Concrete Platform Scenario
3.1
1. According to the site space and device dimensions to decide the location of concrete platforms.
And mark the four reference points of concrete platforms using an ink fountain and measuring
tape.
•When marking the mounting positions for concrete platforms, ensure that the four lines form a rectangle.
•When the equipment is installed indoors, it is recommended that shock pads be installed
between the air duct and the floor.

3Securing the FusionCol8000-E
1. Read the related user manual before installing the device.
2. Ensure that the concrete platform levelness meets the requirements before installation.
3. The device must be installed strictly according to the heating ventilation air conditioning (HVAC)
equipment construction regulations.

2. Connect the steel hoisting ropes, and hoist
the device onto the concrete platforms.
3. Secure the equipment to the concrete platform using right angle brackets.
Grounding the FusionCol8000-E
3.3
•Ground lugs mode: Before the installation, remove the tinfoil from the ground lugs.
•Ground cables mode: Ground cables can be routed through plastic-coated metal hoses for
protection based on site requirements.

4Connecting Water Pipes
1. Connect the water pipes using thread connectors. The thread joints need to be sealed with raw
materials or thread adhesive.
2. Clean the external water pipes before connecting them to the water inlet and outlet pipes of the
coil pipes of the FusionCol8000.
3. Connect the water inlet and outlet pipes of the FusionCol8000 using thread connectors. When
connecting the water pipe, do not exert excessive force to prevent damage to the coil pipe.
(When connecting the pipes provided with the FusionCol8000, use two pipe wrenches or chain
pliers.)
4. Heat preservation measures must be taken at low temperatures to prevent water from freezing in
the water pipe.
5. The drainpipe must be wrapped with thermal insulation foam (including the buried parts).

(2) Spray drainpipe (DN40)
(3) Spray water refill pipe (DN20)
1. Installing Water Pipes
•The maximum
allowable installation
inclination of the
water seal is 15
degrees.
•Install the water seal
in strict accordance
with the preceding
figure to avoid
reverse connection.

6
Sealing putty
Paper protective film
2. Remove the paper protective film from the sealing putty.
3. Seal the gap between the water pipe and the equipment
using sealing putty after the pipe is correctly connected.
4. Condensate drainpipes and water refill pipes may freeze and thereby be blocked or crack in
low-temperature areas. Anti-freezing measures must be taken for the pipes.

(2) Electric heating belt
(3) Water refill pipe
(4) Drainpipe (The end needs to be
connected to the utility drainpipes.)
(5) Soil
5. Wrap the electric heating belt before wrapping the thermal insulation foam. The thermal
insulation foam must be able to withstand a temperature higher than 200°C.
5Installing Air Duct
Installing a Supply Air Duct
Dimensions of reserved holes for device
•The supply air duct needs to
be prepared onsite.
•Use six screws (M10 x 25) to
secure the horizontal board
and use three screws (M10 x
25) to secure the vertical
board.

Connecting Power Cables and Signal Cables
6.1
6Connecting Cables
1. All power cables and ground cables must
comply with local national standards.
2. For details about electrical ports, see the
FusionCol8000-E400 Modular Indirect
Evaporative Cooling System User Manual.
3. After connecting power cables and checking
cable connections, use sealing putty to fill in
the gap between the cables and the cabinet
(as shown in the right figure), and the sealing
putty can be obtained from the fitting bag.
•The return air duct needs to be prepared onsite.
•Use five screws (M6 x 12) to secure the
horizontal board and use three screws (M6 x 12)
to secure the vertical board.

Connecting Power Cables
The following figure shows the position of the return air temperature and humidity sensor in the
smart cooling product. The cable passes through the cable hole to remote T/H sensor. Set the
sensor positions based on their location and the following table.
(Optional) Connecting T/H Sensors Outside Cabinets
6.2
1. Connect the IN port on the first T/H sensor outside the cabinet to the RS485/12V port on the
main control board.
