(4) In the case of SV5b (Bypass valve)
This solenoid valve closes when energized (when the relay is on).
It turns off for 3 minutes after defrosting ends and turns off during the heating-only or heating-main operation when SV9 is ON
and the value of 63HS1 is greater than 3.5 MPa [507 psi] even if the frequency becomes the minimum.
If you measure the temperature of the pipe downstream of SV5b while the valve is in the non-energized state, you can deter-
mine whether or not the valve is open from the corresponding change in temperature. When the valve is open, high-temper-
ature gas refrigerant passes through the pipe so do not attempt to check the pipe temperature by touching the pipe.
(5) In the case of SV7 (Bypass valve)
This solenoid valve opens when energized (when the relay is on).
This is on during the heating-only or heating-main operation.Confirm the operation from the LED display and solenoid valve
operation sound.
(6) In the case of SV9 (Bypass valve)
This solenoid valve opens when energized (when the relay is on).
It turns on during the heating-only or heating-main operation when the value of 63HS1 is greater than 3.5 MPa [507 psi] even
if the frequency becomes the minimum.If you measure the temperature of the pipe downstream of SV9 while the valve is in
the non-energized state, you can determine whether or not the valve is open from the corresponding change in temperature.
When the valve is open, high-temperature gas refrigerant passes through the pipe so do not attempt to check the pipe tem-
perature by touching the pipe.
(7) In the case of SV10 (Bypass valve)
This solenoid valve opens when energized (when the relay is on). It turns on during the Continuous heating mode.
If you measure the temperature of the pipe downstream of SV10 while the valve is in the non-energized state, you can deter-
mine whether or not the valve is open from the corresponding change in temperature. When the valve is open, high-temper-
ature gas refrigerant passes through the pipe so do not attempt to check the pipe temperature by touching the pipe.
(8) In the case of SV11 (Bypass valve)
This solenoid valve opens when energized (when the relay is on). It turns on during the Continuous heating mode.
If you measure the temperature of the pipe downstream of SV11 while the valve is in the non-energized state, you can deter-
mine whether or not the valve is open from the corresponding change in temperature. When the valve is open, high-temper-
ature gas refrigerant passes through the pipe so do not attempt to check the pipe temperature by touching the pipe.
