Upon connected canvas, airflow rate and capacity in
heat pump system will decrease.
•
To fluently drain condensate water from evaporator,
please install the main Unit at a horizontal floor.
If the equipment is tilted, make sure the inclination is
on side of drain vent.
The inclination angle as regards the ground must be
no more than 2°.
•
Install filter inside the Unit.
In case main Unit is connected with canvas, install
filter at the air inlet of duct and then install the duct
(Fig. 5-9 and Fig. 5-10).
•
In case main Unit is connected with canvas, the
diameter of the duct must be ≥190mm, total length of
the ducts must not be longer than 10m or the maximum
static pressure must not exceed 50Pa.
Warning! The duct must have no more than 5 bends.
•
In case main Unit is connected with canvas, when
Unit is operating, condensate dew may form at the
outside of air outlet canvas. Please pay attention
to the discharge of condensate water. We suggest
you to wrap the thermal insulated layer at the outside
of air outlet canvas.
•
Warning! If case of rain entering internal components
of main Unit, the components might be damaged or
injuries might be caused to persons (Fig. 5-7).
•
It is recommended to provide a weather shed in case
ducts are exposed to rain or snow (Fig. 5-8).
