in a BAL-12.5 to 29 area the evaporative cooler
dropper duct and ashings shall be adequately
sealed at the roof to prevent gaps greater than
3mm. The dropper duct and ashings shall be
non-combustible.
WARNING: This cooler is NOT APPROVED
for installation in any bushre zoned area/
property (BAL-12.5 to BAL-FZ).
WARNING - TO REDUCE THE RISK OF
FIRE, ELECTRIC SHOCK, OR INJURY TO
PERSONS, OBSERVE THE FOLLOWING:
a) Use this unit only in the manner intended
by the manufacturer. If you have ques-
tions, contact the manufacturer.
b) Before servicing or cleaning unit, switch
power o󰀨 at service panel and lock the

EMPLOYER AND EMPLOYEE
RESPONSIBILITIES
The installation and maintenance of evaporative
coolers at height has the potential to create Oc-
cupational Health and Safety issues for those
involved. Installers are advised to ensure they
are familiar with the relevant State and Federal
legislation, such as Acts, Regulations, approved
Codes of Practice and Australian Standards,
which o󰀨er practical guidance on these health
and safety issues. Compliance with these reg-
ulations will require appropriate work practices,
equipment, training and qualications of work-
ers.
Seeley International provides the following in-
formation as a guide to contractors and employ-
ees to assist in minimising risk whilst working at
height.

SEELEY INTERNATIONAL - INSTALLATION MANUAL 859749-A |5
IMPORTANT
As with any product that has moving parts
or is subject to wear and tear, it is VERY
IMPORTANT that you maintain your 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 this 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 Manual is
lled out (by signing and dating it in the places
indicated) when the item is completed.
Any failure to carry out the required
maintenance and servicing, and any failure to
ll out the maintenance schedule, will void your
warranty.
MAINTENANCE NOTE
IMPORTANT SAFETY INSTRUCTIONS
INSTALLER AND MAINTENANCE
CONTRACTORS - RISK ASSESSMENT
Installer and Maintenance Contractors
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 or to minimise
these risks by implementing control measures.
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 di󰀩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? (Flat sole jogger type is advisable)
• Are all power cables / extension leads
safe and appropriately rated?
• Are all ladders, tools and equipment suit-
able 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 har-
ness and lanyard to? If so, instruction
should be issued for the use of an ap-
proved 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 ac-
count 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 com-
mencement of work?
• Is there a system which prevents em-
ployees from working on roofs if they are
unwell or under the inuence of drugs or
alcohol?
• Are there any special conditions to
consider i.e. excessive roof pitch, limited
ground area, fragile roof, electrical power
lines?
OTHER IMPORTANT REQUIREMENTS
• Never force parts to t because all parts
are designed to t together easily without
undue force.
• Never drill holes in the tank of the cooler.
• Check the proposed cooler location, to
ensure that it is structurally capable of
supporting the weight of the cooler, or
provide an adequate alternate load bear-
ing structure.
• Ensure the installation complies with all
local and national regulations with re-
gards to electrical, plumbing and bushre
construction requirements.

