SYMPTOM
1. Equipment will not operate.
2. Equipment will not turn off.
3. Equipment turns on/off
by itself.
NOTES:
1. An air button with a ruptured seal or bellows inside, will not produce sufficient air pressure to operate the pulse air switch and
could lead to total breakdown - see note 3.
2. Water in the air hose is caused by a faulty air button (see note 1 above) or condensation. In either case it must be drained
and the cause found and corrected. To reduce condensation, protect the air hose from exposure to direct sun, ice or frequent
temperature fluctuations.
3. A defective air switch is the likely result of water in the air delivery system (see note 2 above). A permanently closed air
switch (due to water) will energize the alternate action relay coil permanently thus causing the coil to overheat. It is therefore
good practice to check and replace, if necessary, other components (such as air button, air switch and relay) in order to
correct the fault.
4. A defective relay is either due to contact or coil failure. Contact failure is caused by overload or cross-wiring and coil failure
is caused by 240 volt connected across the 120 volt coil or permanently applied 120 volt. (The relay is designed for
intermittent duty only.) Permanently applied 120 volt could be the result of water in the air hose (see note 3 above) or a spa
cover placed over (and depressing) the air button. In any case, the cause must be found, corrected and the relay replaced.
