The Hot Spring Silent Flo 5000 circulation pump is a dedicated, water cooled, energy efficient, quiet pump that provides continuous
filtration for the spa. Since the Silent Flo 5000 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
The FreshWater III ozone system is practically maintenance-free because it is located within the spa's equipment compartment. If
bubbles are appearing at the spa's heater return but the smell of ozone is not noticeable (the water may also appear not as clear as
usual) then the operation of the ozone generator should be checked. Carefully open the equipment compartment door (remember to use
care, as power is still connected to the spa) and verify that the CD tube and its transformer are energized (a slight buzz will be emitted
from the ozone generator housing). If a slight buzz or hum is not audible, verify that the generator is completely plugged into the spa's
control box.
WARNINg: Contact your Hot Spring dealer if your spa requires troubleshooting beyond the scope of this manual. Freshwater
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
ozone injector cleaning instructions.

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 an older spa, it could indicate failure of the pump motor bearings. 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 spa 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 masonry, 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.
• Friction: Sometimes the moving parts of a new pump are tight enough to cause heat build-up due to friction. After a normal break-in period,
the pump will run cooler.
• Improper wiring: If the spa is connected with an extension cord, 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 gap 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 improperly installed, 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
shall include 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 component or unit failure or unsafe operating system. 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 caused by a dirty, clogged or calcified filter
cartridge; damage to the spa surface caused by the use of tri-chloro chlorine, BCDMH, chemical tablets in a floater, acid, or any other
spa chemicals or spa surface cleaners which are not recommended by Watkins Manufacturing Corporation; damage caused by allowing
undissolved spa sanitizing chemicals to lie on the spa surface (no spa surface material can withstand this kind of abuse); damage to
components or spa surface caused by improper water chemistry maintenance; and damage to the spa surface caused by leaving the
spa 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.
