Recirculating cooler between 80℃ and 90℃. Silicone oil is applied commonly when temperature range over 90℃. Warning Bath liquid over 35℃ should not be directly cooled via cryogenic circulator. That is, the compressor could not start when the temperature of the bath is over 35℃. 3.2 Controller Panel Above is the picture of the unit’s controller panel: There are two 4-digit LED displays. - Page 9 Recirculating cooler There are 8 keys on the controller panel, which are Pump key , Menu , Left-shift key , Add key , Reduce key , Esc key , Enter and Start/Stop key There four indicators function as following: Low water level alarm. No water flow alarm. Warning Red light flashes Protection delay alarm.

Recirculating cooler 3.3 Operation guide 3.3.1 Switching on 1. Turn on the leakage protector. 2. Turn on the power switch. Then the unit begins to initializing interface. When initializing finished, the unit enters standby mode with a buzzer beep; 3. Press Start/Stop key. Check the fluctuation of the outlet pressure gauge and the vibration of the pump. - Page 11 Recirculating cooler directly or Menu key indirectly. 1. Single-point high precision mode: This mode is to control the water temperature of the bath in a constant value T00 via PID algorithm. The unit under this mode can also work under the Start/Stop economic mode by setting R_CS and R_CM parameters (please refer to Part 3.4 for details).

Recirculating cooler adjusting temperature. Ordinarily it is about 15 to 20 minutes. 3.3.6 Switching off 1. Press Start/Stop key to stop the compressor, the system enters into standby state, then press Pump key to turn off then pump. 2. Switch off the power supply of the control panel; 3. - Page 15 Recirculating cooler I for details). 1) Input code 0022 to enter into operation model base. The first interface: the auxiliary display shows R_AM, which is the code for automatic start with power on; the main display shows setting parameter, 0 stands for automatic start, 1 for manual start, 2 for remote control switch, 3 for remote communication control.
