Caldera Highland Series User Manual

At least once a week, check and clean the skimmer basket and weir to ensure proper filter flow. Remove leaves, foreign matter, and debris. It is very important to keep
your spa filter cartridge clean and free of particles to ensure proper water flow. A clean filter permits the hydrotherapy system to function properly and also allows more
efficient filter cycles. Depending on how frequently your spa is used, we recommend cleaning the spa filter cartridge every four weeks. If this is not done, the filter may
clog and restrict water flow, which causes improper filtration and poor jet performance.

WARNING: The frequency and duration of use, and the number of occupants all contribute to determining the appropriate time between filter cleanings. More use

means that more frequent filter cleanings will be required.

Turn the power to the spa OFF, then proceed as follows:

1.  Push down slightly and turn filter basket counterclockwise 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.  Install filter then replace basket and weir by inserting and rotating clockwise to lock into position.

Spa pillows will provide years of comfort if treated with care. They have been positioned above the water level to minimize the bleaching effects of chlorinated water and
other spa water chemicals. To extend their life, whenever the spa shell is being cleaned, the spa pillows should be removed and cleaned. Body oils can be removed with
a mild soap and water solution. ALWAYS rinse off the spa pillows thoroughly to remove any soap residue. If the spa is not going to be used for a long period of time
(that is during a vacation or if the spa is winterized), or when the spa water is being super-chlorinated, the spa pillows should be removed until the next use of the spa. 

1.  Carefully lift one end of the pillow away from the spa shell.

2.  Continue lifting one end until all pillow retainers are released from the pillow.

IMPORTANT: Just pulling the pillow straight up and out of the shell recess will eventually damage the pillow. This abuse is not covered under warranty.

3.  To reinstall the spa pillow, carefully bend the pillow slightly to allow one of the pillow retainers to slip into the recess in the back of the pillow.

4.  Keeping the pillow slightly bent, slide the other pillow retainer into the recess in the back of the pillow.

5.  After all the pillow retainers are in place, press the pillow down into the recess in the spa shell.
