3.1 Installation Site
When planning the installation site for the cooling unit, you must take the following into con-
VLGHUDWLRQVRDVWRJXDUDQWHHWKHEHVWHI¿FLHQF\
yEnvironmental requirements: The installation site must allow the equipment to move in
DQGRXWWKHÀRRULQJPXVWEHDUWKHZHLJKWRIWKHHTXLSPHQWDQGWKHUHLVDVXI¿FLHQWVSDFH
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
KXPLGLW\LQWHUIHUHQFH7KHRXWVLGHKXPLGLW\HQWU\PXVWEHPLQLPL]HGLQDFFRUGDQFHZLWK
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: ,IWKHKXPLGLW\RIWKHLQVWDOODWLRQHQYLURQPHQWH[FHHGVWKHRSHUDWLRQVFRSH
(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.
7KHUHIRUHLWLVQRWVXLWDEOHWRLQVWDOOWKHXQLWFORVHWRRI¿FHV
yInput power: In connecting the power supply, make sure that the power conforms to the
UDWHGYDOXHDQGWKHSRZHUGLVWULEXWLRQGHYLFHLVVXI¿FLHQWWRVDWLVI\WKHORDGUHTXLUHPHQW,Q-
spect the rated values of each unit and make sure they have been properly grounded. One
branch circuit or power distribution device can only be connected with one cooling unit.
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

3.3 Handling
yHandling Instructions
Before moving the equipment to the installation site, plan the route according to the follow-
ing 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 a sufficient net 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 dis-
tance movement, use a handling device
(such as Fig. 3-2 Forklift handling) so as
to avoid damage to the casters. (Fig. 3-2: Forklift handling)

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.
yLevelers
After moving the unit into place, use a wrench to rotate clockwise the four levelers beside

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 instal-
lation environment:
yCabinet fasteners
If the adjacent cabinets are Delta cabinets (MSR1110 and MSR2110), you may use con-
QHFWLQJIDVWHQHUVWR¿[WKHHTXLSPHQW(DFKFRROLQJXQLWLVSURYLGHGZLWKIRXUFRQQHFWLQJ
fasteners (two at the front and two at the rear). You must remove the front and back doors
before making the fastener connection. Refer to the following procedures:
1
If the front door is locked, use the attached key to open it.

Use the key to unlock the rear door, remove the earth wire, raise the door, and take it
out. The rear door is of the split type and, if necessary, take down both doors.
NOTE: Put the front and rear doors that have been removed in a safe place so
as to avoid any equipment damage or personal injury due to collisions.

Use a screwdriver to loosen the screw below the fastener and lock it on the adjacent
cabinet.
