(2) Exhaust Air
After adding water for the first time or replacing water, exhaust the air in the water pump
to start use, otherwise the equipment will be damaged. The exhaust method is as follows
：
Method 1: Under the state of shutting down, after adding water, remove the water outlet
and connect the water pipe, drain for 2 minutes, and then install it firmly.
Method 2
：
Open the water supply inlet, after starting the machine (water flows),
repeatedly press and fold the water pipe several times to drain the air from the pipe.
8.Test-run Check.
(1) Check whether the pipeline connection is correct, and there must be no bubbling or
water leakage;
(2) Check whether the inlet and outlet water ball valves are open and the drain valve is
closed;
(3) Check the liquid level of the water tank;
(4) Confirm that the electrical wiring of the equipment is connected correctly;
(5) Confirm whether the equipment is grounded.
V. Operating States &Parameters Adjustment
The new T-506D intelligent temperature controller is designed with intelligent control
mode. It will self-adjust controlling parameters according to room temperature for meeting
equipment cooling requirements.
The new T-506E intelligent temperature controller is designed with constant temperature
control mode with water temperature maintained at 25
℃
.Users can adjust it as needed.
T-506D and T-506E controllers are of same functions and structure except factory setting.
1.Temperature control panel introduction
2.Indicators of temperature controller working status
Refrigeration indicator - During refrigeration process, this indicator is on. In constant
temperature control mode, this indicator is off. During the delay process, this indicator
flashes.
Refrigerant solenoid valve indicator - When connected, this indicator is on. When
disconnected, this indicator is off.
Heating indicator - When connected, this indicator is on. When disconnected, this
indicator is off.
Alarm indicator - When connected, this indicator is on. When disconnected, this

3.Quick setting
Press “SET” key to set the temperature. The upper window indicates F0 (F1 is indicated
in intelligent control mode) while the lower window flashes with current value. Then press
or key to change the value which will be memorized by the temperature
