First step: 0.3MPa (3.0kg/cm2g) pressurize 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.
Check if the pressure drops
If the pressure does not drop, the unit is passed
If the pressure drops, please check the leaking point.
After pressurizing for 24 hours, each 1 C difference of ambient temperature
will result in 0.01MPa(0.1kg/cm2g) pressure change. It shall be corrected during test.
Checking the leaking point
From the first to third steps, if the pressure drops, check the leakage in each joint
by the sense of hearing, feeling or soap water, etc. to find the leaking point.
After confirming the leaking point, welding it again or tighten the nut tightly again.
Piping and indoor unit vacuumizing
Use 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

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.
Charging amount of refrigerant
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 the unit with liquid pipe 6.35mm, M=30
For the unit with liquid pipe 9.52mm, M=65
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.

compressor in original state
In heating mode, there is auto temp. compensation, the requested condition: the time is less than 5
minutes between the moment compressor stops when arriving the set temperature to the moment
when compressor starts up again. The principle is as follow:
A. △T=Ts-Tr(room temp. when compressor starts up)
B. When Ts-Tr≥2℃, △T=2℃; when Ts-Tr=1℃, △T=1℃; when Ts-Tr≤0℃, △T=0℃.
C. When temp. compensation works, if pressing remote controller temp. decreasing button, △T=0℃;
if pressing temp. increasing button, △T remains original value.
Anti-current rush protection: After compressor runs for 1.6 seconds, outdoor motor, indoor motor can
work.
Outdoor motor and the compressor runs or stops simultaneously (except for overheat protection),
indoor fan speed can be set at High, Med, Low or Auto speed, and the fan blade can swing or be fixed
on one position. You can set TIMER or SLEEP mode.
3) Overheat protection
In heating mode, when compressor has started up and indoor fan motor has run for over 30 seconds,
if indoor coil temperature Tg>60℃, outdoor motor will stop; if Tg<56℃ and outdoor motor has
stopped for 45 seconds, outdoor motor will resume; if Tg>68℃, compressor will stop, and indoor
motor will run as the condition that thermostat is OFF. After the compressor stops for 9 minutes and
Tg has decreased to
48℃, the system will resume to heating mode, and compressor and outdoor motor will continue to
work.
If Tg>56℃, low speed of indoor motor is invalid, so fan motor will turn into med speed. If Tg>60℃,
med speed is invalid, so fan motor will turn into high speed. If Tg<52℃, fan motor will resume to
original speed. Overheat protection will be controlled by outdoor MCU according to the actual
temperature.
4) Anti-cold air function in heating
After entering heating mode for the first time or defrosting is over, if Tg is below 28℃, indoor motor
will stop; if Tg is over 28℃ and below 38℃, indoor motor will run at low speed; if Tg is over 38℃ or
compressor has run for over 4 minutes, indoor fan motor will run at the set speed.
5) Blowing remaining heat

the max. time is 56 seconds, if it is over 56 seconds, the filter will stop going down.
B.
If receiving go-up command after stopping for 1 second, the filter will go up immediately, and
the max. time is 58 seconds; if checking that gate switch signal is off during going up, the filter will not
go up and enter adjusting, that is: going down for 1 second, stop 1 second, going up for 2 seconds,
stop 1 second, repeat like this for 3 times, then the filter operation is over.
C.
If receiving go-up command during going down, going down will stop; if receiving going up
command again and stop time is up to 1 second, the filter will go up and the up time is 2 seconds
more than the down time. After going up is over, the filter enters adjustment and then stop.
D.
If receiving go-down command during going up, going up will stop; if receiving going down
command again and stop time is up to 1 second, the filter will go down and the down time is 2
seconds less than the up time.
E.
If receiving go-up or go-down command after the up/down operation stops, the filter can
continue going up or down, but the total up or down time can not be more than (56+2) seconds and
56 seconds.
11.14 Pressure switch control
For the unit without outdoor PCB, if pressure switch is not selected, the relative function is not
available; For the unit without outdoor PCB selects pressure siwth, the procedure is as follow: after
compressor runs for 3 minutes, the unit will check pressure switch, if pressure switch is overlow and
low pressure switch action works for over 30 seconds, compressor and outdoor motor stops,
meanwhile, alarm will occur, and compressor will not start up; If being electrified again after power off,
the protection can be cancelled.
11.15 3-minute protection of compressor when startup
Once the compressor stops running, you can restart up only after 3 minutes. When the unit powered
off in operation, if the shutoff time is below 3 minutes, it will be 3 minutes at least after powered on
when the compressor starts up again. Powered on for the first time, there is no 3-minutes delay
protection.
