Things To Check After Completing The Installation - Samsung AM JXVHGH Series Installation Manual

Things to check after completing the installation

1 . Before supplying the power, use DC 500 V insulation resistance tester to measure the power (3 phase: R, S, T/ 1
phase: L, N) terminal and the outdoor unit grounding .
- Measurement should be over 30MΩ .
2 . Before supplying the power, use a voltmeter and phase tester to check the voltage and the phase .
- R, S, T, N terminal: check if the voltage is within 380-415 V between wires (R-S, S-T, T-R) and 200-240 V between
• Never measure the communication terminal since communication circuit may get damaged .
• Check for short-circuit of the communication terminal with a general circuit tester .
CAUTION
230V 230V 230V
400V 400V
400V
3 . Check if the R-410A indoor units are connected .
4 . When N phase is not correctly connected to R, S and T phase, over-voltage protection control will be in effect and it
will cut-off the power of the PCB . Check the power cable connection of the N phase if the PCB is not turned on .
5 . Check the following after the installation is completed .
• Have you checked the external surface and the inside of the outdoor unit?
Outdoor • Is there any possibility of short-circuit caused by the heat of an outdoor unit?
unit
• Is the place well-ventilated and ensures space for service?
Installation
• Is the outdoor unit fixed securely to withstand any external force?
work
• Have you checked the external surface and the inside of the indoor unit?
Indoor
• Is there enough space for service?
unit
• Have you checked if the center of the indoor unit is ensured and it is installed horizontally?
• Have you selected correct pipes?
• Are the liquid and gas valve open?
• Is the total number of connected indoor units within the allowable range?
• Are the length and the height difference between the refrigerant pipes within the allowable range?
Refrigerant pipe • Are the branch joints properly installed?
work
• Did you check the connection of liquid and gas pipes?
• Have you selected correct insulator for pipes and insulated them correctly?
• DId you insulate the pipes and connection part correctly?
• Is the quantity of the additional refrigerant correctly weighed in? (You must record the amount of additional refrigerant
on the service record paper placed inside of the outdoor unit . )
• Have you checked if the drain pipes of the indoor and outdoor unit are connected together?
Drain pipe work • Have you completed the drain test?
• Is the drain pipe properly insulated?
• Are the power cable and communication cable tightened firmly on the terminal board within the range of rated
tightening torque?
• Have you checked for cross-connection of the power and communication cables?
Electrical wiring
• Have you performed the earthing work 3 to the outdoor unit?
work
• Did you make sure to use 2-core cable (not multi-core cable) for the communication cable?
• Is the length of the wire within allowed range?
• Is the wiring route correct?
• Did you set the address of the indoor and outdoor units properly?
Setting address
• Did you set the address of the indoor and outdoor units properly? (When using multiple remote controllers)
Option • If there is a possibility of the outdoor unit from vibrating, check whether the anti-vibration frame is correctly installed .
