EMPLOYER AND EMPLOYEE RESPONSIBILITIES
The installation and maintenance of evaporative coolers at height has the potential to create Occupational 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 offer practical guidance on these health and safety issues. Compliance with these regulations will require appropriate work practices, equipment, training and qualifications of workers.
Seeley International provides the following information as a guide to contractors and employees to assist in minimising risk whilst working at height.

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 difficulty, 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 firm, 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 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?
OTHER IMPORTANT REQUIREMENTS · Never force parts to fit because all parts are
designed to fit 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 bushfire construction requirements.
MAINTENANCE NOTE
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 filled 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 fill out the maintenance schedule, will void your warranty.

TECHNICAL DESCRIPTION

AIRFLOW
The cooler has a single fan which draws hot outside air through the rear- mounted air filters, through the dry channels of the airto-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 flow and a supply flow.
The exhaust air passes through the wet channels of the air-toair indirect evaporative heat exchangers and out through 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 separated by a membrane. CW-H10 has 2 and CW-H15 has 3.
Through evaporation and conduction, heat is transferred 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 fitted 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.

Min. forklift tyne gap 460mm (18.2″)
ILL1916-A
LIFTING THE COOLER
The cooler may be lifted by crane with slings through the cooler base forklift truck tyne openings. Do not attempt to lift using any cabinet features or by retrofitting lifting lugs. The cabinet may be damaged and/or lift safety compromised. It is recommended to use a spreader bar on the straps or slings to protect the upper edges of the cooler with a corner protector beneath the lifting straps to avoid any damage to the cabinet during the lift.
UNPACKING THE COOLER
The cooler will be delivered on a dedicated pallet and will be wrapped in plastic film which will need to be removed before installation. A small bag of installation components along with the exhaust transition side rails and grilles can be found under the lid of the main cabinet of the cooler. The exhaust transition will need to be raised into place before operation. WARNING: Once unwrapped, the exhaust transition assembly should be fitted together as soon as practicable to avoid loose components becoming lost/damaged and/or a hazard.

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 cooler exhaust is warm and heavily laden with moisture. Ensure the cooler’s exhaust air 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 cooler location is a minimum of:
· 3.0m (10′) from a solid fuel heater flue
· 1.5m (5′) from a gas flue
· 1.0m (3.5′) away from adjacent solar panels or similar roof mounted fixtures
· 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.
ACCESS FOR SERVICING AND MAINTENANCE
The cooler should be installed in a position that allows adequate access for installation, and future maintenance and servicing activities. This should comply with installation guidelines and any local, State and National regulations.
Consider the following for installation location:-
· Which has clear access to and around the cooler
· Which is clear of fixtures in line with below clearances
· Which is clear of fall edges (> 3m (10′) away)
· Which is structurally capable of supporting the weight of the cooler and service technicians
Required clearances around the cooler for future maintenance and servicing are shown below.

MOUNTING/SUPPORT
Roofstands, accommodating 0-10 roof pitches, are available for order via Seeley International. See Optional Components List.
ILL2426-A
The cooler base has a series of mounting holes for securing the cooler. Dimensions and locations of the mounting holes are shown in the cooler views at the beginning of this manual. Where necessary, installers should use a sufficient number of suitably rated vibration isolation mounts to support the operating mass of the cooler.
DRIP-TRAY
When coolers are installed indoors, or anywhere that water leakage could cause damage, install a corrosion resistant drip tray under the whole unit. Recommended sizes: CW-H10: 1500 x 1300 x 50mm (59″ x 51″ x 2″) CW-H15, H15S, H15S PLUS: 1500 x 1900 x 50mm (59″ x 75″ x 2″) Apply silicone sealant between drip-tray and cooler base at every fixing.
SUPPLY AIR DUCT CONNECTIONS
Dimensions for the supply air duct interface are shown in the cooler views at the beginning of this manual. Vibration absorbing flexible connections are recommended for all duct connections to the cooler. All ducts must be independently supported. All duct direction changes must utilise a generous radial turn with internal air directors to minimise turbulence and maximise efficiency. All ducts are to be suitably insulated to minimise temperature losses.

