Page 2 Onsite Preparations Gas pipe requirements when the NetCol5000-A035 and NetCol500-A080 Man- Refrigerant are used together: outer diameter of 7/8 inch (22.22 mm) ; thickness of datory pipe 1.2 mm; operating pressure ≥ 4.5 MPa Gas pipe requirements for other models: outer diameter of 3/4 inch (19.05 mm);...
Page 3 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) .

(Optional) Installing an Air Baffle When the NetCol5000-A025 is used with the NetCol500-A060, if the outdoor unit cannot be installed against a wall or the local outdoor temperature is below –15°C, place an air baffle at the air intake side of the side-mounted outdoor unit. Connecting the Refrigerant Pipe Laying the Engineering Pipe 1.
Page 9 Discharging Nitrogen Exhaust nitrogen from three needle valves for the indoor unit and one needle valve for the outdoor unit. When exhausting nitrogen, do not remove the valve plug in case of losing or damaging it. 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.

Page 17 b) Connect teamwork and monitoring communications cables. The teamwork modes include FE teamwork and CAN teamwork. FE teamwork is recommended. FE teamwork support point-to-point communication, long-distance cascading, and group upgrade. If the number of units in a group is greater than 16, FE teamwork needs to be implemented by group.
Page 18 FE Teamwork + RS485 Monitoring Networking Teamwork Monitoring Protocol MAC_CAN Modbus-RTU It takes 3 x n seconds to collect data from n units. If the time required for the host to collect data from all units does not meet the performance requirements, group the units.
Page 19 CAN Teamwork + FE Monitoring Networking Teamwork Monitoring Protocol Modbus-TCP/SNMP One teamwork network supports a maximum of 32 units. On the Teamwork Settings screen of the Description display modules of the first and last units, set Enable teamwork CAN resistor to Yes. If the Modbus-TCP/SNMP protocol is used, customers can purchase the NetEco (a LAN switch is required) or a third-party NMS as the monitoring system.
