chosen, press the Enter key to store the new High
Pressure setting into memory. Press the Down Arrow

Odorant Inlet Pressure Monitoring
For the fill valve to function correctly a pressure differen-
tial between the Bulk Odorant Storage Tank and the
Expansion Tank, must be maintained. This differential
should never be less than 5 psi (.35 Bar) and typically
not more than 10 psi (.69 Bar). There are two alarms
that may be triggered from the Odorant Inlet Pressure
reading, a High Odorant Inlet Alarm, and a Low Odorant
Inlet Alarm.
To set the alarm level points, figure 48, press and
release the Select key. The Odor Inlet Low value will
begin to flash when chosen. Nominal low pressure in
the Odorant Storage Tank is 30 psi (2.07 Bar). Use the
Up Arrow key to increase the value and the Down
Arrow key to decrease the value. When a new value
has been chosen, press the Enter key to store the new
Odor Inlet Low setting into memory. The entered value
will stop flashing when it has been loaded into memory.
Next the Odor Inlet High value will begin to flash.
Nominal high pressure in the Odorant Storage Tank is
35 psi (2.41 Bar). Use the Up Arrow key to increase the
value and the Down Arrow key to decrease the value.
When a new value has been chosen, press the Enter
key to store the new Odor Inlet High setting into
memory. Press the Down Arrow key to advance to the
next menu.
