fall,

 

or result in water leakage,

 

electrical 

shock,

 

or

 

fire.

Install

 

in

 

a

 

strong,

 

firm

 

location

 

that

 

can

 

withstand the

 

entirety of 

the set's

 

weight.

If

 

the structural

 

integrity

 

is insufficient,

 

or

 

installation

 

is

improperly

 

done, the

clamp

 

the

cable so

 

that

 

no

 

external

 

force

 

will

 

be

 

acted

 

upon

 

the

 

terminal. If

 

the connections

 

or

 

fixtures

 

are

 

not

 

perfect,

 

it

 

can

 

cause

 

heat-up

 

and

 

eventual fire at

 

the

Precautions

 

for

 

Location Selection

1)

 

Choose

 

a

 

place

 

sturdy

 

enough

 

to

 

bear

 

the

 

weight

 

and

 

vibration

s

 

of

the

 

unit,

 

and

 where

 

the

 

operation

 

noise

 

will

 

not

 

be

 

amplified.

2)

 

Choose

 

a

 

location

 

where 

neither

 

the

 

hot

 

air

 

discharged

 

from

 

the

       unit

 

n

or the

 

operation

 

noise

 

will

 

cause

 

a

 

nuisance

 

to

 

the

 

 

       neighbors of

 

the

 

user.

3)

 

Avoid

 

places

 

near

 

bedroom

s

 

and

 

the

 

like,

 

so

 

that

 

the

 

operation

noise

 

will

 

cause

 

no

 

disturbances.

4)

 

There

 

must

 

be

 

sufficient

 

space

 

for

 

carrying

 

the

 

unit

 

into

 

and

 

out

 

from

 the

 

site.

5)

 

There

 

must

 

be

 

sufficient

 

space

 

for

 

air

 

passage,

 

and

 

no

obstructions

 

around

 

the

 

air

 

inlet

 

and

 

the

 

air

 

outlet.

6)

 

The

 

site

 

must

 

be

 

free

 

from

 

the

 

poss心lity

 

of

 

flammable

 

gas

leakage

 

in

 

a

 

nearby

 

place.

7)

 

Install

 

units,

 

power

 

cords,

 

and

 

inter-unit

 

wire

 

at

 

least

 

3m

 

away

 

  

       from television

 

and

 

radio

 

sets.

 

This

 

is

 

to

 

prevent

 

interference

 

from

 

       images 

 

and

 

sounds.

 

(Noises

 

may

 

be

 

heard

 

even

 

if

 

they

 

are

 

more

 

       than

 

3m 

 

away,

 

depending

 

on

 

radio

 

wave

 

cond仆ions.)

8)

 

In

 

coastal

 

areas,

 

or

 

other

 

places

 

with

 

salty

 

atmosphere,

 

o

r

 

sulfate

gas,

 

corrosion

 

may

 

shorten

 

the

 

life

 

of

 

the

 

air

 

conditioner.

9)

 

Since

 

drain

 

flows

 

out

 

of

 

the

 

outdoor

 

unit,

 

do

 

not

 

place

 

anything 

 

      underneath the 

unit that

 

must

 

be

 

kept

 

away

 

from

 

moisture

NOTE:

 

Cannot

 

be

may

be

 

exposed

 

directly

 

to

 

wind.

-

 

To

 

prevent

 

exposure

 

to

 

wind,

 

it

 

is

 

recommended

 

to

 

install

 

a

 

baffle

plate

reach up to approximately 120'C/248 F. Use insulation that has

sufficient resistance.)

•

Also, in cases where the temperature and humidity of the

°

refrigerant piping sections might exceed 30'C/86 F or Rh80%,

reinforce the refrigerant insulation (by 20mm/0.8in, or thicker).

Condensation may form on the surface of the insulating material.

•

Before rigging tubes, check which type of refrigerant is used

•

Use a pipe cutter and flare suitable for used refrigerant.

•

Only use annealed material for flare conncetions.

•

Do not mix anything other than the specified refrigerant, such

as air, etc.., into the refrigerant circuit.

•

If the refrigerant gas leaks during the work, ventilate the area.

A toxic gas is at risk of being emitted by the refrigerant gas if

exposed to a fire.

•

Make sure there is no refrigerant gas leak. A toxic gas may be

released by the refrigerant gas leaking indoors and being

exposed to flames from an area heater, cooking stove, etc.

•

Refer to the table below for the dimensions of flare nuts spaces

and the appropriate tightening torque. (Overtightening may

Air Evacuation

9

Preparations and Precautions

can cause abnormal rises in pressure, which 
can damage the air conditioner, reduce its 
efficiency,  and cause injury. Use a vacuum pump 
and manifold gauge to evacuate the line set and the  
indoor unit, removing any non-condensable gas 
and moisture from the system.

