Note: ensure the correct refrigerant gas is used to recharge the unit as an incorrect
gas can cause damage beyond repair to the compressor.
Do not use oxygen to purge lines or to pressurize a unit for any purpose.
Oxygen gas reacts violently with oil, grease and other common substances. Use only
refrigerant or dry nitrogen for testing.
Never exceed the specified maximum operating pressures.
Do not un-weld or flame cut the refrigerant lines including any refrigerant circuit
components until the entire refrigerant (liquid and vapour) has been removed from
unit. Traces of vapour should be displaced with dry nitrogen.
Refrigerant in contact with an open flame will produces toxic gases.
Ensure that the necessary safety protection equipment is available when servicing.
Have the appropriate fire extinguishers for that system.
Do not siphon refrigerant.
Avoid spilling liquid refrigerant onto the skin or splashing it into the eyes. Use safety
goggles. Wash any spills from the skin with soap and water. If liquid refrigerant enters
the eyes, immediately and abundantly flush the eyes with water and consult medical
advice.
Note: Never apply an open flame or live stream to a refrigerant container. This can
dangerously overpressure and cause an explosion.
