Test Operation
SiBE37-701
166
Test Operation
1.2.5.2.1 Procedure of Adding Refrigerant charging
1. Make sure the following works are complete in accordance with the installation manual.
Piping work
Wiring work
Air tight test
Vacuum drying
Installation work for BS, indoor unit
2. Calculate the “additional charging amount” using “How to calculate the additional refrigerant
to be charged” in
“6 Example of Connection”
3. Open the valve B (
See figure below.
The valve A,C and the liquid pipe, suction gas pipe,
HP/LP gas pipe shutoff valves must be left closed), and charge the refrigerant of the
“additional charging amount” from the liquid side shutout valve service port.
REYQ8~16PY1B
4. If the “additional charging amount” was charged fully, close the valve B and go to step 6.
If the “additional charging amount” was not charged fully, close the valve B and go to step 5.
5. Perform the refrigerant charging following [Automatic refrigerant charging operation
procedure] as shown below. And charge the remaining refrigerant of the “additional charging
amount”.
Note:
z
For performing the automatic refrigerant charging operation, the push button on the PC-
board (A1) of outdoor unit are used. (See page 165.)
And the refrigerant are charged from the refrigerant charge port via the valve A. (See above
figure.) For operating the push button and opening or closing the valves, follow the
procedure.
z
During Automatic refrigerant charging operation, the system will select charging mode
(cooling mode or heating mode) by the temperature condition as follows.
When charging in cooling mode, the system will stop operation when the required amount of
refrigerant is charged.
During charging in heating mode, a person must manually close valve A and stop operation.
Beforehand, check the remaining refrigerant that is needed to charge based on the
“additional charging amount” in step 2 and the charged amount in step 3.
z
The refrigerant will be charged about 30kg in one hour at outdoor temp. 30°C DB (about
12kg at outdoor temp. 0°C DB).
z
During Automatic refrigerant charging operation, you can stop the operation forcedly by
pushing MODE button (BS1).
