SAFETY INFORMATION
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:
zWhat are the chances of an incident occurring?
zWhat could the possible consequences be?
zWhat can be done to reduce, or better still, eliminate the risk?
Some points to consider when working on or in a roof:
zCheck State regulations regarding working at height.
zWhat is the best and safest access to the roof and working areas?
zWhat condition is the roof in? Should the roof structure and surface be checked?
zDoes the worker have appropriate footwear?
zAre 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?
zIs 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
zAre 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?
zDoes 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?
zIs 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?
zIs there a system which prevents employees from working on or in roofs if they are unwell or under the
influence of drugs or alcohol?
zAre there any special conditions to consider ie. excessive roof pitch, limited ground area, fragile roof,
electrical power lines?
zUse the appropriate lifting equipment.

INTRODUCTION
Congratulations on choosing a new Braemar cooler. Your cooler is built from the highest
quality materials and engineered to provide many years of economical, trouble free cooling.
Please take a few minutes to read these instructions so you have a full understanding of
how to operate your cooler. Your installer should demonstrate the features and procedures
set out in these instructions. The installer should also provide you with a Model and Serial
Number which can be filled out in the section on the inside of the front cover.
Keep these instructions in a safe place.
All BRAEMAR air conditioners are operationally tested at the factory. Subject to normal
handling in storage and transit, correct installation and operation, they will provide years of
economical cooling with the minimum of service and maintenance. Braemar air conditioners
are designed for a range of installations and are readily adaptable to the following
applications.
a. for connection to multiple outlet duct system
b. for connection to a duct system for central air plenum diffusion.
Installation Recommendations and Procedures.
To ensure only fresh air flows through the filter pads, locate the cooler a minimum distance
away from;
a. Solid fuel type chimneys or flues - 3 metres
b. Gas Heater flues - 1.5 metres
c. Sewer or breather vent pipes - 5 metres
Remember to check your local building code for the minimum distances in your area.
Position the unit to allow access to the reservoir for plumbing fixtures and servicing.
Thoroughly seal all roof penetrations, this will ensure storm water cannot enter the building
as a result of the installation.
Effective Cooling Requirements.
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 cubic metres per
hour of air delivery. ( ie. A 6000 cubic metres per hr. 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 house will flow toward the exhaust openings.
Doors and windows should be set according to the airflow pattern desired.
Air should never be re-circulated 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.

INSTALLATION
These units have been designed
to be directly mounted on top of a
suitably sized and strengthened
metal duct. Fixing is by means of
self drilling screws or rivets
through the steel mount on the
bottom of unit to metal duct.
Models RPC250, RPC320,
RPC400 & RPC450 require a 550
x 550 square dropper.
RPC "Side and Top" discharge
units are required to be mounted
onto a level platform and must be
strong enough to support the unit
under operating and prevailing
conditions.
It is the policy of Seeley International to introduce continual product improvement. Accordingly, specifications are subject to
change without notice. Please consult with your dealer to confirm the specifications of the model selected.

bulging at the corners.
2. The aluminium straps B,C,D & E fit inside the skirt.
3. Using one of the aluminium straps, mark and drill the rivet holes.
Note - The bottom edge of the strap is intended to be level with the edge of the
opening in the cooler.
4. Fit strap (part B) using the 5 of the rivets supplied, starting from the centre and
working towards the ends.
The skirt must be tucked under the aluminium strap before riveting.
5. Fit Straps C & D before fitting strap E.

