(2). Unscrew and remove cap from service valve.

(3). Connect vacuum pump flexible hose to the service valve.

(4). Start vacuum pump for 10-15 minutes until it reaches an absolute vacuum of 10 mm Hg.

(5). With vacuum pump still running close the low pressure knob on vacuum pump manifold. Then stop

vacuum pump.

(6). Open 2-way valve 1/4 turn, then close it after 10 seconds. Check tightness of all joints using liquid

NOTES:

• Please read this manual carefully before installing and using the appliance;

• Do not let air enter the refrigeration system or discharge refrigerant when moving the air conditioner;

• Check the connecting cables and pipes carefully, make sure they are correct and firm before connecting

the power of the air conditioner;

• Test-run the air conditioner after finishing installation and record details of operation;

• Type of fuse used on indoor unit: 3.15/250V;

• For 9k,12k,18k models, fuse of outdoor unit: 15A/250V;

• The fuse for the whole unit is to be provided by the user according to the current at maximum power;

• Input or use other over-current protective device instead;

• Only the air conditioner can be connected to the power line;

• The power connection for the air conditioner has to be done at the main power distribution which has

to be of a low impedance;

• In order to ensure the suitability of the equipment for connection, the user should consult with the

supply authority, if necessary, that the service current capacity at the interface point is sufficient for the

equipment;

• Refer to the rating plate of the equipment for power consumption details;

• Risk of electric shock can cause injury or death: Disconnect all Remote electric power supplies before

servicing;

• When charging refrigerant into the system, make sure to change in liquid state, if refrigerant of the

appliance is R410a. Otherwise, chemical composition of refrigerant (R410a) inside the system may

change and thus affect performance of the air conditioner;

• According to the character of refrigerant (R410a), the pressure of the tube is very high, so be sure to

careful when you install and repair the appliance;

• If the supply cord is damaged, it must be replaced by the manufacturers After-Sales Service

or a qualified technician in order to avoid a hazard;

• The air conditioner must be installed by professional engineer.
