It is important to note that the No-Fault
causes of heater high limit tripping are discussed in the previous section.
If the hot tub is not heating, the red and green lights are blinking, but the pump and light are operating, then the pressure switch may be open.
Opening of the pressure switch is normally a result of one or a combination of these problems: 1) a clogged filter cartridge, 2) blockage within the
system plumbing, 3) power was not disconnected to the hot tub before it was drained, or 4) an air lock in the plumbing lines. Once the problem
has been identified and corrected the pressure switch will close which will energize the heater.
SILENT FLO 5000
PUMP THERMAL CUT-OFF
The Silent Flo circulation pump is a dedicated, water cooled, energy efficient, quiet pump that provides continuous filtration for the hot tub. Since
the Silent Flo circulation pump is water cooled, it is equipped with a thermal cut-off to prevent the pump from being damaged by running hot
when water is not present.
Reset the circulation pump's thermal cut-off by disconnecting power to the hot tub and allowing the pump to cool.
Tripping of the thermal cut-off is normally the result of one or a combination of these problems: 1) clogged filter cartridge(s), 2) blockage within the
system plumbing, 3) power was not disconnected to the hot tub before it was drained, or 4) an air lock in the plumbing lines. Once the problem
has been identified and corrected the pump thermal cut-off will be able to be reset which will allow it to operate normally.
FRESHWATER
The FreshWater III ozone system is practically maintenance-free because it is located within the hot tub's equipment compartment.
WARNING: Contact your Limelight
systems should only be serviced by a qualified technician.
WARRANTY NOTE: Cleaning of the ozone injector is not covered under the warranty. Refer to the Ozone section of this manual for instructions
on cleaning the ozone injector.
MISCELLANEOUS SERVICE INFORMATION
The control and high-limit thermostats are equipped with electronic sensors that are connected to the hot tub's plumbing. Never cut or kink the
wires that connect the sensors to the thermostats within the control box.
The jet pump is equipped with a thermal overload cutoff switch that is designed to protect the pump from overheating. If the pump shuts itself off
in a new hot tub, it is usually the result of one or a combination of the following factors:
• Thermal overload: Although mass-produced, not all thermal overload cutoffs are exactly the same. Some are more sensitive than others
and will shut the pump off at lower temperatures.
• High temperature: All Limelight hot tubs models are equipped with a jet pump shroud that vents the heat generated by the pump motor to
the outside of the equipment compartment, and back into the hot tub water. if the vent is blocked by masonary, grass or debris,
overheating of the jet pump may occur. Once the pump motor has cooled sufficiently and any blockage has been removed from the vent
opening, the jet pump can be restarted.
• Improper wiring: If the hot tub is connected incorrectly, and/or the house wiring is undersized, the pump may starve for voltage and
therefore may draw more amperage and generate excessive heat.
• If the pump is shutting down due to excessive heat, make sure the equipment compartment has adequate ventilation. The air screens at
the bottom must not be blocked. Should your jet pump continue to shut off after short periods of use, contact a qualified service technician.
ACTS INVALIDATING WARRANTY
The limited warranty is void if the Limelight hot tub has been subjected to alteration, misuse, or abuse, or if any repairs on the hot tub are
attempted by anyone other than an authorized representative of Watkins Manufacturing Corporation. Alteration is defined as any component or
plumbing change, electrical conversion, or the addition of any non-approved sanitation or water purification device, or heating system which
contributes to a component failure, unit failure or unsafe operating condition. Misuse and abuse shall include any operation of the hot tub other
than in accordance with Watkins Manufacturing Corporation printed instructions, or use of the hot tub in an application for which it is not
designed; specifically: use of the hot tub in a non-residential application; damage caused by operation* of the hot tub at water temperatures
outside the range of 35°F and 120 °F; damage caused by a dirty, clogged or calcified filter cartridge; damage to the hot tub surface caused by the
use of tri-chloro chlorine, BCDMH, chemical tablets in a floater, acid, or any other hot tub chemicals or hot tub surface cleaners which are not
recommended by Watkins Manufacturing Corporation; damage caused by allowing undissolved hot tub sanitizing chemicals to lie on the hot tub
surface (no hot tub surface material can withstand this kind of abuse); damage to components or hot tub surface caused by improper water
chemistry maintenance; and damage to the hot tub surface caused by leaving the hot tub uncovered while empty of water and in direct exposure
to sunlight (this may cause solar heating distress in warm weather regions). These are considered abuses and may invalidate this warranty.
Acts of nature, and damage caused by animals, rodents, and insects are considered abuses and are not covered under this warranty.
*Operation of the hot tub does not mean "use" of the hot tub! Watkins Manufacturing Corporation does not recommend using the hot tub if the
water temperature is above or below the hot tub's control panel temperature range.
