Installation

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

Illustrations show R(Y)(P)125 outdoor unit type. Other types
also follow this installation manual.

This outdoor unit requires the pipe branching kit (optional) when
used as the outdoor unit for the simultaneous operation system.
Refer to catalogues for details.

Never operate the unit without the thermistor (R3T), burning of
the compressor may result.

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 Nm.

Handling

As shown in the figure, bring the unit slowly by grabbing the left and
right grips. (Take care not to let hands or things come in contact with
rear fins.)

EFORE

INSTALLATION

Precautions

For R407C units only

The new 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 "Precautions on refrigerant piping" on page 4 carefully and
follow these procedures correctly.
Since design pressure is 3.3 MPa or 33 bar (for R22 units

3.0 MPA or 30 bar), pipes of larger wall thickness may be
required.

Since R407C 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 R407C. If indoor units for R22 are connected,
normal operation cannot be assured.

S

ELECTING

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

- Places where there is no possibility of flammable gas or

- Places where servicing space can be well ensured.

- Places where the indoor and outdoor units' piping and wiring

- Places where water leaking from the unit cannot cause

Precautions

Do not install or operate the unit in rooms mentioned below.

Where mineral oil like cutting oil is present.
Where the air contains high levels of salt such as that near the

ocean.
Where sulphurous gas is present such as that in areas of hot

spring.
Where voltage fluctuates a lot such as that in factories.
In vehicles or vessels.
Where high concentrations of oil vapour or spray are present

such as that in kitchens.
Where machines generating electromagnetic waves are

present.
Where acidic or alkaline vapour is present.

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.

Turn the air outlet side toward the building's wall, fence or
screen.

- Remove the rear suction grille to prevent snow from
accumulating on the rear fins.

If you install the unit on a building frame, please install a
waterproof plate (within 150 mm of the underside of the unit) in
order to avoid the drainwater dripping. (See figure).

P

RECAUTIONS

Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after
installation.

In accordance with the foundation drawing in the figure, fix the
unit securely by means of the foundation bolts. (Prepare four
sets of M12 foundation bolts, nuts and washers each which are
available on the market.)

It is best to screw in the foundation bolts until their length are
20 mm from the foundation surface.

performed with less field piping, the system will be overcharged
(abnormal HP, etc.). If the distance between indoor and outdoor unit
is less than 7.5 m, please make sure that the piping length is ≥ 7.5 m
by additional bending of the pipes.

PRECAUTIONS ON REFRIGERANT PIPING

When a heat pump outdoor unit is installed below the indoor unit, the
following can occur:

■ when the unit stops, oil will return to the discharge side of the
compressor. When starting the unit, this can cause liquid (oil)
hammer.

■ the oil circulation will decrease

To solve these phenomena, provide oil traps in the gas pipe every
15 m if the level difference (H) is more than 15 m. (See figure 5)

A outdoor unit
B indoor unit
C gas pipe
D liquid pipe
E oil trap

NOTE

If the outdoor unit is installed above the indoor unit, oil
traps are not necessary.

NOTE

■ Refer to the table for stop valve tightening
torques.

■ Be sure to use both a spanner and a torque
wrench when connecting or disconnecting pipes
to or from the unit.

■ Use a charging hose with push rod when using
the service port (5).

■ Check for refrigerant gas leakage after tightening
the cap.

■ Make sure to keep the valve open during
operation.

Precautions for connecting pipes

When the outdoor unit is installed above the indoor unit the following
can occur:

1 The condensated water on the stop valve can move to the

indoor unit. To avoid this, please cover the stop valve with
sealing material.

For R407C units:

Use R407C only when adding refrigerant
Installation tools:
Make sure to use installation tools (gauge manifold charge

hose, etc.) that are exclusively used for R407C
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 mmHg).

Operating stop valve: see figure 6

To open:

1 Remove the cap (1) and turn the shaft (2) counterclockwise with

hexagon socket screw keys.

2 Turn it all the way until the shaft stops.

3 Tighten the cap firmly.

To close:

1 Remove the cap and turn the shaft clockwise.

2 If the temperature is higher than 30°C and the humidity is higher

than RH 80%, then the thickness of the sealing materials should
be at least 20 mm in order to avoid condensation on the surface
of the sealing.

■ Please refer to the table for the dimensions for processing flares
and for the tightening torques. (Too much tightening will end up
in splitting of the flare.)

■ When connecting the flare nut, coat the flare both inside and
outside with refrigerant oil (R22), ether or ester oil (R407C) and
initially tighten by hand before tightening firmly.

■ Make sure to flow nitrogen gas through the pipe when brazing.

In case of simultaneous operation system

■ Upward and downward piping should be performed at the main
piping line.

■ Use branch piping kit (optional) for branching refrigerant pipes.

Precautions to be taken. (For details, refer to the manual attached to
branch piping kit.)

- Install the branch pipes horizontally. (Maximum inclination:

20° or less)

- Length of branch pipe to the indoor unit should be as short as

possible.

- Try to keep lengths of both branch pipes to the indoor unit

equal.

EVACUATING

Leak test

1 Evacuate the pipes and check vacuum. (No pressure increase

for 1 minute.)

