nes.
Only qualied and licensed technicians should install this
appliance, failing which the warranty on the appliance will be
void.
INSTALLER AND MAINTENANCE CONTRACTORS
A risk assessment is an essential element that should be
conducted before the commencement of work, to identify
and eliminate the risk of falls or to minimize these risks by
implementing control measures.
BEFORE YOU START
RISK ASSESSMENT
A risk assessment of all hazardous tasks is required before
commencing any work, and may be required under legislation.
There is no need for this to be a complicated process, it just is
a matter of looking at the job to be done and considering what
action(s) are necessary so the person doing the job does not
injure themselves.
This should be considered in terms of:
• What are the chances of an incident happening?
• What could the possible consequence be?
• What can you do to reduce, or better still, completely get rid of
the risk?
SOME POINTS TO CONSIDER:
• What is the best and safest access to the roof and working
areas?
• If a worker is alone, who knows they are there and if they get
into difculty, how can they summon help? (Call someone on
the ground? Mobile phone? etc.)
• What condition is the roof in? Should the trusses, underside or
surface be checked?
• Does the worker have appropriate foot wear?
• Are all power cables/extension leads safe and appropriately
rated?
• Are all ladders, tools and equipment suitable in good
condition?
• Where ladders are to be used, is there a rm, stable base for
them to stand on? Can they be tied or secured in some way
at the top? Is the top of the ladder clear of electricity supply
cables?
• Is there a roof anchor to attach a harness and lanyard to? If
so, instruction should be issued for the use of an approved
harness or only suitably trained people used.
• Are all tools and materials being used, prevented from slipping
and falling onto a person at ground level? Is the area below the
work area suitably protected to prevent persons walking in this
area?
• Does the work schedule take into account weather conditions,
allowing for work to be suspended in high winds, thunder
storms/lightning or other types of weather giving wet, slippery
surfaces?
• Is there an on-going safety check system of harnesses, ropes,
ladders and access/lifting equipment and where they exist on
roofs, anchor points before the commencement of work?
• Is there a system which prevents employees from working
on roofs if they are unwell or under the inuence of drugs or
alcohol?
• Are there any special conditions i.e. Excessive roof pitch,
limited ground area, fragile roof, electrical power lines?
This Invertair™ True Inverter Add-On Cooling unit is to be
installed indoor in the roof space and shall only be performed
by suitably trained and qualied personnel, in accordance with
local and national wiring rules.

MOST COMMON CAUSES OF POOR COOLING PERFORMANCE
Issue Cause & Description Page No.
Neglecting to use the Braemar
transitions for the DGH and/or
AOC
The Braemar transitions are specically designed to
ensure the maximum amount of air is available through
the compact TQ/TQM extra air series, and the correct
amount of air is distributed evenly through the cooling coil,
maximising efciency and performance.
8 - 10
Duct sensor positions
The duct sensor measures the air temperature in the duct
for both heating and cooling. This measurement is used to
control the gas burner rate during heating, and, as a low
temperature protection in cooling to prevent the indoor coil
from freezing.
8 - 9
Ductwork
Incorrectly sized or poorly designed duct can have a
disastrous effect on the cooling and heating performance.
Whilst it is best to keep duct runs as short as possible, it is
also advisable to have at least 3m of duct connected to any
grille or diffuser. However, if longs runs are unavoidable,
please ensure to upsize them accordingly.
Ensure the duct between the DGH and the Cooling coil are
as straight and short as possible.
8 - 10
Airow
The air is what carries the cooling and/or heating to
any area that is being conditioned. Without the correct
amount of air to any area, that area will suffer from under
conditioning.
Please ensure ductwork is designed to carry the required
amount of air for proper cooling and heating.
The fan speed has been selected to suit that amount of air
for that area. If zoned, the zoning is adjusted and checked
to ensure it is commissioned correctly.
8 - 10
Return Air Position
If the return air is located outside of the conditioned
area, the system will need to run longer to provide the
required amount of heating or cooling. This is due to the air
temperature of the non-conditioned area being higher (in
cooling) or lower (in heating) and the equipment needing to
provide more energy to achieve the result.
Refer TQ/TQM
Installation Manual
Thermostat Position
The position of the thermostat will dictate how satised
the user will be. It is at this point where the temperature
is measured and if the thermostat is not in the conditioned
space, there is a chance the conditioned space will always
be at a different temperature to that set on the thermostat.
Refer TQ/TQM
Installation Manual
Outdoor unit
Check clearances, x the unit in position, use rubber feet
as supplied. Check installation position does not breech
maximum or minimum eld installed pipe lengths.
Check the refrigerant charge matches the eld installed
pipe length.
Ensure the pipe work is installed as required, including use
of oil traps if required.
11 - 13
Electrical
Ensure correct cable and circuit breaker are used. Power
cable sizes are recommended only; AS/NZS 3000 and all
local, state and national codes must be adhered to.

*Refer locations A, B, C page 7 - Duct connection sizes do not dictate the required duct size.
*To calculate unknown dimension, divide the “Min return air lter size” by an available dimension. For example, you are installing the
SACV16D1S and you have a clearance of 450mm between studs, Min return air lter size is 0.58m², divide this by 0.45m and the
required length/height is 1.28m.
FLEXIBLE DUCTWORK CONNECTIONS
• It is important that all ductwork be tted securely and with airtight connection.
• Use the supplied square to round transitions for proper and even air ow through the heater. It is strongly recommended to use inlet
and outlet transitions for the Indoor Coil, as supplied.
• For exible duct to transition, unit or outlets, provide a mechanical connection using strapping or banding in addition to duct tape
for air seal. Do not rely on tape only.
• Ductwork should be adequately sized to suit the heater and installation to prevent excessive back pressure.
• Duct run > 6m, increase the full length of the duct run and spigot diameter by 50mm
• Duct run > 9m, increase the full length of the run and spigot by 100mm.
• Ductwork should be adequately supported and free from air leaks.

