WATER QUALITY AND MAINTENANCE

spa water.
• Monarch CD Ozone Generator - The Monarch high output ozone system is the only ozone purification system approved for installation in your Caldera®Spa.
The Monarch ozone system utilizes Corona Discharge (CD) technology to produce a higher concentration of ozone than is produced by competing chip style
CD or ultraviolet light ozone systems.
• Monarch Non-Chlorine Oxidizer Monopersulfate (MPS) is an oxidizing chemical used to prevent the buildup of contaminants, maximize sanitizer efficiency,
minimize combined chlorine, and improve water clarity.
• Sodium Dichlor (chlorine) is the only recommended sanitizer that will work in conjunction with all of the other products in this system.
It is important to follow the recommended application and maintenance programs outlined for each product’s use.
If the spa is being used over an extended period or time, such as a whole afternoon or evening, additional sanitizer will be needed.
A weekly “shock treatment” is required.
The shock treatment quickly destroys any remaining contaminants while revitalizing the silver cartridge, allowing the silver ions to continue to be released into the
water. Without this weekly shock treatment, the silver cartridge may stop releasing silver ions into the water.
To weekly “shock treat” your spa you may use either MPS or sodium dichlor. It will require much less sodium dichlor to administer the shock treatment than MPS (1
teaspoon of sodium dichlor has oxidizing capabilities comparable to 2 tablespoons of MPS). Sodium dichlor may be a more appropriate weekly shock for those users
that experience heavy bather load conditions.
IMPORTANT NOTE: MPS is an oxidizer, not a sanitizer.
MONARCH SILVER CARTRIDGE INSTALLATION INSTRUCTIONSWhen replacing the silver cartridge (every four months), it is highly recommended that the spa be drained and refilled at the same time. After refilling the spa with water,
balance the Total Alkalinity (TA), Calcium Hardness (CH) and pH to the recommended levels. Shock the spa by adding sodium dichlor.
1. Release the cover locks and fold back the cover.
2. Remove the filter lid.
3. Make sure the filter compartment is clear of any floating objects.
4. Drain the spa using the recommended procedures found in this Owner’s Manual (pg 24).
PLEASE NOTE: The Monarch®silver cartridge CANNOT be used with bromine, sodium bromide or biguanides. If you have previously used any of these products in the
spa, it is recommended that the shell and filter compartment be cleaned. It is also recommended that the filters be cleaned with a filter cleaner before the Monarch
cartridge is installed. (Review the shell and filter cleaning procedures.)
5. Push down slightly and turn filter basket counter-clockwise to unlock, then pull out the basket and weir.
6. Grab handle and lift filter straight up and out.
IMPORTANT NOTICE: If you have used the spa prior to this installation, clean the filter to ensure the Monarch silver cartridge performs optimally. It is
recommended to clean the filter each time you replace the Monarch cartridge.
7. Insert the stem of the Monarch silver cartridge, into the top of the filter standpipe at the bottom of the filter canister.
(See pg. 22)
8. Carefully replace the filter, the filter basket and weir.
