MAINTENANCE
3 days a week
Check water level. Make certain water level is 1 inch above the
highest jet.
Check and adjust Chlorine level to 1.0 to 3.0 ppm if Chlorine is
used as sanitizer. If Bromine is used, check weekly.
Once a week
Test the spa water using test strips or test kit.
Adjust pH and total alkalinity - refer to pH and total alkalinity on
label of SPA UP and SPA DOWN.
Check and adjust Bromine level to 1.0 to 3.0 ppm if Bromine is
used as sanitizer. If Chlorine is used, check three times a week.
Add 1 ounce of SPA DEFENDER per 400 gallons of water to
prevent calcium build up.
Shock treat with 2 ounces of RENEW, a non-chlorine shock.
Check and clean the skimmer basket and weir to insure proper
filter flow, remove leaves, foreign matter and debris.
Check spa cover. Make certain cover is positioned properly and
tie-down straps are fastened/locked. Be sure water and snow are
swept off or kept from accumulating or puddling on the cover.
Four to six weeks
Inspect and clean the spa filter cartridge. It is very important to
maintain your spa filter cartridge and keep it clean and free of particles
which can restrict water flow. If the filter is not cleaned on a regular
basis, the filter may clog and restrict water flow, which causes improp-
er filtration and poor jet performance. See “ FILTER CARTRIDGE
REMOVAL AND CLEANING INSTRUCTIONS” on page 10.
Two months (heavy usage)
Drain your spa. Follow the procedures outlined in “DRAINING
Five months (light usage)
YOUR SPA” on page 10. Clean the spa with “Spa Multi-Purpose
Cleaner” and then polish with a silicone sealant polish. When refilling
your spa be sure to follow the “START-UP” instructions on page 4.
Six months
Clean and seal your spa skirt. The spa skirt is coated with a
tinted stain for protection and to enhance the beauty of the natural
redwood. Like all wood products, prolonged exposure to the
weather and climate conditions will cause the redwood to discolor
or fade. To maintain the rich finish, apply a good quality tinted or
clear stain every six months.
Note: The stain used by Caldera is available from your Caldera
dealer.
