the terminals of the main terminal, main circuit capacitors
or electrical parts and, before touching, be sure that those
voltages are 50 V DC or less.

When service panels are removed, live parts can easily be
touched by accident. Never leave the unit unattended
during installation or servicing when the service panel is
removed.

DANGER: DO NOT TOUCH PIPING AND INTERNAL
PAR TS

Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.

Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if you
must touch them, be sure to wear protective gloves.

Also, at least, following information shall be provided at an accessible
place of the system:

 Instructions for shutting down the system in case of an

The equipment described in this manual may cause
electronic noise generated from radio-frequency energy.
The equipment complies to specifications that are
designed to provide reasonable protection against such
interference. However, there is no guarantee that
interference will not occur in a particular installation.

It is therefore recommended to install the equipment and
electric wires keeping proper distances away from stereo
equipment, personal computers, etc.

1 Personal computer or radio
2 Fuse
3 Earth leakage protector
4 User interface
5 Indoor unit
6 Outdoor unit

In places with weak reception, keep distances of 3 m or more to
avoid electromagnetic disturbance of other equipment and use
conduit tubes for power and transmission lines.

 The refrigerant R410A itself is nontoxic, non-flammable and is

safe. If the refrigerant should leak however, its concentration
may exceed the allowable limit depending on room size. Due to
this, it could be necessary to take measures against leakage.
Refer to "18. Caution for refrigerant leaks" on page 48.

 Do not install in the following locations:

- Locations where sulphurous acids and other corrosive gases
may be present in the atmosphere. Copper piping and
soldered joints may corrode, causing refrigerant to leak.

- Locations where a mineral oil mist, spray or vapour may be
present in the atmosphere. Plastic parts may deteriorate and
fall off or cause water leakage.

- Locations where equipment that produces electromagnetic
waves is found. The electromagnetic waves may cause the
control system to malfunction, preventing normal operation.

- Locations where flammable gases may leak, where thinner,
gasoline and other volatile substances are handled, or where
carbon dust and other incendiary substances are found in the
atmosphere. Leaked gas may accumulate around the unit,
causing an explosion.

 When installing, take strong winds, typhoons or earthquakes into

account, improper installation may result in the unit turning over.

6.3. Selecting a location in cold climates

NOTICE

When operating the unit in a low outdoor ambient
temperature, be sure to follow the instructions described
below.

To prevent exposure to wind and snow, install a baffle plate on the air
side of the outdoor unit:

1 Baffle plate

In heavy snowfall areas it is very important to select an installation
site where the snow will not affect the unit. If lateral snowfall is
possible, make sure that the heat exchanger coil is not affected by
the snow (if necessary construct a lateral canopy).

1 Construct a large canopy.
2 Construct a pedestal.

Install the unit high enough from the ground to prevent
burying in snow.

6.2. Weather related precautions

 Select a place where the rain can be avoided as much as

possible.

 Be sure that the air inlet of the unit is not positioned towards the

main wind direction. Frontal wind will disturb the operation of the
unit. If necessary, use a screen to block the wind.

 Ensure that water cannot cause any damage to the location by

adding water drains to the foundation and prevent water traps in
the construction.

 Do not install the unit in areas where the air contains high levels

of salt such as that near the ocean.

environment, use a nut with
plastic washer (1) to protect the
nut tightening part from rust.

9. Refrigerant pipe size and allowable pipe length

9.1. General information

NOTICE

The refrigerant R410A requires strict cautions for keeping
the system clean, dry and tight.

 Clean and dry: foreign materials (including mineral

oils or moisture) should be prevented from getting
mixed into the system.

 Tight: R410A does not contain any chlorine, does not

destroy the ozone layer, and does not reduce earth's
protection against harmful ultraviolet radiation. R410A
can contribute slightly to the greenhouse effect if it is
released. Therefore we should take special attention
to check the tightness of the installation.

9.2. Selection of piping material

NOTICE

Piping and other pressure containing parts shall comply
with the applicable legislation and shall be suitable for
refrigerant. Use phosphoric acid deoxidised seamless
copper for refrigerant.

NOTICE

Installation shall be done by a licensed installer, the choice
of materials and installation shall conform completely with
the applicable national and international codes.

In Europe, EN 378 is the applicable standard that shall be
used.

8.5. Method for removing transportation stay (only for

R(X/Y)(Y/M)Q14~20)

The yellow transportation stay installed over the compressor leg for
protecting the unit during transport must be removed. Proceed as
shown in the figure and procedure below.

unit. If the piping diameter of the sized up piping exceeds the
diameter of the piping before the first branch kit, than the latter also
requires a liquid piping and gas piping size up.

