Warning and Safety
*Read this guide before installation. Failure to follow the safety instructions may result in property
damage, serious injury, or death.
• The air conditioner is pre-charged with R32 refrigerant. Handle the air conditioner with care
and check if there is any refrigerant leakage during installation. Refrigerants have no odor
and can be toxic and ammable. Rapid evaporation of refrigerant may cause frostbite,
cardiac arrhythmia, and/or irritation, as well as cause environmental damage.
• The room for the installation, use, repair, and/or storage of this air conditioner should be
greater than 5m².
• Do not charge air conditioner refrigerant more than 1.7kg.
• Stop valve cover must be installed on the air conditioner to prevent possible refrigerant
leaks.
• Refrigerant leakage or damaged pipeline must be inspected and repaired by a qualified
HVAC technician.
• Do not install or store this appliance in a room with continuously operating ignition sources
such as open flames, gas appliances, or electric heater
• Do not install the appliance within 50cm of ammable substances such as alcohol, etc. Or
pressurized containers such as spray cans.
• The appliance must be installed in accordance with applicable federal, state, and local
regulations.
• Ensure that the power supply voltage corresponds to that stamped on the rating plate.
• Do not bend, tug, or compress the power cord during installation to prevent damaging the
power cord. The electrical cord should be replaced by a qualied electrician.
• Do not use power extensions and/or muti-socket modules for appliance installation.
• Do not alter, change, or modify the appliance.
• A fuse or overload protection device with a suitable capacity for the indoor unit must be
installed.
• The appliance must be tted with means for disconnection from the main power supply
under over-voltage category III conditions. All electrical wiring must follow federal, state, and
local regulations.
• Do not place the appliance in contact with water. The electrical insulation could be damaged
and thus cause electric shock.
• When working on the electric terminals, make sure the appliance is disconnected from the
power supply.
• Make sure the appliance is properly grounded to prevent electric shock.
• Store the air conditioner in a safe location to prevent possible damage before installation.

Vacuum Pumping and Leak Test
1. Remove the protective cap from the service port, low-pressure valve, and high-pressure valve.
2. Connect the pressure hose from the manifold gauge to the service port.
3. Connect the charge hose from the manifold gauge to the vacuum pump.
4. OPEN the low-pressure valve (Lo·M) and CLOSE the high-pressure valve (Hi·M) on the manifold
gauge.
5. Turn on the vacuum pump to vacuum the system.
6. Let the vacuum pump run for at least 15 minutes and make sure the gauge indicates −0.1Mpa
(−76cmHg).
7. Close the pressure valve (Lo·M) and turn off the vacuum pump.
8. Leave the system connected with the manifold gauge for 5 minutes, then make sure the gauge
indication does not exceed 0.005Mpa.
* In the case of a leak, and the pressure value increases, reconnect all the connection joints on the
refrigerant line, and redo the vacuum pumping.
9. Open the high-pressure valve (Hi·R) for 1/4 turn, then close the valve after 5 seconds.
10. Check all the connection joints with a refrigerant leak detector or liquid leak detector.
11. Add refrigerant charge if you use a lengthened refrigerant line.
12. Disconnect the pressure hose from the service port, then fully open the low-pressure valve (Lo·R)
and high-pressure valve (Hi·R).
13. Put the protective caps back on the service port, low-pressure valve, and high-pressure valve.
Tighten the caps.
