1. Important Environmental Concerns Scientific research has shown that certain man made chemicals can affect the earth s naturally occurring stratospheric ozone layer when released to the atmosphere In particular several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine Fluorine and Carbon CFCs and those containing Hydrogen Chlorine Fluorine and Carbon HCFCs Not all refrigerants containing these compounds have the same potential impact to the environment Trane advocates the responsible handling of all refrigerants including industry replacements for CFCs such as HCFCs and HFCs Responsible Refrigerant Practices Trane believes that responsible refrigerant practices are important to the environment our customers and the air conditioning industry All technicians who handle refrigerants must be certified The Federal Clean Air Act Section 608 sets forth the requirements for handling reclaiming recovering and recycling of certain refrigerants and the equipmentthat is used in these service procedures In addition some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants Know the applicable laws and follow them WARNING Personal Protective Equipment PPE Required Installing servicing this unit could result in exposure to electrical mechanical and chemical hazards e Before installing servicing2. a re ignition cycle is initiated by the ignition control Check the operation of the gas ignition system 5 Check the burner manifold pressure A 1 8 inch pipe plug is provided in the gas valve for this purpose General information 10 Visually inspect all of the unit s flue product passage ways for excessive deposit build up and corrosion If build up or corrosion is apparent perform the necessary repairs Arrange for a qualified serviceman to inspect the unit every other heating season to maintain safe and efficient operation Visually check the main burner flames They should be bright blue flames extending into the heat exchanger sections Never store anything flammable or combustible around or near the unit RT SVU03D EN Literature Order Number RT SVU03D EN Date July 2009 Supersedes RT SVU03C EN May 2007 The manufacturer has a policy of continuous product and product data improvement and reserves the right to change design and specifications without notice Only qualified technicians should perform the installation and servicing of equipment referred to in this literature
