4.2 Product
The basic principle is to transfer the return water load in the system to air by the aid of a heat
exchanger including fans. Its working principle is that the air sucked by fans cools the fluid
within the tube while it passing through the fins. Thanks to closed fluid circuit, quantity of
water does not diminish hence it is not needed to add extra water to the system.
The unit is delivered for operation with a specific operating point:
• Air inlet temperature and volumetric flow
• Fluid inlet temperature and volumetric flow

4.5 Sound pressure level
Noise pressure levels (LpA) are determined from the sound power levels (LwA) by using
following formula according to EN 13487 Surrounding Surface Method.
Sp = parallel piped surface at 10 m
Sr = surface reference(1m2)
Sound pressure levels given show the average values on a parallelpiped surface at 10 m
distance from the unit in open air over a reflecting plain.

7. OPERATION
7.1 Initial commissioning
Before running the unit for the first time, be sure that all guards, motor mountings and
electrical covers are secure, installation and electrical connection are done properly, internal
wiring is kept away from the fans and the fans can rotate freely.
Make sure that all the mechanical connections are done in accordance with the rules. Piping is
consistent with the guidelines. Before the start-up you may run the fans individually to make
sure that they are running properly. Turn on the fluid valves and let the fluid flow right before
running the fans. In case you may encounter any problem or disfunction please refer to the
manufacturer for the resolution of the problem.
7.2 Regular commissioning
If the product is stationary for long periods in a humid atmosphere, the fans must be switched
ON for minimum of four hours in every month to remove any moisture that may have
condensed within the motors.
While the fans are running, anything that could pass through the finger guards, like a piece of
cloth or long hair, must be kept away from the fans.
• Switch on the main power switch
• Make sure that the fluid is flowing inside the pipes.

the product down.
After shutting the unit down the operating pressure must be observed whether the
operating pressure exceeds maximum operating pressure or not.
Stay away from the air direction of the fans while the fans are running.
Before touching, it is recommended to ensure that the headers and the connection pipes
are neither too hot nor too cold due to working conditions of the fluid inside.
The operation must be stopped and the supplier must be informed in case of any unusual
working condition, such as abnormal operating noise. Intensive vibrations due to out-of-
balance running of the fans may lead to outage.
Maintenance must not be performed while the product is in use (See part 8 for details).
As it is not possible to evacuate fluid fully, antifreeze must be added to product for safety.
(See part 8 for details)
Recommended starting value for fans is 6 per hour while maximum is 10.
7.4 Step control application (If Applicable)
In step controlled applications; the fan groups that will be working and not working must be
arranged according to scheme given below which is defined as “TRUE”. Otherwise the
problems given below will be observed:
1. The air will not be fully absorbed from by the fans. Hence the efficiency will decrease.

2. When a fan is taken into the circuit which rotates in contrary directions, the fan will be
damaged because of constriction.
8. MAINTENANCE
8.1 Maintenance intervals
Maintenance operation is to be performed by qualified personnel only. Please be sure that
safety regulations and the worker's protection rules are obeyed during the maintenance and
service (DIN EN 50110).
The fluid circulation must be stopped and it must be ensured that no electrical supply
connection exists during maintenance. It is advisable to wait till the product comes to thermal
balance with its surroundings if possible.
Freezing Protection; Since it is not possible to drain all of liquid from the system, dry
coolers have freezing threaten. Therefore fluid must be protected against freezing by
adding adequately amount of antifreeze to the fluid. On the other hand, quantity of
added antifreeze must be checked whether it decreases or not.

If the tubes within the product or the connection pipes are to be repaired, the fluid in the line
must be drained beforehand.
8.2 Fan motor maintenance
• Regarding the bearings, the fans are maintenance-free for 30000-40000 hours under
normal operating conditions. Lifetime lubrication is not necessary within this period,
and when this period expires or the bearings are damaged, it is necessary to replace the
bearings with original parts.
• If the fans are to be maintained, the instruction manual prepared by the fan
manufacturer must be followed. Please contact manufacturer when needed.
• After maintenance is performed, ensure that no tools or other foreign materials are left
in or near the product.

Follow to Initial Commissioning before operating the product after maintenance.
8.3 Periodical controls (Once a year)
• Corrosion on the fins and tubes should be inspected. If the tubes are worn-out, leakage
may occur.
• The pipeline must be controlled for damage and leakage.
• Mechanical and electrical connections of the fans must be checked. Fans must be able
to rotate freely and finger guard must be stable.
• All the fixings, especially fan motor mountings and product installation fixings must
be ensured to be secure.
8.4 Clean up
Cleaning the fins
• One of the effective method to clean up the fins is to spray pressurized air. This
action should be conducted after stoppig the fans and turning off the fluid supply
valves. The air jet should be provided to be parallel to the fins for the best cleaning
results.
• Fins could also be cleaned up by pressurized water jet. The water jet should be
provided to be pararllel to the fins for best result. . This action should be conducted
after stoppig the fans and turning off the fluid supply valves. The cleaning action
should be carried out inside-out. Some harmless solvent/detergents could be added
to the water to ease the removal of hardened dirt. Any known corrosive/abressive
chemichal should be avoided to be used in cleaning action.
• The wiring and fans should not be wetted during the cleaning process.
Celaning up the Fans
• Fans should be cleaned with the aid of pressurized air and a soft brush.
