Any presence of air or other foreign substance in the refrigerant circuit will cause
system pressure rise or compressor rupture, resulting in injury.
When installing or moving this unit, do not charge the refrigerant which
is not comply with that on the nameplate or unqualified refrigerant.
Otherwise, it may cause abnormal operation, wrong action, mechanical
malfunction or even series safety accident.
When refrigerant needs to be recovered during relocating or repairing the
unit, be sure that the unit is running in cooling mode.Then, fully close the
valve at high pressure side (liquid valve).About 30-40 seconds later, fully
close the valve at low pressure side (gas valve), immediately stop the unit
and disconnect power. Please note that the time for refrigerant recovery
should not exceed 1 minute.
If refrigerant recovery takes too much time, air may be sucked in and cause
pressure rise or compressor rupture, resulting in injury.
During refrigerant recovery, make sure that liquid valve and gas valve are
fully closed and power is disconnected before detaching the connection pipe.
If compressor starts running when stop valve is open and connection pipe is not
yet connected, air will be sucked in and cause pressure rise or compressor
rupture, resulting in injury.
When installing the unit, make sure that connection pipe is securely
connected before the compressor starts running.
If compressor starts running when stop valve is open and connection pipe is not
yet connected, air will be sucked in and cause pressure rise or compressor
rupture, resulting in injury.
Prohibit installing the unit at the place where there may be leaked corrosive
gas or flammable gas.
If there leaked gas around the unit, it may cause explosion and other accidents.
Do not use extension cords for electrical connections. If the electric wire
is not long enough, please contact a local service center authorized
and ask for a proper electric wire.
Poor connections may lead to electric shock or fire.
Use the specified types of wires for electrical connections between the
indoor and outdoor units. Firmly clamp the wires so that their terminals
receive no external stresses.
Electric wires with insufficient capacity, wrong wire connections and insecure
wire terminals may cause electric shock or fire.

All the work men who are engaging in the refrigeration system should bear the
valid certification awarded by the authoritative organization and the qualification
for dealing with the refrigeration system recognized by this industry. If it needs
other technician to maintain and repair the appliance, they should be supervised
by the person who bears the qualification for using the flammable refrigerant.
It can only be repaired by the method suggested by the equipment’s manufacturer.

The refrigerant should be recycled into the specialized storage tank.
Make sure that there isn’t any naked flame near the outlet of the vacuum pump
and it’s well-ventilated.
Use the refrigerant filling appliances specialized for R32. Make sure that different
kinds of refrigerant won’t contaminate with each other.
After filling is finished, please do the leakage detection before test running; another
time of leak detection should be done when it’s removed.
Please use the flammable gas detector to check before unload and open the container.
No fire source and smoking.
According to the local rules and laws.
The refrigerant tank should be kept upright at the time of filling refrigerant.
Stick the label on the system after filling is finished (or haven’t finished).
Don’t overfilling.
