vapour (e.g. a kitchen).
Plastic parts may deteriorate and cause parts to fall off or
water to leak.
2. Where corrosive gas, such as sulphurous acid gas, is pro-
duced.
Corrosion of copper pipes or brazed parts may occur and
cause refrigerant leakage.
3. Where there is a machine that generates electromagnetic
wave and where voltage fluctuation often occurs such as a factory.
Control system may malfunction and as a result the unit may
not properly operate.
4. Where flammable gas may leak, where carbon fibre or ignit-
able dust is suspending in the air, or where volatile flammables
such as paint thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.
• The air conditioner is not intended for use in a potentially explosive atmosphere.
1-2 Special notice of product
[CLASSIFICATION]
This air conditioner comes under the term “appliances not accessible
to the general public”.
[EMC CHARACTERISTICS]
VRVIII System is a class A product. In a domestic environment this
product may cause radio interference in which case the user may be
required to take adequate measures.
[REFRIGERANT]
VRVIII System use R410A refrigerant.
• The refrigerant R410A requires that strict precautions be
observed for keeping the system clean, dry and tightly sealed.
Read the chapter “REFRIGERANT PIPING” carefully and follow
these procedures correctly.
A.Clean and dry
Strict measures must be taken to keep impurities (including
fluid, dirt and dust) out of the system.
B.Tightly sealed
R410A contains no chlorine, does not destroy the ozone layer
and so does not reduce the earth’s protection against harmful
ultraviolet radiation. R410A will contribute only slightly to the
greenhouse effect if released into the atmosphere. Therefore,
sealing tightness is particularly important in installation. Carefully read the chapter “REFRIGERANT PIPING” and strictly
observe the correct procedures.
• As the design pressure for local connection piping (suction·HP/LP
gas pipe, gas pipe, and liquid pipe) is at least 3.3 MPa, it is possible to use existing piping (design pressure of at least 3.3 MPa,)
but refer to "6. REFRIGERANT PIPING" and check that existing
piping (including branch piping) is compatible with this unit in
terms of materials and thickness and that it does not appear to be
corroded.
Air tight test (3.3 MPa 24/h) to check the strength of existing piping
and that it has no gas leaks.
If it is not possible to perform a pressure test, replace existing piping with piping rated at least 3.3 MPa.
• Check that there has not been compressor malfunction, gas supply exhaustion, or similar issues that could be attributable to pipe
problems in the past. If there have been any such problems,
check that appropriate repairs were made, and if not, implement
such repairs.
• Existing power supply and transmission wiring is also designed to
be used with existing wiring, but check that specifications match
and that parts (especially terminals) do not appear to have aged,
and implement appropriate procedures (e.g. replacement).
• Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state. (If the system is charged
with refrigerant in its gaseous state, due to composition change,
the system will not function normally).
• The indoor unit is designed for R410A use. See the catalogue for
indoor unit models that can be connected. (Normal operation is
not possible when connecting units that are originally designed for
other refrigerants.)
• The Heat Recovery Series (RQCEQ) cannot be connected to
older BS units (BSVQ-M Type).
Total maximum refrigerant charge limits.
The total maximum refrigerant charge of a VRVIII system must be
below 100kg, this to be in accordance with CE requirement
(EN60335-2-40 standard).
This means that in case the total maximum refrigerant charge of the
system (factory and additional charge) is equal to or more than 100kg
you must divide your multiple outdoor system into smaller independent systems, each containing less than 100kg refrigerant charge.
For factory charge, refer to the unit name plate.

[DESIGN PRESSURE]
• As the design pressure for local connection piping (suction·HP/LP
gas pipe, gas pipe, and liquid pipe) is at least 3.3 MPa, it is possible to use existing piping (design pressure of at least 3.3 MPa) but
refer to "6. REFRIGERANT PIPING" and check that existing piping (including branch piping) is compatible with this unit in terms
of materials and thickness and that it does not appear to be corroded.
Air tight test (3.3 MPa 24/h) to check the strength of existing piping
and that it has no gas leaks.
If it is not possible to perform a pressure test, place existing piping
with piping rated at least 3.3 MPa.
• Check that there has been no compressor malfunction, gas supply exhaustion, or similar issues that could be attributable to pipe
problems in the past. If there have been any such problems,
check that appropriate repairs were made, and if not, implement
such repairs.
1-3 Disposal requirements
Dismantling of the unit, treatment of the refrigerant, of oil and of other
parts must be done in accordance with relevant local and national
legislation.
2. INTRODUCTION

