• Any maintenance and/or installation shall be

performed by distributors or licensed and qualified

individual.

• Electrical work MUST be performed by licensed

technician according to local regulations and the

instructions given in this manual.

• Use extreme caution when performing electrical

installation tasks – Electric shock can result in

severe injury or death.

WARNINGS!

1. Disconnect power supply prior to ANY work.

2. The air conditioner is a specialized circuit that

requires its own power supply – this is not to be

shared with ANY other electrical appliances.

3. The air conditioner should be installed in a suitable

location and the power supply should be easily

reachable by ALL users.

4. During maintenance and installation, make sure

wiring terminals are securely fastened.

5. Ground wire MUST be firmly connected and NOT

used for other purposes.

6. Use protective accessories as necessary, (IE:

protective boards, cable-cross loop, wire clips, etc.).

7. Live wire, neutral wire, and ground wire MUST

correspond to the live wire, neutral wire, and ground

wire of the air conditioner.

8. Power cord and power connections MUST be free

of obstruction and CANNOT be compressed.

9. Should power cord or power connection become

severed, they MUST be repaired/replaced by

qualified technician.

10. If the power cord or power connection wire is not

long enough, replace with specialized cable from

manufacturer before proceeding with installation or

repair. DO NOT elongate these wires.

11. An air switch MUST be installed if there is no plug

found on the air conditioner. The air switch MUST

be all-pole parting and the contact parting distance

MUST be at 1/8” or greater.

12. All wires and pipes MUST be connected firmly prior

to supplying the unit with power.

13. Eliminate any electric leakage on the unit body.

14. Fuses MUST be replaced with fuse of the same

specification(s). DO NOT replace with copper wire

or conducting wire.

15. If the unit is being installed in a humid climate, a

6. Make sure to clear the unit of any/all foreign objects

prior to completion of installation.

REFRIGERANT SAFETY PRECAUTIONS

1. Avoid contact of fire and refrigerant as the

combination creates poisonous gas.

2. Use only specified refrigerant. DO NOT mix

refrigerant types. DO NOT allow air to remain in

refrigerant lines as this may lead to pipe rupture or

other hazards.

3. Check entire system for refrigerant leaks prior to

completing installation.

Technical Information 2

IF SAFETY PRECAUTIONS

FOR INSTALLING AND

RELOCATING THE UNIT:

WARNINGS!

1. When installing or relocating the unit, be sure to

keep the refrigerant circuit free from air and other

substances other than the specified refrigerant.

Presence of air or other foreign substance in the

refrigerant lines will cause the system pressure to

rise and could cause the compressor to rupture –

causing injury.

2. When installing or moving the unit, DO NOT charge

with refrigerant other than the specified type listed

on the nameplate of the unit.

This will cause abnormal operation, improper actions

and mechanical malfunction and may result in

serious injury.

3. Refrigerant recovery during relocation or repair:

Ensure unit is running in cooling mode. Fully close

valve at high pressure side (liquid valve). After 30

seconds, fully close valve at low pressure side (gas

valve). Immediately stop the unit and disconnect

power. Total time for refrigerant recovery should not

exceed 1 minute.

If refrigerant recovery takes too much time, air may

be sucked in causing the pressure to rise and the

compressor to rupture which can lead to severe

injury or death.

4. During refrigerant recovery, make sure the liquid and

gas lines are fully closed and power is disconnected

before detaching the connection pipe.

If the compressor starts running while stop valve is

open and connection pipe is not affixed, air will be

sucked in causing pressure to rise and potentially

causing compressor rupture which may lead to

severe injury or death.

5. When installing the unit, make sure the connection

pipe is securely connected before the compressor

starts running.

If the compressor starts running while stop valve is

open and connection pipe is not affixed, air will be

sucked in causing pressure to rise and potentially

causing compressor rupture which may lead to

severe injury or death.

6. DO NOT install the unit in an area exposed to (or

potentially exposed to) corrosive or flammable gas

leaks.

Leaking gas near the unit may cause fire or

explosion leading to property damage, severe injury

or death.

7. DO NOT use extension cords for electrical

connections. If the electrical wire in not long

enough, contact a local service authorized center to

install the proper length wiring.

Poor connections may lead to electrical shock or fire.

8. Use manufacturer specific wires for connections

between indoor and outdoor units. Firmly clamp

wires between indoor and outdoor units. Ensure

terminals receive NO external stress.

Electric wires with insufficient capacity, improper

connection points, and/or improperly secure

terminals may cause electric shock or fire.

• Connect charging hose of piezometer to the refrigerant

charging vent of the gas valve. Then connect the other

charging hose to the vacuum pump.

• Open piezometer completely and operate unit for 10-15

minutes in order to check pressure level of piezometer. Should

remain at -0.1MPa.

• Close vacuum pump and keep closed for 1-2 minutes to verify

pressure of piezometer remains at -0.1MPa. If the pressure

decreases, there MAY be leakage.

• Remove piezometer, completely open both the valve core of

the liquid valve and gas valve with an inner hexagon spanner.

• Tighten screw caps of valves and refrigerant charging vent

(Shown in Figure #28 below).

2. Leakage Detection

• Check for leaks using leak detector.

• Use soapy water if leak detector is unavailable. Apply soapy

water to the area in question. Leave soap & water solution on
