2 –TECHNICAL INFORMATION
2.1 –General definition
CETHEO provides ventilation and hot water for the house. It extracts the air from utility rooms
(Kitchen, Bathroom, Washroom and WC). This hot air at constant temperature throughout the year
(>20ºC) passes through the heat pump (HP) before being ejected to the exterior.
On passing through the HP, the air gives up its energy, resulting in a high and stable coefficient of
performance (COP). This is achieved whatever the outside conditions.

2.3 -Special feature of the CETHEO:
The CETHEO is equipped with a bypass system providing two functioning modes. Ventilation alone
(Figure 2) or Ventilation + HP (Figure 3). In ventilation alone mode, the extracted air bypasses the
filter and the heat pump system. With this system, the power consumed by the fan is reduced and the
lifetime of the filter is extended by about 60%.

4 –HYDRAULIC CONNECTIONS:
•To avoid damage to your installation, check at each step that no metal or other particles have got
inside the tank.
•Check that the cold water pressure is less than 5 bars. Otherwise, fit a pressure reducer.
•The recommended cold water pressure is 3 to 4 bars.
•Remove the front panel by loosening the two screws (1*) at the upper part of the CETHEO.
•Hot and cold water inlets and outlets can be placed at the rear or on the left or right sides.
•Hot water connection:
•To isolate stray currents and avoid the phenomenon of electrolysis,
it is essential to screw on the dielectric connector (2) supplied. The warranty will not
apply to corrosion of the screw threads on the take-off points if this component is not fitted.
•Cold water connection:
•The connection can be made using a new safety unit, NF, set to 7 bars (not supplied).
•There must be no isolation valve between the safety unit and the tank.
•Place an isolation valve upstream of the safety unit.
•It is forbidden to fit a flexible between the safety unit and the tank.
•Provide an outlet connection (F32) for waste water, connected to the safety unit by a
screw-on siphon (water seal 50 mm).
•Condensate connection:
•Passing through the HP evaporator, the air extracted from the house
cools, resulting in condensation that has to be led away.
•Use a transparent flexible tube of the "Tubclair" type with internal diameter
12 mm (allows water flow to be visually checked).
•The tube is connected directly to the take-off point provided (F12 mm external
diameter) out from the condensate tray.
•Make a siphon loop with the flexible tube as shown in figure 7.
•Pass the flexible tube through one of the two orifices used for transport (F32 mm internal diameter) to
the rear part of the CETHEO.
•Connect the other end to the waste water circuit.

•The ducts must be insulated and perfectly inserted. Otherwise, at each thermal bridge there can be
condensation inside the pipe in the extraction part (between the vents and the CETHEO) and in the
exterior part in the discharge part (between the CETHEO and the chimney cap or the façade grille).
•For the extraction circuit, it is preferable to use 50 mm or 25 mm insulated ducting placed under the
insulation.
•When using insulated flexible duct, it is essential to correctly tense it and to give elbows a large
radius. Otherwise, the ventilation flow rates may not be sufficient and will affect first of all the HP
functioning and the air quality in the house, and subsequently the appliance frame (with mould).
