Test Run - Hitachi air Core 600 Installation & Maintenance Manual

NOTES:
1) Follow local codes and regulations when sizing field wiring, and all the above are the minimum size.
2) The wire sizes marked in the table are selected at the maximum current of the unit according to
IEC 60335-1 or national/regional standards. Use the wires which are not lighter than the ordinary
polychloroprene sheathed flexible cord (code designation H07RN-F).
When the connecting the terminal block using flexible cord, 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.
When connecting the terminal block using a single
core wire, be sure to perform curing.
3) When transmission cable exceeds 15 meters, a larger wire size should be selected.
4) Use a shielded cable for the transmitting circuit and connect it to ground.
5) In the case that power cables are connected in series, add each unit maximum current and select wires below.
*In the case that current exceeds 63A, do not connect cables in series.

8. Test Run

● Only after all the checking points have been checked the unit can be operated.
(A) Check and make sure that the resistance of the terminal to ground is more than 2MΩ, otherwise, you
cannot operate the unit before the electricity leakage point is found and repaired.
(B) Check and make sure that the stop valve has been opened before operating the unit.
(C) Make sure that the electric power has been turned on for 6 hours before operating the unit.
● Make sure the power and unit run well then plug in.
● Turn on the appliance and adjust it to Cooling or Heating mode according to the room temperature.
Set at lowest temperature in cooling mode and highest temperature in heating mode.
Check if the appliance can run well.
● Installation of the appliance is generally finished after the above operations are done. If you still have any
trouble, please contact local technical service center of our company for further information.
● Pay attention to the following items while the system is running.
(A) 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 90 .
(B) Do not push the button of the magnetic switch (ES). It will cause a serious accident.
(C) Use remote controller to operate ,and check whether room temperature and function well.
After test, turn off the electric power.
