Frequently Answers and Questions
How do I select the mode of operation for the PTS-ISU?
The PTS-ISU has three modes of operation: OFF, CONT (continuous), and INT (intermittent). To select the mode, simply turn the mode selector switch to the desired position.
How do I set the suction level on the PTS-ISU?
To set the suction level, first push the suction control knob in. Then, rotate the knob clockwise to increase suction or counterclockwise to decrease suction. The desired suction level will be displayed on the gauge.
What are the timing cycles for the PTS-ISU's INT mode?
The factory settings for the INT mode are 15 seconds ON and 8 seconds OFF. You can adjust these timing cycles using the timing valves on the back of the unit. To increase the ON time, turn the ON timing valve clockwise. To decrease the ON time, turn the ON timing valve counterclockwise. To increase the OFF time, turn the OFF timing valve clockwise. To decrease the OFF time, turn the OFF timing valve counterclockwise.
