9. Test run
9.4. AUTO RESTART FUNCTION
Indoor controller board
This model is equipped with the AUTO RESTART FUNCTION.
When the indoor unit is controlled with the remote controller, the operation mode, set temperature, and the fan speed are memorized by the indoor controller board. The auto
restart function sets to work the moment the power has restored after power failure, then, the unit will restart automatically.
Set the AUTO RESTART FUNCTION using the remote controller. (Mode no.01)
10. Easy maintenance function
Maintenance data, such as the indoor/outdoor unit's heat exchanger temperature and compressor operation current can be displayed with "Smooth maintenance".
* This cannot be executed during test operation.
* Depending on the combination with the outdoor unit, this may not be supported by some models.

* Stable mode will take approx. 20 minutes.
3 [Fig. 10-0-3] (P.11)
The operation data will appear.
The Compressor-Accumulated operating (COMP. run) time is 10-hour unit, and the Compressor-Number of operation times (COMP. On/Off) is a 100-time unit (fractions
discarded).

C Liquid pipe
D Gas pipe
E Stop valve
F Outdoor unit
G Refrigerant gas cylinder operating valve
H Refrigerant gas cylinder for R410A with siphon
I Refrigerant (liquid)
J Electronic scale for refrigerant charging
K Charge hose (for R410A)
L Gauge manifold valve (for R410A)
M Service port
1. Connect gas cylinder to the service port of stop valve (3-way).
2. Execute air purge of the pipe (or hose) coming from refrigerant gas cylinder.
3. Replenish specified amount of refrigerant, while running the air conditioner
for cooling.
Note:
In case of adding refrigerant, comply with the quantity specified for the refrigerating
cycle.
Caution:
• Do not discharge the refrigerant into the atmosphere.
Take care not to discharge refrigerant into the atmosphere during installation,
reinstallation, or repairs to the refrigerant circuit.
• For additional charging, charge the refrigerant from liquid phase of the gas
cylinder.
If the refrigerant is charged from the gas phase, composition change may
occur in the refrigerant inside the cylinder and the outdoor unit. In this case,
ability of the refrigerating cycle decreases or normal operation can be
impossible. However, charging the liquid refrigerant all at once may cause the
compressor to be locked. Thus, charge the refrigerant slowly.
To maintain the high pressure of the gas cylinder, warm the gas cylinder with warm
water (under 40 °C [104 °F]) during cold season. But never use naked fire or steam.
