning:
The use of chemicals may damage the waterbath
and will not be covered by the warranty.

of the height gauge.

Heater and Temperature Probe Adjustment

Place an NIST traceable thermometer next to the
temperature probe, or in the exit port on the left side
