10. PREVENTIVE MAINTENANCE
Although maintenance operations are not usually complicated, we recommend that they
be carried out by qualifi ed personnel. At S&P we have an extensive network of Technical
Services that will be able to offer technical assistance for both equipment startup and fi lter
maintenance and interior cleaning of the unit. On our page www.solerpalau.com you will fi nd
information about the Technical Services that cover your region.
10.1. FILTERS
PAP purifi ers equip absolute fi lters with a fi ltration effi ciency of ≥99,995%. In order to enjoy
the purifi er's performance for a long time, it is essential to properly maintain the fi lters.
Filter handling considerations
The PAP-420 units have two fi ltration stages of F7 + H14. In the case of PAP-350 units, they
have a third specifi c stage for the elimination of odors, gases and VOC (depending on version).
Depending on the environment in which PAP purifi cator was used, the dirty fi lters could con-
tain a large number of particles and polluting substances and / or toxic.
In the case of odor, gas and VOC fi lters, the adsorbent material contained in the fi lters has
a high adsorption capacity for contaminating gases, while HEPA H14 fi lters have a very high
effi ciency for the retention of viruses and bacteria.
When perform the manipulation of used fi lters, follow these recommendations:
• Protect yourself with a FFP-2 or FFP-3 mask and wear disposable gloves during the ma-
nipulation of the fi lter.
• Minimize contact time with fi lters.
• Once removed, deposit the fi lters in hermetic plastic bags and contact a professional with
a Waste Manager qualifi cation to treat the fi lters according to the procedures established
in your community.
Cleaning and replacing of fi lters
F7 pre-fi lter
It has the function of retaining the largest particles and at the same time protecting the rest
of the fi lters, extending their useful life. A visual check of the F7 fi lter should be carried out
periodically.
Cleaning of the pre-fi lter should be done gently to avoid damaging the fi lter material. With the
help of a dry or slightly damp cloth (never wet), remove the particles accumulated on the fi lter
surface, lint, dust accumulation and larger particles.
Do not blow with compressed air neither use vacuum cleaners, as in both cases the fi lter
element could be damaged, considerably reducing the effi ciency of the fi lter.
H14 absolute fi lter and odor, gas and VOC fi lters
These fi lters do not need maintenance. Once the fi lters have been clogged, they must be
replaced.
The maintenance frequencies of the fi lters will depend on several factors such as the hours of
use, airfl ow of regulation, as well as the degree of cleanliness of the environment. Due to this
factor dependence, it is not possible to establish exact maintenance frequencies. As a guide,
the following guidelines can be followed:
• Visual check / pre-fi lter cleaning: Every 2 months.
• Pre-fi lter replacement: Between 6 months and 1 year depending on use.
