Employers and Employees Responsibility
The installation and maintenance of evaporative cooling units, particularly at height, has the potential to create Occupational Health and Safety (OH&S) 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/European Directives, 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 actions 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 occurring?
  • What could the possible consequences be?
  • What can be done to reduce, or better still, eliminate the risk?

---|---

Handling the Unit

  • Braemar RPA OR units are provided with lifting external points.
  • The cooler must remain in the upright position at all times.

Positioning the Cooler
The unit should be installed so that it is level. Allow 1200mm clearance around the unit. Air intake to the unit should not be restricted in any manner. Approval should be sought by Seeley for any installation encroaching on these limits. No modifications shall be made to the unit. If the unit is being installed on a sloped roof, a roof stand shall be installed and adequately secured before the RPA OR unit is installed.

  • Wiring Electrical
    Connections must be in accordance with all relevant Australian Standards/European Directives and applicable State regulations and local legislation.

  • Drainage
    Drainage for the cooler section shall be done in accordance with relevant Australian Standards (AS3500)/European Directives and statutory requirements and local legislation.

  • Occupational Health and Safety

    • When a unit is being decommissioned it shall be physically disconnected from the water supply, purged and sealed. Where possible components should be recycled in accordance with government regulations.
  • Operational Safety

    • RPA OR Evaporative Coolers must not be operated until the unit has been commissioned by a qualified person. The unit should not be operated if any safeguards, panels or controls have been removed, damaged or bypassed.
    • If the unit is not operating as intended turn off the unit at the wall switch and then isolate the power and water supply. The unit should remain isolated until a qualified service technician has inspected the unit and resolved any issues.

Safety Points to Consider

  • What is the best and safest access to the roof and/or work 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.)
  • Has the roof section or structure been assessed to ensure that it can withstand the load of the appliance and workers.
  • Does the worker have appropriate foot wear?
  • 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?
  • Is the person conducting the installation and maintenance appropriately qualified and familiar with local authority and Australian Standards/European Directives.

Legionnaires Disease

  • Evaporative air conditioners have not been implicated in any outbreak of Legionnaires disease, although Legionella bacteria have been found in such systems. The water temperature in the evaporative air cooler section is normally at about 18°C at which temperature the Legionella bacteria (if present) will remain dormant and cannot multiply.
  • The following maintenance schedule is required to be followed in order to comply with the New South Wales Public Health Act 1991 section 46:-
    • Sumps are to be drained and cleaned at three monthly intervals or more frequently if necessary.
    • Wetted pads are to be drained and cleaned at three monthly intervals or more frequently if necessary.
    • Water strainers are to be cleaned at three monthly intervals or more frequently if necessary.
    • If any air filter is fitted, it is to be cleaned or replaced when necessary.

Airborne Noise Emmissions
RPA OR units generate noise during operation. The operator is generally not located near by the machine therefore hearing protection is unlikley to be required. Commissioning and maintenance technicians may require hearing protection with each installation to be assessed by the technician completing the work.

TECHNICAL SPECIFICATION

  1. Construction
  2. The frame is a aluminium body and external cabinets are marine grade painted aluminium.
  3. Units have Black MagicTM Mini-Cell Chillcel® cooling pads. Alternative Aspen pads available by customer request.
  4. Blower
  5. The standard blower fan is forward curved and constructed from steel.
  6. Blower housings are rotor molded plastic as standard.
  7. Fan Motors
  8. Fan motors are mounted externally to the blower and connect via a set of pulleys.
  9. All units come with a specified motor power capable of meeting flow and pressure requirements.
  10. Pulleys
  11. A single pulley combination is supplied with each unit.
  12. Variations in external pressure drop outside of the standard product offering, may require pulley and belt combinations to be supplied by the customer.
  13. Electrical Control and Connection
  14. All units have an electrical starter box housed inside the unit.
  15. Refer to Appendix A for wiring diagrams.
  16. Units may be controlled by Wall Switch.
  17. Units will require single or 3 phase power depending on motor type.
  18. Supply Water Specification
    Water consumption rates vary with weather conditions but the following can be used as a guide. The evaporative cooler can evaporate around 2.5L of water per hour for every 100L/s of supply air. A cooler providing 4,000L/s of air could evaporate 2.5 x 40 = 100L of water per hour of operation. The water bleed off rate must be added to this in order to calculate the total operating water flow rate.

