WARNING<br />
Insulator check<br />
Ventilation<br />
Be attentive to<br />
electric shock<br />
Compulsion<br />
Check after repair<br />
After the work has finished, be sure to use an insulation tester set (500V Megger) to<br />
check the resistance is 2MΩ or more between the charge section and the non-charge<br />
metal section (Earth position).<br />
If the resistance value is low, a disaster such as a leak or electric shock is caused at user’s<br />
side.<br />
When the refrigerant gas leaks during work, execute ventilation.<br />
If the refrigerant gas touches to a fire, poisonous gas generates.<br />
A case of leakage of the refrigerant and the closed room full with gas is dangerous because<br />
a shortage of oxygen occurs. Be sure to execute ventilation.<br />
When checking the circuit inevitably under condition of the power-ON, use rubber<br />
gloves and others not to touch to the charging section.<br />
If touching to the charging section, an electric shock may be caused.<br />
When the refrigerant gas leaks, find up the leaked position and repair it surely.<br />
If the leaked position cannot be found up and the repair work is interrupted, pump-down<br />
and tighten the service valve, otherwise the refrigerant gas may leak into the room.<br />
The poisonous gas generates when gas touches to fire such as fan heater, stove or cocking<br />
stove though the refrigerant gas itself is innocuous.<br />
When installing equipment which includes a large amount of charged refrigerant<br />
such as a multi air conditioner in a sub-room, it is necessary that the density does<br />
not the limit even if the refrigerant leaks.<br />
If the refrigerant leaks and exceeds the limit density, an accident of shortage of oxygen is<br />
caused.<br />
For the installation/moving/reinstallation work, follow to the Installation Manual.<br />
If an incorrect installation is done, a trouble of the refrigerating cycle, water leak, electric<br />
shock or fire is caused.<br />
After repair work has finished, check there is no trouble.<br />
If check is not executed, a fire, electric shock or injury may be caused.<br />
For a check, turn off the power breaker.<br />
After repair work (installation of front panel and cabinet) has finished, execute a test<br />
run to check there is no generation of smoke or abnormal sound.<br />
If check is not executed, a fire or an electric shock is caused.<br />
Before test run, install the front panel and cabinet.<br />
Check after reinstallation<br />
Check the following items after reinstallation.<br />
1) The earth wire is correctly connected.<br />
2) The power cord is not caught in the product.<br />
3) There is no inclination or unsteadiness and the installation is stable.<br />
If check is not executed, a fire, an electric shock or an injury is caused.<br />
CAUTION<br />
Put on gloves<br />
Cooling check<br />
Be sure to put on the gloves (∗) and a long sleeved shirt:<br />
otherwise an injury may be caused with the parts, etc.<br />
(∗) Heavy gloves such as work gloves<br />
When the power was turned on, start to work after the equipment has been<br />
sufficiently cooled.<br />
As temperature of the compressor pipes and others became high due to cooling/heating<br />
operation, a burn may be caused.<br />
