quickly close valve A and follow instructions as described below.
CAUTION
When adding refrigerant is done or when

pausing, close the valve on the refrigerant tank
immediately.
More refrigerant might be charged by any
remaining pressure after the machine is stopped.
The outdoor fan may keep rotating a little bit

more, but this does not indicate a malfunction.
Case 1: Charging complete
H1P H2P H3P H4P H5P H6P H7P
Charging of the refrigerant is complete. Press BS1 MODE
button once and go to step 5.
Case 2: Recharging operation
H1P H2P H3P H4P H5P H6P H7P
Press BS1 MODE button once and perform automatic
refrigerant charging again starting from Step 4.2.
Case 3: Charging interrupted
H1P H2P H3P H4P H5P H6P H7P
Something is preventing normal operation:
 Is the gas side stop valve completely open?
 Are the valve on the refrigerant tank and valve A open?
Check if the BS4 TEST button was pressed within 10
minutes after the valves were opened.
 Is the indoor unit air intake vent or outlet vent blocked?
After correcting the problem, press BS1 MODE button once and
perform automatic refrigerant charging again starting from
step 4.2.
Case 4: Failure
H1P H2P H3P H4P H5P H6P H7P
(a) An error in the system interrupted the operation of the unit. Check the
error by using the error code displayed on the remote controller. For an
explanation of the error codes, see "Error codes on the remote controller"
on page 20 and solve the problem.
After correcting the problem, press BS1 MODE button once and
perform automatic refrigerant charging again starting from
step 4.2.
When charging is complete, determine the weight of refrigerant
that was added and fill in the amount in the "Additional
refrigerant charge label" attached to service precautions plate on
the unit.
After adding the refrigerant, do not forget to close the lid of the
service port. The tightening torque for the lid is 11.5~13.9 N•m.
