The installation location of the equipment should ensure that the drainage system is unblocked. Improper drainage systems may cause poor drainage and cause equipment to get wet. The unit must be warmed up for two hours for the first time. This is to protect the compressor. If the preheating time is not met, the unit may report the oil preheating and the temperature barrier.

WARNING Never connect unclean pipe to the unit! If the unit is to idle for a long time, the water in the water system shall be drained to prevent the plate heat exchanger being iced. If the unit is to idle for a short time, the power-off is not allowed, because the unit has automatic anti-freezing function.

Basic requirements The chilled water pipelines may be connected as per relevant procedure when the unit is installed in place. Such pipelines shall be free from any foreign matter, and must conform to local piping regulations and rules. Before unit operation, thoroughly flush all chilled water pipelines to ensure that they are free from any foreign matter.

conditioning part load operation; Energy-saving technical measures should be adopted as much as possible in the design of air-conditioning piping systems; The pipe and fittings used in the piping system should meet the local requirements; Pay attention to the maintenance and management of the piping system design, easy to operate and adjust.
◆ Water system volume calculation example Assume that two CA0065EANR module units are installed in a water system, and the return water temperature is set to 12 degrees. The main pipe diameter is DN65. The total length of the inlet and outlet pipes is 80m.
Users must not remove and add control components privately. Haier Company shall not be liable for any damage to the unit and personal injury caused by failure to operate in accordance with these Rules.
Maximum current Starting current Reference cable cross section CA0065EANR 5X10mm Note: The working voltage of the unit must be within ± 10% of the rated working voltage. If the wiring distance of the power supply line is too long, the power cable diameter should be increased. It is recommended to refer to the technical information of the cable manufacturer under the guidance of a professional electrician.
