For best results, read each step in its entirety before proceeding with that 

step.

1. 

Clear all debris from the spa. (Although the spa shell has been 

• 

polished at the factory, you may want to treat it with a specially 

formulated spa cleaner.) Consult your authorized Jacuzzi dealer for 

additional information prior to filling spa.

Remove filter cover, then remove filter cartridge as outlined in 

• 

2. 

Place the end of your garden hose into the empty filter bucket.

Never fill with water from a water softener. If your water is extremely 

“hard”, it is preferable to fill half-way with hard water and the rest of 

the way with softened water. Water that is too soft can be corrosive 

to metal components.

Fill hot tub with clean tap water from garden hose, to reduce risk of 

contracting a waterborne illness (e.g. an infection, bacteria or virus) 

and/or respiratory ailments. Fill until water covers all jets but does not 

touch the bottom of the lowest headrest. (DO NOT OVERFILL!)

ImporTanT: Always fill your spa through the filter bucket after 

draining. Failure to do so may cause air to be trapped in either 

pump, preventing the pump from circulating water. Remove the 

hose and replace the filter cartridge. Note: DO NOT overtighten 

filter cartridge, finger tight only!

3. 

Turn on power to spa at the home’s circuit breaker to start boot 

up sequence (Sec. 10.0, page 25). The heater and filter pump will 

automatically activate after several seconds. If the control panel LED 

flashes water temperature and “COL” or “ICE” this is normal, refer to 

page 38 for additional information.

4. 

Turn on jets pump(s) to ensure proper mixing when adding 

start-up chemicals in step 5.
