READ THESE INSTRUCTIONS CAREFULLY BEFORE
INSTALLATION. KEEP THIS MANUAL IN A HANDY
PLACE FOR FUTURE REFERENCE.

IMPROPER INSTALLATION OR ATTACHMENT OF
EQUIPMENT OR ACCESSORIES COULD RESULT IN
ELECTRIC SHOCK, SHORT-CIRCUIT, LEAKS, FIRE OR
OTHER DAMAGE TO THE EQUIPMENT. BE SURE ONLY
TO USE ACCESSORIES MADE BY DAIKIN WHICH ARE
SPECIFICALLY DESIGNED FOR USE WITH THE
EQUIPMENT AND HAVE THEM INSTALLED BY A
PROFESSIONAL.

DAIKIN EQUIPMENT IS DESIGNED FOR COMFORT
APPLICATIONS. FOR USE IN OTHER APPLICATIONS,
PLEASE CONTACT YOUR LOCAL DAIKIN DEALER.

IF UNSURE OF INSTALLATION PROCEDURES OR USE,
ALWAYS CONTACT YOUR DEALER FOR ADVICE AND
INFORMATION.

THIS AIR CONDITIONER COMES UNDER THE TERM
"APPLIANCES NOT ACCESSIBLE TO THE GENERAL
PUBLIC".

1. SAFETY CONSIDERATIONS

The precautions listed here are divided into the following two types.
Both cover very important topics, so be sure to follow them carefully.

WARNING

If the warning is not observed, it may cause serious casualties.

CAUTION

If the caution is not observed, it may cause injury or damage to the
equipment.

Warning

■ Ask your dealer or qualified personnel to carry out installation
work. Do not install the machine by yourself.
Improper installation may result in water leakage, electric shocks
or fire.

■ Perform installation work in accordance with this installation
manual.
Improper installation may lead to water leakage, electric shocks
or fire.

■ When a unit is installed in a small room, it is necessary to take
measures so that the leaked refrigerant amount does not exceed
the limit even if it leaks. As for the measures to prevent the leak
from not exceeding the limit, please consult with your distributor.
If the leaked amount exceeds the limit, it may cause an oxygen
deficiency accident.

■ Be sure to use only the specified accessories and parts for
installation work.
Failure to use the specified parts may result in water leakage,
electric shocks, fire, or the unit falling.

■ Install the air conditioner on a foundation that can withstand its
weight.
Insufficient strength may result in the fall of equipment and
causing injury.

■ Carry out the specified installation work in consideration of strong
winds, typhoons, or earthquakes.
Improper installation work may result in accidents due to fall of
equipment.

Installation manual

RXYSQ4~6PA7V1B + RXYSQ4~6PA7Y1B

VRVIII-S system air conditioner

4PW40730-1A

■ Make certain that all electrical work is carried out by qualified
personnel according to the local laws and regulations and this
installation manual, using a separate circuit.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or fire.

■ Make sure that all wiring is secure, using the specified wires and
ensuring that external forces do not act on the terminal
connections or wires.
Incomplete connection or fixing may cause a fire.

■ When wiring between the indoor and outdoor units, and wiring
the power supply, form the wires so that the frontside panel can
be securely fastened.
If the frontside panel is not in place, the terminals may overheat
and electric shocks or a fire may be caused.

■ If refrigerant gas leaks during installation work, ventilate the
area immediately.
To xic gas may be produced if refrigerant gas comes into contact
with fire.

■ After completing the installation work, check to make sure that
there is no leakage of refrigerant gas.
To xic gas may be produced if refrigerant gas leaks into the room
and comes into contact with a source of fire, such as a fan
heater, stove or cooker.

■ Before touching electric terminal parts, turn off power switch.

■ Where flammable gases may leak, where carbon fiber or

ignitable dust is suspended in the air or where volatile
flammables, such as thinner or gasoline, are handled.

Such gases may cause a fire.

■ Where the air contains high levels of salt such as that near
the ocean.

■ Where voltage fluctuates a lot, such as that in factories.

■ In vehicles or vessels.

■ Where acidic or alkaline vapour is present.

■ Do not allow a child to mount on the outdoor unit or avoid

■ Ground the air conditioner.
Grounding resistance should be according to national
regulations
Do not connect the earth wire to gas or water pipes,
lightning conductor or telephone earth wire.
Incomplete grounding may cause electric shocks.

■ Gas pipe.

Ignition or explosion may occur if the gas leaks.

■ Water pipe.

Hard vinyl tubes are not effective grounds.

■ Lightning conductor or telephone ground wire.

Electric potential may rise abnormally if struck by a lightning
bolt.

■ Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may cause electric
shocks or fire.

■ Install drain piping according to this installation manual to
ensure good drainage, and insulate the pipe to prevent
condensation.
Improper drain piping may cause water leakage, and make the
furniture get wet.

■ Install the indoor and outdoor units, power wire and connecting
wire at least 1 meter away from televisions or radios to prevent
image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not
be sufficient to eliminate the noise.)

■ Do not rinse the outdoor unit.
This may cause electric shocks or fire.

■ Do not install the air conditioner in places such as the following:

■ Where there is mist of mineral oil, oil spray or vapour for

example a kitchen.
Plastic parts may deteriorate, and cause them to fall out or

water to leak.

■ Where corrosive gas, such as sulfurous acid gas, is

produced.
Corrosion of copper pipes or soldered parts may cause the

refrigerant to leak.

■ Where there is machinery which emits electromagnetic

waves.
Electromagnetic waves may disturb the control system, and

cause malfunction of the equipment.

Refer to the Engineering Data Book for the complete list of
specifications.

4. SELECTING INSTALLATION SITE

This 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.

