Installation; Air Ducts - CTC EcoWater 300 Instructions D'installation Et D'entretien

2. Installation

The heat pump is delivered complete and preset from factory (electrical
connection may be adjusted to fit local standards). The heat pump should
be installed as close as possible to the existing hot water conduit to minimize
the energy losses.
The place of installation must be in level. Small irregularities can be adjusted
by the feet. When filled the heat pump weighs approx. 465 kg. The place for
the installation must stand a corresponding load.
NOTE: Complementary rules in the building regulations must be observed.
2.1

Air ducts

The air can be taken from the room where the heat pump is placed, or
from another room, or from outside. In these cases the heat pump can be
equipped with duct connections, both at the air inlet and the air outlet. The
air pipe must be insulated to avoid condensation. The air inlet (2) and the air
outlet (1) are located at the top of the heat pump. No connections for the air
are needed if air from the room where the heat pump is placed will be used.
The duct connections are intended for ø160 mm ducts.
If ducts are used pressure losses has to be considered. Fan speed has
to be set on high speed (for fan settings see chapter 4 - control system).
If ø160 mm ducts are used the maximum length is approximately 3 meter
(2 x 90°-bends included). If longer ducts are needed a ø200 mm duct
can be used to reach distances up to 7 meters (2 x 90°-bends included).
If more bends are needed the maximum distance has to be reduced by
approximately 500 mm per 90°-bend.
