38 North American 60Hz Installations: As of January 1, 1994, the National Electrical Code (NEC) requires a Ground Fault Circuit In- terrupter (GFCI) on all hot tub installations in the US. A GFCI must be wired correctly or it will trip. Make sure the electrician has wired the GFCI according to the diagrams on page 52. 8.6 Hot T ub Light Will Not Co[...]

39 8.7 No Jets This is a condition of constant zero water pressure. The  rst step in diagnosing the problem is to determine if the pump is actually turning. Once this determination is made, follow the appropriate portion of this S.T .A. Diagnostic T ools: V oltmeter , spare control panel. Suggested Spare Parts (Page 59): Control panel, circuit b[...]

40 8.8 Weak Or Surging Jets Weak or surging jets are usually caused by an insuf cient water supply to the pump or a clogged or broken impeller . The water level may simply be too low , or there may be an obstruction in the water  ow path to the pump or in the pump’s impeller . Before making a service call, ask the customer to verify that al[...]

41 8.9 Pump Runs And Quits During Jet Mode This is usually a problem of the pump overheating. The pump motor incorporates a ther- mal cutout that triggers when the motor gets too hot. There is no reset for this condition. When the motor cools, the thermal switch resets automatically . In some cases, a faulty circuit can also cause this problem. Dia[...]

42 8.10 Circulation Pump Not Working The circulation pump should be on for the programmed duration each day and for a heat call unless “Summer Logic” is activated. V erify the pump should be on before trouble- shooting. Check the circulation pump start time and duration setting. Refer to section 5.6C (page 23). Diagnostic T ools: Clamp-on ammet[...]

43 8.1 1 T roubleshooting A Thermal Pump Cutout 1. 2. 3. 4. V erify that the voltage to the hot tub is 240 V AC (120 or 240 V AC for J-315, J-325) ±10%. An insuf cient voltage supply can cause the motor to pull too much current and to overheat. This situation must be corrected. Check the voltage to the hot tub. Remember , the power company is r[...]

46 A1.0 Checking V oltage T o Hot T ub Correct supply voltage wiring to the hot tub is essential for safe/proper operation. The  rst step in troubleshooting a new installation should be to take voltage readings at the terminal block TB1. Do not trust wire colors. Electricians make mistakes and electrons are colorblind. A low line voltage or inco[...]

47 A2.0 Checking V oltages T o Devices Device voltages are often measured at the circuit board to determine whether the board or the device is bad. If the circuit board delivers voltage when the device operation is called, the circuit board is prob- ably good and the problem lies with the device or the wiring to the device. The following voltage ch[...]

48 A4.0 T esting The Flow Switch When the “FL1” or “FL2” message appears, it means the  ow switch contacts have failed to close when the circulation pump was on, or failed to open when the circulation pump was off. This could be caused by an obstruction in the  ow path or by a bad switch. The  rst thing to look for is an obvious ob[...]

49 A7.0 Understanding Ozone Oxygen is an element, and like other gaseous elements, normally exists as a pair of atoms bonded together to make a whole molecule. Chemists therefore use the symbol O 2 to speak of “oxygen mol- ecules” rather than oxygen atoms. In the presence of an electric discharge like lightning or a strong source of ultraviolet[...]