SEELEY INTERNATIONAL - INSTALLATION MANUAL 859749-A |15
WATER SUPPLY INSTALLATION
Climate Wizard requires a permanent water supply to be
connected.
Installation of the water supply to the cooler must conform to
local plumbing rules, regulations and standards:
The following specications for water supply are required:
• Water Connections:
½” BSP (Aus/Eur), ½” NPT (USA)
male connection supplied suitable for a compression tting.
• Water Supply:
100kPa (15psi) - 800 kPa (115psi)
MAXIMUM @ 20L/min (5.3 gal/min)
• Water Supply Temperature:
40°C (105°F) MAXIMUM
• Water Supply Salinity:
100 to 1150µS/cm
Important! If the water pressure exceeds this maximum
specication then a pressure reducing valve is required and
must be supplied and tted by the installer.
The installer must provide a manual 1/4 turn ball type shut o󰀨
valve (do not use a stop cock) in the water supply line adjacent
to the cooler, subject to local plumbing regulations. This allows
the water supply to be isolated whenever work needs to be
done on the cooler.
In areas subject to freezing, the water line needs a drain
down facility.
WATER SUPPLY FILTRATION
Seeley International requires an inlet lter to be installed on
the water supply line, external to the Climate Wizard cooler
to prevent any debris from entering and damaging cooler
components.
Important! Flush the water pipe to remove any contaminants
(swarf, lings or dirt) before nal tting. Contaminants can lodge
in the solenoid, preventing it from functioning correctly.
Climate Wizard’s water management system is designed to
use water that is suitable to be classied as ‘potable’ and t for
human consumption. If alternative water (including rain water)
is to be used that contains high levels of salinity, hardness,
acidity or chemical contaminants, then additional ltration or
treatment systems should be employed to render the water
‘potable’.
WATER HAMMER
Not all installation pipeworks are the same, and some may
require additional prevention against water hammer.
If water hammer is a problem, it is the responsibility of the
Installer to t an appropriate water hammer arresting device
external to the cooler.
WATER DRAIN INSTALLATION
Climate Wizard coolers require a permanent water drain to
be connected. A built-in Drain Valve, controlled by the water
management system, releases water from the cooler when
required.
The cooler installation kit contains components to congure the
Drain Valve discharge to one of the following options;

accordance with local regulations. It is a requirement of
Seeley International - Never drain the water directly onto
the roof.

ELECTRICAL SUPPLY INSTALLATION
(AUSTRALIA, EUROPE - 3PH 380-415V)
Please Note! There are specic models for regional specic
voltages and frequencies which are not interchangeable,
as these require di󰀨ering component congurations that vary
according to the supply frequency and voltage. Specically, the
main fan motor, 3 phase lter, transformer and pump are unique
to the voltage/frequency of supply.
INSTALLATION OF THE COOLER MUST CONFORM
TO LOCAL ELECTRICAL RULES, REGULATIONS AND
STANDARDS.
It is a requirement of Seeley International that all coolers
be wired with a dedicated circuit and circuit breaker to the
distribution board, incorporating an isolation switch in the xed
wiring with all pole disconnection from the mains power in
accordance with the local wiring rules.
Specication : 380 - 415V / 50 Hz / 3 Phase with Neutral /
4.9Amps per phase
Climate Wizard requires 3-phase Neutral and Earth electrical
power. If required, mains isolation switch is to be furnished by
the contractor adjacent to the cooler - if mounting on the cooler
cabinet, take care not to puncture the water reservoir. Mains
power terminals are provided inside the electrical cabinet with
glands provided for cable entry.

When “BMS” is selected on the CONTROL screen, the Error
Status Terminal will output 24Vdc in the event of a cooler fault.
This can be used either drive a relay coil or an indicator lamp.
• Maximum Current = 3A Resistive
• Minimum Switching Capacity = 100mA
Cooler Operating Mode Input Terminals
When “BMS” is selected on the CONTROL screen, cooler
operating mode is set via the use of BMS input terminals IEC
and DEC, with the following logic;
BMS COOLER MODE IEC DEC
VENT FALSE FALSE
INDIRECT COOL ONLY TRUE FALSE
DIRECT COOL ONLY FALSE TRUE
INDIRECT & DIRECT COOL TRUE TRUE
Note: Direct Cool available for use on Supercool Models only.
Warning: The BMS Input Terminals are non-isolated dry
contacts. Do not apply an external power supply, instead use a
switch to connect the Input Terminal to the BMS GND Terminal
Fan Speed Input Terminals
When “BMS” is selected on the CONTROL screen, cooler fan
speed is set by applying an analogue 0-10Vdc signal to the Fan
Speed Input terminal, with the following logic;
BMS FAN SPEED MINIMUM VOLTAGE MAXIMUM VOLTAGE
Vdc Vdc
OFF 0.00 0.89
1 0.90 1.79
2 1.80 2.69
3 2.70 3.59
4 3.60 4.49
5 4.50 5.39
6 5.40 6.29
7 6.30 7.19
8 7.20 8.09
9 8.10 8.99
10 9.00 10.00
Cabling Requirements
To avoid signal degradation use shielded, properly grounded
cables for all analogue and digital inputs and outputs. Route
input and output cables separately from power cables.
Interconnection wiring shall be separated by reinforced
insulation to any live parts.
BMS Terminal Connections
• Stripping Length = 9mm
• Tighten screwed terminal connections to 0.6 - 0.8 Nm

PLC MANUAL CONTROL
Each CW-H cooler can be manually controlled from the PLC
CONTROL screen. This mode is recommended for initial setup
and servicing only.
Ensure “MAN” is selected on the CONTROL screen.

