Trial operation
Before the unit is turned on, test the resistance between the power block terminal (L, N terminals) and
the earth. If it is below 1M , it can't allowed running.
Turn on the outdoor unit. To protect the compressor during start-up, it should be switched on 12 hours
before the trial run.
Never operate the electromagnetic contactor manually for forced trial run.
Before operation
Trial operationing method
(it is dangerous when the protection device does not work.)
Refer to the service manual for the running procedure.
When the unit fails to start under room temperature, try forced trial run by the following steps.
Cooling
Heating
Set the running mode to "Cooling"
Press the ON/OFF button till an "L" blinks at the "Setting temp" area of the wire controller LCD
and "Auto" is displayed at the fan speed area. Now the unit enters into cooling trial run.
Set the running mode to "Heating"
Press the ON/OFF button till a blinking "H" and an "Auto" sign appear on the wire controller. Now
the unit enters into heating trial run.
During forced trial run, working modes cannot be changed through the remote controller.
After trial run, press the ON/OFF button to stop the unit.
Indoor unit installation
The unit shall be installed according to the
specifications to resist to strong wind and earthquake.
Improper installation may cause dangers of unit
falling down etc.
After selecting the unit installation location, proceed the following steps:
1. Drill a hole in the wall and insert the connecting pipe and wire through a PVC wall-through tube
purchased locally. The wall hole shall be with a outward down slope of at least 1/100. (See
Figure 2)
2. Before drilling check that there is no pipe or reinforcing bar just behind the drilling position.
Drilling shall avoid at positions with electric wire or pipe.
3. Mount the unit on a strong and horizontal building roof. If the base is not
firm, it will cause noise, vibration or leakage.
4. Support the unit firmly.
5. Change the form of the connection pipe, connection wire and
drain pipe so that they can go through the wall hole easily.
The unit shall be installed at locations enough
to support the unit. If not, the air conditioner
may fall down and cause personal injury.
