Oxidizer: The use of an oxidizing chemical is to prevent the buildup of contaminants, maximize sanitizer efficiency, minimize combined chlorine
and improve water clarity.
Ozone: ozone is a powerful oxidizing agent which is produced in nature and artificially by man. ozone forms no byproducts of chloramines (ozone
actually oxidizes chloramines) and will not alter the water's pH.
Pathogen: A microorganism such as bacterium that cause disease.
pH: The measure of the spa water's acidity and alkalinity. The recommended pH for the spa water is 7.2 to 7.6. Below 7.0 (considered neutral), the
spa water is too acidic and can damage the heating system. Above 7.8, the water is too alkaline and can result in cloudy water, and scale formation
on the shell and heater.
ppm: The abbreviation of "parts per million", the standard measurement of chemical concentration in water. Identical to mg/l (milligrams per liter).
Reagent: A chemical material in liquid, powder, or tablet form for use in chemical testing.
Sanitizer: sanitizers are added and maintained at recommended residuals to protect bathers against pathogenic organisms which can cause
disease and infection in spa water.
Scale: Rough calcium-bearing deposits that can coat spa surfaces, heaters, plumbing lines, and clog filters. Generally, scaling is caused by mineral
content combined with high pH. Additionally, scale forms more readily at higher water temperatures.
Super-Chlorination: Also known as "shock treatment." super-chlorination is a process of adding significant doses of a quick dissolving sanitizer
("dichlor" is recommended) to oxidize non-filterable organic waste and to remove chloramines and bromamines.
Total alkalinity: The amount of bicarbonates, carbonates, and hydroxides present in spa water. Proper total alkalinity is important for pH control.
If the TA is too high, the pH is difficult to adjust. If the TA is too low, the pH will be difficult to hold at the proper level. The desired range of TA in spa
water is 40 to 120 ppm.
SERvIcE INFORMATION
®
your Limelight
spa has been designed to provide years of trouble-free use. As with any appliance, problems may occasionally occur that require
the expertise of a qualified service person. Though such simple repairs as resetting a GFcI switch or breaker, resetting a high limit thermostat
or replacing a light bulb may not require a service call, they may indicate that a more serious condition exists. These conditions may require an
experienced service person. Before calling for service, please refer to the Troubleshooting Guide.
NOTE: Always retain your original sales receipt for future reference.

If your spa fails to operate at any time, first check the power supply to the spa.
check each of the GFcI breakers in the subpanel. If a GFcI has tripped, reset it. If it will not reset, this may be an indication of a ground fault (short
circuit) within the electrical components. contact an Authorized service Technician for a complete diagnosis.
If upon checking the GFCI's you find that they have not tripped, check the house breaker panel and ensure that the main breaker for the electrical
circuit supplying the spa has not tripped. If it has, this is an indication that the circuit was either overloaded or a ground fault exists between the
breaker panel and the spa receptacle or subpanel. contact a qualified electrician.
If upon checking the main house breaker and spa GFCI's you find no failures, check the high limit thermostat. To check it, simply turn off power to
the spa for 30 seconds. This will automatically reset the high limit thermostat if it has tripped. If the spa energizes once you turn the power back on,
this indicates reduced water flow through the heating system. Tripping of the high limit thermostat is normally a result of one or a combination of
these problems. 1) clogged filter cartridges, 2) blockage within the system plumbing, 3) a non-functioning heater circulation pump, 4) power was not
disconnected from the spa before it was drained, 5) an air lock in the plumbing lines. (The Power Indicator on the front of the spa's control panel will
also be blinking if the high limit thermostat circuit has tripped.)
If the spa does not function after tripping and resetting the GFCI's or resetting the high limit thermostat, then the problem should be referred to a
®
qualified service technician. Refer to the No-fault
Heater section if the spa operates but does not heat, or refer to the Troubleshooting Guide for
additional service information.