ILL1925-A
Extra service or warranty charges may apply for the cost of any equipment or additional labour involved in accessing the cooler if these guidelines are not met.
Note! Do you need to discuss the installation of items like safety anchor points with the customer?

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 specific models for regional voltages and frequencies which are not interchangeable. Specifically, 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 Specification (50Hz Option):
380-415V / 50 Hz / 3N~ / 4.9A (FLA)
Electrical Supply Specification (60Hz Options):
440-480V / 60 Hz / 3~ / 9A (FLA) 11.5A (MCA) 15A (MOPD)
200-240V / 60 Hz / 3~ / 11A (FLA) 14.5A (MCA) 20A (MOPD)
200-240V / 60 Hz / 1~ / 8A (FLA) 10.5A (MCA) 15A (MOPD)
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).

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 filters that connect to the motor earth terminals. The normal filter 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, pulsed charging currents from the capacitors in the integrated EMC filter can lead to the instant tripping of RCCB when the cooler power supply is switched on.
FIRE TERMINALS
A pair of terminals labelled “FIRE” are provided for integration with a building fire management system.
These terminals provide power to the cooler controls 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 fire event.
Interrupting power to the PLC will immediately stop all cooler components, including fans.

24VDC POWER SUPPLY
The cooler is provided with a 24VDC switch mode power supply for use with internal components and optional sensor accessories. The maximum power available for external components is 30W.

TRANSFORMER TAPPINGS
440-480V / 3~ coolers ONLY are fitted with a transformer to power the cooler electronics. By default the input voltage jumper is set for 480V. If the power supply has a different phase-to-phase voltage, reposition the jumper as per the table below.

The following specifications for water supply are required:
Water Connections: ½” BSP (Aus/Eur), ½” NPT (USA) male connection supplied suitable for a compression fitting.
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 1150S/cm

WATER SUPPLY FILTRATION
The Installer must provide an inlet water filter 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, filings or dirt) before final fitting. 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 classified as potable’ and fit 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 filtration or treatment systems should be employed to render the waterpotable’.
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 fit an appropriate water hammer arresting device external to the cooler.

WATER SUPPLY PRESSURE REGULATION

The Installer must provide a pressure regulator in the water supply line adjacent to the cooler to regulate water supply pressures between 100kPa (15 PSI) and 800kPa (115 PSI).

Important! Water pressures which are lower than 100kPa (15 PSI) will prevent the inlet solenoid valve from opening.

Important! 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.
Water pipes installed on the outside of a building, or any other exposed location, shall have adequate insulation to protect against freezing in the winter and solar radiation heating in the summer.

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 the non-return valve to limit the pressure rise associated with the heating effects of ambient temperature and solar radiation.

WATER SUPPLY ISOLATION
The Installer must provide a manual 1/4 turn ball type shut off 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.

16 | CW-H INSTALLATION, OPERATION & MAINTENANCE MANUAL 859749-I

WATER REQUIREMENTS

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 STANDARDS. Drain Connections: The cooler installation kit contains components to configure the drain valve discharge to one of the following options: – Down or Rear Discharge – 1.5″ (40mm) BSP Male or 1.5″ Flexible Coupling. Drain Rate: 15 L/min (4 gal/min) Important! Water drained from the drain valve is high in salinity and must be carried away to a suitable discharge point on the building or property. Never drain the water directly onto the roof
ILL2442-E
ILL2443
The removable access panel should be re-assembled after drain line installation. Important! Drainage systems with long pipe runs, multiple entry points, and/or incorporating traps shall use a tundish or similar device to create a 25mm (1″) air-gap between the bottom of the drain valve and the drainage system.

