IMPORTANT
As with any product that has moving parts or is subject to wear and tear, it is VERY IMPORTANT
that you maintain the cooler and have it regularly serviced. It is a condition of warranty cover for
your cooler that you comply with all of the maintenance and service requirements set out in the
Owner’s Manual. Compliance with these requirements will prolong the life of your cooler. Further,
it is also a condition of warranty cover that each item in the Maintenance Schedule in the
Owner’s Manual is performed with the frequency indicated, by a qualified, licensed technician,
and that the Maintenance Schedule is properly filled out (ie names, signature, date, and action
taken) when the item is completed. ANY FAILURE TO CARRY OUT THE REQUIRED MAINTE-
NANCE AND SERVICING REQUIREMENTS, AND ANY FAILURE TO PROPERLY FILL OUT
THE MAINTENANCE SCHEDULE, WILL VOID YOUR WARRANTY.

EMPLOYER AND EMPLOYEE RESPONSIBILITIES
The installation and maintenance of evaporative air conditioning units, particularly at height, has the potential to
create Occupational Health and Safety issues for those involved. Installers are advised to ensure they are familiar
with relevant State and Federal legislation, such as Acts, Regulations, approved Codes of Practice and Australian
Standards, which offer practical guidance on these health and safety issues. Compliance with these regulations
will require appropriate work practices, equipment, training and qualification of workers.
Seeley International provides the following information as
a guide to contractors and employees to assist in minimising risk.
Risk Assessment:
A risk assessment of all hazardous tasks is required under legislation. A risk assessment is an essential element
that should be conducted before the commencement of work, to identify and eliminate the risk of falls and other
risks, or to minimise these risks by implementing control measures. This does not need to be a complicated
process - it is a matter of assessing 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 occurring?
- What could the possible consequences be?
- What can be done to reduce, or better still, eliminate the risk?
Some points to consider when working on or in a roof:
- Check State regulations regarding working at height.
- What is the best and safest access to the roof and working areas?
- What condition is the roof in? Should the roof structure and surface be checked?
- Does the worker have appropriate footwear?
- Are all power cables/extension leads safe and appropriately rated?
Are all ladders, tools and equipment suitable and in good condition?
Where ladders are to be used, is there a firm, stable base for them to stand on? Can they be tied or secured
in some way at the top?
- 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 people entering 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 or in roofs if they are unwell or under the
influence of drugs or alcohol?
- Are there any special conditions to consider i.e. excessive roof pitch, limited ground area, fragile roof,
electrical power lines?
- Use the appropriate lifting equipment.

Introduction.
All Braemar air conditioners are run and electrically tested at the factory.
Subject to normal handling during storage, transit, installation and operation, they will provide
years of economical air conditioning with the minimum of service and maintenance.
All Braemar air conditioners are designed for a range of installations and are readily adaptable to
the following applications.
a. Through wall or window mounting for direct discharge through the appropriate air
diffusion equipment
b. Wall mounting for plenum chamber diffusion.
c. Roof (all models), ground or wall mounting for connection of multiple outlet duct systems.
d. Roof (all models), ground or wall mounting for connection to a duct system for central
plenum air diffusion.
Location of Air Conditioner.
To ensure only fresh air flows through the filter pads. locate the cooler away from chimneys,
exhaust/extractor flues, heater flue pipes and sewer vents.
Check your local building code for the minimum distances in your area.
Allow adequate access to and around the cooler for maintenance. Provision must be made for
access to electricity, water supply and drains
Thoroughly seal all roof penetrations, this will ensure storm water cannot enter the building as a
result of the installation
Important!

 Connection to the Electricity Supply
It is a requirement of Seeley International that all coolers be wired with a dedicated circuit to the
distribution board adhering to Local and National wiring standards. Ensure that the power supply
corresponds to the rating indicated on the serial plate.
RPA coolers ( RPA400 - 900 ) have a 25mm diameter knockout hole at the top and bottom of the
front panel, use one of these holes for the conduit entry. Wire the unit in accordance with the
wiring diagram supplied and the local supply regulations.
RPA coolers ( 1000 - 1800 ) have a separate mains isolator located on a corner pillar. Wire the
mains power to the isolator.
 Mounting the Control Switch - Mount the control switch in the most desirable location.
 Two Speed Single & Three Phase Units
Controls for two speed air conditioners are 240 Volt Clipsal switch plate pattern.
No adjustment of minimum or maximum speed is necessary.
Control circuit wiring is via a 240V 5 wire system.
Wire the unit in accordance with the wiring diagram supplied and the local supply regulations.
 Mains Water connection is made to the float valve fitted in the reservoir. The mains
water supply to and inside the unit should be made with the appropriate copper pipe and
fittings. A stopcock must be fitted outside the unit.
The float valve must be set to maintain the reservoir water level about 10 mm below the
overflow level.
An overflow stand pipe is supplied with the unit and must be fitted to the hole
provided in the water reservoir. RPA400 - 1800 have a 40 mm drain/overflow supplied as
standard.
 Drain Valves
When fitting drain valves, other than the Seeley type, the overflow assembly must not be
removed. Fit the drain valve in a separate location in a new hole.
When fitting the Seeley Drain Valve, use the existing overflow assembly hole.
NOTE: Flush the mains water supply before connection to the unit
to remove any foreign matter which may foul the float valve seat.
Ensure that the drain hole in the reservoir and any penetrations
through the roof are adequately sealed with an approved sealant.

