3. Installation
WARNING:
1. Only service personnel should perform the following installation procedures. To avoid equpment damage and
personal injury, do not perform unauthorized installation, piping or handling.
2. The equipment's high voltage is potentially fatal! Only qualified service personnel should access inner
components or perform wiring.
3.1 Installation Site
When planning the cooling unit's installation site, consider the following for the best efficiency.
y y
Environmental requirements: The installation site must allow the equipment to move in and out, the flooring must bear the weight of
the equipment and there must be sufficient space for maintenance, operation, and pipe repair. The cooling unit can only be located
indoors. The indoor environment must be isolated from the outside air to avoid temperature and humidity interference. Outside
humidity entry must be minimized in accordance with local or national regulations to avoid the increase of operating costs due to loss
of cooling capacity.
y y
Humidity and heat source: Implement waterproofing and heat insulation engineering for the indoor environment to isolate the unit from
outside hot, humid air.
Note: The unit cannot humidify or automatically de-humidify. If the humidity of the installation environment exceeds the operational scope (refer to
4.4 Operating Temperature and Humidity), the condensation of the water in the coil may lead to a rise in the water level of the condensed water
pan, triggering an alarm.
y y
Noise impact: During maximum output, the operation of this cooling unit may produce fan noise in excess of 60 dB. Therefore, it is not
suitable to install the unit close to offices.
y y
Input power: In connecting the power supply, ensure the power conforms to the rated value and the power distribution device is
sufficient to satisfy the load requirement. Inspect the rated values of each unit and ensure they have been properly grounded. Only use
one branch circuit per cooling unit.
3.2 Placement
In order to facilitate maintenance, operation, and air circulation, please
reserve a net space around the equipment.
Allow 1200 mm (47 in.) space for the front, 600 mm (27 in.) space for the
rear, and at least 300 mm (12 in.) above the cabinet for pipe installation. If
the pipeline adopts a lower connection mode, the height of the raised floor
should not be lower than 300 mm (12 in.). If the pipeline adopts an upper
connection mode, the equipment can be set on a common floor.