Relief Area Calculation
Evaporative air coolers always run on 100 % fresh outside air. Always ensure adequate relief is available via open doors and/or windows. Allow approximately 0.4m² per 1000L/s of supply air. If 0.5mm fly wire screens are fitted to the relief area, allow 0.8m² per 1000L/s for this area. Contact manufacturer if other fly wire thicknesses are installed.
Example: RPA450 OR – 3kW Cooler with 100Pa pressure drop Air delivery will be approximately 4,000 L/s (refer spec sheet)

If no fly screens are fitted to relief openings: m0.4 2 x (4,000 L/s / 1000 L/s) = 1.6m2 relief area required If fly screens are fitted to 70% of the relief openings: m[(0.8 2 x 70%) + (0.4 m2 x 30%)] (4,000 L/s / 1000 L/s) = 2.72 m2 relief area required (minimum)

  • Select relief openings to provide the best pattern of cool air flow throughout the building. Note that relief openings may be ineffective if exposed to high winds. If air exhaust volume is a problem, mechanical exhaust ventilation will be required for as much as 80% of the air delivery of the cooler.
  • Coolers must not discharge into a closed space but must always be able to relieve from a building.
  • If supply air ducts are fitted with adjustable outlet grill blades, the blades should be adjusted to give the best cool air distribution in the area served by the outlet. Do not close blades too far or air whistle may occur.
  • To ensure long life and efficient operation it is essential that the cooler receive an annual service. In extreme environments (e.g. hot dusty areas) more frequent service may be required. Check with the unit installer.
  • During normal operation of the cooler it is important that the water bleed-off is operating and is not shut off or blocked. This bleed-off will prevent an accumulation of salts and solids in the unit.

Drainage

  • All RPA OR coolers require adequate drainage to remove water from the unit. It is the installers responsibility to ensure that the drain is adequately sized to accommodate the unit.
  • The local drains shall be sufficient to remove the excess water required to clean out the unit as required.

INSTALLATION
The following recommendations are not intended to supplant or take precedence over relevant official regulations. Braemar RPA OR Evaporative Cooler units are designed essentially as a roof top or external ground mount unit.

Location
This equipment is not designed for long and complex air distribution ductwork and as such the unit should be located as close as practicable to the points of air distribution. Depending on large volumes of 100% fresh air, care must be taken to locate the unit clear of kitchen exhausts, heavy vehicle traffic, industrial fume discharge etc. that may allow odour or fume laden air to be drawn into the unit. The prime requisites for the correct location of a unit is an unrestricted supply of clean fresh air.
When selecting a location for the RPA OR Evaporative Cooler unit the following shall be considered.

  1. Will the unit be suitably protected from the effects of corrosion and/or dust laden environments and any likelihood of physical damage?
  2. Can qualified personal perform functional adjustments and maintenance on the unit?
  3. Does the chosen location prevent a hazard to the building or structure or to the contents of the building?
  4. How to minimise the risks associated with storage, use or release of hazardous or flammable substances in the vicinity of the unit?
  5. How to minimise risk of harm to persons?
  6. Will the noise of the unit operating affect persons nearby? Units should be located so that quiet areas such as bedrooms, living rooms, meetings rooms etc. are not affected for both the premises that the unit is being installed and adjoining properties.
  7. A structural engineer is to be engaged to prove that the supporting structure is suitable for a fully laden unit.
  8. Ensure any skylights within 3m of the units have adequate fall protection installed.
  9. Long or complex ductwork will increase the static pressure on the system which may require alternate pulleys, belts and/or motor. Units are inly supplied with one motor and pulley set. Where changes are required it is the responsibility of the customer to supply and change. Contact Seeley International for assistance if required.

Clearance Around Unit Plant Room

  • It is not recommended to install a RPA OR Evaporative Cooler in an enclosed plant room. This should be evaluated at the design stage. Failure to identify negative pressure situations where harmful emmissions are being produced by other appliances may result in harmful emmissions being drawn into the building. It is the customers responsibility to ensure that this situation cannot occur as it may lead to serious illness and/or death.
  • If a cooler is placed in a plant room a suitably qualified engineer must be consulted to ensure that enough clean airflow is entering the plant room.
  • If the unit is installed in an external plant room a suitably qualified engineer should be engaged to ensure that other plant that may generate harmful gases and fumes are located at a distance such that the gases and fumes will not be drawn into the building.

