• This unit has to be used under proper conditions according to its technical
specication and design purpose. (Otherwise responsibility belongs to
practitioner)
• Unauthorized personnel must not interfere in unit and/or must not use
unoriginal spare parts. (Otherwise responsibility of failure that may occur
belongs to practitioner)
• Do not install this product in a refrigerated warehouse, heated swimming pool
or other location where temperature and humidity are signicantly di󰀨erent.
(Failure to heed this warning may result in electrical shock or malfunctioning.)
• Do not install this product where it will be directly exposed to rain.(Failure to
heed this warning may result in electrical shock or malfunctioning.)
• Do not install this product in a location where acid, alkali or organic solvent
vapors, paints or other toxic gases, gases containing corrosive components
or high concentrations of oily smoke are present (Failure to heed this warning
may result not only in malfunctioning but also re, power leakage and electrical
shock.)
• Do not use this product outside the range of its rated voltage and control
capacity.
ATTENTION
• Install this product in an environment where the temperature ranges from
0 °C to +40 °C and the relative humidity is less than 60%. If condensation
is expected to form, heat up the fresh outside air by a duct heater etc.
• Select an adequately sturdy position for installing the product and install it
properly and securely.
• Use the designated electrical wires for the terminal board connections and
connect the wires securely so that they will not be disconnected.(Failure
to ensure proper connections may result in re.)
• When passing metal ducts through wooden buildings clad with metal
laths, wire laths or metal, these ducts must be installed in such a way that
they will not make electrical contact with metal laths, wire laths or metal
sheets.(Power leakage can cause ignition.)
• The outside ducts must be tilted at a gradient (1/30 or more) downwards
toward the outdoor area from the main unit, and properly insulated. (The
entry of rain water may cause power leaks, re or damage to household
property.)
• Gloves should be worn while installation. (Failure to heed this warning
may result in injury.)
• A dedicated circuit breaker must be installed at the origin of mains power
supply. This circuit breaker must be provided with a means for locking
(lock and key).
• The body of the unit, room control panel and cables keep away the unit
3 m. distance

• This product must not be disassembled under any circumstances. Only
authorized repair technicans are qualied to conduct disassembly and
repairs. (Failure to heed this warning may result in re, electrical shock or
injury.)
• Connect the product properly to the ground.(Malfunctioning or power
leaks can cause electrical shock.)
• An isolator switch having minimum contact gap of 3 mm in all poles must
be provided as a means of disconnecting the power supply.
NOTE: The installations,which is not available for installation and operation

CHECK LIST
In the event of unit failure and pre-commissioning checks to be made are determined as
follows; after checking this information, please contact our company in case failure continues.
Controls
1. Make sure that the unit receives power and electrical grounding is made!.............................................
2. Make sure that the electricity cables are drawn from in the correct cross section!
(Please check whether there is heating on cables or not.)........................................................................
3. Pleasecheckwhetherthecablesinunitcontrolpanelareshielded(shieldedmagneticeld)
or not; make sure shielding is grounded. If not, please change them! ...................................................
4. Makesurethatfreshairandexhaustairltersarecleanandtheydonotblocktheowofair! ..........
5. Make sure there is the connection of drainage on the unit, check any possible
clogging in drainage line and clean if necessary! .....................................................................................
6. Please check whether the diameter of the air duct connection of the unit and
the diameter of the spigot are the same. If the duct connection is smaller, change
it with the correct one....................................................................................................................................
7. Make sure the electrical connections of the unit are made as suggested on the
unit and in this guide, check if there is incorrect connection. ..................................................................
8. Make sure during the installation of the unit there is enough space for the service
and if there is not enough space, re-install again.......................................................................................
9. In extremely cold climate applications, frost may occur on the exchanger, apply electric
heater in fresh air intake section of the unit to get the temperature to -8 °C and above. ......................
10. After installing the unit, make sure that it does not create an abnormal sound
or vibration, if there is, make sure that rubber pads are used. .................................................................
