Operation Sequence of Water Chiller
1.CHECK LIST BEFORE INPUT POWER
WHEN the power supply and water supply both meet the requirements,then can we input the power:FIRST, press the power button ON, and check :
① LIQUID LEVEL AND OPEN THE PUMP VALVE:
Whether the liquid level of the cold water tank meets the requirements and whether the front and rear valves of the cold water pump have been opened;
② OPEN THE WATER TOWER AND PUMP
Turn on the switch of cooling water tower and cooling water pump, and pay attention to the opening of inlet and outlet valves of cooling water. (Note: air cooled type does not need cooling water tower)
③CHECK THE TURNING DIRECTION
When all the above conditions are met, you can use the inching mode to test whether the direction of cooling water pump, cold water pump, cooling tower fan and condensing fan of air cooling unit is correct, and whether the water transmission and air suction and discharge are normal. If not, they must be eliminated first.
2. PRESS THE CHILLER OPEN BUTTON AND LET IT RUN
Turn on the running switch of the chiller again, and the chilled water pump starts to run. Please note that the inlet and outlet valves of the chilled water must be opened, and the compressor will run automatically after the delay switch. Please check and adjust the required temperature.
3. Startup sequence difference of water-cooled and air-cooled chiller:
① Water cooled chiller unit:
turn on the cooling tower fan and cooling water pump first, and then turn on the chiller
② Air cooled chiller unit:
can be started directly
4. Shutdown sequence:
① Water cooled unit:
turn off the chiller first, then turn off the cooling tower fan and cooling water pump
② Air cooled unit:
It can be shut down directly.
