Hitachi RAS-4.0PNNBDH1 - Wireless Remote Controller Operations; Wireless Remote Controller Buttons and LCD Symbols

Do not operate the system until all the check points have been cleared.
(A) Check to ensure that the stop valves of the outdoor unit are fully opened.
(B) Check to ensure that the electric wires have been fully connected.
(C) Check to ensure that the electrical resistance is more than 2MΩ, by measuring the resistance between ground
and the terminal of the electrical parts. If not, do not operate the system until the electrical leakage is found and
repaired.
Trial run function identification
Turn ON the appliance to proceed trial run.
Pay attention to the following items while the system is running.
Do not touch any of the parts by hand at the discharge gas side, since the compressor chamber and the pipes at the
discharge side are heated higher than 194℉ (90℃).
Trial run should be performed after refrigerant piping,drain,wiring,etc. have been finished.
The air conditioner is provided with a crankcase heater, check to ensure that the switch on the main
power source has been ON for more than 6 hours ahead of power on preheating, otherwise it might
damage the compressor!
·Turn off the power after trail run is finished.
Installation of the appliance is generally finished after the above operations are done. If you still have any trouble,

1. When connecting the terminal block using stranded wire, make
sure to use the round crimp-style terminal for connection to the
power supply terminal block. Place the round crimp-style
terminals on the wires up to the covered part and secure in place.
2. When connecting the terminal block using a single core wire, be
sure to perform curing.
