Inspection and test operation
Checking FCU KIT installation
y Check if FCU KIT is installed properly.
y
– Check if cables of FCU KIT are properly connected.
– Check if FCU KIT is installed vertically or horizontally.
– Install FCU KIT avoiding condensation area and water pipe line.
– Tighten wire holder to fix power and communication cable.
– Check if the locations of FCU KIT sensor and valve is appropriate.
– Check if the location of sensor is placed at inlet and the sensor is attached to the pipe.
Trial operation
1 Before supplying the power, use DC 500 V insulation resistance tester to measure the
insulation resistance of power (L, N) terminal and FCU KIT grounding.
y Measurement should be over 30 MΩ.
y
CAUTION
• Do not measure the communication terminal as the communication circuit can be
damaged.
• Use common circuit tester on communication terminal to check open or short.
AC 208 - 230 V~ 60 Hz, 1 Ph
AC 220 - 240 V~ 50 Hz, 1 Ph
2 Check the power voltage (L, N) before supplying power and then turn on the switch.
3 After completing the installation, check the followings to make sure FCU KIT operates
without a problem.
