(1) Mount a pressure gauge on the low pressure
service port.
(2) Reset the operation using the remote
controller, and then restart the operation.
Is the stop
valve open?
- The low pressure sensor is normal, and outdoor unit main PCB is
also normal.
- The low pressure has really become low.
Replace the outdoor unit main
PCB (A1P).
Replace the low pressure sensor.
(S1NPL)
Open the stop valve.
CHECK 2
Caution
Be sure to turn off the power switch before connecting or disconnecting
connectors, or parts may be damaged.
Eliminate factors that cause the low pressure to decrease.
CHECK 12
(
1) Use the table on
CHECK 12
to
convert the voltage measurement into
pressure measurement.
Compare the
voltage measurement of
the connector of the pressure
sensor (
1) with the measurement
of the pressure gauge.
Are the characteristics of the
low pressure sensor
normal?
Connect the service checker, and then compare the low pressure value
measured by the service checker with the voltage measurement of the
connector of the pressure sensor (
1)
Service Checker
CHECK 12
Are both
pressure values the
same?
YES
NO
Eliminate the indoor unit error.
Any
indoor unit errors?
(Other than
E4
in the error
history of the remote
controller?)
