Refrigerant under High Pressure!
Failure to follow instructions below could result in an
explosion which could result in death or serious
injury or equipment damage.
System contains refrigerant under high pressure.
Recover refrigerant to relieve pressure before
opening the system. See unit nameplate for
refrigerant type. Do not use non-approved

WARNING
Explosion Hazard!
Failure to follow instructions below could result in an
explosion which could result in death or serious
injury, and equipment damage.
NEVER bypass system safeties in order to pump
down the unit component's refrigerant into the
microchannel heat exchanger (MCHE) coil. Do NOT
depress the compressor contactor since it effectively
bypasses the high-pressure control.
