11.4 Commissioning Trial Runs
11.4.1 Commissioning test run of single refrigerant system
Once all the pre-commissioning checks in Part 3, 11.3“Pre-commissioning Checks” have been completed, a test run
should be performed as described below and a Amazon V Series System Commissioning Report (see Part 3, 12“Appendix
to Part 3 – System Commissioning Report”) should be completed as a record of the operating status of the system during
commissioning.
Note: When running the system for commissioning test runs, if the combination ratio is 100% or less, run all the indoor
units and if the combination ratio is more than 100%, run indoor units with total capacity equal to the total capacity of the
outdoor units.
The test run procedure is as follows:
1. Open the outdoor unit liquid and gas stop valves.
2. Turn on the power to the outdoor units.
3.
If manual addressing is being used, set the addresses of each indoor unit.
4. Leave the power on for a minimum of 12 hours prior to running the systemto ensure that the crankcase heaters have
heated the compressor oil sufficiently.
5. Run the system:
a) Run the system in cooling mode with the following settings: temperature 17°C; fan speed high.
b) After one hour, complete Sheet A of the system commissioning report then check the system parameters using
the UP/DOWN button on each outdoor unit’s main PCB and complete the cooling mode columns of one Sheet D
and one Sheet E of the system commissioning report for each outdoor unit.
c) Run the system in heating mode with the following settings: temperature 30°C; fan speed high.
d) After one hour, complete Sheet B of the system commissioning report then check the system parameters using
the UP/DOWN button on each outdoor unit’s main PCB and complete the heating mode columns of one Sheet D
and one Sheet E of the system commissioning report for each outdoor unit.
6. Finally, complete Sheet C of the system commissioning report.
11.4.2 Commissioning test run of multiple refrigerant systems
Once the commissioning test run of each refrigerant system has been satisfactorily completed as per Part 3,
11.4.1“
Commissioning test run of single refrigerant system
”, run the multiple systems that make up a project
simultaneously and check for any abnormalities.
