Trane CXAU - Water System Installation

Installation- Mechanical
15PKGP-SVX19A-EN
Snow Protection
1. For the installation in the area where there is more snow, it is necessary to raise the unit, and install snow covers to make
sure unit running normally.
2. During heavy snowfall, please check the round-tube-plate-n heat exchanger, if the heat exchanger is covered by heavy
snow, manually clean the snow is needed.
Water System Installation
Pipeline Prefabrication Requirements
1. The pipe diameter of the inlet and outlet of the water system should not be smaller than the size of the joints to the unit.
2. The connections between the pipeline and water pump or air conditioning unit must use exible pipes to avoid the
transmission of vibration.
Pipeline Installation Requirements
Water pipeline connections should comply with relevant installation procedures, and all water pipes must comply with local
piping codes and regulations. Please refer to the schematic diagram for the installation of typical accessories for water
systems. Please strictly abide by the following water system pipeline installation requirements, otherwise it may a󰀨ect the
normal operation of the unit, even warning occurs or unit damaged.
1.
Water owrate:
The water owrate of the water system must be designed by professionals, to guarantee the water
owrate through the water-side heat exchanger of the unit matches the water owrate required by the unit, otherwise the
heat exchange performance will degrade and a󰀨ect the performance of unit or even bring to unit alarm or shutdown. When
all the terminal FCUs are shut o󰀨 or only one FCU is running, keep the unit running stably for some time to check whether
the water owrate meets requirements. If not, adjust the piping resistance or water pump heads until requirements are met.
