FILTER CARTRIDGE REMOVAL AND
CLEANING INSTRUCTIONS
Turn the power to the spa off, then proceed as follows:
1. Push down slightly and turn filter basket counter-clockwise to unlock, then
pull the basket and weir out.
2. Carefully pull up the filter cartridge and bring it out of the spa.
3. Rinse cartridge using a garden hose. Rotate and separate filter pleats while
spraying water to remove all debris possible. Let the filter dry and then look
for calcium deposits (scaling) or an oil film. If you find these, you will need to
deep clean your filter cartridge with a “spa filter cleaning” solution to break
down and remove mineral deposits and oils.
4. To return basket and weir, insert and rotate clockwise to lock into position.
Then, turn spa’s power back on.
NOTE:
Replacement filter cartridges are available from your Caldera dealer. Refer
to the back of this manual to determine the appropriate size for your spa.

DIVERTER VALVE MAINTENANCE
If your spa’s diverter valves become difficult to turn, it is likely that sand or grit has
become lodged inside the valve body. It is very important that this debris is removed as
soon as possible to avoid damage to the valve. To accomplish this, follow this
procedure:
1. Turn off power to the spa.
2. Remove the diverter valve’s handle by pulling upward while rocking it back and
forth.
3. Unscrew the cap ring.
4. Remove the valve body by pulling it upward.
5. Wipe the valve body and the interior walls of the valve clean.
6. Lubricate the valve body with a waterproof lubricant available from your Caldera
dealer.
7. Reassemble the valve and turn on power to the spa.
