Additional chemicals can be purchased at a pool and
spa supply store.
CAUTION: The chemicals used to maintain the pH
balance of the water and to sanitize the water can
be dangerous. Always follow these basic guide-
lines when handling the chemicals:
1. Always read and follow the directions on the
label, unless directed otherwise.
2. Never mix different chemicals.
3. Do not exceed the recommended amounts of
chemicals—follow the directions on the label
closely.
4. Keep all chemicals out of the reach of children
and pets.
5. Keep all containers closed tightly when not in
use.
6. Never add water to the chemicals—always add
the chemicals to the water as directed.
7. Always store chemicals in a cool, dry place.
MAINTAINING THE PROPER PH BALANCE
The pH factor is a measure of relative acidity or alka-
linity in the water. It is measured on a scale of 1 to 14.
Pure water has a value of 7, which is neutral. Any
value above 7 is alkaline, and any value below 7 is
acidic. You should maintain a slightly alkaline pH
level, between 7.2 and 7.8, in the hydrotherapy spa.
Severe problems can occur when the pH balance is
not maintained within this range. If the pH level
exceeds 7.8, dissolved minerals can build-up and clog
the plumbing in the spa jet unit. If the pH level falls
below 7.2, the acid level in the water will begin to cor-
rode the metal parts in the spa jet unit. Also, the sani-
tation agents in the water will not be effective if the pH
level is not properly maintained. Damage caused by
improper pH levels is not covered under the warranty.
To maintain the proper pH level, you should test the
pH of the water regularly, using the included pH test
kit. The pH reading should be between 7.2 and 7.8. If
the level is too low, add a pH increaser (usually soda
ash). If the level is too high, add a pH reducer (usually
sodium bisulfate). Test the water again after five min-
utes. See the instructions with your pH test kit for addi-
tional information about testing and adjusting the pH.
ATTACHING AND REMOVING THE ACCESS COVER
To locate the access cover, refer to the drawing on
page 6. Turn off the power to the spa. To remove the
access cover, first remove the four access cover
screws. Slide the access cover down and then pull
the bottom of it away from the spa. Be careful not to
damage the spa shell as you remove the cover.
If the spa will be stored for any period of time, place
the power cord inside the spa before re-attaching the
access cover.
To reattach the access cover, insert the top of the
cover under the edge of the spa shell. Slide the cover
up until the bottom of the cover clears the trim along
the bottom of the spa. Slide the cover into place and
re-attach it with the two access cover screws.
