Gauge Venting
After shipment, gauge pointers may not rest at zero due to internal case pressure build-up, which is caused by
temperature and/or pressure variations. As a result, their accuracies may be significantly reduced. To restore the gauges
to operating condition, move the yellow lever of the fill plug to the open position or remove the black rubber piece from top
of gauge and leave it open to vent.
Switch Adjustments
Note: Please contact AXI International before adjusting the vacuum switch to avoid voiding the system’s warranty.
Vacuum Switch
When the value exceeds the set point of the switches’ rating, the switch will change state. Ensure you are working with a
normally closed position (leads on opposite sides of the switch – across from one another are connected to the wire
spades). If the set point is incorrect, adjustments can be performed in the field as follows:
1.
Remove the two wires connected to the normally closed spades on the top of switch.
2.
Pop off the “Rubber Plug” in between the spades on top of the switch.
3.
Insert a 5/64” Allen Wrench/Key into the slot.
4.
Adjust the Wrench/Key

turn at a time CCW to increase the vacuum alarm’s set point.
5.
After adjusting the settings, perform the testing procedure(s) for the switch(es) as outlined in the commissioning
section.
Flow Switch
When the flow rate drops below the predetermined set point on the flow switch, the switch will trigger a signal to shut
down the pump. The Set Point (SP1) on the flow switch should be set at the nominal flow rate of the system. There is also
a Reset Point (rP1) which should be set to 5% less than the SP1 setting. If the set point is incorrect, an adjustment can be
performed in the field as follows:
1.
Status Indicator 1
2.
Flow Rate and Temperature Indicators
3.
Status Indicator 2
4.
Alphanumeric Display
5.
Up/Down Directional Arrows
6.
Selection Button
1.
To change the Set Point (SP1), press the Selection Button to display the current SP1 setting.
2.
Press the Selection Button again, Status Indicator 2 should be illuminated and a GPM value will be displayed.
3.
Hold the Up Directional Arrow for 2-3 seconds, then use the Up and Down Directional Arrows to change the SP1
value.
4.
When finished, press the Selection Button to store that value as the adjusted Set Point (SP1).
5.
To change the Reset Point (rP1), press the Selection Button to display the current SP1 setting and then press the
Down Directional Arrow to display the current rP1 setting.
6.
Press the Selection Button again, Status Indicator 2 should be illuminated and a GPM value will be displayed.
7.
Hold the Up Directional Arrow for 2-3 seconds, then use the Up and Down Directional Arrows to change the rP1
value.
