To ensure safety, please be mindful of the following precautions.

Warning

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.

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.

Safety precautions for installing and relocating the unit

1. There should be no obstruction near air inlet and air outlet.

2. Select a location where the condensation water can be dispersed easily and

won't affect other people.

3. Select a location which is convenient to connect the outdoor unit and near the

power socket.

4. Select a location which is out of reach for children.

5. The location should be able to withstand the weight of indoor unit and won't

increase noise and vibration.

6. The appliance must be installed 2.5m above oor.

7. Don't install the indoor unit right above the electric appliance.

8. Please try your best to keep way from uorescent lamp.

service agent or similarly qualied persons in order to avoid a hazard.

8. The temperature of refrigerant circuit will be high, please keep the interconnec-

tion cable away from the copper tube.

9. The appliance shall be installed in accordance with national wiring regulations.

10.Installation must be performed in accordance with the requirement of NEC

and CEC by authorized personnel only

1. The air conditioner is the rst class electric appliance. It must be properly

2. The yellow-green wire in air conditioner is grounding wire, which can't be used

for other purposes.

3. The grounding resistance should comply with national electric safety regulations.

4. The appliance must be positioned so that the plug is accessible.

5. An all-pole disconnection switch having a contact separation of at least 3mm in

all poles should be connected in xed wiring. For models with a power plug,

1. Preparation of test operation

● The client approves the air conditioner.

● Specify the important notes for air conditioner to the client.

2. Method of test operation

● Put through the power, press ON/OFF button on the remote controller to start

operation.

● Press MODE button to select AUTO, COOL, DRY, FAN and HEAT to check

whether the operation is normal or not.

● If the ambient temperature is lower than 16

℃(61°F)

, the air conditioner can’t

start cooling.

1. Standard length of connection pipe

● 5m, 7.5m, 8m.

4. The additional refrigerant oil and refrigerant charging required after prolonging

connection pipe

● After the length of connection pipe is prolonged for 10m at the basis of

standard length, you should add 5ml of refrigerant oil for each additional 5m

of connection pipe.

● The calculation method of additional refrigerant charging amount (on the basis

of liquid pipe):

● Basing on the length of standard pipe, add refrigerant according to the

requirement as shown in the table. The additional refrigerant charging amount

per meter is different according to the diameter of liquid pipe. See the

following sheet.

Additional refrigerant charging amount = prolonged length of liquid pipe ×

additional refrigerant charging amount per meter
