REFRIGERANT PIPING WORK

ALL REFRIGERANT PIPING WORK MUST ONLY BE CARRIED OUT BY A QUALIFIED PERSON

** For refrigerant piping of outdoor units, see the installation manual attached to the outdoor unit. **

Fully insulate the liquid and gas piping separately. Do not leave any gaps otherwise a water leak may occur.

(Seal any joints with glue or duct tape)

When operating in the heating mode, the temperature of the gas piping can reach up to approximately 120o C,

so use insulation which has a suitable temperature rating.

Also, in cases where the temperature and humidity surrounding the refrigerant piping can exceed 30o C or RH

80%, reinforce or use thicker pipe insulation (20 mm or thicker). Otherwise condensation may form on the

surface of the insulating material.

** Be sure to check the type of refrigerant to be used before doing any work. Using an incorrect refrigerant

will prevent normal operation of the unit. ** In case of FDYQ50-60DV1, FDYQ(N)71F & FDYQ(N) 100-160K

model(s) = R410a

CAUTION

l Avoid introduction of air or other contaminents into the refrigerant piping. If any air, moisture or other contaminent

remains in the refrigerant piping after the completion of installation the system will malfunction.

l Carry out sufficient ventilation if the refrigerant gas leaks during installation work.

l Use only R410a rated copper seamless tube manufactured to AS/NZS1571.

l Be sure to use both a spanner and torque wrench together, as shown in the diagram, when connecting or

disconnecting pipes to/from the unit. (Fig. 7)

l Use only a flaring block suitable for R410a tube. Refer to Table 2 for the specifications of the flare work.

l When connecting the flare nut, coat the flare both inside and outside with ether oil and initially tighten

by hand 3 or 4 turns before tightening firmly. (Fig. 8)

l Use the flare nuts included with the indoor unit.

l Refer to Table 2 to determine the proper tightening torque.

CAUTION

l Over tightening the flare nuts may cause the flare nuts or copper tube to fail and allow the refrigerant to leak.

l Caution to be taken when brazing refrigerant piping. (Where applicable)

Do not use flux when brazing refrigerant piping. Use the phosphor copper brazing filler metal (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, particularly if the flux contains fluorine, it will

damage the refrigerant oil.)

During any brazing of the refrigerant piping, you must continually blow dry nitrogen gas through the piping to

expel air from the piping. (Fig. 9) If you braze the piping without doing so a large amount of oxide film

develops inside the piping and could cause system failure.

Ensure that you use a pressure reducing valve on the dry nitrogen bottle to prevent pinholes caused by

excessively high pressure. (Set the pressure of nitrogen gas to about 0.2 kg / cm2 [19.6 kPa])

DRAIN PIPING WORKWARNING Install the drain pipe as shown below and take measures against condensation, improperly

installed piping may result in water leaks and eventually wet furniture and belongings.

(1) Installing

l Route the pipes so as to ensure that drainage can occur with no problems. (Fig. 10)

l Employ piping with either the same diameter or with the diameter larger

(excluding the raised section) than that of the connecting pipe (PVC

pipe, nominal diameter 25 mm, outside diameter 32 mm).

l Keep the drain pipe short and sloping downward at a gradient of

at least 1/100 to prevent air pockets from forming.

l To prevent the drain pipe from sagging, secure the pipe every

1 to 1.5 m.

l Use the provided drain hose 2 and clamp 1 . (Fig. 11)

Tighten the clamp firmly.

l Insulate the metal clamp with a field supplied sealing pad. (Fig. 11)

l Insulate the drain hose inside the building.

l As a safety measure, please use a safety drain tray (field supplied) and drain separately.

l Insulate drain pipe using piping thermal insulation to prevent condensate dripping during humid conditions.

Note

l To ensure no excessive pressure is applied to the included drain hose 2 , do not bend or twist when

installing. (This may cause leakage.)

