1. SECTION
USE AND FUNCTION
TK Series Climatic Cabinets are developed to simulate real environmental condition by
controlling temperature, humidity and lighting cycles. TK Series Climatic Cabinets are used
for different sectors such as electric and electronic industry, automobile industry, automobile
supply industry, chemical industry, plastic industry, textile industry, pharmaceutical industry,
food industry, packaging industry, plant growth, seed germination, incubation and rearing of
insects.
TK Series Climatic Cabinets maintain temperatures from -10°C to 60°C when the lights are
off and from 0°C to 60°C when the lights are on, humidity from 20% to 95% for temperature
range between 10°C and 60°C. It keeps the temperature and humidity stable within the given
tolerances.
The homogeneity of the temperature and humidity is obtained by the help of the circulation
fan that is located at the upper part of the chamber.
The chamber is made of stainless steel. Fluorescent lamps, starters and other electrical parts
are kept outside of the chamber for easy cleaning of the chamber. The outer body including
the door is made of epoxy-polyester powder coated stainless steel to resist high humidity
levels.
Heating is carried out by using heaters that are located at the upper back side of the chamber,
cooling is carried out by the help of the evaporator which refrigerant gas passes through and
the humidifying is carried out by a humidity generator.
The chamber of TK Series Climatic Cabinets is illuminated from one side by the lamps placed
inside the door. Lighting can be programmed depending on the requirement separately and
two different illumination periods can be programmed. When all the lights are on the light
intensity is about 6000 lux ±%10 for TK 120, 12000 lux ±%10 for TK 252 and 13000 lux
±%10 for TK 600.
Temperature and humidity can be observed on the LC display located on the door.
The humidity is measured by the humidity sensor. The temperature is measured by PT-100
sensor. As the advantage of the system, the recovery time is fast and humidity measurement
sensitivity is %1 Rh and temperature sensitivity is 0.1ºC. The heating is controlled by PID
while cooling is controlled by proportional system.
The control system also contains a comprehensive self-diagnostic system to provide the
information regarding any system malfunction. The self-diagnostic system warns the user in
case of overheating, heater failure, cooling system failure, low water level, full reserve tank.
TK Series Climatic Cabinets are manufactured according to
EN 61010-1, EN 61000-4-2, EN 50419 and EN 55014-1 standards.
This device is in compliance with WEEE Regulation.

INSTALLATION PROCEDURE
3.1. Lifting and Transport
All lifting and transport must be carried out by using proper handling equipment. The
equipment must be supported from underneath and never be turned over.
3.2. Unpacking
Remove the packing box and the second nylon packing around the instrument. The below
written items are provided with the equipment, please check them;
User’s Manual
2 shelves (standard)
4 shelf carriers

Warranty Certificate
Funnel
60 cm. waste water hose
3.3. Positioning
Check that,
No damage has occurred during transport.
The proposed site is suitable for users.
The operator can follow up the test cabinet easily.

The test cabinet does not occupy the utilization space of other instruments or does not

The program and illumination can be performed separately.
WARNING: If the illumination is at “START” position, date and time can not be changed.
4. 5. Completion of the Operation
See that the program is over.

If the printer was used during the run and if there is no need to print stand-by values stop
printing. (see 4.4.4)

Take the samples out. Be careful while handling the samples after the operation as they
can be very hot or cold.

Wipe the chamber surface if needed while the chamber is at room temperature.
You may leave the equipment at the stand-by position or switch it off.
WARNING: DO NOT OPEN THE DOOR WHEN THE TEMPERATURE AND
HUMIDITY LEVELS ARE HIGH INSIDE THE CHAMBER. THIS MAY CAUSE
BURNS ON HANDS AND FACE.

5. SECTION
PERIODIC MAINTENANCE
Protect the chamber against rust coming from outside.
5.1. Every Month
Cleaning
Clean the chamber while it is at room temperature, after unplugging the equipment.

After removing the shelves, wipe down the chamber surface to remove any undesirable
effects of the operations.

Mild detergent use is recommended to remove difficult dust and dirt.

Please be aware of the undesirable effects of the chemicals and be careful while applying
them.
WARNING: DO NOT SPRAY WATER OR OTHER LIQUIDS DIRECTLY ON ANY
PART OF EQUIPMENT. OTHERWISE THIS MAY CAUSE SERIOUSLY
ELECTRICAL DAMAGE.
5.2. Every Three Months
The cooling performance decreases if the condenser is dusty. Clean the condenser by vacuum
machine quarterly. (The period depends on the operating hours of the equipment and the dust
level of the working place.)
Note: In order to clean the condenser; open the right and left cover sheet with the key.
WARNING: SPRAYING WATER OR OTHER LIQUIDS DIRECTLY MAY CAUSE
SERIOUS DAMAGES.
5.3. Every Year
The electrical and mechanical components are extremely reliable and do not need periodic
maintenance. It is advisable to be checked the temperature and humidity calibrations, the
cooling system performance, alarm system’s reliability by authorized technicians once a year.
6. SECTION
DISPOSAL MANAGEMENT CONCEPT
The currently valid local regulations governing disposal must be observed. It is in the
responsibility of the user to arrange proper disposal of the individual components. Applicable
local regulations for disposal have to be carefully observed.
The instruments and electronic accessories (without batteries, power packs etc.) must be
disposed off according to the regulations for the disposal of electronic components.
Batteries, power packs and similar power source have to be dismounted from
electric/electronic parts and disposed off in accordance with applicable local regulations.

7. SECTION
TROUBLESHOOTING
If the instrument fails to operate, check the followings:
The plug is plugged-in properly,
The on / off switch is on,
The plug is not defective,
The mains supply is present.
Fuses are sound,
The installation of the plug is not defective,
If the instrument does not heat, check the followings:
The program is started,
The safety thermostat is adjusted to a temperature higher than set temperature.
Temperature value is set correctly.
The chamber is not overloaded.
The door is closed properly.
The ambient temperature is suitable.
If the instrument does not reach the set humidity level, check the followings:
The set value is set correctly.

The chamber is not overloaded.
The door is closed properly.
Errors Recognised By The Control System