INSTALLATION
Water Supply
Bleed Control
Mains connection is made to the
float valve fitted in the reservoir.
The float valve must be set to
maintain the reservoir water level
about 10 mm below the overflow
level. (Fig. 5). The mains water
supply should be fitted with a ball
valve and connection to the unit
from the stopcock be made with
the appropriate copper pipe and
fittings.
NOTE:
Flush the mains supply before
connection to the unit to remove
any foreign matter which may foul
the valve seat. Remember to use
a Pipe Cutter to cut copper pipe.
To reduce the accumulation of salts and
minerals in the cooler when running for
long periods it is essential to bleed a
certain amount of water. 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 Bleed System (page 7). If
your water supply is of poor quality, higher
bleed off rates are necessary to ensure
reasonable pad life and cooler
performance. Place the hose from the
bleed tap into the overflow pipe. ( Fig. 6)
Connect suitable pipe work to bottom of
the overflow bush so that water drains
directly to waste. Drain plumbing must be
in accordance with local regulations

An optional Water Manager Kit, Part #
073392, can be supplied with the cooler or
at a later date if required. The water
manager, which is fully automatic, is
controlled by the CPMD electronics
combined with your Braemar wall control.
The system is designed to ensure that the
water is always fresh, maintains your cooler
in good condition and ensures optimum
cooling performance.
When the cooler is off for 72 hours, the
drain valve will open automatically and
empty water from the cooler. When the
cooler is turned on again, fan operation will
delay for a few minutes while the tank refills
and the cooling pads are saturated again.
At any time when the wall control is OFF,
you can drain the cooler by pressing and
holding Sand Tfor 1 second. The display
will show "dr" to confirm the operation has
activated.

suitably protected by fuse or circuit breaker.
Ensure that the power supply is sufficient for the
rating indicated on the serial plate. Wire the unit in
accordance with all state and local regulations.
NOTE
Mains cable must be double insulated if both
mains and control cables are run in the same
conduit. Please ensure that the hole in the
reservoir and any penetration through the roof are
adequately sealed with an approved sealant.

We recommend that you have a short test lead on hand for Coolers with a hard wired
control system. You can then take the wall control to the roof and control the cooler
from there. This will save you a lot of time. The short test looms are available from your
Seeley spare parts distributor (P/No. 831534).
Power up the cooler using the on / off switch on the Electronics control module. Test
motor and pump operation. Look at the front of the module where two light emitting
diodes (LEDs) are situated. The left LED is "Tricolour" and can glow green, red or
amber. The right LED is red only. If the LED (fig 12 item G) is double flashing,
everything is ok, this is normal operation.
The following information allows quick diagnostics at start up. For more detailed
information, consult the CPMD service guide.
¾The "Tricolour LED"
- acts as a general diagnostic indicator, and will function as follows.
Green double flash every 2 seconds indicates the control is running normally.
If it does not glow at all, then there is no power to the electronics module. (Check
isolating switch, circuit breaker, plug and socket connection), or a failure has occurred.
Red flashing indicates one or more of the following faults is present.
1 red flash indicates...... Fault code #1 - Communication failure
2 red flashes indicate...... Fault code #2 - Failure to detect water probes.
(only for coolers with Solenoid, Probes and Drain Valve).
4 red flashes indicate...... Fault code #4 - Failure to clear probes during
drain. (only for coolers with Solenoid, Probes and Drain Valve).

¾The "Red" LED
- indicates the status of the Water Manager
measurement circuit and will function as follows.
1 flash indicates....... Water
manager is operating and the measured salinity
is below the set point.
2 flashes indicate...... Water
manager is operating and the measured salinity
is above the set point.
3 flashes indicate...... The salinity
control method = Drain every 65 minutes.
4 flashes indicate...... Incorrect

INSTALLATION
Setting The Motor Current
13
Important! The motor pulley and belt
tension need to be adjusted to ensure
that the motor is running at its rated
capacity.
If the current is set to low, the cooler
will not perform to its optimum
capacity, and the motor speed control
may not work effectively.
The RPC two Speed units need to
have full load amps checked on high
and low speeds.
Before setting the current please
ensure that;
- The electronics module is fitted securely, and all leads have been connected
correctly.
- All ducting and registers are in place.
- Windows and doors in rooms are opened sufficiently, and
- All pad frames except the ones on the motor side and pulley side are in place.
1..... Run the motor at maximum speed by operating the cooler with the wall control
set to MANUAL mode, maximum fan speed, ventilation only. WARNING! Ensure
that the pump is not running.
2...... Continue running the motor for ten minutes (warms up the motor) before
proceeding with the current measurement. During this period carry out general
system checks including airflow, etc.
3...... Measure the motor current with a clamp meter. Attach the clamp meter
around one of the motor cables as shown (fig 13).
Compare the measured current with the rated current located on the motor. If the
measured current is less than, or greater than the rated current, the adjustable
pulley should be altered accordingly. Refer heading Pulley Adjustment.
The measured current should be equal to, or within half an amp below that of the
rated current. It must never be more than the rated current.
Replace all covers and switch off clamp meter when adjustments are made.

