3c. Changing air pressure in air hose
Reroute air hose.
1. An air button with ruptured seal or bellows inside, will
not produce sufficient air pressure to operate the
momentary air switch and could lead to total
break-down.
2. Water in air hose will damage the pulse switch and it is
caused by a faulty air button (see note 1above) 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 relay is either due to contact or coil failure.
Contact failure is caused by over-load 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 2 above) or spa cover
placed over (and depressing) the air button. In any case,
the cause must be found, corrected and the relay replaced.
