3.  As part of this process, superchlorinate the spa water by adding 

three teaspoons of chlorine (sodium dichlor) per 250 gallons (950 

liters) of spa water into the filter compartment.  This is twice the 

normal amount of chlorine needed for superclorination. This extra 

amount of chlorine is needed to destroy the anti-freeze.

NOTE: 

A defoamer may be needed to decrease the amount of  

foam caused by the anti-freeze.

4.  Drain your spa to ensure removal of anti-freeze.  Do not drain water 

on grass or plants due to excessive chlorine level.

5.  After the spa has completely drained, re-install your filter and 

follow the Start-up Procedures in the Getting Started section of the 

Owner’s Manual.

IMPORTANT:

 Always keep spa covered when not in use, whether it 

is empty or full.

CARE OF THE SPA PILLOWS 

The 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. 

TO REMOVE AND REPLACE THE SPA 

PILLOWS:

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.

CARE OF THE EXTERIOR

SPA SHELL

Your 

CALDERA

 spa has an acrylic shell. Stains and dirt generally will not 

adhere to your spa’s surface. A soft rag or a nylon scrubber should easily 

remove most dirt. Most household chemicals are harmful to your spa’s 

shell (see below for detailed information on cleaning agents). Always 

rinse off any spa shell cleaning agent with fresh water.

IMPORTANT:

1.  The following products are the ONLY approved cleaning agents 

for your 

CALDERA

 spa shell: plain water, 

CALDERA

 Spa Shine, 

Brillianize

®

 or Soft Scrub

®

. The use of alcohol or any other 

household cleaner other than those listed to clean the spa shell 

surface is NOT recommended. DO NOT use any cleaning products 

containing abrasives or solvents since they may damage the shell 

surface, specifically: Simple Green

®

, Windex

®

 or Spa Mitt. NEVER 

USE HARSH CHEMICALS! Damage to the shell by use of harsh 

chemicals is not covered under the warranty. Always rinse off any 

spa shell cleaning agent with fresh water.

2.  Iron and copper in the water can stain the spa shell if allowed to go 

unchecked. Ask your 

CALDERA

 dealer about a Stain and Scale 

Inhibitor to use if your spa has a high concentration of dissolved 

minerals. (

WATKINS WELLNESS

 recommends Stain & Scale 

Defense.)

3.  Keep all cleaners out of the reach of children and use care when 

applying.

ECOTECH 

®

PLUS SPA CABINET 

All Utopia spas use the exclusive all-climate 

ECOTECH PLUS

 Cabinet 

designed for years of performance. The unique, ribbed pattern design is 

enhanced by the rich cabinet colors that give the appearance of high-end 

furniture, without looking like real wood and, because of the durability 

of the spa cabinet material, it comes with a five year warranty against 

cracking, or rotting.

CARE OF THE SPA COVER

WARNING:

 The cover is a manual safety cover that meets or 

exceeds all prevailing requirements of ASTM Standards for spa safety 

covers when installed and used correctly as of the date of manufacture. 

Non-secured or improperly secured covers are a hazard. Open the cover 

to its fully open position before use.

VINYL COVER

The vinyl spa cover is an attractive, durable foam insulation product. 

Monthly cleaning and conditioning are recommended to maintain its 

beauty.

TO CLEAN AND CONDITION THE VINYL 

COVER:

SERVICE NOTE:

 To remove tree sap, use cigarette lighter fluid (not 

charcoal lighter fluid). Use sparingly, and rinse with a saddle soap solution 

immediately afterwards, then wipe dry.

IMPORTANT REMINDERS:

•  DO

 remove snow buildup to avoid breakage of the foam core from 

the additional weight of the snow.

•  DO

 lock cover lock straps to secure the cover when the spa is not 

in use.

•  DO NOT

 drag or lift the spa cover using either the flaps or the cover 

lock straps.

•  DO NOT

 walk, stand, or sit on the cover.

•  DO NOT

 place any metal or heat transferring object on the cover 

or place any type of plastic tarp or drop cloth over the cover as 

this may result in a melted foam core, which would not be covered 

under the warranty.

•  DO NOT

 use any lifting mechanisms, chemicals or cleaners except 

those recommended by 

WATKINS WELLNESS

 or its Authorized 

Sales and Service Dealer.

•  It’s important to have clean water. Water maintenance is one of 

the least understood, yet most important areas of spa ownership. 

Your dealer can guide you through the process of achieving and 

maintaining perfect water in your spa, given your local conditions. 

Your program will depend on your water’s mineral content, how 

often you use your spa, and how many people use it.
