1.1 Safety Instructions
y
Please carefully read all chapters of the Manual before any installation, operation, and
maintenance. To avoid personal injury and equipment damage, please be sure to operate
the product in accordance with the instructions in this Manual and the markings on the
cabinet.
yThe unit should only be moved by at least two people so as to guarantee safety.
yIn handling or removal of the equipment, please pay attention to its height and center of
gravity. When using a transportation tool for handling, it must be raised from the bottom to
avoid toppling.
yThe unit contains moving components. Be careful to keep it away from your arms, legs,
hair, clothes or jewelry so as to avoid any danger.
1.2 Installation Instructions
y
The unit can be connected with a single or dual power source. Make sure the input power

dangers and only qualified service personnel can operate the unit. Improper operation
may lead to serious injury or death or equipment damage. Be sure to follow all the instruc-
tions and warnings contained in the Manual.
yWhen replacing the side panels or front or back doors, make sure there is no foreign mat-
ter in the cabinet.

Chapter 3 : Installation
WARNING:
1. 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 injury.
2. The high voltage in the equipment is potentially fatal! The inner components have

3.1 Installation Site
When planning the installation site for the cooling unit, you must take the following into
FRQVLGHUDWLRQVRDVWRJXDUDQWHHWKHEHVWHI¿FLHQF\
yEnvironmental requirements: The installation site must allow the equipment to move in
DQGRXWWKHÀRRULQJPXVWEHDUWKHZHLJKWRIWKHHTXLSPHQWDQGWKHUHLVDVXI¿FLHQWVSDFH
for maintenance, operation, and pipe repair. The cooling unit can only be located indoors
and 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
loss of cooling capacity.
yHumidity and heat source: Implement water-proof and heat insulation engineering for the
indoor environment so as to isolate the outside humid hot air.
NOTE:
The unit cannot humidify or automatically de-humidify. If the humidity of the
installation environment exceeds the operation scope (refer to 4.3 Operating
Temperature and Humidity), the condensation of the water of the coil may lead to a
rise in the water level of the condensed water pan, triggering an alarm.
yNoise impact: At a high load, the operation of this cooling unit may produce loud noise.

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 (such as Figure 3-2) so as to
avoid damage to the casters.
4. The casters are only suitable for moving
RQÀDWVXUIDFHV$YRLGKHDY\IDOOLQJRI
and moving of the unit on uneven ground,
which may damage the casters or even
result in toppling.
5. When moving the unit, pay attention to its height and center of gravity. At least two
people working together should handle the unit so as to guarantee safety.
3.2 Space Reservation
In order to facilitate maintenance, operation,
and air circulation, please reserve a net
space around the equipment.
It is suggested to preserve 1200mm for the
front passage, 600mm for the rear passage
and at least 300mm above the cabinet for
pipe installation. If the pipeline adopts a lower
connection mode, the height of the raised

yLevelers
After moving the unit into place, use a
wrench to rotate clockwise the four levelers
be-side the casters to put them down and
stable on the floor. Make sure the unit
cannot slide or topple.
WARNING:
The levelers are only used for
leveling the unit and cannot be
used to compensate for the height
difference of the floor so as to
avoid toppling.
3.4 Positioning
After moving the unit into place and 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:
yCabinet fasteners
If the adjacent cabinets are Delta cabinets (MSR1110 and MSR2110), you may use
