Detailed procedures will vary from chiller to chiller but this guide is intended to indicate the principle items to be checked on any Daikin chiller to ensure that the commissioning process is adequate It is not exhaustive and could be added to if necessary particularly where optional accessories are included Whilst all chillers are run at the factory this is only a brief functional test and it does not remove the need for all relevant commissioning checks to be carried out The procedures are in approximate chronological order Once delivered to site ensure that the installation instructions are followed carefully particularly the correct lifting and moving of the unit spacing from walls and other chillers pipework connections etc Check the correct positioning of anti vibration mounts if fitted and check that any devices for transportation are removed Make a close visual inspection of the chiller for transport damage and general condition Inform the Service Department at Daikin Europe of any problems Carry out a refrigerant leak check of the whole unit report and fix any leaks Check that there is a suitable strainer in the water pipes to the evaporator that the pipes are purged of air and that at no time does the water flow exceed 120 of the design figure Check that the main power cables have been installed correctly with the correct phase rotation with no mechanical strain on the terminals and correctly glanded in the ele
