●Cabling
Check that cabling will not be subject to wear, corrosion,
excessive pressure, vibration, sharp edges or any other adverse
environmental effects. The check shall also take into account
the effects of aging or continual vibration from sources such as
compressors or fans.
●Detection of flammable refrigerants

Under no circumstances shall potential sources of ignition be used
in the searching for or detection of refrigerant leaks. A halide torch
(or any other detector using a naked flame) shall not be used.
●Leak detection methods

The following leak detection methods are deemed acceptable for
all refrigerant systems.
Electronic leak detectors may be used to detect refrigerant leaks
but, in the case of flammable refrigerants, the sensitivity may not
be adequate, or may need re-calibration.
(Detection equipment shall be calibrated in a refrigerant-free area.)
Ensure that the detector is not a potential source of ignition and is
suitable for the refrigerant used.
Leak detection equipment shall be set at a percentage of the
LFL of the refrigerant and shall be calibrated to the refrigerant
employed, and the appropriate percentage of gas (25 % maximum)
is confirmed.
Leak detection fluids are suitable for use with most refrigerants
but the use of detergents containing chlorine shall be avoided as
the chlorine may react with the refrigerant and corrode the copper
pipe-work.
If a leak is suspected, all naked flames shall be removed/
extinguished.
If a leakage of refrigerant is found which requires brazing, all of
the refrigerant shall be recovered from the system, or isolated (by
means of shut off valves) in a part of the system remote from the
leak. For appliances containing flammable refrigerants, oxygen
free nitrogen (OFN) shall then be purged through the system both
before and during the brazing process.

Analysis or processing of some of the malfunction display:

1. Compressor discharge protection
Possible causes: shortage of refrigerant; blockage of air filter; poor ventilation or air flow short pass for condenser; the sys-
tem has noncondensing gas (such as air, water etc.); blockage of capillary assy (including filter); leakage inside four-way
valve causes incorrect operation; malfunction of compressor; malfunction of protection relay; malfunction of discharge sen-
sor; outdoor temperature too high.
Processing method: refer to the malfunction analysis in the above section.
2. Low voltage overcurrent protection
Possible cause: Sudden drop of supply voltage.
3.Communication malfunction
Processing method: Check if communication signal cable is connected reliably.
4. Sensor open or short circuit
Processing method: Check whether sensor is normal, connected with the corre sponding position on the controller and if
damage of lead wire is found.
5. Compressor over load protection
Possible causes: insufficient or too much refrigrant; blockage of capillary and increase of suction temp.; improper running of
compressor, burning in or stuck of bearing, damage of discharge valve; malfunction of protector.
Processing method: adjust refrigerant amount; replace the capillary; replace the compressor; use universal meter to check if
the contactor of compress or is fine when it is not overheated, if not replace the protector.
6. System malfunction
i.e.overload protection.When tube temperature(Check the temperature of outdoor heat exchanger when cooling and check
the temperatur e of indoor heat exchanger when heating) is too high, protection will be activated.
Possible causes: Outdoor temperature is too high when cooling; insufficient outdoor air circulation; refrigerant flow malfunc-
tion.
please refer to the malfunction analysis in the previous section for handling method .
7. IPM module protection
Processing method:Once the module malfunction happens,if it persists for a long time and can not be selfcanceled, cut off
the power and turn off the unit,and then re-energize the unit again after about 10 min.After repeating the procedure for sever
times, if the malfunction still exists,replace the module.

If malfunction occurs,corresponding code will display and the unit will resume normal until protection or
malfunction disappears.

2.Min. length of connection pipe is 3m.
3.Max. length of connection pipe and max. high difference.(More details please refer to the specifications.)
4.The additional refrigerant oil and refrigerant charging required after prolonging connection pipe
● After the length of connection pipe is prolonged for 10m at the basis of standard length, you should add 5ml of refrigerant oil for each
additional 5m of connection pipe.
● The calculation method of additional refrigerant charging amount (on the basis of liquid pipe):
● Basing on the length of standard pipe, add refrigerant according to the requirement as shown in the table. The additional refrigerant
charging amount per meter is different according to the diameter of liquid pipe. See the following sheet.
● Additional refrigerant charging amount = prolonged length of liquid pipe X additional refrigerant charging amount per meter
