FreshWater Salt System
English
No Chlorine Reading
The system cleans spa water differently than manually added chlorine. If there appears to
be no chlorine in the water:
• Check output level
. Check 10-day timer. If you are using the spa frequently/
daily or have the Summer Timer on, you may need to increase your output level.
• Shock.
If during the initial start-up process, shock daily until a minimum 3 ppm
chlorine residual is being maintained.
• Consult your dealer
about changing the internal system output level.
• Cyanuric acid lock
. If you add dry chlorine to shock or supplement your water
and your chlorine reading is back to 0 (zero) ppm, it is possibly your salt system
is reacting to your specific water chemistry or metal content and is being inhibited
by the cyanuric acid from dry chlorine. Consult your dealer about switching to
un-stabilized liquid chlorine (sodium hypochlorite) to correct and stabilize your
water chemistry.
• Remove phosphates
. Test and manage phosphate levels.
IMPORTANT
Shock the spa water with chlorine at start-up. Skipping this step can prevent
the system from establishing a chlorine residual.
If the system is running at the maximum output level and still cannot keep your
chlorine in range, consult your dealer.
High Chlorine
The system will continue to produce chlorine according to the selected output level,
regardless of whether you use your spa or not. If you begin to use your hot tub less
frequently, it is important that you lower the output level.
If the chlorine level is too high:
• Check output level.
You may need to decrease the output level to a lower
number.
• Reduce chlorine.
Add 1 cup (240ml) hydrogen peroxide with jets running.
Check chlorine level after 10 minutes and repeat as needed.
• Consult your dealer
about changing the internal system output level.
Tips
• Calcium Hardness:
Use the FreshWater Vanishing Act Calcium Remover to
keep total calcium hardness levels low and minimize the need for antiscalant
or liquid metal control products. An On The Go portable water softener is
recommended for high calcium hardness areas.
• Heavy Use:
Initiate a Boost cycle a few hours prior to heavy use. Periodically test
the chlorine and add chlorine as needed.
• MPS Use:
Granular Monopersulfate (MPS) can be used in place of chlorine to
establish a sanitizer residual at start-up and for shocking the spa.
Use FreshWater MPS Test Strips to measure MPS levels in the spa water if MPS
is preferred.
NOTE:
MPS and MPS test strips are sold separately.