3. BEFORE INSTALLATION

Since design pressure is 4.0 MPa or 40 bar, pipes of larger
wall thickness may be required. Refer to paragraph

"7.1. Selection of piping material" on page 6.

3.1. Precautions for R410A

■ The refrigerant 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
Read "8. Precautions on refrigerant piping" on page 6 carefully
and follow these procedures correctly.

■ Since R410A is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state. (If the refrigerant
is in state of gas, its composition changes and the system will
not work properly).

■ The connected indoor units must be indoor units designed
exclusively for R410A.

3.2. Installation

■ For installation of the indoor unit(s), refer to the indoor unit
installation manual.

■ Never operate the air conditioner with the discharge pipe
thermistor (R2T), suction pipe thermistor (R3T) and pressure
sensors (S1NPH, S1NPL) removed. Such operation may burn
out the compressor.

■ Be sure to confirm the model name and the serial no. of the
outer (front) plates when attaching/detaching the plates to avoid
mistakes.

■ When closing the service panels, take care that the tightening
torque does not exceed 4.1 N•m.

■ Make sure to provide for adequate measures in order
to prevent that the outdoor unit be used as a shelter
by small animals.

■ Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean.

1 Select an installation site where the following conditions are

satisfied and that meets with your customer's approval.

- Places which are well-ventilated.

- Places where the unit does not bother next-door neighbours.

- Safe places which can withstand the unit's weight and
vibration and where the unit can be installed level.

- Places where there is no possibility of flammable gas or
product leak.

- Places where servicing space can be well ensured.

- Places where the indoor and outdoor units' piping and wiring
lengths come within the allowable ranges.

- Places where water leaking from the unit cannot cause
damage to the location (e.g. in case of a blocked drain pipe).

- Places where the rain can be avoided as much as possible.

2 When installing the unit in a place exposed to strong wind, pay

special attention to the following.
Strong winds of 5 m/sec or more blowing against the outdoor

unit's air outlet causes short circuit (suction of discharge air),
and this may have the following consequences:

- Deterioration of the operational capacity.

-Frequent frost acceleration in heating operation.

- Disruption of operation due to rise of high pressure.

- When a strong wind blows continuously on the face of the
unit, the fan can start rotating very fast until it breaks.

Refer to the figures for installation of this unit in a place where
the wind direction can be foreseen.

■ Tu rn the air outlet side toward the building's wall, fence or
screen.

3.3. Handling

As shown in the figure, bring the unit slowly by grabbing the left and
right grips.

Place your hands on the corner instead of holding the suction inlet in
the side of the casing, otherwise the casing could be deformed.

Ta ke care not to let hands or objects come in contact with
rear fins.

Make sure there is enough room to do the installation

■ Set the outlet side at a right angle to the direction of the wind.

7. REFRIGERANT PIPE SIZE AND ALLOWABLE

PIPE LENGTH

All field piping must be installed by a licensed refrigeration
technician and must comply with relevant local and
national regulations.

To persons in charge of piping work:

■ Be sure to open the stop valve after piping installing
and vacuuming is complete. (Running the system with
the valve closed may break the compressor.)

■ It is forbidden to discharge refrigerant into the
atmosphere. Collect the refrigerant in accordance
with the freon collection and destruction law.

■ Do not use flux when brazing the refrigerant piping.
For brazing, use phosphor copper brazing filler metal
(BCuP) which does not require a flux.
(If a chlorine flux is used, the piping will corrode, and if
the flux contains fluoride, it will cause the coolant oil to
deteriorate, adversely affecting the coolant piping
system.

7.1. Selection of piping material

■ Foreign materials inside pipes (including oils for fabrication)
must be ≤30 mg/10 m.

■ Construction material: phosphoric acid deoxidized seamless
copper for refrigerant.

■ Temper grade: use piping with temper grade in function of the
pipe diameter as listed in table below.

■ The pipe thickness of the refrigerant piping should comply with
relevant local and national regulations. The minimal pipe
thickness for R410A piping must be in accordance with the table
below.

Temper grade of piping

Pipe Ø

6.4 / 9.5 / 12.7 O 0.80

15.9 O 1

19.1 1/2H 1

O = Annealed
1/2H = Half hard

material

■ Make sure to use the particular branches of piping that have
been selected.

■ In case the required pipe sizes (inch sizes) are not available, it is
also allowed to use other diameters (mm sizes), taken the
following into account:

■ select the pipe size nearest to the required size.

■ use the suitable adapters for the change-over from inch to

mm pipes (field supply).

Minimal thickness t

(mm)

■ Always use the supplied copper gasket when connecting the
gas pipe supplied with the unit. See "9. Refrigerant piping" on

page 7.

8.1. Cautions for brazing

■ Be sure to carry out a nitrogen blow when brazing.
Brazing without carrying out nitrogen replacement or releasing
nitrogen into the piping will create large quantities of oxidized
film on the inside of the pipes, adversely affecting valves and
compressors in the refrigerating system and preventing normal
operation.

■ When brazing while inserting nitrogen into the piping, nitrogen
must be set to 0.02 MPa with a pressure-reducing valve (=just
enough so that it can be felt on the skin).

8. PRECAUTIONS ON REFRIGERANT PIPING

■ Do not allow anything other than the designated refrigerant to
get mixed into the freezing cycle, such as air, 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).

■ In order to prevent dirt, liquid or dust from entering the piping,
cure the piping with a pinch or taping.

8.2. Cautions for flare connection

■ See the following table for flare part machining dimensions.

■ When connecting the flare nuts, apply refrigerant ether or ester

oil to the inside and outside of the flares and turn them three or
four times at first.

■ When loosening a flare nut, always use two wrenches in
combination. When connecting the piping, always use a spanner
and torque wrench in combination to tighten the flare nut.
