Drain Joint Installation
Notes On Drilling Hole In Wall
If the drain joint comes with a rubber seal (see
Fig. 5.12 - A), do the following:
1. Fit the rubber seal on the end of the drain
joint that will connect to the outdoor unit.
The drainpipe is used to drain water from the
unit. Improper installation may cause unit and
property damage.
You must drill a hole in the wall for the refriger-
ant piping, and the signal cable that will con-
nect the indoor and outdoor units.
1. Determine the location of the wall hole
based on the location of the outdoor unit.
2. Using a 65-mm (2.5”) core drill, drill a hole in
the wall.
NOTE: When drilling the wall hole, make
sure to avoid wires, plumbing, and other
sensitive components.
3. Place the protective wall cuff in the hole.
This protects the edges of the hole and will
help seal it when you finish the installation
process.
Indoor Drainpipe Installation
Install the drainpipe as shown in Figure 6.2.
1. Cover the drainpipe with heat insulation to
prevent condensation and leakage.
2. Attach the mouth of the drain hose to the
unit’s outlet pipe. Sheath the mouth of the
hose and clip it firmly with a pipe clasp.
(Fig 6.1)
2. Insert the drain joint into the hole in the
base pan of the unit.
3. Rotate the drain joint 90° until it clicks in
place facing the front of the unit.
4. Connect a drain hose extension (not includ-
ed) to the drain joint to redirect water from
the unit during heating mode.
If the drain joint doesn’t come with a rubber
seal (see Fig. 5.12 - B), do the following:
1. Insert the drain joint into the hole in the
base pan of the unit. The drain joint will click
in place.
2. Connect a drain hose extension (not includ-
ed) to the drain joint to redirect water from
the unit during heating mode.
6
Drainpipe Installation
CAUTION
• Insulate all piping to prevent condensation
and water damage.
• If the drainpipe is bent or installed incorrectly,
water may leak and cause a malfunction of
the water-level switch.
• In HEAT mode, the outdoor unit will discharge
water. Ensure that the drain hose is placed in
an appropriate area to avoid water damage
and slippage due to frozen drain water.
• DO NOT pull the drainpipe forcefully as this
could cause it to disconnect.
NOTE ON PURCHASING PIPES
This installation requires a polyethylene
tube (outside diameter = 3.7-3.9cm, inside
diameter = 3.2cm), which can be obtained
at your local hardware store or dealer.
NOTE ON DRAINPIPE INSTALLATION
• When using an extended drainpipe, tighten
the indoor connection with an additional pro-
tection tube to prevent it from pulling loose.
• The drainpipe should slope downward at a
gradient of at least 1 /100 to prevent water
from owing back into the air conditioner.
• To prevent the pipe from sagging, space
hanging wires every 1 -1.5m (39-59”).
• Incorrect installation could cause water to
ow back into the unit and ood it.

◄ Page 18 ► ◄ Page 19 ►
3. Using a 65-mm (2.5”) core drill, drill a hole in
the wall. Make sure that the hole is drilled at
a slight downward angle, so that the outdoor
end of the hole is lower than the indoor end
by about 12mm (0.5”). This will ensure proper
water drainage (See Fig. 6.4). Place the pro-
tective wall cuff in the hole. This protects the
edges of the hole and will help seal it when
you finish the installation process.
4. Pass the drain hose through the hole.
Make sure the water drains to a safe location
where it will not cause water damage or a
slippage.

NOTE: When drilling the hole in the wall,
make sure to avoid wires, plumbing, and oth-
er sensitive components.
NOTE: The drainpipe outlet should be at least
5cm (1.9”) above the ground. If it touches the
ground, the unit may become blocked and
malfunction. If you discharge the water direct-
ly into a sewer, make sure that the drain has a
U or S pipe to prevent unwanted odors from
entering the house.

Refrigerant Piping Connection
Safety Precautions Notes On Pipe Length and Elevation
WARNING
• All eld piping must be completed by a
licensed technician and must comply with the
local and national regulations.
• When the air conditioner is installed in a small
room, measures must be taken to prevent
the refrigerant concentration in the room
from exceeding the safety limit in the event
of refrigerant leakage. If the refrigerant leaks
and its concentration exceeds its proper limit,
hazards due to lack of oxygen may result.
