Refrigerant R 4044 itself is not explosive or poisonous However when exposed to high temperatures open flames R 404A can be decomposed to form hydrofluoric acid and carbonyl fluoride both of which are hazardous Always recover the refrigerant and store it in an approved container Do not discharge the refrigerant into the atmosphere Do not use silver alloy or copper alloy containing Arsenic Do not use R 404A as a mixture with pressurized air for leak testing Refrigerant leaks can be detected by charging the unit with a little refrigerant raising the pressure with nitrogen and using an electronic leak detector Note All brazing connections inside the Evaporator Case are clear paint coated Sandpaper the brazing connections before debrazing the components Use a good abrasive cloth to remove coating 90 3 REMOVAL AND REPLACEMENT COMPRESSOR IMPORTANT Always install a new Drier every time the sealed refrigeration system is opened Do not replace the Drier until after all other repair or replacement has been made Note When replacing a Compressor with a defective winding be sure to install the new Start Capacitor and Start Relay supplied with the replacement Compressor Due to the ability of the POE oil in the compressor to absorb moisture quickly the Compressor must not be opened more than 15 minutes for replacement or service Do not mix lubricants of different compressors even if both are charged with R 404A ex
