INSTALLATION OF OPTIONAL REMOTE CONTROLLER
%
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;
§
where there is oil vapor and the oil is dispersed.
§
where the hot springs are near (in a sulfuric
environment).
§
where generation, flowing, staying or leaking of
flammable gas is detected.
§
where the sea is near (in the salty environment).
§
an acid or alkaline environment.
§
where children can touch.
§
where the air from the air conditioner is directly
discharged.
– DO NOT install the indoor unit, outdoor unit, controller
and cable within approximately 3 meters from strong
electromagnetic wave radiators such as medical
equipment.
– In case that the controller is installed in a place where
there is electromagnetic radiation, shield the controller
and cables by covering with the steel box and running
the cable through the metal conduit cable.
– In case that there is electric noise at the power source
for the Indoor Unit, provide a noise filter.
&
CAUTION:
– 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.

Location of Remote Controller
1. Select a suitable place for handling and determine the
installation place of the controller with the customer’s
acceptance.
2. Specially 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 children can't touch
- where the thermostat is not exposed directly to the
sun
- where the heat sources are 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 not directly
discharged
- In case of installing the wireless remote control
switch onto the wall, keep a distance of more than
30 cm from the power line.
?
NOTE:
For extension of the connection cable (2-core)
between the units in case of simultaneous operation of
multiple units, use the control cable (field-supplied) or
the extension cable (optional accessory).
When connecting wires, cut the remote control cable
at the middle, connect the wires by soldering and
insulate them.
For one remote controller, the maximum total length of
the cable (including the signal wire between units) is
30 m when using 0.3 mm² cable and 500 m when
using the cable thicker than 0.75 mm².
