TOPSIDE CONTROL OPERATING 
INSTRUCTIONS(Continued) 
Air Jets button (if equipped) 
The topside control button designated “AIR” activates the air blower when pressed. The air blower, 
when  the  “AIR”  button  is  manually  pressed,  has  a  20  minute  time-out.  If  the  “AIR”  button  is 
pressed again prior to the completion of the 20 minute time-out, the air blower will be deactivated 
and the time-out will reset. When the air blower is in operation, the LED “AIR” is illuminated. 
Changing The Filter Cycles/Water Filtration 
Proper filtration is an important key to maintaining the clarity of your spa’s water. The filter system 
is designed to remove debris and particles from the water when the water is circulating. 
The system has seven programmable filtration cycles. The default from the factory is 2 hours on 
10 hours off. To enter the filter cycle change mode, the user must press and hold the   button 
for five seconds until one of the following messages is shown on the LED (topside control) read- 
out: 
(2-9) (On 2hours/Off 10hours); displays 9 instead of 10 only “3” digits on the readout. 
(2-6) (On 2hours/Off 6hours); 
(2-4) (On 2hours/Off 4hours); 
(2-2) (On 2hours/Off 2hours); 
(4-2) (On 4hours/Off 2hours); 
(6-2) (On 6hours/Off 2hours); 
On (On All the time); Pump runs continuously 24 hours a day on low speed. Used for extreme 
cold weather. 
After entering the filter cycle change mode (see above), the user presses the         buttons to 
select the desired filter setting. The system display will return to normal after five seconds if the 
buttons have not been pressed. 
During a filter cycle, the  
Jet 1   
 flashes on the topside control. When either the high speed pump or 
the  blower  (if  equipped)  is  turned  on  during  a  filter  cycle,  the  filtration  cycle  will  stop  and  will 
resume on the next filtration cycle.
