7.  Close the spa cover and fasten the cover tie downs. Cover the spa cover with 

two pieces of plywood to evenly distribute the weight of snow and ice. Secure a 

plastic sheet, or tarp, over the spa cover and plywood.

8.  Replace the equipment access door, if removed.

OPENING INSTRUCTIONS:

1.  Remove plywood and plastic sheet. Open the spa cover by 

unfastening the cover tie downs.

2.  Follow the Start-up and Refill Procedures in the Operating 

Instructions section of the Owner’s Manual.  Do not install filters to 

prevent them from exposure to the anti-freeze.

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

three teaspoons of chlorine (sodium dichlor) per 250 gallons 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 and Refill Procedures in the Operating Instructions 

section of the Owner’s Manual.

IMPORTANT:

 Always keep spa covered when not in use, whether it is 

empty or full.

FILTER SYSTEM

The filter lid on the spa is NOT designed to support heavy weight loads 

and should not be used as a seat. In extreme cases, the lid could crack 

and break. This occurrence is considered abuse and is not covered under 

the warranty.

CALDERA

 spas are equipped with one filter cartridge, sized to meet the 

needs of the jet pump system. 
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: 

To reduce the risk of injury to persons using the spa, DO 

NOT remove the suction fittings (filter standpipes) located in the filter 

compartment and do not sit on the filter lid, in extreme cases the lid could 

crack and break. This occurrence is considered abuse and is not covered 

under warranty.

SECONDARY SUCTION SCREEN

Located in the foot well of your spa are three secondary suction screens. 

The screen is used as a filter to prevent dirt from circulating through the 

system.

WARNING: 

Do not use the spa with the suction screens removed.