OUTDOOR CLEARANCES
• Bends in exible ductwork should be as smooth as possible and with a minimum radii of 2 duct diameters.
• Duct should be at least R1 insulated.
• All exible duct should be extended and trimmed to length. If a 6m length is compressed to 5m instead of trimming to length. A
doubling of the duct resistance is created.
• The return air duct should be a minimum of 3m and include one change of direction, to minimise noise transfer from the heater
fan.
• For servicing, a minimum clearance of 600mm must be provided in front of the access panel side of the unit for its entire length.
Important Notes:
1. Ensure that a minimum of 2 1/2 times the duct diameter of straight ductwork is installed, immediately downstream of the Indoor
unit before any divergence or branch-take offs.
2. Fill and test drain before running the system.
Air deectors allow a reduction in the clearance "d" and they can be purchased from Seeley International, refer to the Technical
Specication table on page 26. Please contact Seeley International for further advice.

Location considerations:
• Most importantly, do not install the Outdoor unit where there is a possibility it will cause a noise complaint from neighbours.
Be mindful of the environment. Installers must comply with noise regulations and operating sound levels conform to local
requirements.
• Allow sufcient clearances for maintenance around the unit. (Refer ILL1994-A).
• Be well ventilated, so that the unit can draw and distribute sufcient air.
• Be capable of bearing the weight of the Outdoor unit whilst also isolating noise and vibration. See the technical section of this
booklet for weights and dimensions.
• Use suitable rubber/wafe vibration isolators under mounting feet
• Fix unit in position to ensure it is kept upright
• Wherever possible protect the unit from direct sunlight.
• When installing by the seaside remember to make allowances to have the unit washed down to protect against the salt spray.
• Allow for drainage of rainwater.
• Not discharge air towards the prevailing wind. This may stall the condenser fan.
• Ensure air discharge and operating sound levels conform to local requirements.
• Not be susceptible to dust or oil mist.
• Ensure intake air temperature is no higher than ambient temperature. (Max. 48°C)
• Allow proximity to Indoor Coil – Minimum 3m, Maximum 50m pipe length (Refer Refrigerant Pipe-Work section page 13).

SEELEY INTERNATIONAL - INSTALLATION MANUAL |13
REFRIGERANT PIPE-WORK
WARNING! Indoor coil is pressurised with dry nitrogen, release pressure by depressing red button on indoor pipe connection cap.
If no pressure is present, coil may be damaged, please pressure test before installing.
Pipe-work must be installed in a manner which prevents drainage of liquid into the compressor, and ensures adequate oil return.
Pipes should be at least 3m in length, incorporating at least two direction changes. This will reduce transmission between Indoor and
Outdoor units.
Pipe-work is to be installed according to the Current Code of Good Practice for Refrigeration and Air-conditioning.
• Select pipe-work size from Table.
• Both interconnection lines must be individually insulated (minimum 10mm thickness).
• Do not allow moisture, dust or other foreign particles to enter the pipe-work.
• Only use refrigeration grade copper tubing, suitable for R410A and to Australian Standards.
• Installed pipe-work must be pressure tested to a minimum of 2,000 KPa for at least 1 hour using dry nitrogen
• Pipe work must not be buried underneath the ground.
VERTICAL/HORIZONTAL PIPE-WORK
Maximum vertical rise is 15m (for SCHV-10),
30m (for SCHV12-16), with oil bends every 6m.
Maximum Total length of pipe-work must not exceed 50m.
BRAZING
If brazing of pipe-work is required, dry nitrogen must be used to purge the pipe-work during welding. When brazing close to the are
nuts, a wet cloth must be used to protect the valves.
FLARING
All ares must be done with a quality aring tool, suitable for R410A and refrigeration ares.
PIPE-WORK
• Select copper pipes for gas and liquid as specied for the system (refer the pipe table below).
• For dust and moisture protection, before assembly of the pipe and its insulation, both ends of the pipe must be covered.
• Avoid pipe bending as much as possible; if it is necessary to bend, the bending radius must be more than 4cm.

Pressurise the indoor unit & pipe work again with dry nitrogen and check for any joint leaks by pressurising the system to 2,000 KPa
and holding for at least an hour. Repair as necessary, but ensure the system under repair is not under pressure prior to brazing.
With the Indoor unit pressure again released, evacuate the pipe work and indoor coil to a vacuum pressure of 500 microns (65Pa)
minimum. Hold Vacuum for at least 15 minutes.
NOTE: to ensure an accurate vacuum reading, we recommend to place the vacuum gauge as far from the vacuum pump as possible.
Disconnect the vacuum pump whilst retaining the system vacuum.
Open the liquid line valve fully and then suction line valve and hold for 15 minutes.

Braemar InvertairTM add on cooling units have a built in secondary (safe) tray. The drainage connection for this secondary tray
should be discharged in a visible location, not to cause nuisance, whilst complying with all state, local and national regulations.
Always install a “P” trap as close as possible to the primary tray connection point. The drain for the primary tray must be
terminated in accordance with all state, local and national regulations.
CONDENSATE DRAIN PIPE INSTALLATION
1. Rigid UPVC suitable for installations located externally (solar resistant) should be used.
2. Install pipe supports as required to prevent sagging, at no more than 1.5m intervals.
3. Some installation sites may require the drain to be insulated, these can be areas where high humidity is experienced. (Fig. 11)
4. Ensure the ‘P’ trap has a water seal depth of 50mm and the trap outlet is 50mm below the primary drain outlet
5. Fill the trap with water and check for fall (1:60 minimum)