• When installing the refrigeration system,
ensure that air, dust, moisture or foreign sub-
stances do not enter the refrigerant circuit.
Contamination in the system may cause poor
operating capacity, high pressure in the refrig-
eration cycle, explosion or injury.
• Ventilate the area immediately if there is
refrigerant leakage during the installation.
Leaked refrigerant gas is both toxic and am-
mable. Ensure there is no refrigerant leakage
after completing the installation work.
Ensure that the length of the refrigerant pipe,
the number of bends, and the drop height be-
tween the indoor and outdoor units meets the
requirements shown in Table 7.1:

Refrigerant Piping Connection Instructions
CAUTION
• The branching pipe must be installed hor-
izontally. An angle of more than 10° may
cause malfunction.
• DO NOT install the connecting pipe until both
indoor and outdoor units have been installed.
• Insulate both the gas and liquid piping to
prevent water leakage.
CAUTION
DO NOT deform pipe while cutting. Be ex-
tra careful not to damage, dent, or deform
the pipe while cutting. This will drastically
reduce the heating eciency of the unit.
CAUTION
• Ensure to wrap insulation around the piping.
Direct contact with the bare piping may result
in burns or frostbite.
• Make sure the pipe is properly connected. Over
tightening may damage the bell mouth and
under tightening may lead to leakage.
CAUTION
Check to make sure there is no refrigerant leak
after completing the installation work. If there
is a refrigerant leak, ventilate the area immedi-
ately and evacuate the system (refer to the Air
Evacuation section of this manual).
Step 1: Cut pipes
When preparing refrigerant pipes, take extra
care to cut and flare them properly. This will
ensure efficient operation and minimize the
need for future maintenance.
1. Measure the distance between the indoor
and outdoor units.
2. Using a pipe cutter, cut the pipe a little
longer than the measured distance.
Step 2: Remove burrs.
Burrs can affect the air-tight seal of refrigerant
piping connection. They must be completely
removed.
1. Hold the pipe at a downward angle to pre-
vent burrs from falling into the pipe.
2. Using a reamer or deburring tool, remove
all burrs from the cut section of the pipe.
Step 3: Hare pipe ends
Proper flaring is essential to achieve an airtight
seal.
1. After removing burrs from cut pipe, seal
the ends with PVC tape to prevent foreign
materials from entering the pipe.
2. Sheath the pipe with insulating material.
3. Place flare nuts on both ends of pipe. Make
sure they are facing in the right direction,
because you can’t put them on or change
their direction after flaring. See Fig. 7.4
4. Remove PVC tape from ends of pipe when
ready to perform flaring work.
5. Clamp flare form on the end of the pipe.
The end of the pipe must extend beyond
the flare form.
6. Place flaring tool onto the form.
7. Turn the handle of the flaring tool clock-
wise until the pipe is fully flared. Flare the
pipe in accordance with the dimensions
shown in table 7.3.
8. Remove the flaring tool and flare form,
then inspect the end of the pipe for cracks
and even flaring.
Step 4: Connect pipes
Connect the copper pipes to the indoor unit
first, then connect it to the outdoor unit. You
should first connect the low-pressure pipe,
then the high-pressure pipe.
1. When connecting the flare nuts, apply a
thin coat of refrigeration oil to the flared
ends of the pipes.
2. Align the center of the two pipes that you
will connect.
6. After connecting the copper pipes to the
indoor unit, wrap the power cable, signal
cable and the piping together with binding
tape.
7. Thread this pipeline through the wall and
connect it to the outdoor unit.
8. Insulate all the piping, including the valves
of the outdoor unit.
9. Open the stop valves of the outdoor unit
to start the flow of the refrigerant between
the indoor and outdoor unit.
3. Tighten the flare nut as tightly as possible
by hand.
4. Using a spanner, grip the nut on the unit
tubing.
5. While firmly gripping the nut, use a torque
wrench to tighten the flare nut according
to the torque values in table 7.5.
1. Make sure that the pipe is cut at a perfect
90° angle. Refer to Fig. 7.2 for examples of
bad cuts

Air Evacuation
Safety Precautions
Evacuation Instructions
CAUTION
• Use a vacuum pump with a gauge reading low-
er than -0.1 MPa and an air discharge capacity
above 40L/min.
