6. AIR CONNECTION
Ecoheat unit has two air connections located at the top cover ofthe system.
There are different installations possibilities:
Since the temperature of the exhaust air is lower t han the in take air flow, the user can recover
this cold air to refresh a room. In this ca se, it is recommended to install a double duct, one to
the room and other to outdoors. Using a gate, the user can stop the air flow conducting it to
outdoors when cooling isn’t needed.
IMPORTANT:
- Do not use flexible duct! Only smooth PVC pipe is allowed.
- Do not use anti -insect grid.
When the inlet and outlet ducting is needed, use only rigid smooth PVC tube.
The pressure drop in the whole air circuit (pipes and accessories) must be lower than the
static pressure of the system, 70 Pa.
In the following table is shown the allowed total pipe length (intake + exhaust). The
equivalent length of any accessory installed in the circuit must be subtract to the maximum
allowed pipe length:
Maximum length (PVC rigid pipe) 1 60 mm 1 7 m
Elbow 90º PVC 1 60 mm 3 equivalent meters
External grid 2 equivalent meters
SUCTION FILTER
The system includes in the air intake a filter for the protection of all the elements of the
refrigera tion circuit. This filter should be checked every 6 months to verify that is has not been
clogged. To do this, remove the filter from the suction duck and check if the channels allow
air passage. Otherwise , wash it with water or replace with a new one.
If you notice that the system does no heat up, check the condition of the filter. A clogged
filter affects the life-cycle performance and hot water production of the system.
