Malfunctioning of the unit and error codes

When an error occurs or the protection mode is set automatically, the circuit board and the wired controller will both display
the error message.

When remote signal is on, no P7 will be showed on the controller, when remote signal is off, P7 will be displayed. It is
not an error code, but a situation for remote on/off signal.
WARNING!
and seek technical assistance specifying the device model purchased.

13. DISPOSAL.

At the end of their device lifecycle, the appliance must be disposed in conformity with the applicable regulations.
WARNING!
nance and disposal operations must only be carried out by qualified personnel. This device contains R513a refrig-
erant in the amount as stated in the specification. Do not vent R513a into the atmosphere: R513a, is a fluorinated
greenhouse gas with a Global Warming Potential (GWP) = 631.

Corrective actions
1) Check the sensor connection
2) Replace the sensor
1) Check the sensor connection
2) Replace the sensor
1) Check the sensor connection
2) Replace the sensor
1) Check the sensor connection
2) Replace the sensor
1) Check the sensor connection
2) Replace the sensor
1) Check if the air inlet temp is over
the working limited
2) Check if the tank is full of water. If
not, charge water
3) Replace the electronic expansion
valve assembly
4) Discharge some refrigerant
5) Replace a new switch
6) Discharge and then recharge the
refrigerant
