HEF7 series manual 32
Maintenance and cleaning
Humidifier components are very easy to maintain.
The following elements require maintenance:
The irrigation pump:
The most important thing is
to monitor to ensure dirt does not obstruct the
suction-
impulsion
circuit,
and
electricity
consumption is below the power rating on its
plate.
Control
valves:
These
must
be
inspected in accordance with their
mechanical regulation.
Solenoid valve:
This must be inspected in
accordance with its mechanical closure and
opening.
Metal filter:
This must be cleaned manually.
Evaporative panels:
For drinking and industrial
water supplies their operating life basically
depends on the constant bleed-off system for
mineral salts working correctly to prevent the
formation of lime deposits on surfaces. If it is not
regulated properly, the panels have to be replaced
in a short period of time, because the
air passing through the panels becomes blocked by
the formation of these deposits.
Water tank:
Elements holding bodies of still water
are renowned for generating microorganisms, and
algae. The maintenance director must implement
an inspection plan for emptying and cleaning the
HEF-7 pump tank based on the quality of the air
treated and the water supply.
Regular observations are recommended for correct
maintenance during the days following start-up, to
find out how the specific installation is behaving,
and to
establish the emptying and cleaning programme.
Similarly, during long periods of inactivity (summer in
the case
of humidification for comfort, and winter for
evaporative refrigeration) it is essential to totally
empty and clean the tank.
Evaporative humidifiers must be cleaned on a
regular basis to prevent their contamination. All the
surfaces of the components (panel, pipes and
especially the water tank) must be disinfected using
an appropriate solution.

Special attention must be paid to cleaning the piping system,
and above all the junctions.
In the case of the panels, the use of chemical disinfectants for
daily maintenance is not recommended because it could
reduce panel efficiency and the useful life. If it is necessary to
use chemical products, either because the system has
not been operational for a long time, or for any other reason,
an effective method is to submerge the panels in a chlorine
disinfectant, such as sodium hypochlorite (bleach) or
sodium percabonate. When using chlorine disinfectants, it is
essential to take into account the formation of toxic chlorine
gas if it is combined with an acid solution.
[Note]
Do not forget to employ the safety measures
of the manufacturer of the disinfectant solution.
