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 National 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. INSTALLER AND MAINTENANCE CONTRACTORS 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 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 pan (Reservoir) 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/ wildfire construction requirements.

If the roof is structurally inadequate, provide an alternate load bearing structure. The ideal location for the cooler is in a central position on the roof (away from sleeping areas and where people spend most of their time) so that the duct runs are of approximately the same length. Carefully consider neighbouring residences and noise levels when locating the cooler, if necessary talk to the customer and the neighbour before carrying out the installation. Always locate the cooler where it will receive adequate fresh air and not in a recess where it may be starved for air or where the air is polluted. Ensure location is a minimum of: · 10' (3m) from a solid fuel heater flue, · 5' (1.5m) from a gas flue, · 17' (5m) from a sewer vent, and · 2' (600mm) from a wall. The cooler must be mounted at least 10' (3m), preferably 17' (5m), away from any TV antenna or antenna cables. EXQ MODELS SOLENOID COVER CONTROL CABLE CABLE TIE E FLEXIBLE HOSE ASSEMBLY X RUBBER WASHER NUT ½"BSP & OLIVE ILL1204-C Make sure the cooler is not between the antenna and the transmission tower that is providing the television signal to the home. Allow adequate access to and around the cooler for maintenance. Provision must be made for access to electricity, water supplies and drains. Note! Do you need to discuss the installation of items like safety anchor points with the customer? ACCESS FOR SERVICING AND MAINTENANCE BRASS ADAPTOR ½"BSP to 1/4" COMPRESSION ILL3385-A The cooler should be installed in a position that allows adequate access for installation, and future maintenance and servicing activities.

ALL COOLERS 3.5' (1.0m) ILL2645-B Extra service or warranty charges may aILpLp26l4y5-Bfor the cost of any equipment or additional labour involved in accessing the cooler if these guidelines are not met. INSTALLING THE ROOF JACK New Installation Use 24G or stronger metal roof jack. The cooler may then be attached directly to the jack. Replacement Installation Roof Jack recommended wall thickness should be 24G or stronger. The supplied roof jack adaptor may be required to attach the cooler to the existing roof jack. To assemble the roof jack adaptor, hold panels at 90 degrees to one another. Align slots in upper and lower panels then slide together. ILL1667-A Do not slide the cooler, lift and carry it. It is recommended that at least 2 people carry the cooler whenever it needs to be moved. Do not drop the cooler. Always handle with care. Important! For lifting or pulling purposes when using ropes or slings, always apply the ropes around fan housing. Never tie them to any or all of the 4 round corner posts. WARNING! Take care that the ends of ladders, etc. don't penetrate into the opening of the cooler, as the Weatherseal or the cut-off plate may be damaged. CAUTION! Never try to raise the cooler to the roof alone. MOUNTING THE COOLER Locate the cooler on the dropper with the pan (reservoir) sump on the low (gutter) side of the installation. ILL3363-A Note! It is recommended that a strip of foam or sealant is ILL3363-A applied to the upper flange on the roof jack before securing the cooler to provide an airtight seal. Ensure that the top of the roof jack is level and square in all directions (use a spirit level). This helps with levelling the cooler. ILL159-F Fix the cooler to the dropper with 8 self-tapping screws provided (2 screws per side). There are ten screw locations identified by "V" notches. If access to the "high roof side" is limited, use 3 screws on each side and 2 on the front. In exposed or high wind areas, seek advice from a structural engineer. Important! Screw length must be less than 1.5" (40mm) to avoid interfering with the weatherseal. ILL922-B BREEZAIR EXQ EVAPORATIVE COOLER INSTALLATION MANUAL | 5 INSTALLATION SECURING THE LEG SUPPORTS The telescopic leg supports (with feet attached) slide up and down inside the four corner posts. By removing the screw from the lower end of the corner post you enable the leg support to slide down to roof level. WEATHERSEAL AND LATCH (Model dependant, refer to Dealer.) Where fitted, the Weatherseal latch performs two functions. In the locked position it acts as a latch, preventing movement during transport. LOCKED POSITION ILL958-A Make sure each leg is vertical before securing. Secure foot to roof with 2 screws (minimum). ILL958-A OPERATING POSITION ILL1649-A In the operating position it acts as a restrainer, preventing gusts of wind from opening the Weatherseal. Once the cooler is installed on the roof, squeeze the latch and rotate it clockwise to its operating position. ILL959-B Maintain downward pressure on corner post as you replace the screw to ensure that the bottom of the corneILr Lp9o5s9t-Bis sitting flush with base of corner support (view through "V" notch). Ensure screw is horizontal when replaced. ILL1650-A Check the Weatherseal moves freely and without obstruction by lifting the latch and rotating counterweighted arm.

