AFTER INSTALLATION
AHU-KIT Installation Check
1) Ensure that Control-KIT is correctly installed.
• You can choose the built-in type or auxillary type depending on installation environment.
• Ensure that the Control-KIT cables are correctly connected.
• Control-KIT should be fireproofed and avoid direct sunlight upon installation.
(Especially for individual type)
• Avoid installing the unit in a location exposed to direct sunlight or rain.
• Do not install the Control-KIT in or on the outdoor unit.
2) Ensure that EEV-KIT is correctly installed.
• Ensure that EEV-KIT can be installed inside or outside, but do not install the EEV-KIT in residential areas.
• When EEV-KIT is installed separately outside of the AHU, insulate the pipe to prevent the dew condensate.
• Ensure that IN/OUT pipes are correctly connected.
• Ensure that the body of EEV-KIT is installed in level.
• Make sure that EEV-KIT is installed where condensation can be drained well.
• Do not install the EEV-KIT in or on the outdoor unit.
3) Ensure that IN/OUT sensor is correctly attached.
• IN sensor should be attached after the distributor, on the coldest part of the heat exchanger piping.
Ensure that the sensor is insulated.
• OUT sensor should be installed approximately 200mm behind the header of AHU heat exchanger.
Test Operation
1) Before turning the power on, use DC 500V insulation tester to check the power terminal (L,N)
and the earthing on AHU-KIT.
• Resistance value should be over 30MΩ.
2) Test the voltage of power(L, N) before turning on the power.
• Insulation tester may damage the communication circuit.
• Communication terminal should be tested with ordinary circuit tester to check the short circuit.
N
220V
L
3) Check the list below after installation and make sure the AHU-KIT units are properly operating.
• Installation environment (resistance level etc.)
• Refrigerant leak test
• Power cable
<ELB>
• Insulation on refrigerant pipe.
• Drainage
• Circuit breaker connection and earthing
• Normal system operation
