FILTER MAINTENANCE
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, poor jet performance and possibly freezing.
IMPORTANT: 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.
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 out the basket and weir.
2. Carefully pull up the filter cartridge and bring it out of the spa.
3. Always clean the filter using a filter degreaser to remove mineral and oil build-up. Simply soak the filter in the degreaser (according to the package directions), then
place the filter on a clean surface and spray until clean using a garden hose. It may be necessary to rotate the filter while spraying to remove any debris lodged
between the filter pleats.
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 by tripping both GFCI breakers located in the subpanel.
2. Unscrew the cap ring to remove the diverter valve’s handle as cap ring comes upward.
3. Remove the valve body by pulling it upward.
4. Wipe the valve body and the interior walls of the valve clean.
5. Lubricate the o-rings with a waterproof lubricant available from your Caldera dealer.
6. Reassemble the valve and turn power to the spa on.
