Precautions for seasonal recovery of water-cooled screw chillers
1. Carry out maintenance inspections according to the operation and maintenance regulations of auxiliary equipment manufacturers such as water pumps and cooling towers;
2. Close the drain valve (or screw on the screw plug) on the water system, open the shut-off valve on the main circuit of the water system, open the exhaust valve on the water system, pour the required water volume for the water system, and close the vent valve after the gas is removed ;
3. Check whether the relevant parts on the electrical circuit are loose, whether the contactor and other suction operations are free, whether the insulation package is damaged, and blow up the accumulated dust;
4. Close the main power switch to send power to the starter cabinet to confirm that the compressor lubricating oil has been heated for more than 8 hours;
5. Start and run the water-cooled screw chiller in the order that the unit is started daily.
Please strictly follow the above operations, otherwise the normal operation of the water-cooled screw chiller cannot be ensured, and even its service life will be reduced to a certain extent!
