RECOMENDED VALUE FOR SETTING H14 PRESSURE SWITCH
Definition of the pressure switch value Filter change warning switch H14, knowing
that this limits the flow that the machine gives:
·
If the unit is installed without ducts, the H14 pressure switch is set at about 175 Pa and
the machine should not drop below 235 m
3
/h; initial flow of 325m
3
/h with pressure
differential of H14 of about 120Pa.
Switch delta = 55Pa
·
If the unit is installed in a duct system about 50Pa (the sum of impulse and suction), it
should be set at about 150Pa and the machine would not drop below 210Pa;
initial flow of approx. 290 m
3
/h with differential pressure in the H14 starting at 105Pa;
Switch delta = 45Pa
·
If the unit is installed in a 100Pa duct system, the pressure switch should be set to
about 135Pa and the machine would give at least 180m
3
/h; initial about 260m
3
/h and
pressure difference in H14 of initial 95Pa.
Switch delta = 40Pa
5.2 SETTING-UP LOCATION
Avoid installing the device in areas close to heat sources and humid areas where the it
may come into contact with water.
It is advisable to place the device in a location where the installation is easily accessible.
Provide sufficient space for maintenance and connection.
5.3 MAINTENANCE SPACE
The person installing the equipment must allow space which is free of obstruction
to be able to freely access the device for maintenance. The space required will
depend on the side of the device where the extraction is made. The equipment is
provided with registers to access the filters and fans.
