determined by local regulations.
6.Information on servicing
1)Checks to the area
Prior to beginning work on systems containing ammable 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.
2)Work procedure
Work shall be undertaken under a controlled procedure so as to minimise the risk of a
ammable gas or vapour being present while the work is being performed.
3)General work area
All maintenance sta and others working in the local area shall be instructed on the
nature of work being carried out. Work in conned spaces shall be avoided. The area
around the workspace shall be sectioned o. Ensure that the conditions within the area
have been made safe by control of ammable 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 ammable atmospheres. Ensure
that the leak detection equipment being used is suitable for use with ammable
refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
5)Presence of re extinguisher
If any hot work is to be conducted on the
refrigeration equipment or any associated parts,
appropriate re extinguishing equipment shall be available to hand. Have a dry powder
or CO2 re extinguisher adjacent to the charging area.
6)No ignition sources
No person carrying out work in relatio
n to a refrigeration system which involves exposing
any pipe work that contains or has contained
ammable refrigerant shall use any sources
of ignition in such a manner that it may lead to the risk of re 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 ammable
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
ammable hazards or ignition risks. No Smoking signs shall be displayed.
Page 8
WARNINGS (for using R290/R32 refrigerant only)
7)ventilated area
Ensure that the area is in the open or that it is 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.
8)Checks to the refrigeration equipment
Where electrical components are being changed, they shall be t for the purpose and to
the correct specication. 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 ammable
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 circuit shall be checked for
the presence of refrigerant;
Marking to the equipment continues to be visible and legible. Markings 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, an
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.
7.Repairs to sealed components
1)During repairs to sealed components, all electrical supplies shall be disconnected from
the equipment 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.
2)P
articular attention shall be paid to the following to ensure that by working on electrical
components, the casing is not altered in such a way that the level of protection is aected.
This shall include damage to cables, excessive number of connections, terminals not made
to original specication, damage to seals, incorrect tting of glands, etc.
Ensure that apparatus is mounted securely.
Page 9
WARNINGS (for using R290/R32 refrigerant only)
Page 10
Ensure that seals or sealing materials have not degraded such that they no longer serve
the purpose of preventing the ingress of ammable atmospheres. Replacement parts
shall be in accordance with the manufacturer's specications.
NOTE: The use of silicon sealant may inhibit the eectiveness of some types of leak
detection equipment. Intrinsically safe components do not have to be isolated prior to
working on them.
8.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. Intrinsically safe components are the only types that can be worked on
while live in the presence of a ammable atmosphere. The test apparatus shall be at the
correct rating.Replace components only with parts specied by the manufacturer. Other
parts may result in the ignition of refrigerant in the atmosphere from a leak.
9.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.
10.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 ame)
shall not be used.
11.Leak detection methods
The following leak detection methods are deemed acceptable for systems containing
ammable refrigerants. Electronic leak detectors shall be used to detect ammable
refrigerants, but 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 conrmed. Leak detection uids 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
ames 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. Oxygen free nitrogen (OFN)
shall then be purged through the system both before and during the brazing process.
12.Removal and evacuation
When breaking into the refrigerant circuit to make repairs or for any other purpose
conventional procedures shall be used. However, it is important that best practice is
followed since ammability is a consideration. Opening of the refrigeration systems shall
not be done by brazing. The following procedure shall be adhered to:
Remove refrigerant;
Purge the circuit with inert gas;
Evacuate;
Purge again with inert gas;
Page 11
WARNINGS (for using R290/R32 refrigerant only)
Open the circuit by cutting or brazing.
The refrigerant charge shall be recovered into the correct recovery cylinders. The system
shall be ushed with OFN to render the unit safe. This process may need to be repeated
several times. Compressed 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 ll until the working pressure is achieved, then venting to atmosphere, and
nally pulling down to a vacuum. This process shall be repeated until no refrigerant is
within the system. When the nal OFN charge is used, the system shall be vented down
to atmospheric pressure to enable 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 close to any ignition sources and there
is ventilation available.
13.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 upright.
E
nsure 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 overll 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.
14.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 protective 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.
h)Do not overll cylinders. (No more than 80 % volume liquid charge).
i)Do not exceed the maximum working pressure of the cylinder, even temporarily.
Page12
WARNINGS (for using R290/R32 refrigerant only)
j)When the cylinders have been lled 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 refrigeration system unless it
has been cleaned and checked.
15.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 ammable refrigerant.
