Safety and User Information C5-12 Controls 2 Safety and User Information The C5-12 controller and control strategy has been designed in accordance with stateof-the-art technological and engineering standards as well as in conformity with the recognized safety regulations. It must be used in an appropriate manner for suitable purposes, following the details contained within this manual and taking account of safety aspects and potential hazards. Failure to follow the instructions in this manual may result in danger to health and safety, damage to materials and incorrect unit operation. Information within this document advises on, but is not limited to, potential threats or concerns related to health and safety. All users must be, or employ, a trained professional to, assess issues relating to health and safety, before any use. 2.1 Availability of the operation manual This manual must always be available at the site where unit is operating. Every person working on the equipment must read this manual fully before commencing the work and take note of all relevant information while performing a task. The manual is intended for end users along with service and commissioning engineers. 2.2 Scope of the operation manual THIS IS AN ORIGINAL OPERATION MANUAL VERIFIED BY THE MANUFACTURER.

C5-12 Controls Safety and User Information 2.4 Safety-conscious working The following is initial general advice to consider during various stages of a project. More information can be found in the relevant Operation Manual for the product design. 2.4.1 At all times Filters (especially used or dirty filters) are easily flammable. Leaking refrigerant can catch fire and emit noxious substances. No smoking is allowed in direct proximity of any aspect of the Multi-DENCO system. No open flames near the system. 2.4.2 Whenever opening/removing any panel/grille/door You must wear suitable Personal Protective Equipment (PPE) at any point working with a unit from the DENCO Products range. As a minimum we recommend: Wear safety footwear Wear eye protection Wear protective gloves Wear protective clothing If operating for a prolonged period of time, noise reducing ear protection may be required. Always conduct your own personal risk assessment to evaluate any further requirements. 2.4.3 When unit is operational At any time the unit is operational, rotating machinery and electrically charged components are present. When the unit is not electrically isolated: Ensure all guards and doors are closed. Only remove guards or open doors: When the unit has been electrically isolated. Sufficient time has been allowed for the rotating fan momentum to cease. Sufficient time has been allowed for inverter circuits to discharge. 2.5 Modifications and changes Modification to the C5-12 control or display software, language, programming or design is not permitted and will invalidate warranty. Any requests for modifications, after the unit has been installed must be made through your local or regional office. FläktGroup DC-2016-0110-GB 2018-05/R1 Subject to modifications 9

Safety and User Information C5-12 Controls 2.6 Personnel selection and qualification Any individual working on the unit must read and understand all of this manual before starting any works. Any individual working on this system shall be suitably qualified and licensed for the region that the system in installed within. All personnel involved with the system must understand and observe any local legislation regarding safe working practice. 2.7 Closing down procedure It is essential for starting, closing down, emergency operation and fault finding to know the location of the following components: Location of isolator for power distribution to the unit Main Isolator (integral to unit or local position) ON/OFF icon on the display of the unit All valves likely to affect water supply to humidifier (if fitted) NOTE! The units are designed for continuous operation and it is recommended that the system is kept running overnight and at weekends to maintain stable room conditions. Short periods Long periods Indefinitely Should you require the equipment to be closed down for the weekend or Bank Holidays, no special precautions are required. Each unit may simply be turned off by pressing the On/Off icon. Alternatively, the "On/Off Times" can be configured in the controller software. If the plant is to be shut down for longer periods (up to a month) this can be done by switching off at the on/off icon, then opening the Main Isolator, and closing the local mains water supply to the humidifier. When re-starting the plant, follow the same instructions but in the reverse order. When the equipment is to be taken out of service for an indefinite period we recommend a qualified air conditioning engineer. An engineer will also be required for the restarting of the equipment. For units fitted with chilled water cooling and/or hot water heating, the mains power should remain "ON" for at least the stroke time of the valve actuator to ensure that the valve closes fully. 10 FläktGroup DC-2016-0110-GB 2018-05/R1 Subject to modifications
