2. SAFETY SUMMARY
HITACHI cannot ancipate every possible circumstance
that might involve a potenal hazard.
!DANGER
• DO NOT perform installaon work and electrical wiring connec-
on by yourself. Contact your HITACHI distributor or dealer and
ask them for installaon work and electrical wiring by service
person.
!CAUTION
• DO NOT install the indoor unit, outdoor unit, 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 generaon, owing, staying or leaking of ammable
gas is detected.
✓Where the sea is near (in the salty environment).
✓An acid or alkaline environment.
• DO NOT install the indoor unit, outdoor unit, controller and cable
within approximately 3 meters from strong electro magnec
wave radiators such as medical equipment. In case that the con-
troller is installed in a place where there is electromagnec wave
radiaon, 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 lter.
• Use specied cables to connect between indoor unit and remote
control switch. Selecng incorrect cables may lead to re or
electrical shock.
NOTE
• The installer and system specialist shall comply with local regula-
ons or standards for the safety. The following standards may
be applicable, if local regulaons are not available. Internaonal

for the electrical wiring work and check, turn OFF the main power
supply before opening/closing the service cover of indoor unit.
If service cover is opened with main power supply le on, it may
result in an electrical shock.

3. BEFORE INSTALLATION
1. The pressure of the refrigerant R410A is 1.4 mes
higher than that of the refrigerant R22 or R407C. The
refrigerant R410A and its refrigerant oil are more sus-
cepble to impuries such as moisture, oxide lm and
grease. During installaon work, therefore, make sure
that any moisture, dust, dierent refrigerant or dier-
ent refrigerant oil will not enter the refrigerant cycle.
2. Use the specied tool exclusively for the refrigerant
R410A in order to prevent any dierent refrigerant or
refrigerant oil from entering the refrigerant cycle.
3. If you use the specied refrigerant pipe exclusively
for the refrigerant R410A, perform the aring work as
shown below.
4. Exisng outdoor and indoor units for R22 or R407C
can not be used.
5. For systems with several indoor units, branch pipes
shall be changed to Hitachi-specied model.
6. Special aenon is required with regard of the piping
thickness for R410A
7. Exisng pipes can be used without cleaning if the fol-
lowing condions are sased:
a. The renewal kit shall be installed. (mandatory)

b. Maximum piping length shall be 50 m (If the pipe
is longer than 50m, exisng pipes can be used if
cleaning is performed).
c. The capacity of the new unit must be equivalent
to the one previously installed.
d. Exisng pipes shall be free of corrosion, cracks,
scratches or deformaons.
e. Dirt inside the pipes shall not be noceable.
f. The specicaons of piping, are nuts, gaskets,
etc. shall be compliant.
g. Flare shall be reprocessed.
h. Piping airghtness and vacuuming shall be en-
sured in the same way as with new piping.
8. When exisng Air-Condioner is a product of another
manufacturer. Exisng pipes made by other manu-
facturer can also be used if the following condions
sased:
a. For systems with several indoor units, branch
pipes shall be changed to Hitachi-specied model.
b. Please perform a pipe cleaning.
!CAUTION
Recovering R22 and R407C is mandatory to remove an exisng air
condioner and piping. Do not vent into the atmosphere.

Apply a thin layer of oil to the cone opening for refrigera-
on systems. Line up the end of the ared pipe to face
the ng to which it is to be threaded.
Gently rest the female cone on the male cone and check
that the measurement is correct. Keep the connecon
lined up with one hand and gently thread on the are nut
with the other.
Tighten the connecon to the corresponding ghtening
torque indicated in the table.

5. INSTALLATION
5.1 Installaon Using the Exisng Refrigerant
Piping
DANGER
• Use non-ammable and non-toxic cleaning agent for cleaning
the piping. Flammable cleaning agent may cause an explosion
or a re.
• Open the window for venlaon during the installaon. If not,
it may result in an oxygen shortage.
• Make sure that cleaning agent does not contact re or reach a
high temperature, as toxic gas will generate.
NOTE
• Make sure to collect cleaning agent aer cleaning the piping. It
is strictly prohibited to release Fluorocarbons into the atmos-
phere without any reason.
• During heang operaon, the maximum pressure on the exisng
piping must be less than the allowable pressure (3.6MPa). When
using the exisng piping with a diameter of Ø19.05, therefore,
set No.4 pin of DSW2 on outdoor unit PCB to “ON” to keep the
maximum pressure on the piping less than 3.6MPa.
By using this Renewal Kit TRF-NP Series, the exisng
piping can be used for a new air condioner without
cleaning the piping under the following condions.
Condions for using the exisng refrigerant piping
1. The total length of the exisng refrigerant piping shall
be up to 50m.
2. The new UTOPIA Series air condioner to be installed
shall be for 12HP or less.
3. Make sure to check that there are no scratches and
dents on the surface of the exisng refrigerant pipe
nor smudges inside the pipe.
4. The are nut and the piping diameter shall be based
on JIS (Japanese Industrial Standards). The thickness
of copper pipe is indicated in the table below.
5. Perform the aring work of the exisng refrigerant
piping again before installaon.
6. Make sure to conduct an air-ght test and vacuuming
of the piping.
Copper pipe thickness (mm)
Diameter
(Ød) Thickness Material
6.35 0.8 O Material
9.52 0.8 O Material
12.7 0.8 O Material
15.88 1.0 O Material
19.05 1.0 O Material
22.2 1.2 O Material
25.4 1.0 1/2H Material
28.58 1.0 1/2H Material
NOTE
• The uorocarbons must be collected when removing the old air
condioner.
• If the total length of the exisng piping is over 50m, the renewal
kit cannot be used. However, if cleaning work of the exisng
refrigerant piping is carried out, the exisng refrigerant piping is
available without renewal kit.
For using the piping made by other companies
The exisng refrigerant piping of air condioner made
by other companies can be used for a new HITACHI air
condioner only if complying with the item “Condions
for Using the Exisng Refrigerant Piping” and the follow-
ing points.
1. Use the branch piping (for 410A) specied by
HITACHI. If using the branch piping made by other
companies, make sure to check the followings.
a. The allowable pressure shall be 3.6MPa or more.
b. Set No.4 pin of DSW2 on outdoor unit PCB to
“ON.” (This is not required if the allowable pres-
sure of the branch piping is 4.15MPa or more.)
c. Y-shaped branches shall be adopted for branch
pipes.
2. If the system for the exisng air condioner is Gas
Heat Pump System, clean the exisng refrigerant pip-
ing before installaon.
