D A N G E R
•
DO NOT pour water into the central station (hereafter called "controller"). This product is equipped with electrical parts. If water is
poured, it will cause a serious electrical shock.
•
Prior to the installation work, ensure that foundation is flat, level and sufficiently strong and then fix the unit securely. If the foundation
is not strong enough, it may lead to injuries caused by falling of the product, electrical shock or fire.
•
DO NOT install the unit in a place where generation, flow, accumulation or leakage of flammable gas is detected.
•
DO NOT perform installation work and electrical wiring connection by yourself. Contact your distributor or dealer of HITACHI and ask
them for installation work and electrical wiring by a trained service person.
•
Perform electrical work according to the Installation Manual and all relevant regulation and standards. If the instructions are not followed,
electrical shock and fire may occur due to insufficient capacity and inadequate performance.
•
Use the specified cables for connection between indoor unit and central station. Selecting incorrect cables may lead to fire or electrical
shock.
•
Turn OFF the main power supply entirely before opening or closing the service cover of the indoor unit, since the power terminal or
the power switch part may otherwise be still powered on and cause an electrical shock. Turn OFF the main power supply also when
performing wiring works.
•
When performing local wiring work, check whether the local wiring has been gnawed by animals like mice or small rodents. Gnawed
wiring could cause a fire.
