Installation procedure
Install indoor unit
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 hole for checking and maintenance.
8.The attentive matters in installation of air suction and discharging duct
9.The examples of improper installation
Do not use air in duct and take the
ceiling inner side instead. The res-
ult 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
*
, wet bulb temperature 24
*
), 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.
