Transport and storage
Special feature of CETHEO
The CETHEO contains a thermodynamic system equipped with a rotary compressor. This technology
requires essential rules to be followed during transport and handling of the product.
To ensure that the product functions correctly and is reliable after transporting, CETHEO packaging is
equipped with a tilt indicator.
The manufacturer's warranty shall not apply if the tilt indicator result is positive (transport and
handling rules not followed).
Transport, storage and maintenance rules
It is preferable to transport or handle the CETHEO in a vertical position. It may, however, be laid
horizontally (90º max.) from time to time during handling, while respecting the sense as indicated
below. A period of 24 hours must elapse before the CETHEO is started up:
OK NOK
The CETHEO is equipped with a system for displaying whether the product
has been laid in a non-authorised sense. The warranty may under no
circumstances be applied if the product proves to have been transported in
inappropriate conditions.
The CETHEO must be stored in a place sheltered from the weather, dry and at temperatures
between -20ºC and +50ºC. It is strictly forbidden to stack the CETHEO.
In view of its weight, the CETHEO must be handled by two people.

Before starting any work, switch your appliance off.
Under normal functioning, never stop the ventilation system.
When the appliance is not used for a long period, it is essential to drain the tank.

1- GENERAL INFORMATION
VMC + Termodynamic water heater
1.1 - Introduction
This manual is intended for the use of the CETHEO and its peripherals (network, vents, etc.).
It is designed to provide maximum clarity and safety for the design, installation and duration of use.
The products are constantly evolving and so Soler & Palau reserves the right to modify this manual
without prior notice.
1.2 –Warranty and liability
Warranty
The CETHEO warranty is 2 years for the components and 5 years for the tank. This warranty comes
into effect from the date of purchase, and includes the free delivery of spare parts.
The warranty does not cover:
Installation and removal costs
Defects that, in the opinion of Soler & Palau, are due to improper installation, handling, neglect or
accident.
Defects that arise as a result from operations or repair performed by a third party without permission
from Soler & Palau.
To return a defective part, the user should contact their installer.
Liability
The CETHEO is designed for systems providing air renewal and domestic hot water production for
individual residences. Soler & Palau is not responsible for damage caused by:
•Improper use,
•Normal wear of components,
•Failure to follow the instructions in this manual concerning safety, use and installation,
•The use of parts not supplied by Soler & Palau.
1.3 - Safety
Normes générales de sécurité
The CETHEO has an electrical thermodynamic system using high pressure refrigerant gas and a
ventilation system equipped with an electric motor that may constitute a hazard during installation and
starting up. For these reasons, the CETHEO must be handled, installed, started up and maintained
by qualified personnel.
Following installation, there should be no risk to safety, health and the environment according to EC
directives. This also applies to other products used in the installation.
The following general guidelines are important:
Follow the safety instructions to avoid damaging the motorised fan, the heat pump, the hot water tank
and the personnel.
The technical characteristics described in this manual may not be changed
None of the CETHEO components can be modified.
The CETHEO must be supplied with single phaseAC 230 V / 50 Hz.
For the installation to comply with EC directives, the CETHEO must be connected to the electricity
grid in accordance with current standards.
The device must be installed so that under normal operating conditions, there is no risk of contact
with moving parts and power.
The CETHEO meets the legal requirements for electrical equipment.
Before working on the machine, always turn the power off. Use appropriate tools.
Use the appliance only for the purpose for which it is intended.

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%.

Evacuation
Exhaust air from the house:
This spigot is to connect the exhaust air duct from the house.
To avoid heat loss and to best optimise the performance of your system, ducts
should be insulated and pass through the heated area.
Evacuation:
This spigot is to connect the exhaust duct for the exhaust air from inside the house
towards the outside.

This duct must be sealed and insulated to prevent condensation on the
outside and inside.

The CETHEO must be placed in the heated area of the individual residence meeting
The NFC 15-100 criteria.
3 - INSTALLATION
The CETHEO can be transported or moved about on its pallet using a pallet truck.
The CETHEO must
•be placed on a flat floor (to avoid any problems in evacuating the condensates).
•be placed on an area of at least depth 750 depth x 650 length able to support a load of at least 380
kg.
•be in a room with a ceiling height greater than 2.2 m.
•be placed so that access to the front panel is unobstructed (to allow work on the active parts of the
CETHEO).
•be placed as close as possible to the take-off points (to minimise losses).
•be placed as far as possible from the sleeping quarters and in a room with sound insulation on the
walls.
•be placed in a frost-free room.

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 CETHEO must be placed in the heated area of the individual residence meeting
the NFC 15-100 criteria.
For better protection of the tank of your CETHEO, fit an expansion vessel.
