Shock Treatments (Potassium Peroxymonosulfate); Water Testing; Stain And Scale Inhibitor; Foam Inhibitor - L.A. Spas 2010 North American Owner's Manual

SHOCK TREATMENTS (POTASSIUM PEROXYMONOSULFATE)

Even with regular sanitization, shock treatment may be necessary on occasion. Shock is recommended
over super chlorination because it does not add additional sanitizer to the water. It is also effective in
oxidizing wastes and will reduce chloramines or bromamines. Follow the manufacturer's instructions
listed on the label.

WATER TESTING

It is recommended that you test your spa water regularly with an accurate test kit or test strip. These are
available from your local authorized L.A. Spas dealer. Be sure to follow the chemical manufacturer's
instructions for chemical use.

STAIN AND SCALE INHIBITOR

Staining and scaling may be a common problem in spas. Because the water is hot, scale may be
deposited more quickly. The circulation of water can cause the erosion of metals from spa equipment,
which can stain interior surfaces. A weekly dose of a stain and scale fighter will help control these
problems.
A sequestering agent, such as Metal Gone, can be added to the spa water when filling a spa (for the first
time or when draining and refilling). This will help eliminate metals in your water and increases the life of
your spa equipment.

FOAM INHIBITOR

Soap residue from a user's body, hair, and swimsuit combined with rapid circulation of spa water may
cause foaming in your spa. Foam inhibitors will suppress foam, but cannot remove soap from the water.
When foaming occurs, a shock treatment can oxidize the soap in your water and help prevent this
condition. If foam remains a problem, change the water. Consult the directions on the foam inhibitor
container for usage amount. When adding chemicals to your spa water, add to the center of the spa
with the pump and air blower (if equipped) operating simultaneously. Never add chemicals directly into
the skimmer. Make sure the water is heated. Never add chemicals to cold water, as this will affect the
chemical reaction.
Store all chemicals in a cool dry location and in such a manner to prevent contact by children or pets.
You should consult your local authorized L.A. Spas dealer prior to any chemical use.
