4 Quick Start

Set up of the bath requires careful unpacking and placement of the bath, install- ing the drain valve, filling the bath with fluid, and connecting power. Consult Section 5 for detailed instructions for proper installation of the bath. Be sure to place the bath in a safe, clean and level location. Install the drain valve onto the pipe fitting at the back of the bath and make sure the valve is closed. See Section 5.3, Bath Preparation and Filling. Be sure to place the bath in a safe, clean and level location.

Fill the bath tank with an appropriate liquid. For operation at moderate bath temperatures, clean distilled water works well. For lower temperatures, ethanol (denatured) works well but is NOT USABLE AT HIGHER TEMPERA- TURES due to flammability.

Carefully pour the fluid into the bath tank through the large rectangular access hole above the tank avoiding spilling any fluid. The fluid must not exceed a height of 1/2 inch below the top of the tank or be less than 2 inches below the top.

4.3Power

Plug the bath power cord into a mains outlet of the proper voltage, frequency, and current capability. See Section 3.1, Specifications, for power details. Refer to and read the CAUTION at the front of this manual concerning brownout and over voltage protection.

Turn the bath on using the front panel “POWER” switch. The bath will turn on and begin to heat or cool to reach the previously programmed temperature set-point. The front panel LED display will indicate the actual bath tempera- ture. Set the cooling switch to “OFF” for temperatures above approximately 50°C. Set the switch to “ON” for lower temperatures. When the cooling switch has been turned on, the first stage compressor will power up. The second stage will come on automatically when proper conditions are met. This will take 2 to 4 minutes. Cooling in the bath will not begin until the second stage starts.

4.4Setting the Temperature

In the following discussion and throughout this manual a solid box around the word SET, UP, DOWN or EXIT indicates the panel button to press while the dotted box indicates the display reading on the front panel. Explanation of the button function or display reading is written at the right.

To view or set the bath temperature set-point proceed as follows. The front panel LED display normally shows the actual bath temperature.
