5Installing Water Pipes
•The water pipes are connected using thread connectors. The threaded joints must be sealed
with sealing tape or thread adhesive.
•Clean the external water pipes before connecting them to the water inlet and outlet pipes.
•Connect the water inlet and outlet pipes of the FusionCol8000-E using thread connectors.
When connecting the water pipes, do not exert excessive force to prevent damage to the
pipes. (When connecting the pipes, use two pipe wrenches or chain pliers.)
•At low temperatures, take thermal insulation measures to prevent water pipes from
freezing.
•Water pipes must be wrapped with thermal insulation foam (including the buried pipes).
Designed water trap height
It is recommended that height
B be a smaller value.
1. Remove sheet metal for drainpipes.
2. Install the condensate water pan
drainpipe, evaporator condensate
water pan drainpipe, and water tank
drainpipe.

•The example describes how to install an indoor
air supply duct in the FDC scenario.
•The entire air duct must be wrapped with thermal
insulation foam. The thickness of the thermal
insulation foam must be at least 3 cm.
•The joint between the air duct and the unit
should be sealed to prevent air leakage.
Generally, sealing form should be applied to the
flange edge of the air duct or sealant should be
applied to the flange edge after installation.

The T/H sensors outside the cabinet are used to detect the temperature and humidity of remote
points. The installation position can be determined based on the site requirements. It is
recommended that the sensors be deployed near heat sources, or near places that lack cooling
capacity. Place the T/H sensors outside the cabinet near the cabinet. The sensor cannot face the
air outlet of the device.
(Optional) Connecting T/H Sensors Outside the Cabinet
8.2
1. Connect the IN port on the T/H sensor outside the cabinet to the RS485/12V port on the
main control board.
2. Connect the OUT port on the T/H sensor outside the cabinet to the IN port on the next
T/H sensor outside the cabinet in series.
3. Set DIP switches of the T/H sensors.
After the addresses are set, power on the device, choose Settings > System Settings > T/H
Sensor on the home screen, and set the sensors in the aisles corresponding to the addresses to
Enable. Otherwise, the sensors will not work.
