Operating Test SiE18-201
160 Operating Test
1. Record the installation location of each BP unit in the centralized name plate attached to the front panel (2) of the indoor unit.
2. Open the liquid/gas closing valves.
3. Check for improper wiring and piping.
With a remote controller, start the cooling operation in one single room only.
(Operating condition: indoor/outdoor temperature of –5˚C or higher)
Set the temperature to 18˚C.
After operating for 5 minutes, check that the temperature difference between inlet and outlet of the indoor unit is 8˚C or higher.
Likewise, perform the above step with all indoor units.
If some improper wiring or piping is found, correct them, and then check again.
* Before the operation check is completed on one unit, start the operation of the next
indoor unit to be checked so that some
trial operation time
can be saved. (If the trial operation is performed on every indoor unit one by one,
since the compressor
is stopped after each operation, it will
take some time to restart for the next operation.)
4. After checking for improper piping and wiring, record the installation locations of indoor units
the wiring name plate
attached to the BP main body.
5. After checking that all the piping and wiring is done properly, start the trial operation in heating mode.
With a remote controller, perform the heating operation for all rooms. (Set the temperature to 32˚C.)
After operating for 60 minutes, check that the temperature difference between inlet and outlet is 15˚C or higher.
6. Upon completion of the trial operation, stop the operation for all rooms with the remote controller.
Note: 1. When performing a trial operation, check that the indoor/outdoor temperatures satisfy the following conditions:
Cooling: –5˚C or higher
Heating: 25˚C or lower
2. For the pump down procedure, refer to the trouble diagnostic name plate attached to the front panel (2).
