Changing/Cleaning Filters
We strongly recommend that you clean the lter every one to three weeks depending on how
often your spa is used. Just because a lter is dirty does not mean it needs to be replaced. Fil-
ters that are cleaned regularly can last up to 12 months. To determine whether your lter needs
replacing look within the pleats of the lter inspecting for any build up of grime and dirt particles
after cleaning. If dirt particles remain the lter should be replaced. Filters are not designed to last
more than 12 months. We recommend using ThermoSpas Filter Clean to clean the lter(s) in
your spa.
Note: Some ThermoSpas spas use two or more lters.
DANGER: RISK OF SEVERE INJURY OR DROWNING BY ENTRAPMENT!
• Keep hair, loose articles of clothing or hanging jewelry away from suction ttings, rotating jets
or other moving components to avoid entrapment that could lead to drowning or severe injury.
• Never use the spa unless all suction guards, lter, lter lid, or skimmer assembly are installed
to prevent body and/or hair entrapment.
• Never operate or use the spa if the lter, lter lid, or skimmer assembly are broken or any part
of the skimmer assembly is missing. Please contact your dealer or nearest service center for
service.
• The suction ttings and suction covers in this spa are sized to match the specic water ow
created by the pump(s). If it is necessary to replace the suction ttings, suction covers or
pump(s), be sure that the ow rates are compatible and are in compliance with the VGB
Safety Act.
• Never replace a suction tting or suction cover with one rated less than the ow rate marked
on the original suction tting. Using improper suction ttings or suction covers can create a
body or hair suction entrapment hazard that may lead to drowning or severe injury.
• Owners must alert all spa users to the potential risk of Hair, Limb, Body, Evisceration
(disembowelment) and Mechanical Entrapment.
Cleaning The Filter
DANGER: TURN POWER TO SPA OFF! TO DECREASE RISK OF DEATH, DROWNING, OR EN-
TRAPMENT, NEVER OPERATE SPA WHEN FILTER IS NOT PROPERLY INSTALLED OR IF SKIM-
MER ASSEMBLY IS DAMAGED OR ALTERED!
During ltration and automatic cycles, water ows through the spa skimmer and into the lter
cartridge(s) to trap suspended particles and oils on their surface pleats. To ensure optimum
performance, it is necessary to remove and clean the lter cartridge(s) once a month or sooner
depending on spa use and water quality.
The skimmer/lter for the Designer Series can vary. To follow are the four distinct skimmer hous-
ing and the cleaning procedure for each.
