The high concentration of chlorine gas which may exist as a result of super chlorination (not daily sanitation) may eventually cause discoloration or
degradation to the bottom of the cover or the tile grouting, which would not be covered under the terms of your limited warranty.
WARNING: Always allow the Free Available Chlorine to fall to 5 ppm before using the hot tub.
WARNING: Never leave an open hot tub unattended, especially if there are children present!
BUILDING A SANITIZER ROUTINE
During the first month of ownership, measure the sanitizer residual daily in order to establish standards for User Load and Usage Time versus
Sanitizer Needed.
• The User Load of the hot tub is the number of times anyone enters the hot tub.
• The Usage Time is simply the amount of time a user spends in the hot tub.
• Sanitizer Needed is the amount of Free Chlorine Residual needed to accommodate the number of users and their combined usage time.
For example, two hot tub users who regularly use the hot tub once an evening for twenty minutes create a specific and somewhat consistent
demand on the sanitizer. During the first month of ownership, these two users can determine exactly how much sanitizer to use in order to
maintain the proper residual. If, at any time, the user load and/or usage pattern changes dramatically (invited guests), the amount and frequency of
sanitizer required increases dramatically.
The greater the usage time or the user load, the faster the residual value is diminished.
SUPPLEMENTAL WATER MAINTENANCE
Proper water sanitation and mineral balance (pH control) are absolutely essential for a complete hot tub water maintenance program. Here are
three other popular water additives that are optional:
Mineral Deposit Inhibitors
As water evaporates from your hot tub and new water is added, the amount of dissolved minerals will increase. (Minimize evaporation by keeping
the cover on the hot tub whenever possible.) The hot tub water may eventually become "hard" (Calcium Hardness too high) enough to damage
the heater by calcifying its surface. Proper pH control can minimize this.
Normal soap build-up will require water replacement regularly enough that mineral deposits normally are not a problem.
Occasionally, high iron or copper content in the water may produce green or brown stains on the hot tub. A mineral deposit inhibitor may help to
reduce these metals.
NOTE: Well water may contain high concentrations of minerals. The use of a low water volume, extra-fine pore water filter (in-line pre-filter such as
®
the FreshStart pre-filter) will help to remove many of the larger particles during the filling of the hot tub. In-line pre-filters can be purchased at
10,000
™
your local Limelight dealer.
Foam Inhibitors
Hot tub water requires changing due to the buildup of soap in the water. Typically, soap will cause the hot tub water to foam when the jets are
used. Soap is introduced into the hot tub water from two sources: users' bodies, which retain a soap residual after showering, and swimming
apparel, which retains soap after washing.
Foam inhibitors can suppress foam, but cannot remove soap from the water. Soap is very difficult to remove from the water because soap is not
oxidized by any chemical added to the hot tub. Only ozone can oxidize soap.
Eventually the soap build-up in the water will be concentrated, resulting in an unclean feeling on the bather's skin which is impossible to remedy.
When this occurs, it's time to drain and refill the hot tub. Depending on the soap input, the water should last about four months before needing to
be drained.
Ozone
(OPTIONAL EQUIPMENT)
Ozone is a powerful oxidizing agent which is produced in nature, and artificially by man. Ozone will oxidize a wide range of water contaminants,
from soap residue to bacteria.
®
The FreshWater III high-output ozone system is the only ozone purification system approved for installation in your Limelight hot tub. The
FreshWater III ozone system features Corona Discharge (CD) technology to produce a higher concentration of ozone than is produced by
competing ultraviolet light (UV) ozone systems.
The under-the-cabinet mounted FreshWater III high-output ozone system offers less-visible installation and is less susceptible to the effects of
freezing temperatures. To access it for inspection, remove the equipment compartment panel to check the unit operation (this is usually done prior
to disconnecting the power to the hot tub before draining).
The FreshWater III high-output ozone system greatly enhances the quality of the hot tub water when used to supplement the hot tub owner's
regular water maintenance program. Contrary to some information circulated throughout the pool and hot tub industry regarding ozone systems,
ozone CAN NOT be used as a single-source sanitizer, water clarifier, anti-foamer, and mineral chelating agent. A secondary source sanitizer must
be used to maintain 2.0 ppm (2.0 mg/L) of Free Available Chlorine (FAC). Watkins Manufacturing Corporation recommends that a chemical
