CalderaSpas PLT1S1001, Owner'S Manual

NOTe: refer to the Start-Up instructions on page 7 or your FrOG owner's manual for start-up and operation instructions. The owner's manual can be  

 found with your FrOG starter kit.

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.

NOTe: The FrOG Mineral Cartridge is not approved for use in Canada.

NOTe: 

For Canada, if you are only using the bromine cartridge, your bromine levels should be between 3.0 - 5.0 ppm.

  CARTRIdgE REPlACEMENT INSTRUCTIONS

The 

FrOG

 bromine cartridge should be replaced every 2-4 weeks, depending on User Load.  The 

FrOG

 mineral cartridge should be replaced every 4 months.  When 

replacing the mineral cartridge, 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 

MONarCH

 MPS Plus non-chlorine shock shock or sodium dichlor 

(chlorine), then replace the cartridges.
To replace 

FrOG

cartridges, follow these steps:

1.  Turn off power to the spa

2.  Unscrew 

FrOG

 cap on top edge of spa

3.  Turn handle counter-clockwise

4.  Lift cartridge holder up and out of spa

5.  Remove and discard old cartridges

6.  Turn top cap of new Mineral cartridge to setting #6

7.  Turn top cap of new Bromine cartridge to setting #7

8.  Snap bromine cartridge into the bottom of holder and snap mineral cartridge into the top 

IMPOrTaNT:

 It is important that the bromine cartridge is on the bottom; otherwise, the bromine cartridge could dispense prematurely.

9.  Reinstall cartridge holder into spa, push down, and twist clockwise.

10.  Replace 

FrOG

 cap

11.  Reconnect power to the spa

IMPOrTaNT NOTe:

Adjust bromine cartridge setting down by one setting each day until a residual of 1.0 - 2.0 ppm level of bromine is established

WarNING:

High sanitizer levels can cause discomfort to the user’s eyes, lungs and skin. Always allow the sanitizer level to fall to the recommended range before 

using the spa.

 SANITIzER  ROUTINE

During the first month of ownership, measure the sanitizer residual daily in order to establish the correct setting on cartridges for User Load and Usage Time versus 

Sanitizer Needed. 

• 

USer lOad

 is the spa is the number of times anyone enters the spa. 

• 

USaGe TIMe

 is simply the amount of time a user spends in the spa. 

• 

Sanitizer Needed

 is the amount needed to accommodate the number of users and their combined usage time.

For example, two spa users who regularly use the spa once an evening for twenty minutes create a specific and somewhat consistent demand on the sanitizer. During 

the first month of ownership, these two users can determine exactly how much sanitizer to use in order to maintain the proper residual. If, at any time, the user load and/

or usage pattern changes dramatically (i.e. invited guests), the amount and frequency of sanitizer required increases dramatically. The greater the usage time, or the 

bather load, the faster the residual value is diminished.

bROMINE

A.   Sanitizing chemicals, such as bromine, are oxidants that kill bacteria and viruses in the water.  If you are using the 

FrOG

 system, the recommended bromine level 

for your spa water is 1.0 - 2.0 ppm.  If you are not using the 

FrOG

 system, your bromine level should be between 3.0 - 5.0 ppm. 

NOTe:

For Canada, if you are only 

using the bromine cartridge, your bromine levels should be between 3.0 - 5.0 ppm.

B.  When not using the 

FrOG

 system Watkins Manufacturing Corporation recommends the use of granulated bromine for sanitizing the water. Granulated bromine is 

preferred because it is totally soluble, dissolves quickly and is nearly pH neutral.

C.  Maintaining the proper level of bromine during use is extremely important.
D.  If the bromine level is too low, bacteria and viruses can grow rapidly in the warm water.
E.  If the bromine level is too high, the water can cause discomfort to the user’s eyes, lungs and skin. 

Simply allow some time to pass in order for the bromine to dissipate.

F.  When the bromine level is within the recommended range, the spa is ready to be enjoyed.

dO’S ANd dON’TS

• 

dO check your bromine chemical level prior to each use.

• 

dO change the FrOG mineral cartridge every 4 months.

• 

dO test Total alkalinity and pH weekly.

• 

do use MONarCH chlorine.

• 

dO use MONarCH MPS or MPS+ non-chlorine (monpersulfate) oxidizer for spa only.

• 

dO store all chemicals in a tightly sealed contriner in a cool, dry place.

• 

dON'T use sodium bromide or biguanides. These are an active sanitizer and will combine with the silver ions to inactivate them.