CW-H INSTALLATION, OPERATION & MAINTENANCE MANUAL 859749-I | 17

COOLER CONTROL COMPONENTS

FAN SPEED MANAGEMENT SYSTEM
The cooler fan is driven by an electronically commutated DC motor with integrated variable speed drives (VSD) that allows for 0-10Vdc speed control.
The fan speed is controlled by the inputs from the Primary Control Method (e.g. Multi-Magic Wall Controller). Depending upon the control type, speed control is either continuously variable or in 10 discrete speed steps (Speed 1-10).
If, when commanded to start, the fan start delay option is enabled, the fan will remain off until the delay timer has expired. Upon starting, the fan will initially run at a fixed slow speed for 30 seconds before increasing to the requested speed.
If pre-wet is enabled, the supply fans will remain at the fixed slow speed until the pre-wet cycle is complete.
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 continuous watering and the pump runs on the following cycle
· Tank Level OK – Water filled 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-filling to high probe (6 minutes 30 seconds)
Total IEC pump on time = 1 minute
Total IEC pump off 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 flows 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.
Water Tank (Reservoir) Drain Valve
The drain valve will automatically open when power is first 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 refill 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 refill the reservoir with fresh water.
The drain valve will open if it has been 3 days since IEC or DEC mode was last run.

COMMISSIONING

AIR FLOW BALANCING
In order for the cooler to produce cool air it is mandatory that some of the inlet air is forced to return through the indirect heat exchanger cores and be exhausted to atmosphere. Therefore only a proportion of the total inlet air is delivered into the cooled zone.
THIS PROPORTION IS CRITICAL TO ACHIEVING SATISFACTORY PERFORMANCE.
The supply air transition is equipped with a damper that can be adjusted to ‘balance’ the proportion of supply and exhaust air streams. Damper position is controlled through a lever with locking screw located underneath the supply air transition. The damper will need to be adjusted during commissioning depending on the external static pressure of the duct system.

To balance the air flow.
1. Ensure all side panels and air filters are in place
2. Connect all external supply and exhaust ductwork.
a. Stand-alone Cooling: Fully open all supply air outlets in the entire ductwork system.
b. Pre-Cooling: Ensure all main Air Conditioning plant fans are running at full speed – consult with Building Manager and/or Air Conditioning contractor.
3. Using the cooler’s PLC, start the Climate Wizard in LOCAL and IEC modes at Speed 10.

ILL3884-A

ILL2447-A
There is a hole in the right hand side of the supply air transition suitable for manometer tubes for measuring pressure.
NOTE! Pressure measuring should be carried out using an accurate instrument, either electronic or “inclined tube manometer”. DO NOT GUESS.

4. Wait approximately 5 minutes, to allow the cooler to complete the first water fill and the pumps to start.

5. Adjust the supply air transition damper until the pressure in the transition stabilises as follows:

a.CW-H10:

200 Pa (0.80 in wg static)

b.CW-H15:

175 Pa (0.70 in wg static)

c.CW-H15S: 175 Pa (0.70 in wg static)

d.CW-H15S Plus: 210 Pa (0.84 in wg static)

6. For multiple CW-H coolers connected to the same supply duct, it may be necessary to re-check and adjust the supply air transition pressures of all coolers after each cooler is set.

7. For stand-alone cooling, balance all customer’s supply air outlets in your usual manner. After balancing, check and adjust the CW-H damper back to the above values.

8. Lock the damper in its final position and record the final value

MAINTENANCE SCHEDULE

MAINTENANCE FREQUENCY
Maintenance of an indirect evaporative cooler is essential in maintaining proper performance and reliability.
All maintenance must be done by competent, qualified, licensed technicians, in accordance with National and/or Local Regulations.
The frequency of service is largely dependent on the conditions under which the cooler is operated. External factors, such as air and water quality, can affect the serviceable life of the cooler and its components. In particular, installations using hard water, usually defined as greater than 200mg/L, will experience greater scaling problems requiring a more frequent cleaning regime.
Similarly, the amount and type of use can also have a significant impact. The guidelines listed below are intended to provide help in formulating a proper service regime. Local, and in some cases, individual factors should be taken into account when deciding on the frequency of visits.
HEALTH REGULATIONS. In some regions, regulations require that evaporative air coolers be serviced at specific intervals. Ensure all maintenance is done in accordance with any local and national regulations.

