INTRODUCTION
Congratulations on choosing a new
Braemar cooler for your home.
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 on the
last page.
Keep these instructions in a safe
place for future reference.
This appliance is not intended for use by
persons (including children) with reduced
physical, sensory or mental capabilities,
or lack of experience and knowledge,
unless they have been given supervision
or instruction concerning use of the
appliance by a person responsible for
their safety.
Children should be supervised to ensure
that they do not play with the appliance.
SEELEY INTERNATIONAL – OWNER’S MANUAL
EFFECTIVE COOLING
To provide efficient cooling or
ventilation the building must have
sufficient exhaust openings to
outdoors in the form of doors,
windows or other vents. To assist air
circulation, open windows or doors
that are furthest from the outlet vent in
each room. In every room that has an
outlet vent, provide an exhaust
opening about 2 or 2.5 times the vent
size of the room. Where the design of
the building prevents adequate
exhaust, consideration should be
given to the provision of mechanical
extraction such as an exhaust fan.
Important Notes!
In areas where temperatures can
cause water supply pipes to freeze, a
drain down facility should be provided
during the installation.
This drain down facility must be
activated prior to freezing conditions,
to avoid possible damage to the
cooler components.

Two Speed and Variable Speed Units.
Your evaporative air conditioner has control
switches to provide for the benefits of fresh
air ventilation and cooling at high and low
air flows. There are two types of control
switches available: Two Speed (Fig. 1) and
Variable Speed (Fig. 2).
Your control panel offers independent
control for the fan and cooling functions.
Using Your Air Cooler
UNIT AREA (m )
Evaporative air coolers provide very
effective cooling by drawing outside air
through filter pads saturated with water.
This water washes the air and cools it by
the process of evaporation. There are a
number of operating techniques and
circumstances of which you should be
aware to get the best performance from
your evaporative air cooler.
To provide effective cooling or ventilation,
the air cooler must be operated with
sufficient openings to exhaust the air. For
example: windows, doors or ducts. The
location of the opening(s) will determine
the pattern of cool air flow. The following
are the minimum opening sizes required
in square metres:
EA90 0.4
EA120 0.6
EA 150 0.8
In light wind conditions more cooling can
be obtained by opening additional
windows and doors. In windy conditions
close openings facing the wind.
Generally, openings opposite the supply
vents are best. Some experimentation will
soon show the arrangement most suited
to your requirements. For a multiple outlet
system, this is generally 1 (one) window
opened 100 to 150 mm per outlet.
For a short time, when operating with new
filter pads, you may detect an odour like
"wet timber”. This is the filter material
becoming conditioned to use.
In many areas the water supply is quite
hard. When this water is evaporated
through the filter pads, the hardness is
deposited as a scale on the pad. To
reduce this scale build-up and to retain
efficient filter pads a small amount of
water is bled from the system.
The continuous drain of small amounts of
water ensures that fresh water is added to
dilute any build-up of scale or salts. The
bleed rate for your air conditioner will
depend on local operating conditions and
will be adjusted during installation.

To Start the Air Conditioner
To Stop the Air Conditioner
(1) Switch the COOL control on.
(2) Turn on the AIR (fan) control and using
the SPEED switch (HI/LO switch or Variable
knob), select the fan speed you require.
When ventilation only is required (air flow
with no cooling) turn the COOL switch off,
and select the fan speed to provide the air
flow you require.
Switch the COOL control off, then switch the
AIR control off.

Replace filter pad frames. Ensure they are
the correct way up.
If water flow appears low, there may be a
problem with foreign material clogging the
pump or pump strainer. To correct, remove
pump, dismantle base, clean and re-
assemble.
Post-season Maintenance

Turn off the power supply to the cooler.
Remove pad frames
Turn off the isolating switch inside the
cooler.
Remove pad frames. Clean them by
hosing them with clean water, but do not
use excess pressure because you might
create holes in the pad media.
Remove and clean the special water
"spreader" plates located under each edge
of the top panel. Do not disconnect from
water hose. When replacing them, check
underneath to see that the spreaders are
correctly located in the notches under the
top panel.
Drain all the water form the cooler by
removing the overflow or overflow bleed
funnel. Do NOT put it back until next
season. Do not lose the O-ring seal.
Disconnect the water supply pipe from the
tank. Make sure no water is left in the float
valve.
Clean the bottom tank thoroughly.
Replace pads frames.
Cover the cooler for winter if desired.
All units can benefit from routine
preventative maintenance. This may be
required more frequently if you are
operating under harsh conditions.
To perform Preventative Maintenance,
follow the instructions for ‘Pre-Season
Maintenance’at regular intervals.
In some areas and for some commercial
installations local regulations have specific
requirements for the maintenance of
evaporative air conditioning systems.
Generally these involve regular cleaning and
maintenance at (3) monthly intervals or more
frequently if necessary.

Check Your Local Regulations:

Maintenance
To ensure that your air cooler continues to
provide reliable service for many years, it
requires some routine maintenance. There
are two forms of maintenance:
(1) pre and post season maintenance, and
(2) preventative maintenance.
Turn off the water supply.
Turn off the power supply.
Remove the filter pad frames. Insert a
screwdriver into the slots at the bottom of
the pad frames and lever upwards. Pull
the bottom of the pad frames away from
the unit, then lower the frames out of the
cabinet (Fig. 3).
Turn off the isolating switch.
Hose both sides of the filter pads
CAREFULLY
. Ensure that the wood
wool pad material is evenly distributed,
especially make sure that there is no gaps
or holes at the TOP of PADS.
Pre-season Maintenance
Do not replace this item until
next season. Do not lose the "O" ring
seal.

removing the overflow or overflow bleed
funnel.
Check pulleys for wear and correct
alignment.
Check "V" belt for wear.
Thoroughly clean and dry the bottom of
the water tank.