• To enable Indirect Cool Mode – Set IEC = ON
• To enable Direct Cool Mode – Set DEC = ON (Supercool
Coolers Only)
• To enable VENT Mode – Set VENT = ON
Note - When vent mode is turned ON, IEC and DEC will
automatically turn OFF.
• For all modes, set the Fan Speed between 0 and 10 to run
the cooler.

COMMISSIONING
WATER MANAGEMENT SYSTEM
Tank (reservoir) drain valve control
• When power switched on to the cooler, the Drain Valve opens.
• Drain Valve remains open until COOL mode selected.
• When COOL mode selected the Drain Valve shuts.
• Drain Valve opens when:
• COOL mode switched OFF and tank drain delay is
activated. Drain Valve remains open until next COOL mode
activated.
• Salinity Control demands the tank (reservoir) to be drained.
(Refer to the Salinity Control section following).
Inlet solenoid valve control - water
• Opens 9 seconds after COOL mode starts (in order to give
Drain Valve time to shut).
• Opens every IEC pump cycle if water is below the high probe.
• Opens if water level is below the bottom probe in DEC mode.
• Remains open until water level reaches top probe.
• Will also open at anytime that Salinity Control demands fresh
water.
Pre-wet cycle
(Pre-wet runs the pumps for 3 minutes to ensure the heat
exchange Cores are fully saturated when COOL mode is
activated).
• Default setting - Pre-wet cycle enabled
• Pre-wet duration 3 minutes
• Pre-wet always occurs when COOL mode is selected after a
Mains power interruption.
If COOL mode is selected and the Mains power has not been
interrupted, then a Pre-wet will occur if the Drain has not been
activated since the last time COOL mode was selected.
• The fan speed drops to idle. Note: Fan speed will remain at
idle regardless of Wall Control/BMS setting.
• After Pre-wet, fan will resume running at Wall Control speed
setting.
Pump Control
• When COOL selected, fan and pump will start 30 seconds
after water level has reached the bottom probe
• After a pre-wet the IEC pumps cycle continuously:
ON for 1 minute
OFF for 8 minutes
• After a pre-wet the DEC pumps cycle continuously:
Salinity Control
• Water conductivity is updated every time water reaches the
high probe.
• When conductivity exceeds the upper set point a drain cycle
starts.
• Drain valve opens until water level falls below bottom probe,
then valve closes immediately, and inlet solenoid valve opens
to rell the reservoir.
• Will sense conductivity down to 9 µS (about 4ppm) (ie: rain
water).
Chlorinator Control
The Chlorinator is a pair of specially treated plates. When
energised and submerged in water, electrical current ows
between them generating chlorine. Chlorine is known to kill
bacteria in water supplies and the Climate Wizard Chlorination
system is designed to minimise bacteria levels within the cooler.
• Chlorinators are active at all times that the cooler is in COOL
mode, AND the water level is above the bottom probe AND
the water conductivity is >1500µs/cm.
• In the event that the water conductivity is <1500µs/cm for an
extended period of time, a 24 hour clean tank drain cycle will
commence.
INDIRECT WATERING CYCLE
When running in IEC mode the PLC Display will show the
following messages during the IEC watering cycle.
• Tank Level OK - Water lled to high probe and waiting for
next pump cycle.
• Indirect Pump Running - Pumps running as part of the
watering cycle (60 seconds).
• Core Drain - Pumps stopped and water returning to tank
(90 seconds)
• Tank Fill - Solenoid valve open and re-lling to high probe.
