Notes:
1. Standard performance (*1) is based on the following operating conditions. Temperature is based
on the dew point.
2. The maximum allowable current (*2) is based on the following over-load condition.
Overload condition should not be continuous.
3. IP rating (*3) does not take the cable gland into consideration.
To connect power lines with the terminals in the power supply terminal box, a cable gland specified
in 12-3 should be prepared and installed by each customer. The cable gland should be applied to
specified IP code (*3) and its level should be confirmed at prototype test.
4. Shock & vibration test
This compressor was examined under the standard installation environment using Vibration Proof
Rubber, which is the Hitachi standard mounting assembly and was confirmed to meet the
standards “IEC61373 (1999), Category 1, Class B.”When you use a product other than the
specified rubber hardness product, it is necessary to confirm that the above standards are met.
Otherwise, there may be problems such as, in the worst case scenario, breakage of legs of the
compressor due to abnormal vibrations.
5. Purpose of Use
The compressor shall not be used for purposes other than vehicle air conditioning.
4．RELATED LAWS AND REGULATIONS
IEC60335-1(2010)/ EN60335-1(2012) and IEC60335-2-34(2012)/ EN60335-2-34(2013) shall
apply.
5．COMMON SPECIFICATIONS FOR COMPRESSORS
5.1 Appearance
Black coating shall be applied to the entire surface of the compressor, and there should be no
significant scratches, dents, peeled paint, and rust in appearance.
5.2 Marking
The nameplate that describes the following contents shall be attached in a visible position on
the surface of the compressor using a method that is difficult to peel off:
Compressor model, type of refrigerant, number of poles, number of phases, rated voltage,
rated frequencies, production month and year, rated output of motor, locked rotor current,
refrigerant oil enclosed capacity, compressor weight, production number, maximum allowable
pressure (design pressure), maximum/minimum allowable temperature, IP codes.
Refer to Clause 13 “Nameplate Marking Contents” for details.

5.3 Insulation Distance
IEC60335-2-34 shall apply.
5.4 Insulation Resistance
Insulation resistance should be measured between the charging part and non-charging metal
part using the 500V insulation resistance tester at room temperature and normal humidity,
and it should be 10MΩor higher.
5.5 Withstand Voltage
After the test in 5.4 is complete, apply AC voltage using the gradually ramp method between
the charging part and non-charging metal part (2E + 1000)V, (E: rated voltage). The
compressor shall withstand for one minute continuously.
5.6 Test Pressure
The compressor shall comply with IEC60335-1 and IEC60335-2-34.
5.7 Operating Noise and Vibration
There shall be no abnormal noise and vibration when the compressor is operated or starts
and stops within the usage conditions of the compressor.
5.8 Storage
* The compressor should be stored in a clean and dry place.
* The compressor is a horizontal type. It should be transported and stored in the horizontal
position.
* Do not store the compressor outdoors and in a place where water-drops from the
circumferences will pour onto it.
There may be the following harmful influence under conditions in which water-drops are
poured:
・Corrosion on the surface of the compressor (rust or blisters)
・Water entry into the terminal box.
* The compressor should be stored on a double stack at most based on the packing
specifications when shipping. Refer to Clause 14 “Packing Specifications” for details.
* The storage temperature should be within - 20 ℃to + 50 ℃.
* The oil in this compressor is synthetic oil, which has higher moisture absorbency than
conventional oil. Do not leave it exposed to the air for a long time, and it should be limited
within 3 to 5 minutes as a guide.
5.9 Moving and Transportation
* Falling, dragging and being impacted during work are prohibited. The compressor should
be handled carefully so as not to apply force locally to the convex part, such as the pipes, the
power supply terminal box (including terminal plugs), and the legs. Also the compressor
should not be moved when holding the power supply terminal box.
* In the case of horizontal type compressors, they should be handled in the horizontal position
at the time of storage and transport.
5.10Change and Addition
When there is a need to change or add to the items prescribed in these specifications, both
parties shall communicate the contents and the reasons in writing promptly and obtain
approval.
5.11 Discontinued Production
For models that are already delivered, production may be discontinued according to our
company’s circumstances.

4
5.12Occurrence of Problems
If problems occur after delivery, both parties shall raise them promptly and solve them in good
faith.
5.13Warranty
Only when production defects are found within two years after production of the compressor,
and our company recognizes the production defects, will a replacement product be supplied.
Any defects occurred by other causes are not covered by the warranty: ex) when scroll
compressors are operated under conditions that deviate from the delivery specifications and
the Engineering Manual, or in an environment where moisture, dust, liquid return and
vibrations are observed in the refrigerant cycle.
When a different warranty condition is agreed in a sales contract or other documentation, that
shall take precedence.
5.14 Compressor Specifications
These specifications shall become effective on the date of issuance by our company. A
customer shall put a seal of receipt or sign in the specified location, and return them by the
time the order is accepted by our company. If they are not returned by the time the order is
accepted, the contents of these specifications shall be deemed approved.
