Figure 3-9 Installing outdoor unit on top of the cabinet
Note
1. The outdoor unit should be installed in the place where the maintenance is easy. Do not install it at the bottom level in public
site and should be away from residential area.
2. The outdoor unit should not be directly placed in the environment with a high requirement for noise.
3. To ensure the cooling effect, the outdoor unit should be placed in a clean place and should be away from dusts and alien
objects to avoid blocking the heat exchanger.
4. The outdoor unit should not be placed near the vapor, hot gases or waste gases.
5. The outdoor unit should be at least 450 mm away from the wall, barriers or neighboring equipment.
6. The outdoor unit should not be installed in the placed with snows at the air inlet and air exhaust sides.
7. You need to prepare a base that can withstand the weight of the outdoor and the base should be at least 50 mm above the
surrounding floors, and should be higher than the outdoor base by 50 mm (see Figure 3-8).
8. The weight of the outdoor unit is about 43kg. When you remove the outdoor unit from the rack and lift it to the top of the
cabinet, take care to avoid dropping or damaging the equipment.
9. This air conditioner is professional equipment and can only be used in SmartCabinet system and cannot be sold alone. Its rated
power is higher than 1kW, complying with the IEC61000-3-2 standard.
Connecting Copper Pipes
1. General Principles
1) The indoor unit and outdoor unit are connected via a copper pipe, and the connectors are quick-connecting screw-
thread connectors of English system. When the pipe length exceeds the standard length (see Table 3-1) and when
the direct copper pipe is used, you can use the welding mode.
2) Be sure to comply with the industrial standard in selecting and constructing the pipes, system vacuuming, and
refrigerant charging (the refrigerant is only needed when the pipe is too long). The refrigerant for this air conditioner is
R410A, and the charging amount is 1.3 kg.
3) The pressure drop along the pipes and oil return of compressor should be considered to avoid leakage and
blocking to maximally reduce the noise and vibration.
4) If it is necessary to extend the pipe assembly, or if the equivalent length exceeds 20m, it is necessary to add a
check valve at the outlet of the liquid pipeline of the condensation device. If the vertical height difference between
indoor and outdoor units exceeds the values shown in Table 3-1, please consult the manufacturer whether the pipe
extension kit or replace thick pipe diameter copper pipe is needed.
