WATER CHEMISTRY
The hydrotherapy spa comes with a starter chemical
pack for maintaining the water in the spa. (See TEST-
ING AND TREATING THE WATER on page 11.)
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 to do 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.
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 RENEW 207.
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, test the pH of the
water regularly. You will need a pH test kit (not includ-
ed), 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.
REMOVING AND ATTACHING THE ACCESS COVER
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 unit.
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 unit 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 unit. Slide the cover into place
and re-attach it with the two access cover screws.
DRAINING THE RENEW 207
The RENEW 207 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 it will not be used for long
periods of time. The spa must always be drained
before major repairs are made.
The RENEW 207 should always be covered when
it is empty. Direct sunlight can cause extensive
damage. The surface of the spa shell can reach
temperatures as high as 150¡ F in a matter of min-
utes if exposed to the sun while it is empty. These
high temperatures can cause significant damage,
such as blistering of the shell surface and warp-
ing of the spa shell. Any damage caused by sun
exposure is not covered under warranty.