B=Motor
C = Grub Screw
D = Adjustable Sheave
E = Locking Cap
F = Locking Cap Fixing Screw
All RPC units 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 fully) adjustment
may be made to the pulley in order that
all the available power is utilised.
¾Method of Pulley Adjustment
Important! Never attempt this
adjustment with the cooler operating.
Pulley adjustment is made with the
Cooler power isolated at the
Electronics Module.
1..... Remove the drive belt.
2..... To adjust the pulley; Remove the securing screw that holds the locking cap in
place. The adjustable half of the pulley is free to be adjusted by rotating it on its
thread. (fig 14)
3..... To increase the blower speed and therefore increase the motor amps, the two
halves of the pulley must be closer together, ie. turn the adjustable half clockwise
(pulley in).
4..... To decrease the blower speed and therefore decrease the motor amps, the
two halves of the pulley must be further apart, ie. turn the adjustable half of the
pulley anti-clockwise (pulley out).
5..... When an adjustment is made; Replace the locking cap, aligning the screw
hole with the nearest hole in the adjustable sheave. Lock it in place with the
securing screw. Refit the drive belt (ensure tension is correct, ie. no slipping and
not too tight, as this effects the motor current (fig 15) then check the amps
6...... Smaller adjustments should be made each time you approach the desired
setting. Refer heading Belt Tension

Note! This adjustment must be done
immediately after the motor current
adjustment has been completed.
Belt tension is important, if it is too tight
there will be excessive belt and bearing
wear. If belt tension is too loose there will
be belt slip and excessive wear,
accompanied with noise and loss of
cooler performance.
Note! Adjusting belt tension is not the
correct way to alter motor current, The
current can only be altered by adjusting
the motor pulley.
The belt tension should be adjusted so
that the maximum deflection is 15mm to
20mm when a reasonable force
(approx..... 1.5kg) is applied.
It is important to check the motor current
rating again after making any alterations
to the belt tension. This may require a
further adjustment to the motor pulley,
which may have been slipping, giving
an incorrect reading.

Motor Low Speed Setting (Variable Speed Only
16
RPC coolers fitted with the Electronics
Module and Variable Speed Wall Control,
will function across a wide speed range.
The minimum speed has been factory set,
and should not require any adjustment
under normal circumstances. However,
some adjustment may be necessary to
suit specific installations.
After you have set the motor current and
belt tension correctly, check the speed
variation of the cooler. When the control is
changed from maximum to minimum
settings, there should be an easily
recognizable difference in fan speed.
If not, check the following;
1.... That windows and doors are open.
Rule of thumb is to have 2 times the area
of the outlet grille open for exhaust in
each room.
2..... The weather damper is able to move freely (where fitted).
If the above are all correct then proceed as follows.
3..... Set the fan speed to minimum using the wall control, so that only one bar is
displayed.
5..... Turn the minimum speed adjustment knob clockwise or anti-clockwise, until
the belt is running at approximately one revolution per second (this equates to a fan
speed of approximately 600 rpm). The fan will give a burst on start up to open the
weather damper (where fitted). Switch the fan off then on again, to ensure that the
fan spins fast enough to open the weather damper and keep it open. It is important
to allow the cooler to run for a while on minimum speed, to ensure the weather
damper remains in the fully open position.