Roof Stands
If a roof stand was supplied with the unit it is to be installed in accordance with the accompanying manual. If the customer chooses to use a 3rd party support structure they must be adequately and professionally designed by a structural engineer to support the operating weight of the unit.

Unit Weight

MODEL| NET WEIGHT (kg)| SHIPPING WEIGHT (kg)| OPERATING WEIGHT(kg)
---|---|---|---
RPA320 OR| 115| 140| 190
RPA400 OR| 120| 145| 195
RPA450 OR| 125| 150| 200
RPA500 OR| 125| 150| 200

Table 2: Unit Weights

Lifting

  • Units are to be lifted by the points specified and designed to lift only the specific units’ dry weight. The unit cabinet is lightweight aluminium and at no point should the lifting slings or spreader bar contact the cabinet, failure to comply will permanently damage the case.
  • Lifting point securing bolts and lifting eyes must be inspected for prior to lifting to ensure all bolts are installed, of correct tensile strength and are correctly tensioned. If any damage is observed, lifting points and/or eyes should be replaced. SEELEY-INTERNATIONAL-OR-Series-Industrial-Air-Conditioners-01 \(16\)

Positioning and Securing

  • Cabinet units are supplied with a base frame. Units are designed to be supported along the length of the frame. Lifting points on the roof of the cabinet are NOT to be used for anything other than lifting.
  • It is the responsibility of the installer to ensure that any platform used to support the unit is suitably designed. A suitably qualified Civil or Structural Engineer must be engaged to conduct an assessment. Units are not to be mounted via lifting lugs i.e permanently suspended by lifting points.SEELEY-INTERNATIONAL-OR-Series-Industrial-Air-Conditioners-01 \(17\)

Duct Connections
It is the installers responsibility to adequately secure the ductwork to the unit. A flexible connection comes attached with each RPA OR unit.

Fitting Instructions

  1. Position the flexible connector with the seam to the side over the protruding blower housing outlet. If connector is too loose, pull connector tightly around, pinch, fold back excess and hold in place with tape. Failure to do so may cause connection to flap and cause premature failure.
  2. Fit metal channels outside skirt.
  3. Fit first channel using the rivets supplied, starting from the centre and working towards the ends. The top edge of the channel is intended to be level with the edgeof the opening in the cooler. This is not essential and may be adjusted to suit installation.
  4. Secure remaining channels to the cooler outlet in the same manner as above.
  5. Install ductwork between 250mm and 320mm from the unit.
  6. Secure remaining channels to the side of the ducting with rivets in the same manner as step 3.
  7. Seal with Silicone after completion.SEELEY-INTERNATIONAL-OR-Series-Industrial-Air-Conditioners-01 \(18\)

ELECTRICAL CONNECTIONS

Electrical Supply

  • All electrical connections are to be as per AS3000/European directive. All electrical work shall be performed by a registered electrical contractor. Appendix A: Electrical Information, provides a comprehensive electrical connection guide including wiring configurations for different control setups and wiring diagram package and should be used in conjunction with this manual.

WATER CONNECTIONS

Water Supply

  • The supply pipe should be suitably sized to meet the specified flow and pressure. A ¼ turn ball isolating valve must be installed on the supply pipe near the unit for ease of maintenance. Do not use duo or non-return (check) valves of any kind including stop taps with jumper washers.
  • NOTE: Non-return type valves can have an effect on the operation of the water solenoid valves. They may lock up and damage can be caused.
  1. Fit water supply isolation close to the unit to assist in routine servicing.
  2. Before connecting the supply pipe, flush it clear of any swarf or debris that may cause the float valve to stick and leak.

NOTE: In areas where water pipes freeze, provisions will be needed to drain the water piping to prevent damage.SEELEY-INTERNATIONAL-OR-Series-
Industrial-Air-Conditioners-01 \(20\) Water Setup
RPA OR Evaporative Cooler units come with internal water components pre- plumbed. Once the unit is in position the water supply to the unit and drainage from the unit will need to connected.

Drain
The combination drain/overflow pipe outlet must be connected to a drainpipe with sufficient capacity to take the discharge of water from the reservoir. The pipe must connect to a suitable drain or gutter. Drain must be lower than base of pad assembly.

