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.
If the unit is plugged in and power is connected to the spa, then the fuse (for the ozone generator) should be checked.
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 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.
Acts of nature, and damage caused by animals, rodents, and insects are considered abuses and are not covered under this warranty.
*Operation of the spa does not mean “use” of the spa! Watkins Manufacturing Corporation does not recommend using the spa if the water
temperature is above or below the spa’s control panel temperature range.
DISCLAIMERS
Watkins Manufacturing Corporation shall not be liable for loss of use of the Hot Spring spa or other incidental, consequential, special, indirect, or
punitive costs, expenses or damages, which may include but are not limited to the removal of a permanent deck or other custom fixture or the
necessity for crane removal. Any implied warranty shall have a duration equal to the duration of the applicable limited warranty stated above.
Some states do not allow limitations on how long an implied warranty lasts. Under no circumstances shall Watkins Manufacturing Corporation or
any of its representatives be held liable for injury to any person or damage to any property, however arising.
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitations may not apply to you.
