(see table 1).
1.
When installing or relocating the unit, be sure to keep the refrigerant circuit free from air or substances other than the
specified refrigerant.
—
Any presence of air or other foreign substance in the refrigerant circuit will cause system pressure rise or compressor rupture,
resulting in injury.
2.
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.
3.
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.
4.
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.
5
.
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.
6
.
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.
7
.
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.
8
.
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.
WARNING
To ensure safety, please be mindful of the following precautions.
5.1.6 Installation prepare
Please notice that the unit is filled with flammable gas R32. Inappropriate treatment of the unit involves
the risk of severe damages of people andmaterial. Details to this refrigerant are found in chapter
"refrigerant".
