Recommended procedure for standard treatment
(settings 1 - 4)
The perception of odours is subjective. Besides, fluctuating
climate parameters such as the humidity level and room
temperature influence not only the diffusion of odour particles in
the room, but also the reaction potential for the oxidative
conversion of airborne odours and pollutants.
For this reason it is not possible to specify a linear reference
value e.g. depending on the room size. Instead we recommend
an individual, active levelling geared to the local circumstances
and your personal requirements:
1. Before the first application, air the room out thoroughly.
2. To begin with, set the ionizer to level 3 and the fan to
stage 1 and let the device run with these settings for up to
7 days.
3. During or at least at the end of the treatment there should
be either a perceivable reduction of the odour intensity
and / or a slight ozone odour.
If so, you can now turn the ionizer down by 1 level and, if
required, repeat this step according to your odour
perception until you have reached level 1.
4. If after a period of 7 days you cannot observe a reduction of
the odour intensity or an ozone smell, increase the
operating level one by one up to max. level 4 and treat the
room again for up to 7 days. Before using level 5 (intensive
treatment), first read the
Procedure for intensive treatment
.
Note:
•
Any time you reduce or increase the setting by one level,
wait for at least 7 days before making another change.
After every interval and before any level adjustment air the room
out exhaustively!
For the standard treatment the fan should be set to stage 1.
Procedure for intensive treatment
In case of considerable odour nuisance – e.g. from
long-lasting
sources
such as drains, fuel odours or the smell of mould or
intensive
one-time sources
like tobacco, animal smells or musty
odours in the car etc. – and if the previously performed standard
treatment was not successful, it is appropriate to carry out a
short-time intensive treatment at level 5 to effectively eliminate
the cause.
1. Make sure that all surfaces in the room to be treated are
freely accessible for the circulatory air of the DH-VPR+
(open windows, boot and bonnet of vehicles, open wardrobe
doors, shut the curtains to provide the best possible
effective surface). If possible, remove car mats and carpets
in the passenger compartment and boot and spread them
out on the floor of the garage. The better the air circulation
at the surfaces to be treated, the better the chances for a
successful odour elimination. To achieve optimum results,
the room temperature during the intensive treatment should
be in a range of 20 to 25 °C. This generally serves to ensure
a diffusion of the odorous substances. During the intensive
treatment the room temperature must not exceed 28 °C!
2. Set the ionizer to level 5 and the fan to stage 2 and let the
device run with these settings for 24 hours.
3. After this treatment period set the intensity switch from 5
back to a lower level and see to a thorough 15-minute
ventilation (rush airing) of the room. The ozone smell is
usually evaporated after 2 to 3 intermittent ventilation
processes.
4. If after the 24-hour treatment the reduction in odour
intensity is not satisfactory, repeat step 2 up to five times as
the circumstances require.
5. After a successful odour reduction repeat step 3 and
continue with the standard treatment (levels 1 - 4).
6. Also set the fan to at least stage 1.
Small amounts of ozone are generated within the device during
the intensive treatment. In the room air the ionizer does not
produce ozone concentrations exceeding the generally
applicable limit values. For reasons of safety and due to
individual sensitivities however, there must be no person or
animal present in the room to be treated. Entering the room as
well as brief visits to switch the device on and off are as
harmless as the short-term exposure to the ozone smell that is
sometimes subjectively perceived as intense.
Note:
•
If an ozone odour becomes noticeable in the room (not just
at the outlet opening) during the standard treatment,
gradually turn the intensity down until the smell is no
longer perceivable (Remember to air the room every time
you lower the intensity level).
