2. Clarification of Cool-Spot system controls,
operation and side-effects:
Activating the Cool-Spot system (CS system):
Tap the (on / off symbol) to boot the CS system.
The LED lighting is activated, the system begins to ventilate and you may pick up a faint ozone scent.
After several minutes, the air-cooling system is activated.
Activating the Vapour system:
The screen will now turn orange and display the following notification: Vapour system being filled.
When inactive, the reservoir is dry and continuously disinfected with ozone.
The reservoir is now automatically filled up with clean RO water.
Once the required water level is reached, the vapour system is activated according to the latest setting
for the amount of vapour, e.g. 60% = 3 arrows.
Vapour is now being emitted by the CS console.
If the system has been disconnected from a 230V power source, the vapour amount needs to be
reconfigured using the button.
Cool-Spot in operation:
The current temperature of the air emitted by the console is displayed on the screen.
Once operational, the air temperature will drop from the ambient temperature to a value of around -4, -5°
C .
The temperature control of the CS system ensures that the outgoing air temperature remains between
-5 and -2 degrees Celsius.
A temperature of 3.4 °
C will be displayed on the screen periodically. This indicates that the cooling
system is defrosting until that air temperature has been reached. After a brief moment, the actual air
temperature reappears on the display.
Cool-Spot is Fresh stays Fresh
The Cool-Spot climate for preserving fresh products is now being created by a mix of vapour and cold air.
The area above the buffet or work surface is chilled to a temperature below 7°
C with maximum air humidity.
Apply correct vapour settings to ensure the products are kept at the right temperature and do not become
dry or moist.
Temperature configuration:
The operational temperature of CS is factory-configured to remain between -5 and -2 ° C .
The average operational temperature can be increased according the client’s request.
RGB(W) LED lighting colour configuration:
The default setting of the exhaust console LED lighting is Warm White.
The LED lighting remote control is located inside the system casing upon delivery of the CS system.
It can be used to preconfigure all colour combinations.

3. Side-effects of Cool-Spot usage in various circumstances.
Condensation formation on the stainless steel exhaust console:
The console is properly insulated on the inside.
The air flowing out of the console is cold which cools certain exterior elements as well.
This may cause condensation to form.
Whether or not and to what extent condensation will form, depends on the ambient air humidity and
cannot be prevented.
If the condensation becomes a nuisance during Cool-Spot operation, it can be wiped off with a cloth.
How to remove water drops emerging on the exhaust nozzles:
Getting the chilled climate to maximum humidity requires little vapour.
Exceeding the required vapour amount creates a nice visual effect but also increases the risk of
condensation.
The vapour coming from the black nozzles is 100% ultra-fine, clean, misted water that is emitted
with cold air. This will cause condensation to form on the nozzles due to the temperature
difference with the ambient air. This condensation needs to be wiped with a tissue regularly to
prevent water drops from falling onto the product.
Drops that form on the nozzles are 100% clean and safe!
Reduce exhaust vapour to lower the risk of condensation.
Buffet or work surface temperature and condensation:
Upon activation of the Cool-Spot system, the buffet or work surface has the same temperature
as its surroundings. The vapour-infused cold air from the console reduces the temperature of the
surface and the area above it up to approximately 5 - 6°
C . This does not cause any condensation
on the surface or the products, which is how it is intended. However, some condensation may
form if the vapour is set too high.
When the CS system has been turned off, the buffet or work surface with products is still cold.
Since no cold air is being emitted from the console any longer, the warmer ambient air may
cause condensation to form on the surface and the product.
Some condensation may occur on cold dishes straight from the freezer or clay dishes presented
with crushed ice underneath the CS system. This is due to the fact that the temperature inside
the Cool-Spot zone of approximately. 5°
C exceeds the temperature of the dish placed on the ice.
Barely any condensation will form when using plastic dishes together with ice underneath the
CS system.
No condensation will form on fish, seafood etc. presented directly on ice underneath the
CS system. When using gastronorm dishes that are being chilled from below, underneath the CS
system, place griddle on the bottom of the dishes to keep the products condensation-free.

