9-3. Outline of the determination diagram
The first determination of whether a defective part is in the hydro unit or the outdoor unit can be performed by the
following method.
9-3-1. Procedure of defect diagnosis
In the case of a defect, please apply the following procedure in order to find the defective part.
9-3-2. How to determine from the check code on the remote
control
If the defect is limited by the check code displayed on the remote control, please repair the defect based on the
table on the next page.
The check codes are separated into two groups: software and hardware errors.
Since a hardware error cannot be cancelled without a part replacement etc., please perform a repair.
If its abnormality is determined, the abnormality is noticed by indicating the check code on the remote control check
code display part while sounding off a buzzer.
9-3-3. How to cancel a check code on the remote controller
(1) Press or button (on the operation side) to clear the check code.
(2) Press to stop a buzzer for an abnormality only.
Although the above procedure cancels the check code, the hardware error will be displayed again until the
hardware repair is completed.
