WARNINGS & SAFETY INFORMATION
This unit has to be used under proper conditions according to its technical specification 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 significantly different.(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 fire, power leakage and electrical
shock.)
Do not use this product outside the range of its rated voltage and control capacity.
Install this product in an environment where the temperature ranges from -10 °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 fire.)
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, fire 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
qualified to conduct disassembly and repairs.
(Failure to heed this warning may result in fire, 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 manual, is out of guarantee.

+30.211.70.55.500 +30.210.22.23.283

Make sure that the unit receives power and electrical grounding is made!
Make sure that the electricity cables are drawn from in the correct cross section!
(Please check whether there is heating on cables or not.)
Please check whether the cables in unit control panel are shielded (shielded
magnetic field) or not; make sure shielding is grounded. If not, please change them!
Make sure that fresh air and exhaust air filters are clean and they do not block
the flow of air!
Make sure there is the connection of drainage on the unit, check any possible
clogging in drainage line and clean if necessary!
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.
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.
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.
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.

√
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.
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.

MAINTENANCE
Clean using hot water or steam.
Vacuum Cleaner
Heat Exchanger
Filter
Step 1: Remove the exchanger's service cover,
then remove the heat exchanger out
from the main unit.
Note: The maximum weight of heat exchanger
is 22 kg.
Step 1: Open the maintenance cover. Draw out
the air filters from the unit.
Heat Exchanger Cleaning Air Filter Cleaning
TURN OFF all the power switches before the maintenance is performed.
Do not operate the system without the air filter to protect the components of the unit against being clogged.
Clean up the air filter more than once in a year.
Clean up the heat exchanger more than once per year.
Step 2: Heat exchanger can be cleaned by hot
water or steam. Leave to dry after cleaning heat
exchanger. Connect the unit after making sure
that the heat exchanger has dried.
Step 2: Use a vacuum cleaner to suck up the dust
from the air filter. If necessary, use warm water
with addition a house detergent to remove the
persistent dirt. Leave to dry after cleaning the air
filter. Connect the unit after making sure that the
filter has dried.
