Acoustic Cleaning Technical Advice

Instructions for adjusting the Timer Model 1078 (PSI Ref: ASA111 and 112)

1. Please have both the timer and instruction leaflet in front of you.
2. Setting the correct on/off function. This refers to switches no 4 and 5 on the bank of 8 switches. Both these switches 4 and 5 should be in the down position.
3. Set the duration of activating the solenoid to operate the acoustic cleaner. This refers to switches 1, 2 and 3 and also the small blue pot on the bottom left-hand side of the timer. Let's say we are going to set a duration sounding at 10 seconds. If you look at the leaflet under "t'on" look at that column, third one down, you will see on the left-hand column of the figures that this is used to set the duration of between 5 seconds and 100 seconds. In this case switch 1 should be down, switch 2 up and switch 3 down. This gives the general "duration" time range and to fine tune this we adjust the pot on the bottom left of the timer. This pot rotates through 270º, turning clockwise increases the length of sounding, turning it anti-clockwise decreases the length of sounding, therefore the pot should be turned until the sounding of 10 seconds is obtained and the duration of sounding the acoustic cleaner is therefore set.
4. Now we move on to setting the interval between soundings of the acoustic cleaner and this involves switches 6, 7 and 8 and also the small blue pot at the bottom right of the timer. Let's say we are setting the interval period for 7 minutes. This is the fourth line down on the "t'off" switches. You can see this ranges from 0.5 minutes up to 10 minutes therefore switch 6 down, switch 7 up and switch 8 up. This gives the general interval "time range". Then we adjust the small blue pot at the bottom right-hand side until we reach an interval period of 7 minutes.

Instructions for adjusting the Timer Model TEC 22 (PSI Ref: ASA119)

1. Please have both the timer and instruction leaflet in front of you.
2. Setting the correct on/off function. This refers to the two rotary switches set on the front control panel of the timer.
3. Set the duration of activating the solenoid to operate the acoustic cleaner. This refers to rotary switch on left-hand side with the units in seconds. Turn the rotary switch so that the arrow is pointing at the number of seconds you were advised to sound the Primasonics® cleaner for.
4. Now we move on to setting the interval between soundings of the acoustic cleaner and this involves the rotary switch on the right of the control panel with units in minutes. Turn the rotary switch so that the arrow is pointing at the number of minutes you were advised to have the Primasonics® cleaner off for. The operation of the unit can be tested at any point by pressing and holding down the button marked TEST.
