Installation prepare
To ensure the safety, please be mindful of the following precautions
WARNING
1. When installing or relocating the unit, be sure to keep the refrigerant circuit free from air or substances other than the
speci fi ed 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
unquali fi ed 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 speci fi ed 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.

center, the malfunction may not be solved due to incovenient contact between the user and the service personnel.
3. When removing the unit to the other place, please firstly contact with the local authorized service center.
4. Warning: Before obtaining access to terminals, all supply circuits must be disconnected.
5. For appliances with type Y attachment, the instructions shall contain the substance of the following. If the supply cord is
damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
6. The appliance must be positioned so that the plug is accessible.
7. The temperature of refrigerant line will be high; please keep the interconnection cable away from the copper tube.
8. The instructions shall state the substance of the following:This appliance is not intended for use by persons(including children)
with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance.
9. Appliance shall be installed, operated and stored in a room with a floor area larger than "X" m
2
(see table 2).
Please notice that the unit is filled with flammable gas R32. Inappropriate treatment of the unit involves
the risk of severe damages of people and material. Details to this refrigerant are found in chapter
"refrigerant".