SEELEY-INTERNATIONAL-OR-Series-Industrial-Air-Conditioners-01
\(22\)Automatic Drain Valve

  • An optional automatic drain valve (Auto Drain Kit Installation 077444) is available. The valve either replaces the Drain or can be installed in addition. The ADV is designed to empty the sump at the end of a cooling operation. There are multiple configuration options what are explained in detail within the ADV manual. The ADV manual shall be used to ensure correct installation and operation.
  • The Auto Drain Kit is supplied with a solenoid to control water flow into the unit. Where a solenoid is installed a back flow prevention device and/or check valve must not be installed.

Bleed off Valve
To reduce the accumulation of salts and minerals in the re circulated water it is essential to bleed a certain amount of water to waste, Increased flow of makeup water reduces the salt content. The bleed rate will vary with the water supply quality, but initially should be set to Table 2: Bleed Off Rate. The bleed line from the flow delivery line inside the unit, must be suspended through the overflow pipe or into the optional automatic drain valve.

Cooling Pads
All units have removable cooling pads that provide access to the internal components of the cooler.

The following steps can be used to remove cooling pads:

  1. Confirm that the unit is not operating and that the power is isolated. Do not remove pads whilst the unit is operational.
  2. Lift pad vertically using a flat head screwdriver on the pad frame assembly shown in Figure 11: Cooling Pads.

  3. Check that the belts are correctly fitted and tensioned. Refer to manufacturer’s literature for tensioning methodology and tension requirements. As a general rule for tensioning belts, a deflection of 1.6 – 1.8 mm per 100 mm of belt span is required. The belt span is measured from the centre of the motor pulley to the centre of the fan pulley. (E.g. A belt with a span of 800mm should have a maximum belt deflection of 12.8-14.4mm.)
  4. Confirm the fan direction. If the fan is spinning in reverse, check the wiring diagram to ensure that the motor is wired in correctly. Fan direction is to be checked on high and low settings.

WATER CHECKS
Incoming Water Supply Checks

  1. Turn OFF main isolator and follow LOTO procedures. Failure to do so may result in Injury or Death.
  2. The water connections are to be completed by a licensed and experienced person.
  3. Confirm that the base tray is free of debris and clean.
  4. Confirm that the drain pipework is connected and sealed.
  5. Confirm that incoming water lines where flushed prior to de-isolating ball valve for unit water supply.
  6. Check the incoming pressure to the unit is at least 220kPa and not exceeding 800kPa.
  7. Confirm that there is sufficient flow to the unit so that all pumps can operate at 100% demand.

Internal Water Checks

  1. Open the ball valve controlling supply to the unit.
  2. Allow the reservoir to fill to 5mm below the overflow line and confirm that the float valve shuts off the incoming supply.
  3. Allow for the reservoir to remain full for a minimum of 30 minutes periodically checking for leaks.
  4. By pushing the ball float down confirm that the overflow/drain works.
  5. If an automatic drain valve has been provided activate the solenoid to test functionality. Refer to Auto Drain Valve manual for instructions.

START UP PROCEDURE

  1. Turn off power isolating switch and remove pad assemblies from the cooler.
  2. Turn blower by hand and check that all moving parts run freely. CAUTION: Do not put fingers through the blades at any point
  3. Check fan/motor belt deflection and adjust if necessary
  4. If necessary, wash out reservoir.
  5. Check operation of isolation switch.
  6. Check and set water distribution by adjusting the water restrictor in the hose from the cooler’s water pump to the distribution pipe. Set to ½ open initially with adjustment of the saturation of the cooling pads outlined in 4.6 Setting Pad Saturation.
  7. Measuring the flow rate from the water bleed. Using Table 3: Bleed Off Rate adjust the bleed valve to fill 1L in the time shown according to the air flow rate and hardness of the water.

Note:- Formation of salt deposit in cooler pads indicates insufficient bleed off.