WRONG CORRECT

Fig. 10

Not recommended but in case of an emergency

You must use a torque wrench but if you are obliged to install the unit without a torque wrench, you may follow

the installation method mentioned below.

As you keep on tightening the flare nut with a spanner there is a point where the tightening torque suddenly

increases. From that position, further tighten the flare nut using the angle shown below in Table 3:

After the work is finished, make sure to check that there is no gas leak.

PRECAUTIONS

Precaution for wiring on site

When connecting the indoor unit to a single phase of a 3 phase power supply, give consideration to the other

electrical equipment connected to the main breaker and select the phase (L1, L2, L3) so that the current (or

voltage) unbalance does not occur.

If current unbalance occurs, the phase current of the compressor may become unbalanced and there is a risk of

protective device actuating or compressor breakdown.

l Do not clamp remote controller cords together with wires connecting the units together. Doing so may cause

malfunction.

l Remote controller cords and wires connecting the units should be located at least 50 mm from other electric

wires. Not following this guideline may result in malfunction due to electrical noise.

Observe the notes mentioned below when wiring to the power supply terminal block. Precautions to be taken for

power supply wiring.

(Use a round crimp-style terminal for connection to the power supply terminal block. (Fig. 15) In case it cannot be

used due to unavoidable reasons, be sure to observe the following instructions.)

l Do not connect wires of different gauge to the same power supply terminal. (Fig. 16)

(Looseness in the connection may cause overheating.)

l When connecting wires of the same gauge, connect them according to the figure below.

l Make certain that prescribed wires are used, carry out complete connections, and secure the wires so that

outside forces are not applied to the terminals.

Fig. 15

Fig. 16

CAUTION

l After connecting the wires, be sure that no pressure is applied to the wire connections by using cable ties (field

supplied) and securing them to the anchor points. Also, when wiring, make sure the cover of the terminal box fits

snugly by arranging the wires neatly and attaching the terminal box cover firmly. When attaching the terminal

box cover make sure no wires get caught under the edges. Ensure that all the cables pass under the offset

section of the electrical box cover.

l Make sure the remote control cord, the wiring between the units, and other electrical wiring do not pass through

the same locations outside the unit, separating them by at least 50 mm, otherwise electrical noise (external

static) could cause incorrect operation of the unit or damage.

WIRING EXAMPLE for BRC1D619 only

(For the wiring of outdoor units, refer to the installation manual attached to the outdoor unit.)

Confirm the system type.

l Single phase pair type: 1 remote controller controls 1 indoor unit (standard system). (Fig. 17)

SETTING FAN AUTOMATIC ADJUSTMENT (FDYQ50-60DV1 Only)During commissioning stage use this mode to automatically adjust the fan RPM to achieve within +/- 10% of the rated

“High fan” speed airflow (HH). The High fan speed airflow can be adjusted to the rated airflow when the duct

External Static Pressure (ESP) is within the range of 40 – 180 Pa.

Note: Setting Fan Automatic Adjustment for multi zone systems.

Prior to the setting of Fan Automatic Adjustment, the zone that has the highest heat load should be nominated. For

example if the day zone is the nominated area, this area must be activated and the night zone must be deactivated

before commencing the Fan Automatic Adjustment mode.

HOW TO SET FAN AUTOMATIC ADJUSTMENT1) Set the controller to “Fan” mode.

2) Ensure the unit is switched “Off” by the controller “On-Off” button.

3) Hold down the “Test” button until “01” or “10” appears.

4) By pressing the temperature up arrow button scroll until mode number “21” appears.

5) By pressing the timer up arrow button scroll until the first code number setting “7” appears.

6) By pressing the timer down arrow button scroll until the second code setting “03” appears.

7) Press the confirmation button once & then the test button once. 88 will appear for a short time before returning to

normal operation.

8) Press the “On-Off” button to commence the Fan Automatic Adjustment setting. The operation lamp will illuminate &

the indoor fan will operate for a period of 1-8 minutes. To signal the completion of the adjustment, the indoor fan

will stop & the operation lamp will extinguish.

