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.

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).
