NO-FAUlT
®
HEATER ANd INTEgRATEd PRESSURE
SWITCH
Watkins Manufacturing Corporation unconditionally warrants the No-Fault heater against any failure that would require replacement. This warranty’s
duration is equal to the time period identified in the component Warranty. This warranty defines unconditional as warranty coverage without
exception provided that the component has failed to operate properly within the spa’s system. This means that conditions that would normally
invalidate the limited warranty, such as water chemistry damage, do not apply to the No-Fault heater.
It is important to note that the No-Fault heater is protected by both the heater high limit thermostat circuit and the integrated pressure switch. The
causes of heater high limit tripping are discussed in the previous section.
If the spa 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 spa 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.

CIRCUlATION PUMP ANd
CIRCUlATION PUMP THERMAl CUT-OFF
The silent Flo circulation pump is a dedicated, water cooled, energy efficient, quiet pump that provides continuous filtration for the spa. 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 spa 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 spa 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

III HIgH OUTPUT OZONE SYSTEM (OPTIONAl)
The FreshWater III ozone system is practically maintenance-free because it is located within the spa’s equipment compartment.
WaRNING:
contact your
Hot Spring
®
dealer if your spa requires troubleshooting beyond the scope of this manual. Freshwater III ozone
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 spa’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 spa, 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
Hot Spring
spas 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 spa 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 spa 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
Hot Spring
spa has been subjected to alteration, misuse, or abuse, or if any repairs on the spa 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 spa other than in accordance
with Watkins Manufacturing Corporation printed instructions, or use of the spa in an application for which it is not designed; specifically: use of the
spa in a non-residential application; damage caused by operation* of the spa at water temperatures outside the range of 35°F and 120 °F; damage
