Fig.3.2
MOUNTING PLATE DIMENSIONS
Different models have different mounting plates.
For the different customization requirements, the
shape of the mounting plate and the dimensions
of the indoor unit may be slightly different.
See Type A and Type B for example:
Correct orientation of Mounting Plate
2.
Using a 65mm (2.5in) or 90mm(3.54in)
(depending on models )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 5mm to 7mm
(0.2-0.275in). This will ensure proper water
drainage.
3.

Step 4: Prepare refrigerant piping
The refrigerant piping is inside an insulating
sleeve attached to the back of the unit. You
must prepare the piping before passing it
through the hole in the wall.
1. Based on the position of the wall hole relative
to the mounting plate, choose the side from
which the piping will exit the unit.
2. If the wall hole is behind the unit, keep the
knock-out panel in place. If the wall hole is to
the side of the indoor unit, remove the plastic
knock-out panel from that side of the unit.
This will create a slot through which your
piping can exit the unit. Use needle nose pliers
if the plastic panel is too difficult to remove by
hand. Groove has been made in the knock-out
panel in order to cut it conveniently. The size of
the slot is determined by the diameter of piping.
3.
If existing connective piping is already
embedded in the wall, proceed directly to
the Connect Drain Hose step. If there is no
embedded piping, connect the indoor unit’s
refrigerant piping to the connective piping
that will join the indoor and outdoor units.
Refer to the Refrigerant Piping Connection
sectionof this manual for detailed instructions.
NOTE ON PIPING ANGLE
Refrigerant piping can exit the indoor unit from
four different angles:Left-hand side,Right-hand
side, Left rear, Right rear.
Knock-out Panel
CAUTION
Be extremely careful not to dent or damage
the piping while bending them away from
the unit. Any dents in the piping will affect
the unit’s performance.
Step 5:
Connect drain hose
By default, the drain hose is attached to the left-
hand side of unit (when you’re facing the back
of the unit). However, it can also be attached to
the right-hand side. To ensure proper drainage,
attach the drain hose on the same side that your
refrigerant piping exits the unit. Attach drain hose
extension (purchased separately) to the end of
drain hose.
Wrap the connection point firmly with Teflon
tape to ensure a good seal and to prevent leaks.
Remove the air filter and pour a small amount
of water into the drain pan to make sure that
water flows from the unit smoothly.
NOTE ON DRAIN HOSE
PLACEMENT
Make sure to arrange the drain hose
according to the following figures.
.
PLUG THE UNUSED DRAIN HOLE
To prevent unwanted leaks
you must plug the unused
drain hole with the rubber
plug provided.
CORRECT
Make sure there are no kinks
or dent in drain hose to ensure
proper drainage.
NOT CORRECT
Kinks in the drain hose
will create water traps.
NOT CORRECT
Do not place the end of the
drain hose in water or in
containers that collect water.
This will prevent proper
drainage.
NOT CORRECT
Kinks in the drain hose
will create water traps.
For the portion of the drain hose that will remain
indoors, wrap it with foam pipe insulation to
prevent condensation.

Air Evacuation
Preparations and Precautions
Air and foreign matter in the refrigerant circuit 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 refrigerant circuit, 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 the connective pipes
between the indoor and outdoor units
are connected properly .
Check to make sure all wiring is connected
properly.

Note on Adding Refrigerant
Some systems require additional charging depending on pipe lengths. The standard pipe length varies
according to local regulations. The refrigerant should be charged from the service port
on the outdoor
unit’s low pressure valve.
For the R290 refrigerant models, no refrigerant can be added.
The additional
refrigerant to be charged can be calculated using the following formula:

dry power or CO2 fire extinguisher adjacent to the charging area.
2. Work procedure
All maintenance sta and others working in the local area shall be instructed on the
nature of work being carried out. work in confined sapces shall be avoided.
Prior to beginning work on systems containing flammable refrigerants, safety checks
are necessary to ensure that the risk of ignition is minimised. For repair to the
refrigerating system, the following precautions shall be complied with prior to
conducting work on the system.
Works shall be undertaken under a controlled procedure so as to minimise the risk
of a flammable gas or vapour being present while the work is being performed.
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 equipment being used is suitable for use with
flammable refrigerants, i.e. no sparking, adequately sealed or intrinsically safe.
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 externally into the atmosphere.
6. No ignition sources
No person carrying out work in relation to a REFRIGERATING SYSTEM which
involves exposing any pipe work 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 suciently far away from the site of installation,
repairing, removing and disposal, during which 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.
8. Checks to the refrigerating 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 refrigerant charge 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 presence of refrigerant;
marking to the equipment continues to be visible and legible, marking and signs
that are illegible shall be corrected;
05
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 purging the system;
that there is continuity of earth bonding.
refrigerating 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.
10. Sealed electrical components
11. Cabling
Check that cabling will not be subject to wear, corrosion, excessive pressure,
vibration, sharp edges or any other adverse environmental eects. The check shall
also take into account the eects of aging or continual vibration from sources such
as compressors or fans.
12. 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.
The following leak detection methods are deemed acceptable for refrigerant
systems. Electronic leak detectors may be used to detect refrigerant leaks but, in the
case of FLAMMABLE REFRIGERANTS, the sensitivity 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 used. 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 also 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.
NOTE Examples of leak detection fluids are
- bubble method,
- fluorescent method agents.
If a leak is suspected, all naked flames shall be removed/extinguished.
If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall
be recovered from the system, or isolated (by means of shut o valves) in a part of
the system remote from the leak. See the following instructions of removal of
refrigerant.
Sealed electrical components shall not be repaired.
06
13. Refrigerant removal and circuit evacuation
When breaking into the refrigerant circuit to make repairs - or for any other purpose
conventional procedures shall be used. However, for flammable refrigerants it is
important that best practice be followed, since flammability is a consideration.
The following procedure shall be adhered to:
safely remove refrigerant following local and national regulations;
evacuate;
purge the circuit with inert gas (optional for A2L);
evacuate (optional for A2L);
continuously flush or purge with inert gas when using flame to open circuit; and
open the circuit
The refrigerant charge shall be recovered into the correct recovery cylinders. The
manufacturer shall specify the inert gases that can be used. Compressed air or
oxygen shall not be used for purging refrigerant systems.
NOTE An example of an inert gas is dry nitrogen.
Purging of the refrigerant circuit shall be achieved by breaking the vacuum in the
system with inert gas 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. The system shall be vented
down to atmospheric pressure to enable work to take place.
Ensure that the outlet of the vacuum pump is not close to any potential ignition
sources and that ventilation is available.
14. Charging procedures
In addition to conventional charging procedures, the following requirements shall
be followed:
Ensure that contamination of dierent refrigerants does not occur when using
charging equipment. Hoses or lines shall be as short as possible to minimise the
amount of refrigerant contained in them.
Cylinders shall be kept in an appropriate position according to the instructions.
Ensure that the refrigerating system is earthed prior to charging the system with
refrigerant.
Label the system when charging is complete (if not already labelled).
Extreme care shall be taken not to overfill the refrigerating system.
Prior to recharging the system, it shall be pressure-tested with the appropriate
purging gas. 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.
15. 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 requiredprior to re-use of
recovered 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.
07
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 instructions.
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 cylinders and the equipment are removed from site promptly and all
isolation valves on the equipment are closed o.
k) Recovered refrigerant shall not be charged into another refrigerating system
unless it has been cleaned and checked.
16. Labelling
Equipment shall be labelled stating that it has been de-commissioned and emptied
of refrigerant. The label shall be dated and signed. For appliances containing
flammable refrigerants, ensure that there are labels on the equipment
stating the equipment contains flammable refrigerant.
17. Recovery
When removing refrigerant from a system, either for servicing or decommissioning,
it is required to follow good practice so that all refrigerants are removed safely.
When transferring refrigerant into cylinders, ensure that only appropriate refrigerant
recovery cylinders are employed. Ensure that the correct number of cylinders for
holding the total system charge is 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-o 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
the flammable refrigerant. Consult manufacturer if in doubt. In addition, 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.
The recovered refrigerant shall be processed according to local legislation in the
correct recovery cylinder, 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 compressor body shall not be heated by an
open flame or other ignition sources to accelerate this process. Draining of oil from
a system shall be carried out safely
