If this is an initial certification or a recertification after HEPA filter
replacement, select
Reset Filter Gauge to 100%
. If this is an
annual recertification, select
Leave Gauge unchanged
. If you
want to set the filter gauge at a preset value, select
Set Gauge
to new setting
. Then press
OK/Mute
.

The Type A units with airflow sensor will ask you to now
calibrate the average downflow to match the value you obtained
when you measured it. After the downflow is calibrated, and you
press
OK/Mute
, the Logic+ will power down, and then restart
with the new settings.
13.
If the unit is a Type A without an airflow sensor, after the filter
gauge option is selected and you press
OK/Mute
, the Logic+
will power down, and then restart with the new settings. If the
Unit is a Type B2 or a Type A with an airflow sensor, you will
then be asked to calibrate the inflow sensor to match the value
you obtained when you measured the inflow. After the inflow is
calibrated, and you press
OK/Mute
, the Logic+ will power
down, and then restart with the new settings.
14.
For the Type B2, the unit will now ask you to reduce the
total
exhaust volume to 80% of the nominal value. When you have
done this, press
OK/Mute
.
This step is critical-it sets the alarm
point for the exhaust flow. If you press OK/Mute before reducing
the flow to 80%, the Logic+ will assume the alarm setpoint is
equal to the nominal airflow, and the unit will return an Alarm-
Inflow Screen.
The Logic+ will power down, and then restart
with the new settings. Be sure to reset the exhaust damper to its
nominal setting.