3. SELECTION OF LOCATION
Select a location for installation that meets the following conditions.
Get the customer’s permission.
1.
There is no danger of fire due to leakage of flammable gas.
2.
Select the location of the unit in such a way that neither the discharged air nor the sound generated by the unit disturb anyone.
3.
The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation.
4.
The piping length between the outdoor unit and the indoor unit
may not exceed the allowable piping length. (Refer to
“6. REFRIGERANT PIPING”)
5.
Locations where the unit’s suction vent and outlet vent do not
directly face the wind.
Wind blowing directly into the suction or outlet vents will interfere
with the unit’s operation.
If necessary, install some kind of obstruction to block the wind.
6.
The space around the unit is adequate for servicing and the minimum space for air inlet and air outlet is available.
(See the “Installation Space Examples” for the minimum space
requirements.)
Installation Space Examples.
• The installation space requirement shown in figure 3 is a reference for cooling operation when the outdoor temperature is 35°C.
If the design outdoor temperature exceeds 35°C or the heat load
exceeds maximum capacity in all the outdoor unit, take an even
large space on the intake shown in figure 3.
• During installation, install the units using the most appropriate of
the patterns shown in figure 3 for the location in question, taking
into consideration human traffic and wind.
• If the number of units installed is more than that is shown in the
pattern in figure 3, install the units so there are no short circuits.
• As regards space in front of the unit, consider the space needed
for the local refrigerant piping when installing the units.
• If the work conditions in figure 3 do not apply, contact your dealer
or Daikin directly.
(Refer to figure 3)
1. Front side
2. No limit to wall height
3. Service space of front side
4. Service space of suction side
For Patterns 1 and 2 in figure 3:
• Wall height for the front side should be no higher than 1500
mm.
• Wall height for the suction side should be no higher than 500
mm.
• Wall height for the sides – no limit.
English 4
• If the height is exceeded the above, calculate h1 and h2 shown
in the figure below, and add h1/2 to the service space of front
side and h2/2 to the service space of suction side.

1500
Front side
h1 = A (Actual height) – 1500
h2 = B (Actual height) – 500
Note
1.
An inverter air conditioner may cause electronic noise generated from AM broadcasting. Examine where to install the main
air conditioner and electric wires, keeping proper distances
away from stereo equipment, personal computers, etc.
Particularly for locations with weak reception, ensure there is
a distance of at least 3 meters for indoor remote controllers,
place power wiring and transmission wiring in conduits, and
ground the conduits.

2.
When installing in a locations where there is heavy snowfall,
implement the following snow measures.
• Ensure the base is high enough that intakes are not clogged
by snow.
• Remove the rear intake grille to prevent snow from accumulating on the fins.
3.
If condensate may drip downstairs (or walkway) depending on
the floor condition, take a measure such as the installation of
central drain pan kit (sold separately).
4.
The refrigerant R410A itself is nontoxic, nonflammable 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.
See “14. CAUTION FOR REFRIGERANT LEAKS” for details.

4. INSPECTING AND HANDLING THE UNIT
• At delivery, the package should be checked and any damage
should be reported immediately to the carrier claims agent.
• When handling the unit, take into account the following:
1.
Fragile, handle the unit with care.
Keep the unit upright in order to avoid compressor damage.
2.
Decide on the transportation route.
3.
If a forklift is to be used, pass the forklift arms through the large
openings on the bottom of the unit. (Refer to figure 5)
4.
If hanging the unit, use a cloth sling to prevent damaging the unit.
Keeping the following points in mind, hang the unit following the
procedure shown in figure 6.
• Use a sling sufficiently strong to hold the mass of the unit.
• Use 2 belts of at least 8m long.
• Place extra cloth or boards in the locations where the casing
comes in contact with the sling to prevent damage.
• Hoist the unit making sure it is being lifted at its center of gravity.
5.
After installation, remove the transportation clasp attached to the
large openings. (Refer to figure 6)
6.
If carrying baggage the unit, hold hand top rear handle product
and basic front lower leg product, carry as shown in figure 7.
• Because the equipment break, the product do not slant than
60 degree.
• Regularly wear glove to work.
• Obey local law about work method, and work more than 4 per-
sons.

Note
Apply a filler cloth on a fork to prevent coating of the bottom frame
from coming off and rust from occurring when bringing in the unit with
anti-corrosion treatment type using a forklift.
5. PLACING THE UNIT
• Make sure the unit is installed level on a sufficiently strong base to
prevent vibration and noise. (Refer to figure 8)
• The base should be bigger around than the width of the unit’s legs
(66 mm), and should support the unit. (Refer to figure 9)
If protective rubber is to be attached, attach it to the whole face of
the base.
• The height of the base should be at least 150mm from the floor.
• Secure the unit to its base using foundation bolts. (Use four commercially available M12-type foundation bolts, nuts, and washers.)
• The foundation bolts should be inserted 20 mm.
(Refer to figure 8)

Note
• There are restrictions on the refrigerant pipe connecting order
between outdoor unit in the case of the multi system.
See the Note in “2-1 Combination” for detail.
• When installing on a roof, make sure the roof floor is strong
enough and be sure to water-proof all work.
• Make sure the area around the machine drains properly by setting
up drainage grooves around the foundation.
Drain water is sometimes discharged from the outdoor unit when
it is running.
• For anti-corrosion type use nuts with resin washers. If the paint on
nut connections comes off, the anti-corrosion effect may
decrease.

6. REFRIGERANT PIPING
Note
• All field piping must be installed by a licensed refrigeration technician and must comply with relevant local and national regulations.
• After piping work is complete, do not under any circumstances
open the shutoff valve until “7. FIELD WIRING” and “10. CHECKING OF DEVICE AND INSTALLATION CONDITIONS” are complete.
•
Do not use flux when brazing the refrigerant piping. Use the phosphor copper brazing filler metal
710/795: ISO 3677)
(Flux has extremely harmful influence on refrigerant piping sys-
tems. For instance, if chlorine based flux is used, it will cause
pipe corrosion or, in particular, if the flux contains fluorine, it will
damage the refrigerant oil.)
which does not require flux.
6-1 Selection of piping material and Refrigerant
branching kit
• Use only pipes which are clean inside and outside and do not
accumulate harmful sulfur, oxidants, dirt, cutting oils, moisture, or
other contamination. (Foreign materials inside pipes including oils
for fabrication must be 30mg/10m or less.)