Table 3: Bleed Rates

  • Check and ensure sufficient air relief is available via operable windows and/or doors in the cooled area. Required relief calculations as per 2.5.7 Relief Area Calculation.
  • Check that sufficient relief area is provided for a full load current check. Load test motor with a Tong-test or clip-on ammeter. If the motor amps are over the rating plate adjust pulley ratio or increase duct pressure drop to reduce amps to equal to or below ratings as shown on fan motor compliance plate. Pulley ratio change is the responsibility of the installer.
  • Run pump for five minutes to ensure the pads are saturated with water. Run fan on high for five minutes. Shut down unit and isolate power following LOTO procedures. Remove pads and check that fan motor, pump motor, fan etc. are not being splashed with water.
  • Check belt tensions and pulley alignment and adjust if necessary. Check to ensure that the blower wheel has not shifted. If unsure please contact a Seeley International service agent.
  • Ensure that a maintenance schedule is prepared in accordance with suppliers’ recommendations and requirements of local authorities.

SETTING PAD SATURATION

  1. For units fitted with taps located in the water distribution system follow the below process.
  2. The evaporative unit must be installed, plumbed and float levelled as per Seeley International instructions. The airflow rate should be adjusted to meet specifications.
  3. Pre-set each of the adjustor/taps to the ½ open position and fit all pad frames into place.
  4. Start the unit fan on high speed and turn on the pumps. All pad frames should now be fitted such that water is flowing to each pad but is not subject to draw-off or carryover around the pad frames. Always check for signs of splashing on interior unit components.
  5. The filter pads on the operating unit must now be observed. Check the outside of the unit for signs that the pads are becoming damp. It may take a few minutes for dampness to appear.
  6. After 10 minutes check the running unit again. Take note of any pads that still have dry sections. Stop the unit, remove the filter pad/s that provides access to the respective adjuster/tap and open the flow adjuster/tap slightly for any pad(s) that were found to be dry. Never adjust the water flow rate with the unit running.
  7. If a pad has been found to be very wet, and in danger of flooding, then close the corresponding adjuster/tap a small amount and re-test.
  8. Continue these procedures until all the pads are just damp and no flooding is visible on the pads. Stop the unit and check for signs of water draw-off or carry-over inside the unit (ie. water droplets on pulleys, motor, bearings, scroll, impeller etc.) If carry-over has occurred then adjust (reduce) the water flow to the respective pad(s) and restart the unit.
  9. The aim is to have all the pads suitably damp but not flooded.
  10. Continue this procedure until suitable wetting has been achieved.

Notes:

  1. The filter pad evaporation rate changes with entering air (ambient) conditions. The water flow rate should be set with this in mind and may have to be readjusted later due to seasonal weather changes.

  2. When performing scheduled maintenance it is recommended that the flow rate for each pump should be checked. c). The electrical current flow to the fan motor should be verified to ensure that it falls within the rating specified on the
    fan motor nameplate

  3.  Excessive airflow can cause water carryover by increasing the pad’s face velocity. Airflow should remain within the maximums specified for the unit.

  4. Filter pads with obstructed or blocked passages are more prone to water carryover. Blocked pads may have to be replaced if the blockage cannot be cleaned out. Otherwise, the water flow/airflow may be temporarily reduced to compensate. This will result in reduced capacity.

  5. As pads age they can accumulate unmovable dirt and accumulations. This may reduce the water flow rate the pad is able to handle without producing water carryover.

  6. Whenever the unit’s water bleed rate has been adjusted the water flow to the pads should be rechecked.

  7. Pads may require a period of operation for them to fully function correctly (Approx 3 weeks continuous operation depending on water quality).

Avoid Flooded Pads!

  • If the water flow rate to the filter pads is too high water draw-off or carryover will occur, often resulting in unit damage and premature component failures. In some cases water droplets can be sucked into the blower/fan wheel scroll and blown down the attached dropper or duct system.
  • When commissioning or servicing the unit look for tell-tale signs of flooded pads such as water washed bearings, rust on the dropper/plenum, water stains on the sides of the blower housing, fan scroll, and on the dropper/plenum. Over time water carryover will result in premature bearing failures, excessive corrosion, and damage to electrical components in the unit.
  • Damage due to water carryover is not covered by warranty.

COMMISSIONING RESULTS
All commissioning results should be recorded with a copy to be stored in the control box for reference during maintenance.

MAJOR SERVICE/COMPONENT REPLACEMENT PROCESS

Electrical Components
Electrical Wiring
The electrical wiring of the unit should be visually inspected every 6 months and pre-season to ensure that it is free from damage. If visible damage is noted, all damaged wiring should be replaced with reference to the wiring diagrams found in Appendix A.

