REFRIGERANT CHARGING WITH GAS
1. Remove two screws and access cover from air conditioner.
Use great care to avoid contact with liquid refrigerant or refrigerant
gas being discharged from any container under pressure. Sudden and
irreversible tissue damage can result from freezing. Wear thermal
protective gloves and a face protector or safety glasses in any situation
where skin or eye contact is possible.
Prevent contact of refrigerant gas with flame or hot metal surfaces.
Heat causes the refrigerant to breakdown and form carbonyl chloride
(phosgene), a highly toxic and corrosive gas. In case of refrigerant
leaks, ventilate area immediately.
Remove the valve cap from the low pressure (suction) service valve.
Position the refrigerant tank in an upright position close to the service valves.
