Page 8: Product Introduction
Product Introduction The CoolDoor precision cooling device (chilled water type) is an air conditioning product that must be installed in combination with an IT rack or any standard rack, and is capable of quickly removing and outputting hot air from the racks. It can achieve precise control through the internal heat exchanger, EC fan, chilled water ball valve, and PLC control. - Page 9 Hot aisle expansion • Disassembly and installation can be performed through the side panels of the CoolDoor to achieve sharing of the hot aisle and partial backup for adjacent CoolDoor- Rack systems. Lockable access door • The CoolDoor includes a locking mechanism to prevent unrelated personnel from opening it.

Page 34: Water Quality Requirements
In order to ensure the long-term and reliable operation of the CoolDoor, water quality control must be carried out for the piping system of the CoolDoor to prevent small particles from damaging the O-rings of the components, which can lead to poor sealing, the ball valve components being unable to be operated due to deposits, or even a decrease in the heat transfer effect due to the fouling of the inner surface of the coil. -

The following actions can only remove the air in the coil of the CoolDoor, and cannot ensure that the air in the closed chilled water system is completely removed. The air release valve should be used for automatic exhaust at the highest and most reasonable point of the closed circuit system. - Page 49 2. When making adjustments, the closed chilled water circuit should be in operation. Find the position of the exhaust valve on the CoolDoor, as shown in the figure below. Turn the cap to the right, and install the filling soft tube inlet with a switch on the position of the exhaust valve on the CoolDoor, as shown in the figure below.

Page 50: Water Volume Equilibrium
CoolDoors is relatively long, it is easy to cause water imbalance. Unbalanced water volume can easily cause insufficient water volume at the last of the CoolDoor; or when controlled by a 2-way control valve, it can cause drastic changes in the water volume of other CoolDoors, which will make the overall waterway system unstable. -

Page 73: Chapter 8 : Maintenance & Cleaning
Component Maintenance 1. Coil and door maintenance The CoolDoor does not have a filter to filter the air. The system will first cool the air through the coil and then send it out through the fan. Therefore, the coil can easily become blocked by dust from the air in the IT room. -
Page 74: Component Replacement
Component Replacement Before performing power-off maintenance, the main door of the CoolDoor should be opened. The server can use its own fan to dissipate heat to avoid poor heat dissipation for the server. When troubleshooting or replacing components, ensure that the CoolDoor power is correctly turned off. - Page 75 Figure 2, and take out the fan. Finally, remove the four screws around the fan motor at position 3 below with a screwdriver to separate the fixed plate from the fan. Install the new fan back onto the CoolDoor in the reverse order to complete the fan replacement.
