Chapter4 Common Trouble shooting 4.1 Notices 4.1.1 Working location should be far away from liquid like water. The following environmental conditions are within system tolerances for operation: Temperature:

10º C ~ 40º C

Relative Humidity:

30%~75%, non-condensing

Atmosphere Pressure: 700hPa ~ 1060hPa

4.1.2 It is necessary to put the machine on a flat place during operating. As a result of the poor placement, it may cause bad heat dissipation, appearance wear etc.

4.1.3 Keep the room clean and tidy, because the dust will accumulate rapidly on the air filter and cause the system to overheat. Recommend that the customer to ensure that the dust in the environment is at a low level. Clean the fan filter regularly, if necessary.
