WATER CHEMISTRY
The RESTORATION 2.0 comes with a starter chemi-
cal pack for maintaining the water in the spa. (See
TESTING AND TREATING THE WATER on page 10.)
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 chemicalsÑfollow the directions on the
label closely.
4. Keep all chemicals out of the reach of chil-
dren and pets.
5. Keep all containers closed tightly when
not in use.
6. Never add water to the chemicalsÑalways
add the chemicals to the water as directed.
7. Always store chemicals in a cool, dry
place.
8. Always keep chemicals away from chil-
dren and pets.
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 RESTORATION
2.0.
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. You will need a pH test kit
(not included), which can be obtained at a pool and
spa supply store. 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 minutes. See the instructions with your
pH test kit for additional information about testing and
adjusting the pH.
ATTACHING AND REMOVING THE ACCESS
COVER
To remove the access cover, remove the two cover
screws from the access cover. Slide the access cover
down and pull the bottom of access cover away from
the Spa Unit. Be careful not to damage the spa
shell as you remove the cover.
To replace 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 will clear the trim
along the bottom of the spa unit. Slide the cover into
place and re-attach the two cover screws.
If you will be storing the spa for any period of time,
you should place the power cord inside the spa unit
before re-attaching the access cover.
DRAINING THE RESTORATION 2.0
The RESTORATION 2.0 should be drained at least
four times a year and refilled with clean water. You
may need to drain the spa more often, depending on
the user load. This must be done, because after
repeated chemical treatment, the water becomes
chemically saturated. Once this happens, additional
chemical treatment of the water is no longer effective.
The spa should also be drained if you will not be
using it for long periods of time. The spa must always
be drained before major repairs are made.
The RESTORATION 2.0 should always be covered
when it is empty. Direct sunlight can cause exten-
sive damage. The surface of the spa shell can
reach temperatures as high as 150¡F in a matter
of minutes if exposed to the sun while it is empty.
These high temperatures can cause significant
damage, such as blistering of the shell surface
and warping of the spa shell. Any damage caused
by sun exposure is not covered under warranty.
To drain the RESTORATION 2.0, follow these steps:
1. Set the temperature control on the console to the
lowest setting.
