R-454B SEALED SYSTEM REPAIR General Information WARNING: Electrical Shock Hazard Disconnect all power to the unit before starting maintenance. All electrical connections and wiring MUST be installed by a qualiﬁed electrician and conform to all codes which have jurisdiction. Failure to do so can result in property damage, severe electrical shock or death.
Page 231 R-454B SEALED SYSTEM REPAIR General Information Warning: No ignition sources: No person carrying out work in relation to a REFRIGERATING SYSTEM which involves exposing any pipe work shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing and disposal, during which refrigerant can possibly be released to the surrounding space.
