Water Quality Maintenance Start-Up - Master Spas Trainer 12 Owner's Manual

WATER QUALITY MAINTENANCE START-UP

For ECO PUR™ Water Filter System
Step 1: Your swim 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.
Step 2: During the initial filling of the swim 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, 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, total Alkalinity (TA) and Calcium hardness utilizing the directions on the chemical
bottles provided by your dealers start up kit.
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 oz. of concentrated chlorinating granules (sodium Dichlor-s-triazinetreone) per 500
gallons on initial start up to begin sanitizing the swim spa water. 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 the swim spa water.
* It may be necessary to rinse your filters within the first few days after filling your swim spa to ensure
that they are not restricting water flow due to the initial removal of heavy contaminents in source
water.