• The outdoor unit does not need vacuuming. DO
NOT open the outdoor unit’s gas and liquid stop
valves.
• Ensure that the Compound Meter reads -0.1
MPa or below after 2 hours. If after three hours
of operation and the gauge reading is still above
-0.1 MPa, check if there is a gas leak or water
inside the pipe. If there is no leakage, perform
another evacuation for 1 or 2 hours.
• DO NOT use refrigerant gas to evacuate the
system.
Before using a manifold gauge and a vacuum
pump, read their operation manuals to make
sure you know how to use them properly.
Some systems require additional charging depending on pipe lengths. The standard pipe length
varies according to local regulations. For example, in North America, the standard pipe length
is 7.5m (25’) In other areas, the standard pipe length is 5m (16’). The additional refrigerant to be
charged can be calculated using the following formula:
Manifold Gauge
Compound gauge
-76cmHg
Low pressure valve
Charge hose
Pressure gauge
Flare nut
Cap
Valve stem
Valve body
High pressure valve
Charge hose
Vacuum pump
Low pressure valve Fig. 9.1
Fig. 9.2
1. Connect the manifold gauge’s charge hose
to the service port on the outdoor unit’s low
pressure valve.
2. Connect the manifold gauge’s charge hose
from the to the vacuum pump.
3. Open the Low Pressure side of the manifold
gauge.Keep the High Pressure side closed.
4. Turn on the vacuum pump to evacuate the
system.
5. Run the vacuum for at least 15 minutes, or
until the Compound Meter reads -76cmHG
(-1x105Pa).
6. Close the manifold gauge’s Low Pressure
valve and turn off the vacuum pump.
7. Wait for 5 minutes, then check that there has
been no change in system pressure.
8. Insert hexagonal wrench into the packed valve
(high pressure valve) and open the valve by
turning the wrench 1/4 counterclockwise. Lis-
ten for gas to exit the system, then close the
valve after 5 seconds.
12. Tighten valve caps by hand, then tighten it
using the proper tool.
9. Watch the Pressure Gauge for one minute to
make sure that there is no change in pressure. It
should read slightly higher than the atmospher-
ic pressure.
10. Remove the charge hose from the service port.
11. Using hexagonal wrench, fully open both the
high pressure and low pressure valves.
NOTE: If there is no change in system pres-
sure, unscrew the cap from the packed valve
(high pressure valve). If there is a change in
system pressure, there may be a gas leak.
OPEN VALVE STEMS GENTLY
When opening valve stems, turn the hexago-
nal wrench until it hits against the stopper. DO
NOT try to force the valve to open further.
CAUTION
• Refrigerant charging must be performed after wiring, vacuuming, and the leak testing.
• DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system. Doing so
can damage the unit or impact it’s functioning.
• Charging with unsuitable substances may cause explosions or accidents. Ensure that the appropriate
refrigerant is used.
• Refrigerant containers must be opened slowly. Always use protective gear when charging the system.
• DO NOT mix refrigerants types.
• For the R290 or R32 refrigerant model, make sure the condtions within the area have been made safe
by control of ammable material when the refrigerant added into air conditioner.
• The maximum refrigerant charge amount of R32 is 305 grams.

being carried out. work in confined sapces shall be avoided. The area around the work space shall be
sectioned off. Ensure that the conditions within the area have been made safe by control of flammable
material.
4. Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure
the technician is aware of potentially flammable atmospheres. Ensure that the leak detection equip-
ment being used is suitable for use with flammable refrigerants, i.e. no sparking, adequately sealed or
intrinsically safe.
5. Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate
fire extinguishing equipment shall be available to hand. Have a dry power or C02 fire extinguisher adja-
cent to the charging area.
6. No ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing any pipe
work that contains or has contained flammable refrigerant shall use any sources of ignition in such a
manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette
smoking, should be kept sufficiently far away from the site of installation, repairing, removing and
disposal, during which flammable refrigerant can possibly be released to the surrounding space. Prior
to work taking place, the area around the equipment is to be surveyed to make sure that there are no
flammable hazards or ignition risks. “NO SMOKING” signs shall be displayed.
