Chapter 3 : Installation
WARNING:
Only service personnel can perform the following installation procedures. No
installation, piping or handling should be performed without authorization so as to
avoid equipment damage and personal injuries.
WARNING:
The high voltage and high-pressure refrigerant in the equipment can be fatal! The
inner components can potentially be dangerous, and only qualified service
personnel can perform wiring and piping.
For detailed information on installation, refer to the installation manual. The user
manual contents are for reference only.
3.1 Location and Power Considerations
When planning the installation site for the cooling unit, you must take the following into
consideration so as to guarantee the best efficiency.
Room Preparation: The installation site must allow the equipment to move in and out, the
flooring must have sufficient bearing capacity, and there must be sufficient space for
maintenance, operation, and pipe layout and repair. The indoor environment must be
isolated from the outside air to avoid temperature and humidity interference. The outside
humidity entry must be minimized in accordance with the local or national regulations so as
to avoid the increase of operation costs due to temperature differences increasing the heat
load temperature.
Humidity and heat source: Implement water-proof and heat insulation engineering for the
data hall environment so as to isolate the outside humid hot air.
NOTE:
If the humidity of the installation environment exceeds the operation scope, there
may be excessive coil condensation, since the standard model of this equipment is
unable to humidify or dehumidify. This equipment comprises of a highly sensible
heat design. With a low load or poor air-tightness, excessive humidity is likely; use
auxiliary dehumidifying equipment in these situations.
Noise impact: At a high load, the operation of this cooling unit may produce loud noises.
Therefore, it is not suitable to install the unit close to offices.
Incoming Power Supply Requirement: When connecting the power supply, make sure
that the power conforms to the rated value, and that the power distribution device is sufficient
to satisfy the load requirement. Inspect the rated values of each unit and make sure they
have been properly grounded. Do not connect more than one cooling unit to the same branch
circuit or power distribution equipment.
