Checks after Installation
Items to be checked Possible result in case of improper installation
Is the installation secure? The unit may fall, vibrate or give out noise.
Is the leakage detection done?
Possibly causing low cooling capacity (heating capacity).
Is the unit heat insulated satisfactorily? Possible dew or drips of water.
Is the water drainage smooth? Possible dew or drips of water.
Is the power voltage identical to the ratings on
nameplate?
The unit may be incurred to failure or the parts may be
burnt.
Are the cables and pipes connected correctly? The unit may be incurred to failure or the parts may be
burnt.
Is the unit safely earthed? Risk of electric leakage.
Does the cable type conform to the specication? The unit may be incurred to failure or the parts may be
burnt.
Is there obstacles at the air inlet and outlet of indoor and
outdoor unit?
Possibly causing low cooling capacity (heating capacity).
Are the refrigerant pipe length and refrigerant fill
recorded?
Unable to control the quantity of refrigerant lled.
Note to the installer
• After installation, be sure to explain to the customer enough about the system.
• Transport/storage temperature should be at -25-55°C and for short period not exceeding 24h at
up to +70°C.

Note:
•
The design of this unit conforms to the requirements of EN14511 standard.
•
The air volume is measured at the relevant standard external static pressure.
•
Cooling (heating) capacity stated above is measured under nominal working conditions
corresponding to standard external static pressure. The parameters are subject to change with
the improvement of products, in which case the values on nameplate shall prevail.