NOTICE

There are restrictions on the refrigerant pipe connection
order between outdoor units during installation in case of a
multiple outdoor unit system. Install according to following
restrictions. The capacities of outdoor units A, B and C
must fulfill the following restriction conditions: A≥B≥C.

 To avoid the risk of oil retention to the outmost outdoor unit,

always connect the stop valve and the piping between outdoor
units as shown in the 4 correct possibilities of the figure below.

Prohibited patterns: change to pattern 1 or 2.

9.6. Multi system piping installation

 Front connection

Remove the front plate knock out holes to connect (see figure
below).

 Bottom connection

Remove the knock out holes on the bottom frame and route the
piping under the bottom frame (see figure below).

9.6.1. Precautions when connecting piping between outdoor
units (multiple outdoor unit system)

 To connect the piping between outdoor units, an optional multi

connection piping kit BHFQ22P1007/1517 is always required.
When installing the piping, follow the instructions in the
installation manual that comes with the kit.

 Only proceed with piping work after considering the limitations

on installing listed here and in the chapter "10.2. Connecting the

refrigerant piping" on page 17 always referring to the installation

manual delivered with the kit.

9.6.2. Possible installation patterns and configurations

 The piping between the outdoor units must be routed level or

slightly upward to avoid the risk of oil retention into the piping.

 Do not allow anything other than the designated refrigerant to

get mixed into the refrigerant cycle, such as air, nitrogen, etc. If
any refrigerant gas leaks while working on the unit, ventilate the
room thoroughly right away.

 Use R410A only when adding refrigerant
 Installation tools:

Make sure to use installation tools (gauge manifold, charge
hose, etc.) that are exclusively used for R410A installations to
withstand the pressure and to prevent foreign materials (e.g.,
mineral oils and moisture) from mixing into the system.

 Vacuum pump:

- Use a 2-stage vacuum pump with a non-return valve.

- Make sure the pump oil does not flow oppositely into the

system while the pump is not working.

- Use a vacuum pump which can evacuate to –100.7 kPa

(5 Torr, –755 mm Hg).

Protection against contamination when installing pipes

Take measures to prevent foreign materials like moisture and
contamination from mixing into the system.

Installation period Protection method

More than a month Pinch the pipe

Less than a month

Regardless of the period

Pinch or tape the pipe

Do not use anti-oxidants when brazing the pipe joints. Residue can
clog pipes and break equipment:

 Do not use flux when brazing copper-to-copper refrigerant

piping. Use phosphor copper brazing filler alloy (BCuP) which
does not require flux.

 Flux has an extremely harmful influence on refrigerant piping

systems. For instance, if chlorine based flux is used, it will cause
pipe corrosion or, in particular, if the flux contains fluorine, it will
deteriorate the refrigerant oil.

10.2. Connecting the refrigerant piping

NOTICE

Installation shall be done by an installer, the choice of
materials and installation shall comply with the applicable
legislation. In Europe, EN 378 is the applicable standard
that shall be used.

Ensure that the field piping and connections are not
subjected to stress.

10.2.1. Decide front or side (bottom) connection

Installation of refrigerant piping is possible as front connection or side
connection (when taken out from the bottom) as shown in the figure
below.

Block all gaps in the holes for passing out piping and wiring using
sealing material (field supply) (the capacity of the unit will drop and
small animals may enter the machine).

Example: passing piping out through the front.

 Use clean pipes only.
 Hold the pipe end downwards when removing burrs.
 Cover the pipe end when inserting it through a wall so that no

dust or dirt enters the pipe.

NOTICE

After all the piping has been connected, make sure there is
no gas leak. Use nitrogen to perform a gas leak detection.

10.1. Caution for brazing

 Make sure to blow through with nitrogen when brazing. Blowing

through with nitrogen prevents the creation of large quantities of
oxidized film on the inside of the piping. An oxidized film
adversely affects valves and compressors in the refrigerating
system and prevents proper operation.

 The nitrogen pressure should be set to 0.02 MPa (i.e., just

enough so it can be felt on the skin) with a pressure-reducing
valve.

12 345

 For side connections, the knockout hole on the bottom plate

should be removed:

3

NOTICE

Precautions when knocking out knockout holes:

 Be sure to avoid damaging the casing.
 After knocking out the knockout holes, we recommend

you remove the burrs and paint the edges and areas
around the edges using repair paint to prevent rusting.

 When passing electrical wiring through the knockout

holes, wrap the wiring with protective tape to prevent
damage as shown above.

10.2.2. Remove the pinched pipes

WARNING

Any gas or oil remaining inside the stop valve may blow off
the pinched piping.

Failure to observe the instructions in procedure below
properly may result in property damage or personal injury,
which may be serious depending on the circumstances.