The following are the recommended steps for replacing damaged electrical wiring.

  1. Electrically isolate unit
  2. Remove control box cover
  3. Inspect electrical wiring for damage
  4. Remove damaged wiring and replace.
  5. Replace control box cover and test unit operation

Isolator Fitted and Operational
Check that the isolator is present and free from damage. Isolate unit and confirm that power is not available at the unit.

Single or 3 Phase Power Test
A qualified electrician is to test the incoming power supply to the unit. The supply is to be tagged with available voltage and date of test.

Fan and Motor

  • Motors range in weight from approximately 15 to 30Kg’s. Generally the larger the unit the larger the motor. Refer to technical data sheet or contact Seeley International with the units serial number to identify which motor you have. The use of a lifting apparatus and/or several service personnel may be required for heaver motors.
  • Tools Required: Metric open end ring spanner set, Drive belt tensioning gauge, Pry bar or lever bar, ½” Socket set, metric hex key set, nylon hammer
  1. Electrically isolate unit.
  2. Disconnect Blower motor.
  3. Loosen motor platform and jacking bolts if fitted.
  4. Slacken and remove drive belt/s.
  5. Extend motor platform fully to gain access to motor mount bolts.
  6. Removed motor mount nuts/bolts (The rear bolts may remain in place).
  7. Check motor weight on name plate and use appropriate lifting equipment if necessary.
  8. Remove motor.
  9. Replace motor in reverse order.
  10. To tighten belts, use prybar to assist in lifting motor into place whist tightening locking bolts. Larger motors will have jacking bolts in the motor platform to hold the weight of the motor. Adjust these to the required length to achieve correct belt tension.

Note:

  1. Bolt tensions should be in accordance with bolt manufacturer’s recommendations for the bolt diameter, thread type and material. All mount bolts should be high tensile and a minimum grade of 8.8. Anti-seize should be used on all stainless steel bolts.
  2. Belt Tensioner recommended when replacing/re-installing belts.

Belts

  • Replacement of drive belts needs to be conducted routinely. The frequency of replacement will be determined by hours of operation, operational environment and previous maintenance schedule. Belts should be visually inspected monthly with a thorough inspection every 3rd month.
  • Tools Required: Metric open-end ring spanner set, Drive belt tensioning gauge, Pry bar or lever bar and ½” Socket set.
  • The following are the recommended steps to replace the drive belts. Before works commence ensure all spare parts ordered match that of the unit they are replacing. units are often custom specified for each application and may have components which differ from the standard product offering.
  1. Electrically isolate unit.
  2. Remove Blower Box access panels.
  3. Loosen motor platform bolts.
  4. Slacken and remove drive belt/s.
  5. Check Pulleys for excess wear, replace if necessary.
  6. Replace Belt/s. For multiple drive belt units ensure that they are a matched set. Belts from different suppliers and different batch lots will differ in length.

Pulleys

  • Pulleys are manufactured from steel or aluminium and will generally require replacement less than the drive belts. Any wear on the pulleys will shorten the drive belt life, therefore should be replaced if there are any signs of wear.
  • Tools Required: Metric open end ring spanner set, Drive belt tensioning gauge, Pry bar or lever bar, ½” Socket set, metric hex key set, nylon hammer.
  1. Electrically isolate unit
  2. Remove Blower Box access panels
  3. Loosen motor platform to scroll nuts
  4. Slacken and remove drive belt/s
  5. Remove Pulley/s from Taperlock bush. A taper lock bush is used to secure the pulleys to the drive shaft. If unsure on how to remove the taper lock bushes refer to the Fenner brand bush guide. Alternately contact Seeley International for Service assistance.
  6. Remove Taperlock bush from shaft, may require gentle tapping with nylon hammer.
  7. Remove Pulley/s.
  8. To reinstall pulley complete operation in reverse.

Note:

  1. The same diameter and belt designation must be used to ensure correct operation. Failure to do so will result in poor unit performance. It may also cause the drive motor to overamp.
  2. Bolt tensions should be in accordance with bolt manufacturer’s recommendations for the bolt diameter, thread type and material. All mount bolts should be high tensile and a minimum grade of 8.8. Anti-seize should be used on all stainless steel bolts.
  3. Belt Tensioner recommended when replacing/reinstalling belts.
  4. This is ONLY applicable to units with a Seeley supplied blower box. 3rd Party blowers will have their own maintenance schedule.

