Notes of Installation, Operation

1、Attention to Points When Set The Basis of The Cooling Tower
1）cooling tower part of the foundation online at the same level. The basis of the level a bit high or low of the occasion, please fill-chip adjustment.
2）connecting rooms and plural occasions, make sure the room is no gap between.
3）the cooling tower Loaded on the basis, please fixed locking bolts basis. When Trial run, please re-confirm the basis of the locking bolts. On the basis of a steel frame, please locking steel bolts.
4）with anti-vibration mountings, make sure the foundation or a steel frame and anti-vibration mountings and cooling towers are locking, and anti-vibration mountings essentials assembly manual to confirm.

2、Notes of Piping and Pump
1）When Install Piping, please do not correct of the cooling tower piping ontology or interface deformation and don’t processing cooling tower parts. Otherwise it will affect the structural strength of the cooling tower.
2）The piping, valves should be installed below the water level in the cooling tower, otherwise will inhalation of air when run the beginning, and when stop running, it will have a spillway.
3）The connection with cooling tower make full use of soft joints, so that only piping vibration will not affect the cooling tower.
4）Please assemble the valve in the piping. This can be easily cleaning cooling towers, is also available on the run stopped, as anti-freeze responses. In order to make easy to operate, please do not in cooling towers below the valve assembly.
5）Consider the placement of equipment, the pump head should be sufficient, consideration should be given along the way the pressure loss and cooling coil pressure loss;
6）cooling fluid pressure flange interface is designed to 1Mpa, all pipe hanger or support should be considered.

3、 Notes of Debug Run
1） Blower motor please click on the arrow marking the direction to run the wiring.
2） Please re-confirm switch, fuse, wiring is in accordance with the capacity of the motor configuration. Single-phase motor running will burn, we recommend the use of over-current protection device.
3） Circulating water pump before the first run, in the pump to stop when the water filled piping. Open valves, start pumps, slowly open the valve. If you open the valve to start water pump, water will damage the impact of cooling tower components. Note the water level in the lower part of the sink run until all the water piping. Mains water use up until the bottom of the sink running water and stability to continuous operation. At this time, please note not to let the Department of respirable air filters. The use of terms such as measuring the volume of water running water, and the use of regulating valves adjust water flow perspective. If load, start the pumps, and began to cycle together with the load. If disturbed from time to time increase the load of water will lead to the entrance of the water temperature is abnormally high.
4） The upper part of tank water level will cause an imbalance of insufficient cooling capacity, please use piping with valve or valves to regulate the water level in the tank.
5） Please adjust the water level float ball valve to run.
6）electric heater with antifreeze, please take care not to air caused the fire burning.
7）Piping fortifications left behind by welding slag, cut the iron pipe on the freezer is very detrimental to the brass, but also so that the causes of deterioration of water quality, please clean pipeline trial run period.
8）The use of closed cooling tower of the occasion, recycled water distribution piping is closed tube, in order to be able to afford the expansion of the water pipe, set up expansion of water storage tanks, pressure tanks used for the following 0.49MPa.
9）Confined pumps cooling towers, in the hand after turning power.
Other, please click [cooling Tower maintenance manual] operation.

4、Note of Winter Run-time
Winter run-time with the outside temperature decreased, the proportion of air, the current value of blower motor gradually increasing, please pay attention to.
1）placed the heater in the bottom of the tank to prevent frozen water, please mounted thermostat, so that the water temperature does not rise to high temperature.
2）To prevent air heating, make sure that if some heat electric heater immersed in water , then electricity. Recommend the use of water-level alarm or detection switch.
3）electric heater on the other use, please refer to "cooling tower electric heater to prevent freezing operations manual" for use.
4） added a little antifreeze to the water. to prevent the circulating water in the cycle to antifreeze . in accordance with the type, concentration of antifreeze, cooling tower performance may change, please note when selected.
5）As a result of leakage and other reasons, this will result in lowering the concentration of unfrozen liquid, please regularly check the concentration, if necessary, please add.
6）to allow recycled water to maintain a certain degree of heat load, and ensure the cycle of water temperature do not less than 7 ℃ (the southern region can not be less than 3 ℃), in order to ensure the heat load ,please adding electric heating tube browser in the bypass piping system; while maintaining closed systems have a minimum flow of recycled water.
7）freezing water pipes: in order to ensure that cooling tower make up water pipes and outdoor supply, water pipes back to normal work in the winter, the need for these pipeline insulation, generally available with temperature control devices on the hotline to carry out with hot, electrical Hotline outsourcing of non-absorbent heat insulating material (such as flame-retardant polystyrene, etc.).
8）winter outage need empty the tank coil and the circulating water to prevent frozen, Frost Crack coil. What you hit open water valve can easy to put clean water.
