Below are listed three kinds of Safety Cautions and Suggestions.
WARNING!
CAUTION! Incorrect operations may result in injuries or machine damages; in some cases may
cause serious consequences.
Incorrect operations may result in severe consequences of death or serious injuries.
INSTRUCTIONS: These information can ensure the correct operation of the machine.
Be sure to conform with the following important Safety Cautions.
The Safety Cautions should be at hand so that they can be checked at any ti e when needed.
If the conditioner is transferred to the new user, this manual should be as well transferred to the
new user.
Safety Cautions
Carefully read the following infor ation in order to operate the airconditioner
correctly.
WARNING!
If any abnor al pheno ena is found
(e. g.s ell of firing), please cut off the
power supply i ediately, and contact
the dealer to find out the handling
ethod.
Don't dis antle the outlet of the
outdoor unit.
The exposure of fan is very dangerous
whichmay harm human beings.

In such case, to continue using the
conditioner will damage the conditioner,
and may cause electrical shock or fire
hazard.
Incorrect maintenance and repairment
may cause water leak, electrical shock
and fire hazard.
When need aintenance and repair ent,
call dealer to handle it.
After a long ti e use of air-conditioner
the base should be checked for any
da ages.
If the damaged base is not repaired, the
unit may fall down and cause accidents.

Air-conditioner can't be installed in
the environ ent with infla able
gases because the infla able gases
near to air-conditioner ay cause fire
hazard.
Connect earthing wire.
Use discharge pipe correctly to ensure
efficient discharge.
Earthing wire should not be con-
nected to the gas pipe, water pipe,
lightning rod or phone line, in-
correct earthing may cause shock.
Incorrect pipe use may cause water
leaking.

Place where the air outlet may not be exposed to a strong wind.
Place surrounded at four sides are not suitable for installation. A 1m or more
of overhead space is needed for the unit.
Mount guide-louvers to place where short-circuit is a possibility.
When installing several units, secure sufficient suction space to avoid short
circuiting.

In the first to third test steps, if the pressure drops, check the leakage in each joint
use sense of hearing, feeling and soap water, etc. methods to find the leaking point.
After confirming the leaking point, welding it again or tighten the nut tightly again.

over 3 minutes.
Second step: 1.5Mpa
(15kg/cm2g) pressurize
over 3 minutes. Large
leakage will be found.
Third step: 3.0 MPa
(30kg/cm2g) pressurize
about 24 hours. Little
leakage will be found.
After finishing connection of refrigerant pipe, it shall perform air tightness test.
The air tightness test adopts nitrogen tank to give pressure according to the pipe connection
mode as the following figure shown.
The gas and liquid valve are all in close state. In order to prevent the nitrogen entering the
circulation system of outdoor unit, tighten the valve rod before giving pressure (both gas
and liquid valve rods).

Installation Procedure
Refrigerant piping

It shall use the vacuum pump of (lower than -755mmHg)high vacuum degree and large air
discharging (over 40l/min).
The vacuumizing time depends on the length of the connecting pipe, generally is 1~2 hours.
When vacuumizing, it shall be confirmed both gas and liquid side valves are closed.
If after 2 hours vacuumizing, it cannot reach the vacuum degree below -755mmHg, it can be
vacuumized for other 1 hour.
If after 3 hours vacuumizing, it still cannot reach the vacuum degree below -755mmHg, check
if there is any leaking point and repair the them.
If after over 2 hours vacuumizing, the vacuum degree is below -755mmHg, close the VL
and VH on the meter separator and stop vacuumizing. 1 hour later to confirm if the vacuum
degree changes. If changes, it indicates there is leaking point in the system. Check the leaking
point and repair.
After finishing the above vacuumizing, change the vacuum pump into refrigerant pump to
charge the refrigerant.
se vacuum pump to perform vacuumizing. It is strictly forbidden to use the
refrigerant to remove the air inside the system.
After air tightness test and discharging all the nitrogen, connect the vacuum pump
as the following figure shown.

When the total length (L) of the two indoor units' connecting pipe is less than 5m, it is
unnecessary to charge additional refrigerant.
If the connecting pipe (L) exceeds 5m, it shall charge Mg additional refrigerant per meter.
That is: Refrigerant charging amount = (L-5) x M (g)
For A 122AEEAA,A 182AEEAA, M=30

Only in COOLING operation can charge the additional refrigerant.
When charging, the refrigerant shall be charged from the charging nozzle of low pressure vavle.
Be carefull when charging refrigerant, do not let the air mix into the system,and must charge the
additional refrigerant in liquid condition.

(1) Selection of size of power supply and interconnecting wires.
Precautions for Electric wiring
Electric wiring work should be conducted only by authorized personnel.
Do not connect more than three wires to the terminal block. Always use round
type crimped terminal lugs with insulated grip on the ends of the wires.

cable should be H05RN-F 3G 2.0mm2+H05RN-F 1x0.75mm2
The wiring method should be in line with the local wiring standard.
The breaker of the air conditioner should be all-pole switch; and the distance
between its two contacts should be no less 3 mm.
If the supply cord is damaged, it must be replaced by the manufacturer or its
service agent or a similar qualified person.
If the fuse on PC board is broken please change it with the type of T3.15A/250VAC.
Select wire sizes and circuit protection from table below. (This table shows 20 m

(1) Before starting test run (for all Heat pu p odels)
Confirm whether the power source breaker (main switch) of the unit has been
turned on for over 12 hrs to energize the crankcase heater in advance of operation.
(2) Test run
Run the unit continuously for about 30 minutes, and check the following.
Suction pressure at check joint of service valve for gas pipe.
Discharge pressure at check joint on the compressor discharge pipe.
Temperature difference between return air and supply air for indoor unit.
The following consults are according to the EMC testing.
Through poor conditions of the electrical MAINS, shortly voltage drops can appear
when starting the EQ IPMENT. This can influence other equipment (eg. Blinking