Cable glands are provided for ½" ID conduit. MAIN POWER BLACK/BROWN GREEN/YELLOW WHITE/BLUE gn/y T1 T2 T3 COOLER ENCLOSURE INSTALLER SUPPLIED ALL-POLE DISCONNECT SWITCH JUNCTION BOX L1 L2 (USA) MAIN POWER SUPPLY L N (EUROPE) ILL1898-A Installation of the cooler must conform to local electrical rules, regulations and standards. Important! It is a requirement of Seeley International that all Breezair coolers be connected to a dedicated circuit to the distribution board, with a separate circuit breaker and incorporate all pole disconnection switch in accordance with the local wiring rules. Electrical supply specifications may vary depending on model or region. Please refer to the rating label attacheILdLt1o8t9h8e-cAooler for details. WARNING! If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or a similarly qualified person in order to avoid a hazard. INSTALLING THE MAINS POWER CABLE This cooler contains an electronics module (control box) with main power supply termination box separated and connected via a cable and plug assembly. The point of entry into the cabinet of the cooler is by knockouts in the pan (reservoir). Seal the gap between the conduit and the knock-out hole with silicone sealant after making connections and clamping the conduit cable. Important! Ensure that all electrical connections are tight. Loose connections will cause overheating that may lead to machine damage or fire. Replace all covers on completion of work, using only the screws supplied. Do not tamper with factory wiring. Before leaving the job, a trained, licensed technician must check that the cooler is operating correctly. CONTROL BOX ILL1395-A Terminate the power cable outside of the cooler in a junction box installed nearby. Refer to the field wiring diagram in the previous section. The fixed wiring must be The fixed wiring must be fitted with an all pole disconnection switch that ILL1395-A breaks the active (hot) and neutral (common) in accordance with local wiring rules. It is recommended that the junction box be located and installed on the dropper (roof jack). IMPORTANT REMINDER! Do not route extra-low voltage data/communication and low voltage supply mains cables without first consulting your local wiring standards. Routing data/communication cables and supply mains cables in close proximity can present an electrical hazard and can be detrimental to the performance of the product, resulting in intermittent communication errors, locking up of screens, displays dropping out and inconsistent erratic operation. INSTALLING THE CONTROLLER CABLE Seeley International recommends: · Not routing data/communication and supply mains voltage cables in the same conduit. · Not cable tying or taping data/communication and supply mains voltage cables together. · A minimum separation distance, as specified by your local wiring standards, between data/communication and supply mains cables. In Australia, this minimum separation distance is 2" (50mm). Connect one end of the control cable (with ferrite suppressor) to the cooler electronics box. ILL2149-A Your cooler electronics will have 2 x RJ ports as shown above. For cooler electronics with 2 x RJ ports, the wall control cable can be fitted to either. BREEZAIR EXQ EVAPORATIVE COOLER INSTALLATION MANUAL |IL7L2149-A INSTALLATION INSTALLING THE CONTROLLER CABLE Run the cable to the roof space and then to the controller via the mains power cable entry point and plug in to the rear of the wall control. Note! The maximum length for the wall control cable to travel alongside the power cable is 33' (10m). WARNING! Do not let the cable, the cable ends, or the control box get wet. Position the cable in the dropper so they will be accessible from inside the roof space. INSTALLING THE INLET SOLENOID For coolers fitted with a drain and solenoid valve, it is a requirement to fit the new detachable hose set as supplied. Any old hose sets should not be re-used. For EXQ model coolers, fit the inlet solenoid under the pan (reservoir) as shown: A I WATER REQUIREMENTS Installation of the cooler water supply must conform to local plumbing rules, regulations and standards. The following specifications for the cooler water supply are required: Water Connection ½" BSP Min Water Pressure 15psi (100kPa) Max Water Pressure 115psi (800kPa) Min Water Flow 2.1 gallons/min (8 liters/min) Max Water Temperature 104°F (40°C) Important! If the water pressure exceeds maximum specification then a pressure reducing valve is required and must be supplied and fitted by the installer. WATER CONNECTIONS A permanent water supply is required to be connected to the cooler. The water connection point is located on the underside of the cooler pan (reservoir). You must install 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. COOLERS WITH DRAIN VALVES For coolers with the inlet solenoid valve fitted, the water connection is a 1/2" BSP compression fitting on the end of a flexible hose. The flexible hose is connected to the float valve. The 1/2" BSP Compression fitting can be directly screwed onto the water pipe or be directly screwed onto the manual water shut-off valve. Always ensure that the water pipe connection does not place sideways strain onto the float valve. Important! In areas subject to freezing, the water supply line to the cooler requires a drain down facility at the lowest point in the water supply pipe. Important! Flush the water pipe to remove any swarf before final fitting. Swarf can lodge in the solenoid and float valve, preventing them from functioning correctly.

Tighten the solenoid valve until it seals against the rubber washer and is in the orientation shown such that the solenoid cover will clip on over the top. The water solenoid is required to be installed in the direction of flow as per the arrow indicator on the solenoid. ILL1676-A Ensure washers are correctly located. Do not over tighten plastic fittings. Insert the solenoid cable through the hole in the cooler pan (reservoir) (behind the drain valve) and connect to the water solenoid valve. Make sure the cable is fitted to the groove underneath the pan so it does not get trapped by the solenoid cover when fitted. The cable leads can be connected to the solenoid either way around. Important! The cable must wrap underneath the solenoid. 8 | INSTALLATION FITTING THE SOLENOID COVER CONNECTING THE MAGIQTOUCH CONTROLLER Once the solenoid valve and its cable has been fitted, place the cover over the assembly. Make sure the solenoid valve cable is retained in the groove in the cooler pan (reservoir). Secure the cover by tightening the flexible hose assembly nut (C). Important! Make sure the cable cannot lay in the water at any stage. Connect the electrical leads to the solenoid. The electrical cable leads may be connected to the solenoid either way around. Taps or shutoff valves used must not be of the non - return type. Water drained from the cooler must be carried away to a suitable discharge point in accordance with local regulations. INSTALLING THE DRAIN VALVE Water drained from the cooler must be carried away to a suitable discharge point in accordance with local regulations. Important! Never drain water from the cooler directly on to the roof. DRAIN VALVE ASSEMBLY Assemble the drain valve as shown: Refer to the installation manual provided with the wall controller for instructions on installing the controller. Coolers are supplied with a 66' (20m) control cable. Longer cable lengths are available from Seeley. Important!
