3. Device Description
What is the
A compact device which generates cold air for skin cooling.
What does it
The Cryo 5 produces cold air at that can be applied with variable
air current flows.
What are the
the Cryo 5?
The preset parameters are user friendly. A large cold air
production capacity is provided. Only ambient room air and
electricity are required. No consumables.
How can you reach
the desired cold
Depending upon the surface and the access of the area to be
treated, the device offers 6 air current flow levels (level 1 = 300
l/min, level 6 = 700 l/min.).
of the Cryo 5
In order to employ Cryo 5 in its entire capacity, the daily running
stages and principal elements should be understood.
The Cryo 5 is basically composed of the following elements:
- a "cold circuit" with a cold reserve,
- a compressor,
- a cooling fan (Fan C), situated in the low part of the unit,
- a therapy fan (Fan T),
- a defrosting system of the cold reserve,
- a micro-processor controlled driving system.
The daily running of the Cryo 5 consists of the following stages:
The Minimal Load
With "Load", we mean the time the device needs to produce a
certain quantity of cold that it will store in its reserve. The
"Minimal Load" of the Cryo 5 begins to be created as soon as the
device is switched on. This phase is characterized by the
simultaneous working of the compressor and the Fan C. These 2
elements are always functioning together. During the Minimal
Load, no functions are available and the indication displays only
bring a horizontal slash; no therapy is possible.
When the unit has reached its minimal cold temperature, the
Stand-By Indication Display (10) stops blinking. The compressor
and Fan C still function and now produce the Additional or Total
The Total Load
The Total Load refers to the steady maintenance of the maximum
cold temperature in the cold reserve.
For example: During a treatment (Starting of Fan T with the Start
Key), the compressor and the Fan C run automatically in order to
compensate for the loss of cold capacity. When the Fan T stops
(end of treatment) the compressor and Fan C will continue
running in order to complete the cold reserve.
During this loading period, treatment is possible. Afterwards, the
unit remains in Stand-By Mode.
If the device is not used for approximately 30 minutes, (in Standby Mode), the cold reserve will naturally lose part of its capacity.
The compressor and Fan C will then start running in order to
complete the cold reserve.
During the Stand-by Mode, treatment is possible.
Cold reserve additions are made automatically. The frequency
required to maintain adequate cold reserve may change
according to the climatic conditions around the Cryo 5.
for Optimal Use
The first treatment should be made after the cold reserve is
complete or Total Load and not after the Minimal Load.
Otherwise, the possibility exists that the unit may not have
enough cold reserve for subsequent treatments; it would then
automatically proceed to the Minimal Load and treatment would
not be possible for a few minutes.

Displays and Keys
(2a) Therapy Time
The therapy time can be adjusted with these 2 keys.
Any modification of the treatment time in Stand-By Mode will be
stored for the following treatments.

from 15 to 0 minutes.
, results in increasing the treatment time from
15 to 30 to 60 minutes.
During the Minimal Load or the Defrosting Phase, this display
does not indicate a treatment time, rather "--:--".
The therapy time is pre-set at 15 minutes, but is modifiable to suit
the user’s needs. During treatment, the time counts down by the
At the end of treatment, 00:00 is indicated in the Digital Therapy
Time Display. The end of the treatment is indicated by the stop of

This key has the following functions:
• In Stand-by mode or during additional loading, the treatment
begins by pressing this key. The treatment time counts down
by the second. During the treatment the compressor functions
• The treatment can be interrupted by pressing this key. The air
current flow and the therapy time stop.
• By pressing this key again, the interrupted treatment can be
continued. Therapy time starts again at the previous value.
• At the end of the treatment, Cryo 5 returns to Stand-by Mode.
All parameters return to their default value. The device can be
used again for a treatment.
Defrosting is made in Stand-by Mode by pressing both keys
simultaneously for a few seconds. Defrosting should be started
in 2 cases:
• When the air current flow of the Cryo 5 is lower than normal
(the cold reserve is blocked with ice and the air cannot
circulate freely. The cause of this is a very humid
• When the Cryo 5 will not be used for an extended period (i.e.
holidays), it is suggested to defrost the unit and to empty the
Water Container prior to leaving in order to prevent water
accumulation in the device.
During defrosting, the Stand-By Indication Display stops blinking
and the Defrosting Indication Display is lit. The device draws in
the ambient air, which passes through the cold circuit (without
being cooled) and draws it out through the treatment tube. The
defrosted water flows into the container at the back of the device.
The defrosting procedure stops automatically, once the
temperature of the cold circuit has reached ambient room
temperature, or manually by pressing both keys again. After
defrosting, the device proceeds to a Minimal Load.
It indicates that the defrosting procedure is running. Once
completed, the display stops blinking.
This indication display is lit when the Cryo 5 presents a defect in
the functioning. It is indicated by an acoustic signal and an error
number in the Digital Therapy Time Display: F --.
It is then better to switch off the device and call your distributor.
With the error number, he can give instructions on how to
This display indicates that the container for defrosted water
should be emptied. The container is accessible through the door
at the back of the device. When the indication display is lit, no
treatment is possible.
In order to protect the cold circuit and to control the purity of the
air drawn out of the Cryo 5, a filter has been installed (11) at the
back of the device. The indication display is lit when the filter
should be cleaned. Switch off the device and clean the filter with
After cleaning, the filter display must be switched off manually.
Proceed as follows: Hold the Start/Stop key pressed and switch
on the device.
(9) On/Off Indication Display
This display is lit as long as the device is switched on. If it should
go out along with the other indication displays, it is possible that a
malfunction of the Cryo 5 has occurred which burned out the
primary fuses of the device. In this case, please contact your
After-Sales-Service Representative, who will then check the
cause of the break down and change the primary fuses if
(10) Stand-By Indication Display
• When this display is lit, the Cryo 5 is ready for use; it has
enough cold capacity to proceed to treatments.
• When this display blinks, the Cryo 5 is proceeding to a
Minimal Load or defrosting. No treatment is then possible.
5. Description of the Back Panel
Upon switching on the Cryo 5, an acoustic signal sounds. The
device checks the correct functioning of keys and indication
displays in 2 ways:
- Graphic elements check
- Typical display check with treatment time and parameters.
Afterwards, Cryo 5 begins to store its cold reserve and all
displays indicate "--" until the device is ready for use.
(11) Filter for
In order to clean the treatment air of larger impurities, the Cryo 5
is equipped with a metallic filter at the back of the device. Its
maintenance is very simple: it should be cleaned regularly with a
vacuum cleaner. The operation must only be made when the
indication display for cleaning the filter is lit.
(12) Access Door
to the Container
By switching on the Cryo 5 or by starting "defrosting", the cooling
system warms and produces defrosted water. The Water
Container holding approx. 2 liters can be reached through the
door at the rear of the device. It can be opened by pushing the
black slide downwards.
It is advisable to disinfect the Water Container after emptying.
The level sensor (hanging ball) should also be cleaned. Check
before closing the door to be sure that the ball is placed in the
Water Container. The device should only be used when the
Water Container is placed in the unit.