Evacuation should be performed upon initial 
installation, and when unit is relocated.

BEFORE PERFORMING EVACUATION



Check to make sure that both LIQUID
SIDE and GAS SIDE pipes between 
the indoor and outdoor units are 
connected properly, in accordance with the 
Refrigerant Piping Connection section of 
this manual.



Check to make sure all wiring is connected
properly.

Evacuation Instructions

Before using the manifold gauge and vacuum 
pump, read their operation manuals to familiarize 
yourself with how to use them properly.

Caution: Systems are precharged with refrigerant (entire amount necessary for the system set has been 
charged into the outdoor section). The line sets and the indoor units are not charged, and must be evacuated
prior to releasing the refrigerant from the outdoor unit to the rest of the system.
Do NOT open the valves of the 2 service ports on your outdoor unit until the air evacuation is completed
successfully, and thw system passes leak checks. BOTH of those Service valves MUST BE OPENED to release the
refrigerant before turning the system ON. Operating the system with service valves closed will result in 
compressor damage.

Evacuation

3.

Open the BLUE (Low Pressure) valve of Manifold
Gauge. Keep the RED (High Pressure) valve closed.

4.

Turn the vacuum pump ON to start evacuating the
air from the line set and indoor unit circuits.

5.

Run the vacuum pump for at least 15 minutes, or
until the Low Pressure Gauge reads -76cmHG
(-100 kPa or -30 In Hg). (Negative value)

6.

Close the Blue (Low Pressure) valve of Manifold
Gauge, then turn the vacuum pump OFF.

7.

Wait for 5 minutes, then check that there has
been no rise in Low Pressure Gauge reading.

8.

If there is a rise (Vacuum Loss), refer to  the
Gas Leak Check section for information
on how to check for leaks. If there is no
change in vacuum reading, unscrew the cap
from the LIQUID Side Service Valve (Fig. 6.2)

9.

Insert a hexagonal wrench into the service valve
(LIQUID Side Valve), and open the valve by
turning the wrench in a 1/4 counterclockwise
turn. Listen for the sound of gas exiting the
system, then close the valve after 5 seconds.

10.  

Watch the Pressure Gauge for a few minutes,
to make sure that there is no drop in the
pressure value (indicating a leak)

The Low Pressure Gauge should now show

a positive pressure value (Above Zero).

11.  

Remove the charging hose from the service port.

12.

Using a hexagonal wrench, fully open both the 
LIQUID side and GAS side Service Calves.

13.

Tighten valve caps on all three valves (service
port, liquid side, gas side) by hand.
Then,  tighten it further using a torque
wrench, if needed.

 OPEN VALVE STEMS GENTLY

When opening valve stems, turn the hexagonal 
wrench until it seats against the stopper. Do not 
try to force the valve to open further.

Some systems require additional charging depending on pipe lengths. The pipe length varies according
to locations of the indoor and outdoor units. The system has been factory charged with sufficient R410a
refrigerant for the standard pipe length of 5m (~16‘). The additional refrigerant to be charged can be 
calculated using the following formula. This is necessary only if the length exceeds 7.5m (25 feet).

For local insulation, be sure to insulate local piping

all the way into the pipe connections inside the unit.

Exposed piping may cause condensation, or may

cause burns when touched.

Make sure that no oil remains on plastic parts of the

decoration panel (optional equipment).
Oil may cause degradation and damage to plastic
parts.

4.2 

Install the drain pipes.

Keep piping as short as possible, and slope it downwards at

a gradient of at least 1/100 so that air may not remain
trapped inside the pipe.

Keep pipe size equal to or greater than that of the connecting

pipe (PVC pipe, nominal diameter 20mm/0.8in in, outside
diameter 25mm/1in).

- Push the drain hose as far as possible over the drain socket,

Precautions

Install the drain raising pipes at a height

lower

than 530

mm/20.9 in.

Install the drain raising pipes at a right angle to the indoor unit,

and no more than 300 mm/11.8 in. from the unit.

- To prevent air bubbles, install the drain hose level, or slightly

 tilted up ('i,75 mm/3 in.).

- The incline of 

the

d

「

ain hose should be 75 mm/3 in. o

「

less, so

that the drain socket does not have to withstand additional force.

To ensure a downward slope of 1:100, install hanging

bars every 1m/3.3ft to 1.5 m/4.9ft.

When unifying multiple drain pipes, install the pipes asshown in 

the

figure below. Select converging drain pipes whose gauge is
