1.1 Check for Wiring
WARNING!
Do not check for the power supply unless proper checkout equipment has prepared and preventive
measures have been taken, otherwise it would lead to severe injury.
Are sizes of connection lines and the air switch proper?
Does wiring comply with relative standards and electric codes?
Is there any incorrect wiring?
Does each contact work properly?
Is the power supply and insulation proper?
Are initial set points of control and protective elements satisfied?
1.2 Check for the Water System
Are water inlet and outlet directions correct?
Is the water piping cleaned? Are there foreign matters at the pipe joints? Is the water quality
satisfied?
Is insulation of water pipes in good condition?
Does exhaust valve of the water system work properly?
1.3 Check for the Communication System
When the unit is powered on, check for the communication system, including: communication
between AP1 and AP2, between the wired controller and the main board. When there is unusual
communication, this error will be displayed at the wired controller. Then, check out the cause according
to the displayed error. See the figure below for wiring of the communication system.
1.4 Trial Run
Start the unit when there is no any problem for wiring and piping. After startup, check for the
electrostatic expansion valve, water pump, fan, and compressor to see if they work normally. When
there is any error, solve it according to the troubleshooting flowchart covered in this manual. However, if
the troubleshooting flowchart is still unhelpful, please contact GREE sales agent.
