Water Care
IMPORTANT: Caring for your water by ensuring proper chemical
usage is the single most important thing you can do to keep your
Coast Freshe in good condion.
WARNING: Improper chemical usage and maintenance will quickly
lead to severe issues with your Coast Freshe and can aect the
equipment, jets, pumps, and all other components in contact with
the water. All Coast Freshe are suscepble to damage from
unbalanced water.
Always maintain your water chemistry within the following
parameters.
pH 7.2 - 7.8
Chlorine 1.0 - 3.0 ppm
Bromine 2.0 - 5.0 ppm
Total Alkalinity 100 - 120 ppm
Calcium Hardness 150 - 250 ppm

MAINTENANCE PROCEDURES
CHANGE YOUR FILTER.
(EASIEST TO DO WHEN EMPTY). IF FULL, FOLLOW
INSTRUCTIONS BELOW:
1. Turn off the power before replacing the filter.
2. Turn off the ball valve by rotating it clockwise.
3. Using the filter wrench, loosen the filter canister by
rotating it clockwise.
4. Remove the filter canister and discard the old filter.
5. Clean the filter canister and replace the filter.
6. Turn on the ball valve by rotating it
counterclockwise.
BI-ANNUALLY OR AS NEEDED
DEEP CLEAN PLUMBING
1. Hot water must be used to deep clean the
plumbing.
a. Hot & Cold Plunges can be turned to 104
degrees.
b. Cold Plunges will need to use an immersion
heater.
2. Put in a teaspoon of plumbing and jet cleaner
(e.g. Whirlpool tub clean).
3. Let the system run for at least 30 minutes.
4. Drain and refill.
MAINTAINING WATER CHEMISTRY
Initial set-up
1. Fill up the cold plunge with distilled or tap water. If
the water contains mineral levels such that calcium
deposits (scale) frequently build up on and around
your faucets, it is recommended to use a prefilter.
2. On initial fill up, no chemicals are required since the
water is fresh out of the tap. Chemical treatment of
the water will begin after the first use or after two
days (whichever comes first).
**Note: Before using the Coast Freshe, it is highly
recommended to shower with hot water without the use
of any soaps and rinse bathing suits with hot water as
well. This is to ensure the removal of any creams, lotions,
soaps, oils, make-up, detergents, deodorant, etc. so that
these residues do not leach into the Coast Freshe water.
Following this step before using your Coast Freshe will
ensure a more enjoyable experience, it will increase your
ease of water maintenance significantly, and keep your
water fresher for longer.
Steps for adding balancing chemicals:
1. To test the water, quickly dip a test strip into the water
and pull it out to observe the colour change on the
strip, the colour change takes 5-10 seconds with cold
water.
2. Start by assuring the alkalinity is approximately 100-
120 ppm. To increase the alkalinity, add Alkalinity
Booster in ½ cap increments and stir the water to
make sure it dissolves.
3. Once the water alkalinity is around 100-120 ppm,
check the pH and make sure it’s somewhere in the
range of 7.4 – 7.8. To increase the pH, add pH UP in
¼ cap increments and to decrease the pH, add pH
DOWN in ¼ cap increments. It’s important to add pH
chemicals in small increments to assure you achieve
the 7.4 - 7.8 range.
Steps for sanitizing the water:
1. Once the water is balanced (alkalinity 100 – 120 ppm,
pH 7.4 – 7.8), then it’s ready for sanitizing. Add ¼ cap
(approximately 1 tbsp) of Harmonize after using the
Coast Freshe, stir the water to assure the sanitizer
dissolves and leave the cover open for 15 minutes to
allow the chlorine to off-gas.
2. Maintain the Coast Freshe sanitizer (chlorine) level
around 0.5 – 1 ppm when using. This will minimize
skin irritation and allow for a better experience.