RPA INDUSTRIAL AIR CONDITIONERS
Models RPA400 - 900 are fitted with a variable pitch pulley so that the full potential of the motor
can be utilised. The pulley is set at the factory to approximate the full motor load with the unit at
free delivery. When installed and operating against system resistance, (with doors and windows
open) adjustment may be made to the pulley in order that all the available power is utilised.
Models RPA1000 - RPA1300 are supplied with variable pitch pulleys. Fixed pulleys are fitted to
the RPA1400 - RPA1800.
 Method of Variable Pulley Adjustment.
1. Ensure installation is complete and that all registers are set to their maximum openings.
2. Operate the unit and allow the motor to warm up ( 10 - 15 minutes ).
3. Measure the current being drawn by the motor on high speed.
4. Compare the rated current shown on the rating plate, to the measured current. If the current is
significantly above or below the rated current, pulley adjustment may be made as follows.
5. Isolate unit and remove the “ V “ belt/s. Loosen the grub screws in the flange of the pulley.
Screw pulley flange in to increase the blower speed and amperage, and screw it out to
decrease blower speed and amperage.
Re-tighten the grub screws in the flange evenly.
6. Adjust the pulley as shown in figure below.
7. It will be necessary to adjust the belt tension by using the jacking screws after any pulley
adjustment has been made.
8. A new drive can be tightened initially 50% more than normal to allow for the drop in tension
during run-in.
 If turning pulley counter clockwise to reduce
blower speed, ensure that the V section is not
opened far enough to allow the belt to ride on
the threaded part of pulley, as this will cause
damage to the belt.
 Too great a belt tension will increase
motor load, and shorten belt and bearing
life.
Too loose a belt will cause belt slippage
and excessive belt and pulley wear.

To reduce the accumulation of salts and minerals in the recirculated water it is essential to bleed a
certain amount of water to waste. Increased flow of make up water reduces the salt content.
The bleed rate will vary with the water supply quality, but should initially be set to the minimum
recommended bleed rates as set out in the chart below. The bleed line from the flow and bleed
controller in the pump delivery line, inside the unit , must be suspended through the overflow
stand pipe, or into the side of the optional drain valve. Connect suitable pipe work to bottom
thread of the drain bush so that water drains directly to waste.

RPA450 12 RPA700 18 RPA1200 31 RPA1500 39
RPA500 13 RPA900 24 RPA1300 34
 Location of Bleed Control.
The bleed control tap is located externally on a corner pillar.
Adjustment to the bleed rate is made by turning the black/red tap control to the desired setting.
Check the bleed rate by running into a graduated container for a set time, say 10 minutes.
Build up of salt deposits in the pads or the tank indicates that the bleed rate is inadequate.
Increase the rate where necessary.
 Check the Full Load Amps
After any adjustments to belt tension, the maximum full load current must be checked
to ensure it is within the rating specified on the serial plate. If the amps are not within
rating, make adjustments to the motor pulley as described in this section. Only units
with a variable pitch pulley can be adjusted, other units will need to have the
installation checked.
Check that the full load current on high and low speed is within the motor rating.

To provide efficient cooling or ventilation your air conditioner must be operated with sufficient
exhaust openings in the form of doors, windows, or other vents.
One square metre of open area is the minimum requirement for every 3000 m3/hr (830 l/s) of air
delivery. ( ie. a 6000 m3/hr (1660 l/s) air conditioner requires a minimum of 2 square metres of
open exhaust areas ).
For optimum cooling performance, windows opposite the prevailing wind conditions should be
opened. The cool filtered air entering the building will flow toward the exhaust openings. Doors
and windows should be set according to the airflow pattern desired.
Air should never be recirculated back through the air conditioner.
When the design of the building or prevailing winds prevent effective airflow, consideration must
be given to the use of some form of exhaust extraction device.

REGULAR MAINTENANCE IS ESSENTIAL FOR MAXIMUM EFFICIENCY
To ensure that your Braemar Evaporative Air conditioner remains in first class working
condition for many years, it should be thoroughly serviced four (4) times a year. Service
schedules should include a service at the end of the summer season and prior to the
commencement of the next summer season.
Service & Maintenance
11. Lubrication - All models. 
Bearings on electric motors and water pumps are sealed for life and do not require
lubrication. The same applies to the fan shaft bearings on the RPA400-RPA900.
RPA1000 - RPA1500 fan shafts are fitted with plumber blocks with grease nipples, lubricate
at regular intervals, depending on frequency of use.
. Health Regulations. 
Please note that some State Regulations require that Evaporative Air Conditioners
used for Commercial purposes must be serviced at Three ( 3 ) Monthly Intervals.
Owners of Commercial Air Conditioners should contact the Health Authority in their State for
servicing guidelines.
