Page 6: Pipeline Installation
The connecting copper pipe must be wrapped with insulation material (the thickness is usually more than 10mm, and the enclosed wet area is appropriately thickened). 3.3 AHU EXV boxes Model BL-SP-AHU05 BL-SP-AHU10 BL-SP-AHU20 BL-SP-AHU30 Inlet pipe size of liquid pipe Ø... - Page 7 AHU Kit 3.5 Typical recommended pipeline installation schemes There are diversified installation schemes for AHU kit that is matched with the multi-split air conditioner and AHU. Aiming at different sizes of AHU heat exchangers, structure forms of heat exchangers, the number of inlet and outlet pipes of heat exchangers, the configuration and control of AHU fans, using requirements on actual users, etc., there are different combination and installation methods, where there are different using effects.
- Page 8 blaubergventilatoren.de 2. Second installation diagram of pipelines, communication lines and sensors The installation methods are generally applied to the capacity of AHU below 120 HP, and one AHU Kit only needs to be selected. However, the boxes for the EXV matched with the capacity of AHU shall be connected in parallel, and the coils of all electronic expansion valves shall be controlled by this AHU Kit.
- Page 9 AHU Kit 4. Fourth installation diagram of pipelines, communication lines and sensors The heat exchangers of AHU for which the installation methods are generally applied are divided into multiple ones, each heat exchanger is connected into a set of individual system using a set of outdoor units and is connected in parallel with 1 box for the EXV or multiple EXV boxes to match with the capacity, and each set of system may be equipped with either 1 or multiple AHU Kit.

When selecting the target room ambient temperature computing control or 0-10V control, T1 sensor is working as the return air temperature sensor of the indoor unit, which is installed at the air return vent of the indoor unit for detecting the return air temperature of the indoor unit. The difference between the ambient temperature T1 and the set temperature of the indoor unit affects the capacity demand of the indoor unit to the outdoor unit: In cooling mode: When the return air temperature T1 of the indoor unit is below set temperature, the indoor unit will stop Indoor capacity demand will be 0;...

Page 12: Electrical Connection
blaubergventilatoren.de 4. ELECTRICAL CONNECTION 4.1 Electrical Wiring ATTENTION! The air conditioner shall use special power supply, and the power supply voltage shall meet the rated voltage. The external power supply circuit of the air conditioner must have grounding wire, and the AHU power supply ground wire should be reliably connected with the external grounding wire. - Page 13 AHU Kit 4.3 Wiring suggestions for signal wires between outdoor unit and AHU Kit 1. Signal wires must adopt shielded cables. Using other conducting wires may cause signal interference, resulting in malfunction. 2. The shielding layers of all shielded wires are twisted into one strand and connected to the “E” end of the terminal block (see the figure below). 3.
