Page 4 Hydrocarbon INTRODUCTION ATTENTION Please read this manual carefully before installing and operating the GREE Hydrocarbon Air– Conditioner unit. Careless installation and operation could cause severe injuries to operators, workers and damage to the air-conditioner unit itself. Keep this manual in a location for easy access as it is needed for reference during installation, maintenance, service and operation of the unit.
Page 5 Notices General Safety Instructions Please pay careful attention to these safety instructions, to avoid risks to people and property. Before starting work on maintenance read this manual thoroughly and pay particular attention to the relevant chapters. Regardless of further requirements of the country, in which the equipment will be installed: assembly, first start up, technical service, maintenance and repair and as well as dismantling and disposal have to be carried out by authorised personnel only.
Page 6 Working on components with safety-relevant functions jeopardise the safe operation of the GREE (OEM) installation. In case it is necessary to replace components, only use approved parts from GREE spare-parts are Electric, the Original Equipment Manufacturer(OEM) or Gree released or authorised components.
Page 7 Basics in RAC Knowledge of the basic SI standard units for temperature, pressure, mass, density, energy. Understanding of the basic theory of refrigeration systems including the functions of the main components in the system (compressor, evaporator, condenser, thermostatic expansion valves). Understanding how to read a refrigerant flow chart and an electrical circuit diagram.
Page 8 HC R290 Refrigerant Lssues Please notice that the unit is filled with propane. Details to this refrigerant are found in chapter “refrigerant”. Propane is highly flammable and leads to explosion under certain conditions. Inappropriate treatment of the unit involves the risk of severe damages of people and material.
Page 9 Flammability Three components are needed simultaneously for causing fire: 1. Oxygen 2. Ignition source 3. The flammable concentration of HC For ignition, the concentration of HC in air has to be between the lower and upper flammable limits. If the concentration is below the lower flammability limit (LFL) of about 2% by volume in air, there is not enough HC for combustion.
Page 10 First Aid Measures Inhalation: Remove the affected person to fresh air. If breathing has stopped, administer artificial respiration. Give external cardiac massage if necessary. If the person is breathing but unconscious, place them in the recovery position. Obtain medical assistance immediately. Skin: In case of cold burns: flush with water to normalize temperature.
Page 11 DO NOT USE WATER JET Special protective equipment for fire fighters: In confined spaces use self-contained breathing apparatus Hazardous combustion products: Incomplete combustion may form carbon monoxide. Accidental Release Measures Immediate emergency action: Further actions: · Clear people away from the area to a safe place ·...
Page 12 The HC leak de- tector is indeed a Personal Protective Equipment (PPE) device! Sign plate to protect and mark the working area. Appropriate detectors, suitable for hydrocarbons, must be available and operational all the time. Appropriate tools and appliances must be available and ready for operation. Any employees need to be instructed extensively about the safety measures and the possible safety hazard.