2 Break the vacuum with a minimum of 2 bar of nitrogen.

3 Conduct leak test by applying soap water, etc. to the connecting

part of the pipes.

4 Discharge nitrogen.

5 Evacuate and check vacuum again.

6 Open the stop valve and inject the refrigerant into the refrigerant

pipe and into the indoor unit.

7 Leak test must satisfy EN 378-2.

The units were checked for leaks by the manufacturer.

The refrigerant lines fitted in site are to be checked for leaks by the
fitter.

Confirm that the valves are firmly closed before pressure test or
vacuuming.

Do not purge the air with refrigerants. Use a vacuum pump
to vacuum the installation. No additional refrigerant is
provided for air purging.

Air tight test and vacuum drying (take special care for R407C units):

9 Pipe branching kit (optional)

■ Air tight test: make sure to use nitrogen gas. Pressurize the
liquid and gas pipes to 3.3 MPa (do not pressurize more than

3.3 MPa). If the pressure drops, check where the nitrogen
comes from.

■ Vacuum drying: use a vacuum pump which can evacuate to

-100.7 kPa (5 Torr, -755 mmHg).

- Evacuate the system from the liquid and gas pipes by using a

vacuum pump for more than 2 hours and bring the system to

-100.7 kPa. After keeping the system under that condition for
more than one hour, check if the vacuum gauge rises or not.
If it rises, the system may either contain moisture inside or
have leaks.

- Following should be executed if there is a possibility of

moisture remaining in the pipe (if piping work is carried out
during the raining season or over a long period of time,
rainwater may enter the pipe during work).

- After evacuating the system for 2 hours, pressurize the

system to 0.05 MPa (vacuum break) with nitrogen gas and
evacuate the system again using the vacuum pump for
1 hour to -100.7 kPa (vacuum drying). If the system cannot
be evacuated to -100.7 kPa within 2 hours, repeat the
operation of vacuum break and vacuum drying. Then after
leaving the system in vacuum for 1 hour, confirm that the
vacuum gauge does not rise.

CHARGING REFRIGERANT

This unit requires additional charging of refrigerant according to the
length of pipe connected at the site. Concerning R407C refrigerant:
charge the refrigerant to the liquid pipe in its liquid state. Since
R407C is a mixed refrigerant, its composition changes if charged in a
state of gas and normal system operation would no longer be
assured.

Concerning L1~L4 (see following tables), refer to figure 2~figure 4.

Additional charging of refrigerant

Find the correct amount of additional refrigerant to charge 'G' (kg)
using one of the following formulas.

Complete charging of the refrigerant

When the entire refrigerant pipe length is within 30 meters (for
R407C) and 7.5 meters (for R22), charge the refrigerant in
accordance with the amount mentioned in the nameplate, and when
the pipe length exceeds 30 meters (for R407C) and 7.5 meters (for
R22), the charging amount mentioned in the nameplate and that
required for additional charging are to be totalled as the net charging
amount.

Precaution for pumping-down operation

The outdoor unit is equipped with a low-pressure switch to protect the
compressor. Take the following steps to perform the pumping-down
operation.

Never short-circuit the low-pressure switch in this
operation.

In order to avoid electric shock, please put the insulation
sheet as follows. (See figure 8)

1 Switch box
2 PCB
3 Pump down button
4 Insulation sheet
5 Tape

1 Start the fan operation with the remote controller.

Confirm that stop valves both on the liquid and gas side are open.

2 Push the pumping-down button on the PC board of the outdoor

unit during more than 5 seconds.
Compressor and outdoor fan will start operation automatically.

If step 2 is performed before step 1, then the indoor fan may
automatically start running. Please pay attention to this.

3 Continue operation for 2 min. until operation condition stabilizes.

4 Close the stop valve on the liquid side securely. (See "Operating

stop valve: see figure 6" on page 4)

Insecure closing of the valve may result in burning of the
compressor.

5 When the low-pressure switch is activated, the unit stops

working. At this time, close the stop valve on the gas side.

This is the end of pumping-down operation. After pumping-down
operation, the remote controller can show the following pattern:

- "U4"

- blank screen

- indoor fan operates for about 30 seconds

even when ON button on the remote controller is pressed, and it will
not operate. Turn off the main power supply switch and turn it on
again in need of operation.

■ All wiring must be performed by an authorized electrician.

■ All components procured on the site and all electric construction

should comply with the applicable local and national codes.

■ Be sure to use a dedicated power circuit.

■ Do not share a common source with other equipment.

■ Fix cables so that cables do not make contact with the pipes

(especially on high pressure side).

■ For W1 and T1 models
Make sure to connect power supply cables in normal phase. If
connected in reverse phase, the remote controller of indoor unit
indicates "U1" and the equipment cannot operate. Change any
two of the three power supply cables (L1, L2, L3) to correct
phase.
If the contact in the magnetic switch should be forcibly turned on
while the equipment is inoperative, the compressor will burn out.
Never try to forcibly turn on the contact.

■ Never squeeze bundled cables into a unit.

■ When cables are routed from the unit, a protection sleeve for the

conduits (PG-insertions) can be inserted at the installation hole.
