Installation Of Remote Control Switch; Location Of Remote Controller - Hitachi PC-2H2 Installation Manual

1. INSTALLATION OF REMOTE CONTROL SWITCH <PC-2H2>
DANGER:
§ DO NOT pour water into the remote controller (hereafter
called "controller"). These products are equipped with
electrical parts. If poured, it will cause a serious electrical
shock.
§ DO NOT operate switches by wet hand. It may cause an
electrical shock.
§ In case that the protective devices often function or the
operation switches do not function well, turn OFF the main
power supply and contact your distributor or dealer of
HITACHI.
§ In case that other abnormalities are found, stop the system,
turn OFF the main power supply and contact your distributor
or dealer of HITACHI.
WARNING:
§ DO NOT perform installation work and electrical wiring
connection by yourself.
§ In case that a service work such as repair, maintenance, etc.
is required, contact your distributor or dealer of HITACHI.
§ DO NOT modify the electrical wiring. It may cause serious
accidents.
CAUTION:
§ DO NOT install the controller and cable at such places as;
(1) where there is oil vapor and the oil is dispersed.
(2) where the hot springs are near (in a sulfuric
environment).
(3) where generation, flowing, staying or leaking of
flammable gas is detected.
(4) where the sea is near (in the salty environment).
(5) an acid or alkaline environment.
§ DO NOT install the indoor unit, outdoor unit, controller and
cable within approximately 3 meters from strong
electromagnetic wave radiators such as medical equipment.
§ DO NOT use the multi-core wire for electrical wiring.
If used, some signals of one system transfer to the other
system, the signals interfere each other and it cause the
malfunction.
§ DO NOT use thin shield wire such as CPEVS. Such wires
with big electrostatic capacity make the transmission signal
dull end the transmission error may occurs in case of long
distance wiring.
§ DO NOT run any cable for transmission and signal along the
power line (220-240V, 380-415V).
§ DO NOT run any cable for transmission and signal along
other cables for transmission and signal.
If the cables are required to be run along, keep a distance
more than 30 cm between each cables, or insert the cables
for each transmission system into the metal conduit tube and
ground one end of the conduit tube.
INSTALLATION OF REMOTE CONTROL SWITCH <PC-2H2>
n Location of Remote Controller
1. Select a suitable place for handling and determine the
installation place of the controller with the customer's
acceptance.
Do not install the controller at such places as;
§ where children can touch
§ where the air from the air conditioner is directly
discharged
§ where there is oil vapor and the oil is dispersed
§ where the humidity is high.
Especially in case that a remote control thermostat is used,
select the installation place in consideration with the
following points;
§ where the average room temperature can be detected
§ where the thermostat is not exposed directly to the sun
§ where the heat sources is not near around
§ where the thermostat is not affected with the outdoor air
by opening and closing doors
§ where the air from the air conditioner is directly
discharged
2. Pay attention to the following points in case that the
controller is installed in a place where there is medical
equipment radiating electromagnetic waves.
§ DO NOT install the controller in a place where
electromagnetic waves are radiated directly toward the
remote control cable and the controller.
§ Keep a distance more than 3 meters away from the
equipment radiating electromagnetic waves.
§ Keep a distance more than 3 meters away from the
receiver such as radio. It may cause noises.
§ Shield the controller and cables by covering with the steel
box and running the cable through the metal conduit tube.
§ In case that there is electric noise at the power source for
the indoor unit, provide a noise filter.
§ In case of installing the wireless remote control switch
onto the wall, keep a distance more than 30 cm from the
power line.
