Water Filter System

Step 1: Your spa should be filled using a Pre-filter, which can be obtained from your local

dealer. This Pre-filter will help remove many of the minerals existing in the water,

which will make adjusting the water balance easier after a new fill. Never use more

then 50% softened water when filling the spa.

Step 2: During the initial filling of the spa, add a sequestering agent to combat suspended

minerals in the water. The agents are sold under many different names such as Mineral

Clear, Stain and Scale, Metal Protect, and other brands. Allow water to circulate and

filter for at least 12 hours before adding any other chemicals.

Step 3: Test water for pH, total Alkalinity, and Calcium hardness. The pH should be 7.2 - 7.8

and the total Alkalinity 80-150 PPM. Calcium hardness levels should be maintained

between 150 and 250 PPM (part per million).

Step 4: Adjust pH and total Alkalinity (TA) utilizing the directions on the chemical bottles.

Wait 15 minutes, test and adjust if necessary.

Step 5: It may be necessary to retest and add additional chemicals to get to the proper levels

in Step 3.

Step 6: Add 2 ounces of concentrated chlorinating granules* (sodium Dichlor-s-triazinetreone)

on initial start up to begin sanitizing the spa water. Always refer to the chemical manu-

factures dosage recommendations listed on the container. It is important not to add

the chlorinating granules until the pH, alkalinity and calcium hardness have been

adjusted to their proper levels.

*SPECIAL NOTE:

We recommend a minimum level of 1.0 ppm residual chlorine be maintained in spa water. Always refer to the

chemical manufacturer’s dosage recommendations listed on the container.

When adding chlorine or non-chlorine shock/oxidizer always broadcast across the water while the pumps are

running.

The quantities of sanitizer and oxidizer shown in this manual are for 500 gallon spas and may have to be adjust-

ed depending on the actual amount of water that your spa holds. See the specifications section of this manual

for the correct gallons of your spa.

The concentration of active ingredients in spa chemicals varies by manufacturer. The amounts of sanitizer sug-

gested in this manual are based on spa chemicals that have the active ingredient percentages listed below:

Chlorine Non-Chlorine Shock/ Oxidizer

Sodium dichlor ................................. 99% Potassium peroxymonosulfate ....................... 42.8%
