Commissioning/Initial Start-Up
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 either the vacuum or the pressure 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 ¼ - ½ 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.
Initial Test Procedures
With breakers and power turned on, and pump running, check all alarms for proper operation:
•
Leak Detection - Manually raise the float switch located at the bottom of the leak-basin. Pump should
immediately turn off, and the “Leak Detection” alarm should be indicated on the System Controller. Reset the
alarm by pushing or selecting the “Alarm Reset” on the System Controller.
•
High Vacuum Alarm - Slowly, partially close inlet ball valve. At 12” HG, the pump(s) should turn off and the “High
Vacuum” alarm should be indicated on the System Controller. Open the inlet ball valve again. Reset the alarm by
pushing or selecting the “Alarm Reset” on the System Controller.
•
Water Sensor - Jump the Water Detection Sensor Probes water sensor probes by placing a piece of conductive
metal across the two horizontal contacts. The pump should turn off and the “Water Sensor” alarm should be
indicated on the System Controller. Remove the metal and reset the alarm by pushing or selecting the “Alarm
Reset” on the System Controller.
Note: If any of the above described alarm test procedures fail or if any alarm trip value deviates, immediately contact AXI
International.
