5.3.2Filling With Fluid

The CTR –80 Bath is not provided with a fluid. Depending on the desired tem- perature range, any of the following fluids, as well as others, may be used in the bath:

•Water

•Ethanol (Ethyl Alcohol)

•Ethylene glycol/water

•Mineral oil

•Silicone oil

•Halocarbon 0.8

Fluids are discussed in detail in Section 8.1.

Remove any access hole cover from the bath and check the tank for foreign matter (dirt, remnant packing material, etc.).

Fill the bath with clean unpolluted fluid. Fill the bath carefully through the large square access hole to a level that will allow for stirring and thermal ex- pansion. DO NOT turn on the bath without fluid in the tank. The fluid should never exceed a height of 1/2" below the top of the tank or be less than 2 inches
