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
CALDERA
spa models are equipped with a jet pump that generates heat inside the equipment compartment from the pump motor. Your
spa has a vent to the outside of the equipment compartment preventing the overheating of the pump motor. 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 buildup 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
CALDERA
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
1.5°C (35°F) and 49°C (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, misuse of 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.
*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
CALDERA
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 countries do not allow the exclusion or limitation of incidental or consequential damages, so the above limitations may not apply to you.
