Bend piping with as wide angle as possible.
Keep insulating both gas and liquid piping.
Check flare-connected area for gas leakage.
Piping connection
Connecting method (indoor unit)
Apply refrigerant oil at half union as large and flare nut.
To bend a pipe, give the roundness as possible not to crush
the pipe.
When connecting pipe, hold the pipe centre to centre then
screw nut on by hand, refer to Fig.
Be careful not to let foreign matters, such as sands enter
the pipe.
Forced fastening without centering
may damage the threads and cause
a gas leakage.

Air discharging method
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).

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
as the following figure shown.

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 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.

Drain hose
(Maximum local drain up dimension)
common pipe about 100 mm below the drain outlet of each
unit as shown in the sketch. Use VP-30(11/4") or thicker pipe
for this purpose.
(e) Be sure to provide heat insulation to hard PVC pipes of indoor
placement.
(f) Do not ever provide an air vent.
(g) The height of the drain head can be elevated up to a point
500 mm above the ceiling, and when an obstacle exists in the
ceiling space, elevate the piping to avoid the obstacle using
an elbow or corresponding gadget. When doing this, if the
stretch for the needed height is higher than 500 mm, the backflow quantity of drain at the event of interruption of the operation
gets too much and it may cause overflow at the drain pan.
Therefore, make the height of the drain pipe within the distance
given in the sketch below.
(h) Avoid positioning the drain piping outlet at a place where
generation of odor may be stimulated. Do not lead the drain
piping direct into a sewer from where sulfur gas may generate.

Conduct a drainage test after completion of the electrical work.
During the trial, make sure that drain flows properly through the piping and that no water
leaks from connections.
In case of a new building, conduct the test before it is furnished with the ceiling.
Be sure to conduct this test even when the unit is installed in the heating season.
Procedures

Supply about 1000 cc of water to the unit through the air outlet using a feed water pump.
Check the drain while cooling operation.
Pour water into a convex joint.
Insert water supply hose
for 20 mm ~ 30 mm to
supply water.
(Insert hose facing
toward bottom.)
Attached drain hose clamp
Remove grommet.
Make sure to install
it back after test.

(In the electrical work has not been completed,
connect a convex joint in the drain pipe connection
to provide a water inlet. Then, check if water leaks
from the piping system and that drain flows through
the drain pipe normally.)

(4) Cutoff protection against overload and overheat
During heating program, if the indoor blowing fan has been started and the compressor
has been running more than 2 minutes, and the temperature of indoor coil pipe (Ticp)
> 64 , the outdoor blowing fan will stops running; If Ticp ” 50
and the outdoor
blowing fan has kept stop state for 45 seconds, then it will restore rotation; If Ticp > 67
and such temperature has last for 10 seconds, the compressor will stop running and
indoor blowing fan run according to conditions as it reaches setting temperature. When
Ticp < 58 , and the compressor has kept stop state over 3 minutes, then the
compressor and outdoor blowing fan will restore normal running.
Cutoff protection for heating current
After 60 seconds from the compressor being started, if CT current exceeds I1 (9.2A) and
such case has kept 5 seconds, the outdoor blowing fan will stop. If 45 seconds has passed
after the outdoor blowing stops and the current of the compressor is less than I2 (7.5A), the
blowing fan will restore running. If CT current exceeds I3 (14.3A) and such case lasts for 3
seconds, the compressor and outdoor blowing fan will stop. The compressor will not restore
running until 3 minutes passes with CT current less than 12A.
(5) Cool wind prevention during heating program
At the first time entering heating program or after ending the latest frost removal, if the
temperature of indoor coil pipe (Ticp) < 28 , the indoor blowing fan will stop running; If
28
Ticp < 38 , the indoor blowing fan will run at low speed; If Ticp > 38
or the
compressor has been running for more than 4 minutes, the indoor blowing fan will run at

setting wind speed.
(6) Afterheat blowing during heating program
During heating program, the compressor will stop running (except overheat protection or
frost removal) while the indoor blowing fan will firstly run for 50 seconds at low speed then
stop.
(7) Frost removal control (applicable for cooling-heating type)
Starting conditions for frost removal:
A
The indoor unit is in overload protection and outdoor blowing fan stops. The outdoor
blowing fan does not enter overheat mode in 10 minutes after it is restarted, the
compressor has run over 45 minutes totally while 20 minutes continuously, and the
temperature of indoor coil pipe is lower than 43 ;
B
After the compressor continuously running for 20 minutes, the temperature of indoor
coil pipe falls 1 every 6 minutes and such case continuously appears three times,
and the temperature of indoor coil pipe is less than 40 , and 5 minutes have passed
after the compressor is restarted;
C
The compressor has run totally over 3 hours while 20 minutes continuously, and the
temperature of indoor coil pipe is less than 40 ;
D
The difference between room temperature and the one of indoor coil pipe is less than
16
and the compressor has totally run over 45 minutes while 20 minutes
continuously;
Frost removal will start if any one of the above conditions is satisfied.
Ending conditions for frost removal:
1 Time of frost removal has exceeded 9 minutes;
2 CT current exceeds I4(8.2A)
Actions of each load after the frost removal starts:
The compressor and outdoor blowing fan stop, and indoor blowing fan also stops.
55 seconds later the reversal valve is closed and next 5 seconds later the compressor is
started.
Actions of each load after the frost removal ends:
The compressor stops running while outdoor blowing fan immediately runs at high
speed, 55 seconds later the reversal valve is opened and next 5 seconds later the
compressor restores running and indoor blowing fan runs as conditions for cool wind
prevention.
(8) Freeze protection
After the compressor has run for 9 minutes, the system will check temperature of
indoor coil pipe (Ticp). If Ticp is less than -1 , the compressor and outdoor blowing
fan will stop. They will run again after the compressor stops if both the following
conditions are satisfied:
1) 3 minutes have passed since compressor stops.
2) Ticp exceeds 7 .
(9) 3 minutes protection for compressor
After compressor stops, it cannot be started until 3 minutes later. During the machine’s
running, if time after loosing power not exceeds 3 minutes, the compressor cannot be

control panel beeps 2 times.
(11) Control of water pump
a. In cooling (including automatic cooling mode) and dehumidifying modes, the water
pump works if the compressor runs while stops 5 minutes later after the compressor
stops.
b. When water tank is fully filled, the float switch will be off. The water pump will start
to work after a controller has detected this signal and it will continue working for 5
minutes after the float restores to normal state.
c. If the full water signal is detected continuously over 5 minutes, the water pump
indicator lamp will flash to alarm and compressor stops running. The water pump
will run 5 minutes, then pause for 5 seconds before next 5 minutes’ running, ... until
the float restores to normal state, after which the pump will run for 5 minutes then
stop.
(12) Monitoring of remote network
Through preset interface, the air conditioner is connected to remote control detector
(made by Haier) with 2-core cables for wire communication, to execute instructions sent
from computer or centralized controller via remote control detector and meanwhile send
present running status and trouble information of the machine to remote control detector.