Vapour exits the CS exhaust console nozzles unevenly:
It is normal for the vapour to exit the nozzles irregularly at times.
It may appear as less vapour is emitted by the first two nozzles next to the main column,
but this is partially an optical illusion caused by the aerodynamics of the vapour jet.
When configuring the vapour system in the factory, the so-called spoilers are positioned inside
the console to ensure the most even exhaust effect as possible.
The spoilers can be readjusted on-site if necessary.
The effect of draught near the Cool-Spot:
The Cool-Spot climate consists of a mix of cold air and vapour and is transferred to the buffet or
work surface as gently as possible. It essentially floats over the buffet to the edge of the surface.
As a result, the effect of the cold energy on the product is optimised with a minimum loss of energy.
The floating cool climate is vulnerable, comparable to smoke that can be dispersed with the
wave of a hand. Strong draughts resulting from open doors in the room or a poorly balanced
exhaust system may disrupt the effect of the chilled climate at times.
A more powerful airflow can mitigate this disruptive effect.
However, this will also cause the majority of the climate to be forced across the surface which
will increase the rate of energy loss and decrease the cooling effect.
What can you do to reduce the effect of draughts?
If you notice that the pattern of vapour outflow is subject to strong fluctuations, is being blown
away or pulled underneath the console upon activating or deactivating the exhaust, it is clear
that the exhaust needs to be adjusted.
Air streams in the room where the Cool-Spot is located cannot be avoided, one way of dramatically
improving the behaviour of the vapour jet is by protecting the CS piece with a room divider, mobile
wall panel, tall piece of furniture or a large plant trough.
Recap:
At Cool-Spot BV, we are aware that condensation drops from the vapour nozzles or the stainless
steel elements may cause some nuisance while the equipment is being used.
Unfortunately, condensation cannot be completely avoided, as explained above.
Regular removal of drops requires your awareness and takes time.
In our experience, Cool-Spot users quickly learn to deal with these minor discomforts and they
are strongly outweighed by the benefits that the Cool-Spot system has to offer.
Feel free to get in touch by telephone or email for any questions or further explanation.
We are here to support you and ensure maximum satisfaction
with our Cool-Spot system.

By following these instructions, you can be certain that unprotected Fresh Produce can be presented
at appropriate HACCP climate conditions for an extended period of time without loss of quality.
A Cool start:
Turn on the system a few minutes before the presentation session.
When the Cool-Spot is switched on, the unit top will still be at the same temperature as the room,
and it will take some time before the “warm” top itself has cooled down.
Depending on the material of the top, pre-cooling will vary between 15 and 30 minutes.
From Cool straight from the refrigerator to Cool under Cool-Spot:
Fresh produce should reach the buffet at the correct temperature, so you should ensure good
preparation and logistics for "smoothly" setting up your buffet.
Cool-Spot isn't intended to "re-cool" the product, and it will take some time for products that are too
warm when presented to reach the right temperature. Incidentally, there are practical solutions for
refrigerated, insulated internal transport for the catering industry.
No two trays are the same! Stone works better than plastic:
In practice, trays or platters made of genuine stone, ceramics, natural slate etc.
retain coolness better than trays made of melamine wood or other insulating material.
Dark coarse stone-like material works better than white shiny plastic that repels cold.
Buffet tops made of marble, granite or hard stone are better than composite:
Composite contains synthetic resin, which has an insulating effect and is slow to absorb cooling
energy. Light-coloured and smoothly polished buffet tops appear to have an insulating effect.
An improperly insulated buffet top will allow heat to penetrate from underneath the unit, which is
highly detrimental to maintaining temperature at the bottom of the trays.
Every little helps:
For composite tops or melamine material, it is beneficial to opt for trays with small mounting feet
rubber plates, so that they are suspended from the unit top. The cold CS climate can then also flow
under the tray, meaning the heat from underneath the the unit will no longer impact on the dish.
1. Limit the height of the trays to below the nozzles for the climate to flow over the product.
Avoid direct sunlight or lighting on the buffet by shielding it or setting it up differently.
Prevent a strong airflow in the Cool-Spot system, and make sure it is shielded.
ake sure that the extractor hood near the buffet is balanced and isn't affecting the CS climate.
Check that produce has been placed under the CS system at the correct temperature.
