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 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 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 bearing
structure.
• Ensure the installation complies with all
local and national regulations with regards
to electrical, plumbing and bushre
construction requirements.

TECHNICAL DESCRIPTION
AIRFLOW
The cooler has a single fan which draws hot outside air through
the rear-mounted airlters, through the dry channels of the air-
to-air indirect evaporative heat exchangers and into the plenum
at the front of the cooler.
Inside the plenum, the air is split into an exhaust ow and a
supply ow.
The exhaust air passes through the wet channels of the air-
to-air indirect evaporative heat exchangers, and out the upper
exhaust grille back to atmosphere.
The supply air passes over a secondary direct evaporative
cooling stage (Supercool cooler only), before entering the
customer's ductwork.
HEAT EXCHANGERS
Indirect Evaporative Cooling (IEC) Stage
All coolers have air-to-air indirect evaporative heat exchangers,
composed of alternating dry and wet channels seperated by a
membrane. CW-H10 has 2 and CW-H15 has 3.
Through evaporation and conduction, heat is transfered from
the air in the dry channels, across the membrane, and into the
air in the wet channels.
The air in the dry channels is progressively cooled, but gains no
additional moisture.
Direct Evaporative Cooling (DEC) Stage
Supercool coolers are tted with a secondary direct evaporative
cooling stage.
The cooled air from the IEC stage passes over saturated
Chillcel® media, where, through evaporation it is cooled further
with an increase in moisture content.

COOLER LOCATION
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 bearing structure.
Model Shipping Weight Operating Weight
CW-H10 250kg (550 lb) 255kg (560 lb)
CW-H15 340kg (750 lb) 330kg (728 lb)
CW-H15S, H15S Plus 355kg (783 lb) 345kg (761 lb)
Always locate the cooler where it will receive a plentiful supply
of fresh air, NOT in a recess where it may be starved for air or
where the air is polluted. Provision must be made for access to
electricity, water supplies and drains.
Air exiting the exhaust discharge is warm and heavily laden with
moisture. Ensure the cooler’s exhaust outlet location will not
cause corrosion or damage to other nearby items. Do not allow
exhaust air to re-circulate into the air intake of the cooler.
Ensure the location is a minimum of:
• 3.0m (10’) from a solid fuel heater ue
• 1.5m (5’) from a gas ue
• 1.0m (3.5’) away from adjacent solar panels or similar roof
mounted xtures
• 6.0m (20’) from a sewer vent
• 3.0m (10’) (preferably 5.0m (17’)) away from any TV antenna
or antenna cables. Make sure the cooler is not between the
antenna and the transmission tower that is providing the
television signal to the home.
ILL1925-A
Extra service or warranty charges may apply for the cost of any
equipment or additional labour involved in accessing the cooler

ELECTRICAL REQUIREMENTS
ELECTRICAL SUPPLY INSTALLATION
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/fuse at the
distribution board.
A mains isolation switch, with all pole disconnection, shall be
furnished by the contractor and installed adjacent to the cooler.
IMPORTANT! There are specic models for regional voltages
and frequencies which are not interchangeable. Specically, the
fan motor(s), transformer(s) and pump(s) may be unique to the
voltage/frequency of supply.
See the cooler rating label for the correct electrical data. Before
connecting the device, make sure the power supply matches
the cooler voltage and frequency.
Electrical Supply Specication :
380-415V / 50 Hz / 3 Phase with Neutral / 4.9A (FLA)
Mains power terminals are provided inside the electrical cabinet
with glands provided for cable entry.
MOTOR LOCKED-ROTOR PROTECTION
Due to the built-in motor locked-rotor protection, the starting
current (LRA) is equal to or less than the nominal current (FLA).
FIRE TERMINALS
A pair of terminals labelled "FIRE" are provided for integration
with a building re management system.
These terminals provide power to the controls PLC and are
supplied with a bridge.
To use with a building management system, remove the bridge
and connect the terminals through a NORMALLY CLOSED
relay which opens in a re event.
Interrupting power to the PLC will immediately stop all cooler
components, including fans.
HIGH LEAKAGE CURRENT
IMPORTANT! High leakage current. Earth connection
essential before connecting supply.
The cooler utilises a fan motor with a built in inverter drive. To
comply with EMC regulations, these drives adopt EMC lters
that connect to the motor earth terminals. The normal lter
leakage current to earth may accumulate to a total leakage
current in excess of 10mA. For asymmetrical power systems or
if a phase fails, the leakage current can increase to a multiple of
the nominal value.
To comply with regulations and to prevent electric shock, this
leakage current must be properly addressed.
In particular, the earth terminal at the mains power point of
connection must be properly connected and earthed. Power
must not be applied until this is correctly completed.
RESIDUAL CURRENT CIRCUIT BREAKER
(RCCB)
The cooler utilises a fan motor with a built-in variable speed
drive (VSD). If local electrical standards require the use of a
residual current circuit breaker (RCCB), only AC/DC-sensitive
residual current devices (type B) are permissible. If incorrectly
selected and/or sized, when the cooler power supply is
switched on, pulsed charging currents from the capacitors in the
integrated EMC lter can lead to the instant tripping of RCCB.