7. Ventilated area
Ensure that the area is in the open or that it it adequately ventilated before breaking into the system
or conducting any hot work. A degree of ventilation shall continue during the period that the work is
carried out. The ventilation should safely disperse any released refrigerant and preferably expel it exter-
nally into the atmosphere.
8. Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit for the purpose and to the correct
specification. At all times the manufacturer’s maintenance and service guidelines shall be followed.
If in doubt consult the manufacturer’s technical department for assistance. The following checks shall
be applied to installations using flammable refrigerants:
• the charge size is in accordance with the room size within which the refrigerant containing parts are
installed;
• the ventilation machinery and outlets are operating adequately and are not obstructed;
• if an indirect refrigerating circuit is being used, the secondary circuits shall be checked for the pres-
ence of refrigerant; marking to the equipment continues to be visible and legible.
• marking and signs that are illegible shall be corrected;
• refrigeration pipe or components are installed in a position where they are unlikely to be exposed
to any substance which may corrode refrigerant containing components, unless
• the components are constructed of materials which are inherently resistant to being
• corroded or are suitably protected against being so corroded.
9. Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and component
inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be
connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately
but it is necessary to continue operation, and adequate temporary solution shall be used. This shall be
reported to the owner of the equipment so all parties are advised.
Initial safety checks shall include:
• that capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking
• that there no live electrical components and wiring are exposed while charging, recovering or purg-
ing the system;
• that there is continuity of earth bonding.
10.Repairs to sealed components
10.1 During repairs to sealed components, all electrical supplies shall be disconnected from the equip-
ment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to
have an electrical supply to equipment during servicing, then a permanently operating form of leak
detection shall be located at the most critical point to warn of a potentially hazardous situation.
10.2 Particular attention shall be paid to the following to ensure that by working on electrical com-
ponents, the casing is not altered in such a way that the level of protection is affected. This shall
include damage to cables, excessive number of connections, terminals not made to original specifi-
cation, damage to seals, incorrect fitting of glands, etc.
• Ensure that apparatus is mounted securely.
• Ensure that seals or sealing materials have not degraded such that they no longer serve the pur-
pose of preventing the ingress of flammable atmospheres. Replacement parts shall be in accor-
dance with the manufacturer’s specifications.
NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equip-
ment. Instrinsically safe components do not have to be isolated prior to working on them.

◄ Page 32 ► ◄ Page 33 ►
11.Repair to intrinsically safe components
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will
not exceed the permissible voltage and current permitted for the equipment in use. Intrinscially safe
components are the only types that can be worked on while live in the presence of a flammable atmo-
sphere. The test apparatus shall be at the correct rating.
Replace components only with parts specified by the manufacturer. Other parts may result in the igni-
tion of refrigerant in the atmosphere from a leak.
12.Cabling
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or
any other adverse environmental effects. The check shall also take into account the effects of aging or
continual vibration from sources such as compressors or fans.
13.Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition be used in the searching for or detection of
refrigerant leaks. A halide torch(or any other detector using a naked flame) shall not be used.
14.Leak detection methods
The following leak detection methods are deemed acceptable for systems containing flammable
refrigerants. Electronic leak detectors shall be used to detect flammable refrigerants, but the sensi-
tivity may not be adequate, or may need re-calibration.(Detection equipment shall be calibrated in a
refrigerant-free area.) Ensure that the detector is not a potential source of ignition and is suitable for
the refrigerant. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and
shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25% maximum)
is confirmed. Leak detection fluids are suitable for use with most refrigerants but the use of detergents
containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the
copper pipe-work.
If a leak is suspected ,all naked flames shall be removed or extinguished. If a leakage of refrigernat is
found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated(by
means of shut off valves) in a part of the system remote from the leak . Oxygen free nitrogen(OFN) shall
then be purged through the system both before and during the brazing process.
15.Removal and evacuation
When breaking into the refrigerant circuit to make repairs of for any other purpose conventional
procedures shall be used, However, it is important that best practice is followed since flammability is a
consideration. The following procedure shall be adhered to:
• remove refrigerant;
• purge the circuit with inert gas;
• evacuate;
• purge again with inert gas;
• open the circuit by cutting or brazing.
The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be
flushed with OFN to render the unit safe. This process may need to be repeated several times. Com-
pressed air or oxygen shall not be used for this task.
Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until
the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum.
This process shall be repeated until no refrigerant is within the system.
When the final OFN charge is used, the system shall be vented down to atmospheric pressure to en-
able work to take place. This operation is absolutely vital if brazing operations on the pipe-work are to
take place.
Ensure that the outlet for the vacuum pump is not closed to any ignition sources and there is ventila-
tion available.
16.Charging procedures
In addition to conventional charging procedures, the following requirements shall be followed:
• Ensure that contamination of different refrigerants does not occur when using charging equipment.
Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in
them.
• Cylinders shall be kept upright.
• Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
• Label the system when charging is complete(if not already).
• Extreme care shall be taken not to overfill the refrigeration system.
• Prior to recharging the system it shall be pressure tested with OFN. The system shall be leak tested
on completion of charging but prior to commissioning. A follow up leak test shall be carried out
prior to leaving the site.
17.Decommissioning
Before carrying out this procedure, it is essential that the technician is completely familiar with the
equipment and all its detail. It is recommended good practice that all refrigerants are recovered safely.
Prior to the task being carried out, an oil and refrigerant sample shall be taken.
In case analysis is required prior to re-use of reclaimed refrigerant. It is essential that electrical power is
available before the task is commenced.
a) Become familiar with the equipment and its operation.
b) Isolate system electrically
c) Before attempting the procedure ensure that:
• mechanical handling equipment is available, if required, for handling refrigerant cylinders;
• all personal protetive equipment is available and being used correctly;
• the recovery process is supervised at all times by a competent person;
• recovery equipment and cylinders conform to the appropriate standards.
d) Pump down refrigerant system, if possible.
e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various
parts of the system.
f) Make sure that cylinder is situated on the scales before recovery takes place.
g) Start the recovery machine and operate in accordance with manufacturer’s instructions.

◄ Page 34 ► ◄ Page 35 ►
h) Do not overfill cylinders. (No more than 80% volume liquid charge).
i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
j) When the cylinders have been filled correctly and the process completed, make sure that the cylin-
ders and the equipment are removed from site promptly and all isolation valves on the equipment
are closed off.
k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been
cleaned and checked.
18.Labelling
Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The
label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment
contains flammable refrigerant.
19.Recovery
• When removing refrigerant from a system, either for service or decommissioning, it is recommend-
ed good practice that all refrigerants are removed safely.
• When tranferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery
cylinders are employed. Ensure that the correct numbers of cylinders for holding the total system
charge are available. All cylinders to be used are designated for the recovered refrigerant and
labelled for that refrigerant(i.e special cylinders for the recovery of refrigerant). Cylinders shall be
complete with pressure relief valve and associated shut-off valves in good working order.
• Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.
• The recovery equipment shall be in good working order with a set of instructions concerning the
equipment that is at hand and shall be suitable for the recovery of flammable refrigerants. In addi-
tion, a set of calibrated weighing scales shall be available
• and in good working order.
• Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using
the recovery machine, check that it is in satisfactory working order, has been properly maintained
and that any associated electrical components are sealed to prevent ignition in the event of a refrig-
erant release. Consult manufacturer if in doubt.
• The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylin-
der, and the relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units and
especially not in cylinders.
• If compressors or compressor oils are to be removed, ensure that they have been evacuated to an
acceptable level to make certain that flammable refrigerant does not remain within the lubricant.
The evacuation process shall be carried out prior to retruning the compressor to the suppliers. Only
electric heating to the compressor body shall be employed to accelerate this process. When oil is
drained from a system, it shall be carried out safely.
20. Transportation, marking and storage for units
1. Transport of equipment containing flammable refrigerants Compliance with the transport regula-
tions
2. Marking of equipment using signs Compliance with local regulations
3. Disposal of equipment using flammable refrigerants Compliance with national regulations
4. Storage of equipment/appliances
The storage of equipment should be in accordance with the manufacturer’s instructions.
5. Storage of packed (unsold) equipment
Storage package protection should be constructed such that mechanical damage to the equipment
inside the package will not cause a leak of the refrigerant charge.
The maximum number of pieces of equipment permitted to be stored together will be determined by
local regulations.
The design and specications are subject to change without prior notice for product
improvement. Consult with the sales agency or manufacturer for details.
