3.12.5 Caring for your COLDTUB
Pal System
Question 1 Does adding salt to the Tubs water impact pH?
Yes adding salt to the Tubs water will increase the pH level.
The chlorine that is produced by a salt chlorinator plays a role in the water chemistry of a salt
Tub. Salt is sodium chloride. When an electric charge is passed through salt water, the sodium
chloride is turned into sodium hypochlorite. This is the same kind of chlorine that is sold by the
gallon as liquid chlorine. The most important feature of sodium hypochlorite is a high pH. When
the salt chlorinator produces chlorine, it raises the pH of the Tubs water. Strive to achieve a Low
pH level 7.0. pH must not exceed 7.6.
Question 2 What do I do if my ORP Reading is below the Optimum Range?
If COLDTUB Pal reflects that the ORP is below the Optimum Range of 545 – 550 mV you must
first consider that water chemistry may have been affected by recent bather load and Tub usage,
at times the ORP value will overshoot or undershoot the Optimum Range.
If the COLDTUB Pal Dashboard on COLDTUB Pal reflects that the ORP is below 545 mV do the
following:
Check COLDTUB Pal Dashboard through COLDTUB Pal to see if the Dashboard reflects
sanitizing YES, if yes COLDTUB Pal is currently producing sanitizer. Re-check ORP in a few
hours to confirm ORP is increasing.
If Dashboard reflects Sanitizing NO:
Trip the Tubs breaker to isolate the power to the Tub and then turn the breaker back on to
repower the Tub.
Check COLDTUB Pal Dashboard through COLDTUB Pal to see if the Dashboard reflects
sanitizing YES, if yes COLDTUB Pal is currently producing sanitizer. Re-check ORP in a few
hours to confirm ORP is increasing.
If Dashboard reflects Sanitizing NO: Contact COLDTUB who will request a Master Technician
to log onto your Tub to determine the possible cause, such as depleted COLDTUB Pal Output
Electrode, Poisoned COLDTUB Pal Sensor or corroded COLDTUB Pal Output Electrode
electrical connections.