WATER SUPPLY INSTALLATION
The cooler requires a permanent water supply to be
connected. A built-in Inlet Solenoid Valve, controlled by the
water management system, allows water into the cooler when
required.
INSTALLATION OF THE WATER SUPPLY 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)
10L/min (2.6 gal/min) MINIMUM
20L/min (5.3 gal/min) RECOMMENDED
Water Supply Temperature:
40°C (105°F) MAXIMUM
Water Supply Salinity:
100 to 1150μS/cm
Important! Water supply pressures which are lower than
100kPa (15 PSI) and higher than 800kPa (115 PSI) will prevent
the inlet solenoid valve from opening.
Water pressures which are higher than 1200 kPa (175 PSI) and/
or water temperatures which are higher than 40ºC (105ºF) risk
inlet solenoid valve failure.
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.
If a non-return valve is installed in the water supply line, it
is recommended that a suitable pressure relief valve is also
installed between the cooler and non-return valve to limit the
pressure rise associated with the heating e󰀨ects of ambient
temperature and solar radiation.
WATER SUPPLY ISOLATION
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 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.
WATER SUPPLY FILTRATION
The Installer must provide an inlet water lter in the water
supply line, external to the 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 inlet solenoid valve, preventing it from functioning
correctly.
The cooler'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 unusually high or low levels of salinity,
hardness, acidity or chemical contaminants, then additional
ltration or treatment systems should be employed to render the
water ‘potable’.
WATER DRAIN INSTALLATION
The cooler requires 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.
INSTALLATION OF THE WATER DRAIN MUST CONFORM
TO LOCAL PLUMBING RULES, REGULATIONS AND
STANDARDS.
The cooler installation kit contains components to congure the
Drain Valve discharge to one of the following options;

WATER REQUIREMENTS
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.

CW-H INSTALLATION, OPERATION & MAINTENANCE MANUAL 859749-G |17
WATER MANAGEMENT SYSTEM
The cooler contains multiple parts to supply, distribute and
manage the water needed for the heat exchangers.
Water Inlet Solenoid Valve
The inlet solenoid valve allows water into the water reservoir. It
is open during the following phases.
• Initial Tank Fill
Trigger: Entering IEC or DEC mode.
• IEC Tank Fill
Trigger: Indirect Watering Cycle = TANK FILL.
• DEC Only Tank Fill
Trigger: Low Probe = WET.
Once open, the inlet solenoid valve will remain open until the
water high probe has detected water for at least 5 seconds.
If the water drain valve is open, the inlet solenoid valve will
remain closed.
Indirect Pump Control (IEC Watering Cycle)
The indirect pumps move water from the reservoir to the 3
indirect heat exchangers.
The indirect heat exchangers do not require continous watering
and the pump runs on the following cycle
• Tank Level OK - Water lled to high probe and waiting for
next IEC pump cycle to start.
• Indirect Pump Running (60 seconds).
• Core Drain - IEC pump stopped and excess water is
draining back to the reservoir (1 minute 30 seconds)
• Tank Fill - IEC pump stopped and inlet solenoid valve open
and re-lling to high probe (6 minutes 30 seconds)
Total IEC pump on time = 1 minute
Total IEC pump o󰀨 time = 8 minutes
Direct Pump Control (Supercool coolers only)
The direct pump moves water from the reservoir to the Chillcel®
media. When running in DEC mode the direct pump runs
continuously. Excess water from the Chillcel® media drains
back to the reservoir.
Water Salinity Control
As water evaporates from the heat exchangers, the salinity of
the remaining water naturally increases.
The water management system uses the 3-pin water probe to
measure water conductivity as a proxy for salinity. The probe
can sense conductivity down to 9 µS (about 4ppm) .
Water conductivity is updated every time water reaches the high
probe and, when it exceeds the upper set point, a salinity drain
cycle will start.
Chlorinator Control
The chlorinator is a pair of specially treated plates. When
energised and submerged in water, electrical current ows
between them generating chlorine which is known to kill
bacteria in water supplies.
The chlorinator is active when the cooler is in IEC mode, AND
the water level is above the bottom probe AND the water
conductivity is >1500 µs/cm.
If the water conductivity remain <1500µs/cm for 24 hours a
clean tank drain cycle will start.
COOLER CONTROL COMPONENTS
Water Tank (Reservoir) Drain Valve
The drain valve will automatically open when power is rst
applied to the cooler. It will close again when IEC or DEC mode
is enabled.
During a salinity drain cycle, the drain valve opens until the
water level falls below the low probe, then the drain valve
closes immediately, and inlet solenoid valve opens to rell the
reservoir with fresh water.
During a clean water drain cycle, the drain valve remains open
for 10 minutes, after which the inlet solenoid valve opens to rell
the reservoir with fresh water.
The drain valve will open if it has been 3 days since IEC or DEC
mode was last run.
CONTROL COMPONENTS
Cooler logic and controls are handled by a PLC in conjuction
with a Water Manager PCBA, both located in the controls
enclosure.
PLC WATER MANAGER PCBA
INPUT AND OUTPUT TERMINALS
A series of input and output terminals are located on the door of
the controls enclosure.