Fan Direction
Check that the fan is blowing in the right direction. If the fan is running in reverse change check the wiring diagram and swap the power to the motor.

Water Components

  1. Water Controls
    Confirm that the incoming water supply isolation valve is operational. If the isolation valve is in a location accessible by the public ensure that the valve can be locked open and closed.

  2. Water Connection Visual Inspection
    The incoming water supply is to be visually inspected for damage and leaks. If visual damage is evident the supply is to be isolated and location of the leak to be identified and fixed.

  3. Water Isolation Fitted and in Good Working Condition
    The water isolation ball valve is to be examined to make sure that it is present and in good working condition.

  4. Water Supply Pressure
    The water supply pressure is to be read at the entry to the unit and recorded.

  5. Float Valve Operation
    Check that the float valve allows for water to enter the reservoir and is set so that flow stops when the water level is 5 – 10mm below the overflow. Adjust if necessary.

  6. Overflow and Drainage
    Push the float valve down allowing excessive water into the reservoir until water flows into the overflow drain. Confirm the drain takes away all excess water.

  7. Automatic Drain Valve
    Refer to Automatic Drain Manual and confirm operation.

  8. Bleed Valve
    Confirm that the bleed valve is set to the correct rate. Refer to Table 3: Bleed Off Rate.Note:- Formation of salt deposit in cooler pads indicates insufficient bleed off. If there are white deposits in the pads or tank the bleed rate needs to be increased.

  9. Cooling Pads

  10. The cooling pads should be periodically cleaned. Once the pads have been removed from the unit they can be cleaned using a spray nozzle on a garden hose with a moderate pressure. Do not use a high-pressure hose. At this time the cooler cabinet should be inspected and cleaned.

  11. Cooling pads should be periodically changed, the frequency being determined by the rapidity with which dirt, alkali and other foreign matter accumulates in the pads to the extent that cooling efficiency is impaired. The need for changing pads will vary with the locality. If in very good condition, pads may be washed to clean away dust etc, but if pads appear aged or badly fouled, then replace. In localities where there is an excess of lime and alkali, the reservoir pan should be cleaned out every 60 days. If the water is all re-circulated this clean out must be done more frequently. This will also remove dirt which has been washed out of the filter pads.

Casing Components

  1. Weatherproof Casing Condition
    Check the weatherproof casing for signs of damage, corrosion and leaks. If corrosion is present take preventative action which may require components to be replaced. Timely action will reduce the likelyhood of the entire cooler being replaced.

  2. Water Carry Over
    As pads become blocked the open area decreases consequently increasing air velocity across the pads which leads to excessive water carry over from the pads onto the internal components. The effect can lead to premature bearing failure and corrosion within the unit and ductwork. Pads are to be cleaned and/or replaced and confirm saturation rate of pads.

  3. Duct Condition
    Visually inspect the ductwork connection into the unit for damage. When the unit is operating inspect the ductwork for leaks where visible. If ductwork is leaking, cracked the required airflow may not reach the area being serviced by the unit.

  4. General Installation
    Visually inspect the mounting and how the unit is secured to the roof/ground. Ensure that the unit is stable and correctly aligned with the ductwork.

  5. Access to Unit
    Check that access to the unit is free of obstructions. If the unit is located on a roof and an anchor system and harness are certified and maintained by an appropriately qualified individual.

  6. Maintenance Records
    Ensure that maintenance records are up to date and stored in a location where they are protected from the weather and other possible causes of damage. It is recommended to make multiple copies of Appendix C maintenance records. Failure to provide adequate service records will void product warranty.

  1. If during the first one (1) year from the date of purchase, the Goods upon examination prove defective by reason of improper workmanship or material, We will repair or replace at our option, the Goods or any part thereof without charge for either parts or labour during normal working hours.

Should we deem in our absolute discretion to replace the Goods pursuant to clause 1, we may substitute any similar good even if it is not on our current price/equipment list. Further, Goods presented for repair may be replaced by refurbished goods of the same type rather than being repaired. Refurbished parts may be used to repair the Goods.