9) To confirm Fan Automatic Adjustment was successfully completed, repeat steps 3-5. Mode “21-7-02” should

appear. (If the indoor fan does not stop or 02 did not appear when Field Set Mode 21 is selected it means the Fan

Automatic Adjustment must be set again).

10) Press the test button once to return to normal operation.

(Noise may be generated depending on the conditions

under which the electric wave is generated, even if 1 metre

is kept.)

(2) When using suspension bolts for installation, the hanging

brackets must be installed. Confirm that the ceiling is strong

enough to support the weight of the indoor unit.

(3) If the installation requires the indoor unit to be exposed

please ensure the unit is more than 1.8m above the floor so

that children can not touch the unit.

(4) A suitable air filter (field supplied) must be installed within the

return air duct.

PREPARATIONS BEFORE INSTALLATIONTo facilitate installation, the indoor unit can be easily separated

into smaller parts to make it easier to move to the final position.

See page 15 for details.

(1) Refer to Table 1 and Fig 3 for suspension bolt positionand horizontal (top view) representation of the indoorunit.

(2) The external static pressure setting for the indoor

unit is factory set to “standard” external static

pressure.For installations with a duct system that

presents a high external static pressure, set the static

pressure value to the “high” position. Refer to page 12

in this manual and the fan performance curves in the

Engineering Data.

NOTE Additional thermal insulation material (thickness 10mm or more of glass wool or polyethylene foam) may be

required if the conditions in the ceiling exceeds 30oC and RH 80% or outside air is introduced into the ceiling or the

unit operates for 24 hours. It is also important that a safety drain tray be used. (see Fig.12)

WARNING

• Cut off the ends of the plugs before heating in order

to release pressure, otherwise the plugs may

burst. (Fig. 7)

• Ensure a wet cloth is wrapped around the copper pipe

before applying a flame to prevent burning of felt

insulation. (Fig. 7 and 8)

• Take extreme care not to burn the air conditioner body

when brazing.

Applies to FDYQ200P & FDYQN200P models only:

• Cut off the end of both plugs before heating the liquid pipe

to remove the liquid pipe plug.

• Using tube cutters (1/8 - 1 1/8) cut the 22.2mm gas pipe plug

approximately 25mm or more from the expanded section of

the pipe. (Fig. 7)

• Remove the burr from the inlet of the gas pipe. ENSURE all

copper shavings are removed

• Insert 19.1mm field supplied gas pipe into the 22.2mm

pipe previously cut. Insertion length must be at least 12mm.

(Fig. 8)

• Braze joint A as shown in Fig. 8. To ensure joint (B) has not

been disturbed by the heating of joint (A) reheat joint (B)

and apply solder if necessary.

• Braze the liquid line joint.

Applies to all models except FDYQ200P & FDYQN200P

• Cut the end of the plugs before heating the pipes to

remove the plugs. (Fig. 7a)

• Braze the pipes as shown in Fig. 8a.

Applies to all models.

• Ensure the pipe insulation is sealing against the body.

(Fig. 9)

• Install the clamps (field supplied) as close to the body as

possible to absorb leaking condensation. (Fig. 10)

• Prevent any mixture of air into the refrigerant.

• Ensure sufficient ventilation if the refrigerant leaks during

installation work.

• Make sure to completely insulate the connecting pipe

work and connections using field supplied insulation after

checking for gas leakage.

• When in heating mode, the temperature of gas piping

may reach 120°C. Ensure that the insulation will safely

withstand 120°C.

Caution to be taken when brazing refrigerant piping

Do not use flux when brazing refrigerant piping. Use the

phosphor copper brazing filler metal (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, particularly

if the flux contains fluorine, it will damage the refrigerant

oil.)

During any brazing of the refrigerant piping, you must

continually blow dry nitrogen gas through the piping to

expel air from the piping. (see Fig. 11) If you braze the

piping without doing so, a large amount of oxide film

develops inside the piping which can cause system failure.

