Page 3 Refrigerant R410A Do not use inferior refrigerant. Otherwise, Huawei has no responsibility for the damage caused by the inferior refrigerant. Refrigerant Authenticity Verification Method: 1. Dial the hotline of the refrigerant producer to confirm its reliability. 2. Put the refrigerant indoor for 24 hours. Then use a thermometer to measure the external surface temperature of the refrigerant cylinder (figure 1) , and connect a pressure gauge to the cylinder to measure its internal pressure (figure 2) .

Page 7 Vertical Installation Unit: mm (Optional) Installing the Water Cooling Module Installation environment: enclosed indoor environment in which the temperature and humidity can be controlled within the ranges of 4℃ to 45℃ and 5% RH to 90% RH respectively. If the indoor installation position is ventilated, it should be more than 5 km away from the sea or pollution sources (such as salt lakes, chemical plants, mineral plants, thermal power plants, and coal mines).
Page 8 4. When the indoor unit is higher than the outdoor unit, the maximum height difference is 8 m. When the indoor unit is lower than the outdoor unit, the maximum height difference is 30 m. 5. When welding pipes, ensure that the pipes are dry. You are recommended to weld the pipes between the indoor and outdoor units, then connect the two ends of the pipe to the indoor unit and outdoor unit.
Page 9 Welding the Indoor Unit Ports Take protective measures, such as spreading a piece of wet cloth, around the welding position, to avoid burning the bottom panel, top panel, side panel, internal components, needle valves, other pipes, thermal insulation foam, power cables, labels, and tags.
