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.

3.1.1 Clearance Zone
Indoor unit
A minimum of 900 mm (36”) of clear floor space in front of and behind the equipment is
recommended for service access. All required normal maintenance is performed from the
front and rear of the equipment.
Unit: inch
(Figure 3-1: Indoor Unit Clearance)
It is recommended to preserve 47.2 inch in the front communication aisle, 23.6 inch in the
rear aisle, and at least 60 cm above the cabinet to facilitate wiring and piping.
23.6 in.47.2 in.

Outdoor unit
The outdoor unit will have a large amount of air flow that discharges heat into the
atmosphere. Therefore, the outdoor unit should be installed in a clean area free of
debris, away from dirt and foreign objects that may block the condenser. In
addition, the outdoor unit must not be located near steam, hot air or flue gas
outlets. The outdoor unit should be located more than 60 inches away from walls,
obstructions, or adjacent equipment, and there should be no obstructions above
the equipment.
Do not install the outdoor unit in an area where the sound level of the normal
operation of the equipment may interfere with the work or living environment of
others.
The installation surface must not muddy.

3.1.2 Handling
Before moving the equipment to the installation site, plan the route according to the following
instructions:
1. Make sure the passage, floor, elevator or slope on the handling route can bear the weight
of the equipment and handling device, and there is sufficient space to avoid collisions.
2. In the case of a slope on the handling route, its inclination must not be greater than 15
degrees so as to avoid toppling the cabinet.
3. The bottom casters are only suitable for short distance movement. For long distance
movement, use a handling device so as to avoid damage to the casters.
4. The casters are only suitable for moving on flat surfaces. Avoid heavy falling off and
moving of the unit on uneven ground since they may damage the casters or even result
in toppling.
5. When moving the unit, pay attention to its height and center of gravity. A minimum of two
people should work together to handle the unit so as to guarantee safety.

3.1.3 Remove the Transport Fasteners from the Compressor
(Figure 3-3: Removing the Side Panel)
If the side panel is locked, use a No. 2 Phillips screwdriver to remove the screws first. Hold
the side panel with your hand when the screws are being removed in order to prevent the
panel from falling. Then, pull outward first, then lift up to remove the side panel.
To place the side panel back in place, align it with the two bottom holes. One person should
support the side panel while the other person refastens the fixing screws.
After removing the side panel, please remove the compressor transport fasteners as shown
in the figure below (the compressor transport fasteners must be removed before operation,
if the transport fasteners are not removed, the compressor will easily generate abnormalities
in operation), and tighten the stud at a torque of 120±5kgf/cm2.
When moving the unit, the transport fasteners must be reinstalled.

InfraSuite R Series – Air Cooled Type 20
(Figure 3-4: Removing Transport Fasteners from the Compressor)
3.1.4 Positioning
After moving the unit into place and once it is parallel with the adjacent cabinet, you must
position it so as to ensure its stability. The following two methods can be used, depending
on the installation environment:
Cabinet fasteners
If the adjacent cabinets are Delta cabinets (MSR1110 and MSR2110), you may use
connecting fasteners to fix the equipment. Each cooling unit is provided with four
connecting fasteners (two at the front and two at the rear). You must remove the front
and back doors before installing the connecting fastener. Refer to the following
procedures:
Step 1
If the front door is locked, use the attached key to open it.
Step 2
Remove the unit’s earth wire and the control panel’s flat cable, raise the front door, and
take it out.
