START UP STEPS
1.
Your spa should be filled with fresh tap water using a Pre-filter, which can be obtained from
your local Master Spas 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.
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 or
Metal Protect. Always follow the instructions listed on the bottle and allow water to circulate
and filter for at least 30 minutes (or per bottle recommendations) before adding any other
chemicals.
3.
Test water for pH, total Alkalinity, and Calcium hardness. There are two different methods you
can use to test your water.
TEST STRIPS:
The pads on these thin strips react by changing colors when you dip them in
the hot tub water. To avoid faulty test results, use care when removing a testing strip from
the packaging. Open the package and shake one strip out into your hand, avoiding contact if
possible with the remaining strips. Seal the container immediately so the remaining strips are not
exposed to moisture. Dip the test strip into the water and follow the instructions supplied with
test strips as instructions may vary. Note the colors on your testing strip and compare these to
the key found on the packaging to determine whether elements are neutral, too high or too low.
TESTING KIT:
When using a testing kit, you will be examining an actual water sample from your
hot tub, rather than a strip. Be careful to follow the instructions on your kit, filling the container
to the appropriate level and then dropping the instructed liquid into the container. Compare
the new color of your water to the key provided with the kit to determine how to proceed.
Depending on which kit you purchase, it can test for each one of these elements: total alkalinity,
pH, chlorine, bromine and calcium hardness.
4.
Adjust pH and total Alkalinity (TA) utilizing the directions on the chemical bottles. Wait
15 minutes, test and adjust if necessary.
5.
It may be necessary to retest and add additional chemicals to get to the proper levels.
6.
Add concentrated chlorinating granules (sodium Dichlor-s-triazinetreone) on initial start up to
begin sanitizing the spa water, according to directions on chemical bottle. Bathers should not
enter the spa until the chlorine drops to a safe level, refer to Water Chemistry Guide in this
section. It is important not to add the chlorinating granules until the pH, alkalinity and calcium
hardness have been adjusted to their proper levels.
NOTE:
See the Model Specifications section of this manual for the correct gallons of your spa, to ensure
you are adding the correct amount of chemicals. When adding chlorine or non-chlorine shock/
oxidizer always spread it across the water while the pumps are running. The concentration of
active ingredients in spa chemicals varies by manufacturer.