MAINTENANCE SCHEDULE SERVICING FREQUENCY

AIR FILTERS

CHLORINATOR

COMMERCIAL / INDUSTRIAL INSTALLATIONS (Seasonal use)
COMMERCIAL / INDUSTRIAL INSTALLATIONS (All year use)

Maintenance Schedule servicing must be a minimum of twice a year, typically immediately before and after the summer season.

Air filters should be cleaned every month of operation and replaced every
year.

Chlorinators should be cleaned during each service and replaced every 4 years.

Maintenance Schedule servicing must be performed every 3 months.

Air filters should be cleaned every month and replaced every year.

Chlorinators must be cleaned during each service and replaced every 2 years.

While installation is not covered by warranty (e.g. duct work, roof penetrations, electrical and water connections etc.), these items should be checked as they can affect the performance (and/or safety) of the cooler. For this reason, they are included in the Maintenance Schedule.
For access to Technical/Installation/Service Information register online at www.seeleyinternational.com/service

WINTER OPERATION AND SHUTDOWN
Climate Wizard coolers cannot be used in any cooling mode (INDIRECT, DIRECT or SUPERCOOL) in freezing conditions. In particular the inlet water solenoid valve, pumps, and drain valve are likely to fail in such conditions.
It is recommended that, to prevent damage to cooler components, the following tasks are completed before the start of the winter season.
1. Drain and clean the reservoir. 2. Drain down and isolate the water supply. 3. Isolate the power.
For installations requiring continuous operation through the winter, it is possible to run the cooler in VENT mode down to -20oC (-4oF), however customers must ensure the controls are not accidently set to any cooling mode in these conditions.

MAINTENANCE INSTRUCTIONS

INDIRECT HEAT EXCHANGERS
The indirect heat exchanger cores do not require any maintenance other than visual inspection, which can be completed without removal from the cooler.
However it is recommended that, after 7 years of operation and for each subsequent year of operation, all indirect heat exchangers are removed for a detailed inspection.
During a full inspection, check the following areas.
· Air intake face and dry channels are clear of dirt, debris and calcium build up.
· Glue seams are fully sealed, with no splits greater than 10cm. · Wet channel air-entry slots are not bridged by calcium build
up.

7. The cores can now be slid out from either side of the cooler through the access panel openings. Take care to ensure the cores are not damaged during removal. They can be heavy and fragile when wet. Grasp the cores around the top section to ensure no delamination of the core occurs while moving them.

CORE AND SPREADER ASSEMBLIES (LID REMOVED)

1. Power OFF, water OFF.

ILL2450-B

2. Disconnect and remove any fixed ducting from the exhaust outlet of the cooler (if fitted).

3. Remove the exhaust transition/lid assembly from the cooler.

ILL3939
5. To re-assemble, first note the Chillcel has a small header block; this is the top of the pad and must be positioned under the water spreader for the pad to function correctly.
6. Ensure the re-fitted Chillcel sits upright against the water spreaders and tightly against each other.

ILL2460-A
11. Ensure a good seal between the cores and the access door when closing. When re-securing the access doors, start from the bottom screws and work up.
12. Refit the core clamp strips clamping over the extrusion located at the top of the cores.

ELECTRICAL ENCLOSURE
The cooler electrical controls enclosure is manufactured from steel coated in a thermosetting epoxy polyester powder paint. Care should be taken to avoid causing deep scratches, dents or cleaning using an abrasive brush. Wipe clean with sponges and clean water.
Any local areas of corrosion or cracked paint can be treated by applying a heavy duty, zinc-rich, anti-corrosive coating, often called “Zinc Rich Primer” or “Cold Galv”. First ensure the surface is free from dust, dirt, grease, oil, rust, scale and other contaminants and then follow the coating manufacturer’s application instructions.

ILL2461-A
13. Refit the exhaust transition/lid assembly to the cooler.
14. Refit any fixed ducting to the exhaust outlet of the cooler.
