The hydrotherapy spa is designed to provide years of
enjoyment. Please follow the guidelines below to
properly maintain your spa.

MAINTENANCE SCHEDULE

Daily

¥ Check the water level and refill the spa to the level

shown in step 3 on page 9.

¥ Check the pH balance and sanitizer level. Adjust if

necessary (see WATER CHEMISTRY on page 14). 

¥ Clean the surface of the water with a skimming net.

Weekly

¥ Clean the spa shell at the waterline. 
¥ Check and thoroughly clean the filter (see CHECK-

ING AND CLEANING THE FILTER on this page).

¥ Replace the filter if needed (see ORDERING

REPLACEMENT PARTS on the back cover).

Monthly

¥ Clean the spa cover (see MAINTAINING THE SPA

COVER on this page).

¥ Soak the filter for two hours in a trisodium phos-

phate (TSP) solution. Rinse the filter in clean water.

¥ Replace the filter if needed (see ORDERING

REPLACEMENT PARTS on the back cover).

Every Three Months

¥ Drain the spa and refill it with clean water. Sanitize

and test the pH of the water. 

¥ Check for any leaks around the pump or joints in

the pipes. The seals will wear out over time; detect-
ing leaks early can reduce repair costs.

¥ Clean the interior of the spa. Do not use solvents or

waxes.

Every Six Months

¥ Treat the exterior with a wood sealant (see MAIN-

TAINING THE SPA EXTERIOR below).

MAINTAINING THE SPA EXTERIOR

The WeatherWoodª surround has been treated at
the factory. For information and supplies to maintain
the beauty and color of your WeatherWoodª sur-
round, call our Customer Service Department toll-free
at 1-877-897-7493.

CLEANING THE SPA SHELL

The spa shell should be cleaned with a mild soap
solution; do not use solvents. The spa should always
be clean and dry before being moved or stored.

MAINTAINING THE SPA COVER

The spa cover should be cleaned monthly. To clean
the spa cover, use water and a non-abrasive cleaner
on the entire cover. Rinse the cover with a garden
hose to remove any cleaner residue. Dry the cover
entirely. Use a non-silicone-based vinyl conditioner on
the cover after you clean it. This will help protect the
cover from sun damage.

SANITIZING THE HYDROTHERAPY SPA

Please refer to your local pool and spa supplier for
information concerning which chemicals you should
use in your area to sanitize the spa.

The most common sanitizing agent is a solid bromine
concentrate. The amount required varies according to
several factors, such as user load, temperature, water
conditions etc. Proper water maintenance is a fairly
complex process. We recommend that you contact
your local pool and spa supplier for information on
how you should best accomplish this.

CHECKING AND CLEANING THE FILTER

The filter should be checked periodically for build-up
of dirt and oil. If the filter needs to be cleaned, follow
the steps below:

1. Turn off the power.
2.  Turn the air vent

counterclockwise to
open it. 

3. Unscrew the locking

ring and pull out the
filter cover.

4. Lift the top filter gas-

ket and the filter out
of the filter housing.

5. Check the filter for

dirt and debris. If the
filter needs to be
cleaned, rinse the fil-
ter with a hose. If the
filter is still dirty, soak
it in cleaning solution
from a pool and spa
supply store.

6. Inspect the filter for

damage. Replace the filter if it is damaged.

7. Insert the cleaned or new filter and the top filter

gasket into the filter housing.

8. Re-attach the filter cover and the locking ring.
9.  Turn the air vent clockwise to close it.
