Hitachi RAS-D10EX5 Manual

FOR SERVICE PERSONNEL ONLY
• Carefully read through the procedures of proper installation
before starting installation work.

SAFETY PRECAUTION
• Read the safety precautions carefully before operating the unit.
• The contents of this section are vital to ensure safety. Please pay special attention to the following sign.
WARNING ............. Incorrect methods of installation may cause death or serious injury.
CAUTION .............. Improper installation may result in serious consequence.
Make sure to connect earth line.
This sign in the figures indicates prohibition.
Be sure that the unit operates in proper condition after installation. Explain to customer the proper operation and maintenance of the unit
as described in the user's guide. Ask customers to keep this installation manual together with the instruction manual.
WARNING
• Please request your sales agent or qualified technician to install your unit. Water leakage, short circuit or fire may occur if you do the installation work
yourself.
• Please observe the installation stated in the installation manual during the process of installation. Improper installation may cause water leakage, electric
shock and fire.
• Make sure that the units are mounted at locations which are able to provide full support to the weight of the units. If not, the units may collapse and impose
danger.
• Observe the rules and regulations of the electrical installation and the methods described in the installation manual when dealing with the electrical work.
Use cables which are approved official in your country. Be sure to use the specified circuit. A short circuit and fire may occur due to the use of low quality
wire or improper work.
• Be sure to use the specified cables for connecting the indoor and outdoor units. Please ensure that the connections are tight after the conductors of the
wire are inserted into the terminals to prevent the external force is being applied to the connection section of the terminal base. Improper insertion and
loose contact may cause over-heating and fire.
• Please use the specified components for installation work. Otherwise, the unit may collapse or water leakage, electric shock, fire or stronger vibration
may occur.
• Be sure to use the specified piping set for R410A. Otherwise, this may result in broken copper pipes or faults.
• When installing or transferring an air conditioner to another location, make sure that air other than the specified refrigerant (R410A) does not enter the
refrigeration cycle. If other air should enter, the pressure level of the refrigeration cycle may increase abnormally which could result in a rupture and injury.
• Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes into contact with fire, a poisonous gas may occur.
• After completion of installation work, check to make sure that there is no refrigeration gas leakage. If the refrigerant gas leaks into the room, coming into
contact with fire in the fan-driven heater, space heater, etc., a poisonous gas may occur.
• Unauthorized modifications to the air conditioner may be dangerous. If a breakdown occurs please call a qualified air conditioner technician or electrician.
Improper repairs may result in water leakage, electric shock and fire, etc.
• Be sure to connect the earth line from the power supply wire to the outdoor unit and between the outdoor and indoor unit. Do not
connect the earth line to the gas tube, water pipe, lighting rod or the earth line of the telephone unit. Improper earthing may cause
electric shocks.
• When finishing the refrigerant collection (pumping down), stop the compressor and then remove the coolant pipe. If you remove the refrigerant pipe while
the compressor is operating and the service valve is released, air is sucked and a pressure in the freezing cycle system will build up steeply, causing an
explosion or injury.
• When installing the unit, be sure to install the refrigerant pipe before starting the compressor.
If the refrigerant pipe is not installed and the compressor is operated with the service valve released, air is sucked and the pressure level of the
refrigeration cycle may increase abnormally which could result in a rupture and injury.
CAUTION
• A circuit breaker must be installed in the house distribution box for the direct connected power supply cables to the outdoor unit. In case of other
installations a main switch with a contact gap or more than 3mm has to be installed. Without a circuit breaker, the danger of electric shock exists.
• Do not install the unit near a location where there is flammable gas. The outdoor unit may catch fire if flammable gas leaks
around it.
• Please ensure smooth flow of water when installing the drain hose. Improper installing may wet your furniture.
• An IEC approved power cord should be used. Power cord type: NYM.

1 Two Way Air Exchange Hose Installation
The two way air exchange function is included in this model. Please follow the "two way air exchange hose" installation
instructions when mounting.
Conditions when the two way air exchange should not be operated (Please install only with the customer's consent).
• The two way air exchange should not be operated under the following conditions:
(A) When the two way air exchange hose cannot be vented directly outside the room (mounting work specified for the embedded ducting).
(B) When there is a source of a questionable odor, smoke, or oily smoke in the vicinity of the opening of the two way air exchange hose, even if the
mounting work directly vents the two way air exchange hose outside the room.
• The fresh air in should not be operated (only exhaust can be operated) under the following conditions:
(C) When there is space to vent the two way air exchange hose between the internal and external walls, which leads outside the room, even if the
mounting work cannot directly vent the Two way air exchange hose outside the room (conventional construction methods).
• Please set the Two Way Air Exchange Selection Switch according to the mounting configuration (refer to "Setting the Two Way Air Exchange Selection
Switch on page 12).
In the case of (A) or (C) in the above, two way air exchange can be operated if the two way air exchange hose is vented outside the room through a hole
in the wall (refer to "End Treatment of Two Way Air Exchange Hose" on page 15).

THE CONNECTION OF REFRIGERATING PIPE DURING THE INSTALLATION OF INDOOR UNIT
• The refrigerating pipe should be adjusted to fit into the hole on the wall and then ready for further connection.
• The terminals of 2 connected pipes must be covered with insulator used for terminal connection. Then the pipes are wrapped with insulation pipe.
CAUTION
• Connect the connecting cord after removing low cover. (Refer to "CONNECTION OF POWER CORD" on page 10.)
• After adjustment, fit the connecting cord and pipes into the space available under the unit. Use holder to hold them tight.
• Holder can be attached at the either of 2 places. Please select the easier position.
