Filter Cleaning - Cal Spas LTR20121002 Owner's Manual

Shocking the Water
In addition to using a chemical sanitizer, you will periodically need to shock the water. Shocking the water
helps remove burned-out chemicals, bacteria, and other organic material from your spa's water and im-
proves your sanitizer's effectiveness.
Do not use chlorinating shock, which will damage your spa's jets and pump seals. Only use an oxidizer shock.
It can be used with either chlorine or bromine sanitizers.
Add one ounce of oxidizer shock once a week, after heavy bather loads, or if the water has a strong odor.
Spa must be running with all of the jets on high for 30 minutes with the cover open. If necessary, repeat
oxidizer shock in 30 minute intervals.
Chemical Safety
Read and follow all printed instructions listed on bottles, packages . Failure to follow
chemical directions may result in serious injury, sickness, or even death .
Do not exceed chemical dosages as recommended
in the Clear Water Plan or on chemical bottles and
packages.
Never change chemical brands or types without com-
pletely draining, flushing and thoroughly cleaning the
spa and cover first.
Never mix chemicals together.
Do not allow chemicals to come in contact with skin,
eyes or clothing. Remove and wash clothing that

Filter Cleaning

The filter is the part of your spa that removes the
debris from the water and needs to be cleaned on a
regular basis to maximize your spa's filtering perfor-
mance and heating efficiency.
In addition to spraying off the filter weekly to remove
surface debris, your filter should be deep cleaned
periodically to dissolve scale and particles that get
lodged deep within the filter fibers and impede the
filtration process. Even if the filter looks clean, scale
and particles can clog the fibers and prevent water
from flowing through the filter resulting in the most
common spa problem—no heat, caused by a dirty
filter.
We recommend you clean your filter once a month
and replace it once a year or as necessary.
1. Remove the filter by turning it counterclockwise,
unscrewing the bottom threads, then pulling it
up and out.

may have been exposed to chemical contact prior to
wearing them again.
Inhaling or ingesting chemicals will cause serious in-
jury, sickness, or even death.
Chemicals must be stored completely out of the
reach of children in an area that is well vented, cool,
and dry. Failure to provide a proper area for chemical
storage may result in serious injury, sickness, fire ex-
plosion and even death. Do not store your chemicals
inside the equipment area of your spa.
2. Place the dirty filter into a bucket of water deep
enough to cover the filter. Add 8 oz of liquid filter
cleaner to the bucket of water.
Note: It is a good idea to keep a spare filter to
use in the spa while the dirty filter is being deep
cleaned. This way, you can rotate the filters and
both will last longer.
3. Twist off the tablet tube and set it aside
4. Soak the filter for a minimum of 24 hours.
5. Spray the filter with a water hose. Spray each
pleat carefully.
6. Put fresh bromine in the tablet tube (if you use
it as a sanitizer) and twist it back on top of the
filter.
7. Reinstall the filter. Do not overtighten.