16.Recovery
When removing refrigerant from a system, either for servicing or decommissioning, it is
recommended good practice 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
ammable refrigerants.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. 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 refrigerant release. Consult
manufacturer if in doubt.
The recovered refrigerant shall be returned to the refrigerant supplier 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 ammable refrigerant does not remain within the lubricant. The evacuation
process shall be carried out prior to returning 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.

B. Thru-The-Wall Installation
NOTE:
Consult local building codes prior to
installation or a qualied carpenter.
NOTE: If wall thickness is 8-1/2 " or more, add
aluminum ashing over bottom of frame opening
to assure no water can enter area between inner
and outer wall.
The air conditioner has a slide-out chassis, so
that it can be installed through an outside wall
as specied below:
Max. Wall thickness: 12" or 10"
IMPORTANT: Side louvers must never be blocked.
NOTE: All parts needed for Thru-The-Wall
Installation are provided, except a wood frame,
shims, and 10 wood screws(#10-1" long minimum).
Select a wall surface that:
1. does not support major structural loads such
as the frame construction at ends of windows,
and under truss-bearing points, etc.
2. does not have plumbing or wiring inside.
3. is near existing electrical outlets or where
another outlet can be installed.
4.is not blocked to the area to be cooled.
5. allows unblocked airow from rear sides and
end(outside) of installed air conditioner.
1. Prepare wall in frame construction (including
brick and stucco veneer). Working from inside
the room, nd wall stud nearest the center of
area where air conditioner will be installed (by
sounding wall or by magnetically nding nails).
2. Cut or knock out a hole on each side of center
stud.
3. Measure between inside edges of every other
stud as shown in Fig.1.
4. Build a wooden frame with the INSIDE dimensions
of your model listed above. (Remember to measure
twice). Frame depth should be the same as wall
thickness. Fill in the space from the opening to the
studs with wood spacers,as shown.
5. Nail frame to spacers to spacers with front ush
with drywall.
Carefully measure and cut an opening with the
following dimensions depending on your model.
See Fig.1 and Fig.2.

Prepare and Install Cabinet
1. Slide chass is from cabinet. Refer back to
Step one of Window Mounting.
2. Place cabinet into opening with bottom
rail resting rmly on bottom board of wooden
frame.
3. Position cabinet to achieve proper slope for
water removal.(See Fig.5 below.)
4. Secure bottom rail to wood frame with two
large wood screws 1"(2.5cm) long using the two
holes in the bottom of the channel resting on
frame.(See Fig.6 ).
5. Screw or nail cabinet wooden frame using shims
if frame is oversized to eliminate distortion. See
Fig.8.Remember to maintain proper slope as
described in Step 3.
6. Install chassis into cabinet by followings all
steps in Steps 8 of Window Mounting.
OPTIONAL: Caulking and installation of trim on
nterior wall may be done. You can buy wood
from your local lumber or hardware supply. On
the outside, caulk openings around top and
sides of cabinet, and all sides of wood sleeve to
the opening.
NOTE: See Step 5, Item 3 of Window Mounting
Instructions for bottom rail seal location.
1. Cut or build a wall opening in the masonry
wall similar to the frame construction (refer to
Step 2 of Thru-the-wall Installation for a wall
thickness greater than 8-1/2 " ).
2. Secure cabinet in place using masonry nails,
or the right masonry anchor screws. (Another
way to secure cabinet is to build a frame in the
masonry wall such as the one shown in Fig. 3
of Step 2 Prepare Wall. Securely anchor frame
to masonry wall. This way gives very good louver
clearance on either side of cabinet.)
3. Install a lintel to support masonry wall above
cabinet. Existing holes in cabinet can be used
and/or additions holes can be drilled to fasten
cabinet at various positions. Be sure that side
louver clearance is in accordance with Step 1
Select Wall Location.
4. Install exterior cabinet support brackets as
shown in Step 2 of Thru-the-wall installation.
Caulk or ash if needed, to provide a weather-
tight seal around top and sides of cabinet.
5. To complete installation, apply wood trim
molding around room side projection of cabinet.
Refer to Step 5 of Window Mounting for assembly
of support brackets. A wooden strip nailed to the
outside wall should be used in conjunction with sill
support angle brackets.
NOTE: Check that air conditioner is tilted
back about 1 "to 1 "(tilted about 3°to
4° downward tothe o utside). After proper
installation, condensate should not drain
from the overowdrain hole duringnormal
use,correctthe slope otherwise (Fig.14).
