8. The attentive matters in installation of air suction and discharging duct
Recommend to use anti-frost and sound-absorbing duct. (locally bought)
The duct installation work should be finished before the fitment of ceiling.
The duct must be heat insulated.
The specific air-discharging outlet should be installed at the place where the airflow can be reasonably distributed.
The surface should leave a checking meatus for checking and maintenance.

9. The examples of improper installation
Do not use air in duct and take the ceiling inner side instead. The result is because of the irregular outer air mass,
strong wind and sunshine, the humidity is increased.
There may be water drop on the outside of duct. For cement and other new constructions, even if not taking ceiling
inner side as duct, the humidity will also be so high. At this time, use glass fiber to perform heat preservation to the
whole. (use iron net to bind the glass fiber)
Maybe exceeding the unit operation limit (for example: when indoor dry bulb temperature is 35 C, wet bulb temperature
24 C), it may lead to overload of compressor.
Affected by the capacity of air discharging fan, the strong wind in the outer duct and wind direction,when unit air sending
volume exceeds the limit, the discharged water of heat exchanger will overflow, leading to water leakage.
