SPA FROG ®
In-Line System
Operating Instructions

Please read the product label and attached leaflet before using it.
This hot tub in-line system contains two parts:

A bromine cartridge for disinfection
And a conditioning cartridge for softer feeling water.

Hot Tub Start-Up

Always drain and refill the spa at least every 4 months.
Clean and replace filter cartridges when dirty
(Follow manufacturer’s instructions).
Balance water according to the chart.
WATER BALANCE GUIDELINES

pH:| 7.2 – 7.8
Total Alkalinity:| 80 – 120 ppm
Calcium Hardness:| 150-250
Total Dissolved Solids:| <1500
Free Bromine:| 3.0 – 5.0 ppm
Heat water to recommended temperature before using cartridges.
Very Important! Before using cartridges, establish an initial residual of 3.0 – 5.0 ppm bromine or chlorine with a granular brominating concentrate (which typically contains 85% sodium dichlor (chlorine) and 15% sodium bromide) OR a chlorine shock.
DO NOT use a non-chlorine shock.
Begin Regular Hot Tub Care procedures (see page 5) as soon as the start-up is complete.

Setting Cartridges

Set the blue Conditioning Cartridge to wide open on #6 by holding the bottom and turning the top until the number 6 appears in the setting window.
No further adjustments are necessary.

Replacing Cartridges

| The SPA FROG Conditioning Cartridge should be replaced every 4 months or when draining and refilling the spa with fresh water.
---|---
| Replace the SPA FROG Bromine Cartridge when empty. Drain water to ensure the cartridge is empty then discard it in the trash. The cartridge life will vary depending on hot tub size and the number of users.

Regular Hot Tub Care

Run filtration system as recommended by your hot tub manufacturer.
Regularly test the water with test strips for pH, total alkalinity, and bromine levels.
Maintain a 3.0 – 5.0 ppm bromine level at all times.
Shock the hot tub once a week or as needed. Additional shocking may be required if the hot tub is under heavy use. This is often the case when the hot tub is new.
Remember to replace SPA FROG Conditioning Cartridge and SPA FROG Bromine Cartridge as directed under “Replacing Cartridges.”