Ensure that you use a pressure reducing valve on the dry

nitrogen bottle to prevent pinholes caused by excessively

high pressure. (Set the pressure of nitrogen gas to about

0.2 kg / cm2 [19.6 kPa])

EDAU01 - 410

DRAIN PIPING WORK

WARNING

The drain pipe must be installed as shown in the diagram below to avoid water damage caused by

leaks and condensation.

• Assemble the unit as shown in Fig. 12.

• For best results, try to keep the piping as short as possible. Slant the piping at an angle to improve flow (the

drain pipe provided with the indoor unit has a PT 3/4 internal thread). Fig. 12.

• Securely insulate the drain pipe.

• It is necessary to provide a drain trap in the drain outlet to relieve negative pressure that exists within the unit

compared to the outside atmospheric pressure when the unit is operating. If a drain trap is not provided,

condensation carry over or an odour may occur.

• Keep pipes as straight as possible for easy cleaning and to prevent the accumulation of dirt and debris.

• Pour water in the drain pan to test the drainage.

• Always use an extra safety drain pan (field supplied) to cover the entire area of the indoor unit.

• Insulate drain pipe using piping thermal insulation to prevent condensate dripping during humid conditions.

CAUTION

Drain piping connections. Do not connect the drain piping directly to sewage pipes. Drainage must conform to

local plumbing regulations.The vapour in the sewage might enter the indoor unit through the drain pipes and

corrode the heat exchanger or escape into the room.

Forced OFF or ON-OFF control by external control

If required, external control (eg. fire trip, external timer, etc) can be applied by connecting the switching device to

terminals (T1 & T2) as shown in Fig 17. The functionality of the control is set and configured under field settings

on page 13.

CAUTION

Precautions for wiring

• When connecting the indoor unit, give consideration to the other electrical equipment connected to the main

breaker and select the phase (L1, L2, L3) so that current (or voltage) unbalance does not occur. If current

unbalance occurs, the phase current of the compressor may become unbalanced and there is a risk of

protective device actuating or compressor breakdown.

• Do not clamp the remote controller cord or F1/F2 cord together with electrical wires. Doing so may cause a

malfunction.

• Remote controller cords and wires connecting the units should be located at least 50 mm from other electric

wires. Not following this guideline may result in malfunction due to electrical noise.

• Use a round crimp-style terminal for connection to the power supply terminal board. (Fig. 15) Where this is not

possible due to unavoidable reasons, be sure to observe the following instructions.

Do not connect wires of different gauge to the same power supply terminal. (Fig. 16). Looseness in the

connection will cause overheating.

When connecting wires of the same gauge, connect them according to the figure below.

• Make certain that prescribed wires are used, carry out complete connections, and secure the wires so that

outside forces are not transmitted to the terminals.

• Shielded wire is recommended for transmission wiring to comply with EMI (AS/NZSCISPR14.1)

• Use double insulation wire for the remote controller and ON-OFF Input T1, T2 (Sheath thickness is 1mm or

more) or run wires through a wall or conduit so that the user cannot come in contact with them.

• Run transmission wiring separate from power supply wiring. Ensure transmission and power supply wiring is

protected by conduit against external forces.

• After connecting the wires, be sure that no pressure is applied to the wire connections by using cable ties and

securing them to the anchor points. Also, when wiring, make sure the lid of the terminal box fits snugly by

arranging the wires neatly and attaching the terminal box lid firmly. When attaching the terminal box lid, make

sure no wires get caught under the edges.

• Make sure the remote control cord or the wiring between the units (ie F1/F2) do not pass through the same

locations outside the unit as any other electrical wiring. Separate them by at least 50 mm, otherwise electrical

noise could cause a malfunction or damage to the unit. 50mm is considered the minimum for domestic

applications where there is relatively low current flowing in other electrical wiring. In applications where high

current or voltage is present in nearby electrical wiring additional separation will be required.
