SYMPTOM: THE SPA JET UNIT CAVITATES
DURING USE
a. Adjust the water level. This usually occurs only
when the water level is low. Add water until the
filter and jets are covered.
b. This problem is caused by excess air in the
pump circulation system. Check to see if the
primer cap is fully tightened. Prime the pump
again and fully tighten the primer cap (see
PRIMING THE SPA JET UNIT on page 10).
c. Make sure that the through-the-wall connectors
are tight.
10 SYMPTOM: THE WATER IS NOT BEING
CLEANED BY THE FILTER
a. Check to see if the filter is in place. Clean the
filter if it is dirty.
b. Check the chemical balance of the water. If the
pH is incorrect, the sanitizing agents will not
function properly.
11. SYMPTOM: THE SPA JET UNIT CONTINUES
TO RUN AFTER IT HAS BEEN SHUT OFF
a. The spa jet unit features an automatic mode,
which heats and filters the water when the spa
is left unattended. When the spa jet unit is first
plugged in, or if the on/off button on the con-
sole has not been used for longer than twenty
minutes, the automatic mode will begin filtering
or heating the water, as needed. To keep the
filter and heat cycles from running, the power
cord must be unplugged.
Note: If the unit is to
be kept outdoors in cold weather, you must
allow the spa to maintain a safe temperature
by running in automatic mode. Allowing the
spa jet unit to freeze will damage the unit. If
you do not want to use the spa during the
winter, store it in a warm, dry location (see
WINTER USE AND CARE on page 13).
12. SYMPTOM: THE WATER LEVEL DROPS
a. Some water loss due to evaporation is normal.
If rapid water loss occurs, or if you notice wet-
ness on the floor around the RENEW 815, then
the liner may have a leak. Locate the leak, and
patch it using a pool patch kit that you can pur-
chase at any pool and spa supply store.
b. A clamp or seal inside the spa jet may be
loose. Check the floor around the spa jet unit
for excess water, and watch the spa jet unit
while it is operating to see if water drips from
the spa jet unit housing. If you can identify the
location of the leak inside the spa jet unit, tight-
en the clamp or replace the damaged seal.
13. SYMPTOM: THE INFLATABLE SPA LINER
LOSES AIR
a. Over time, some air loss is normal. If rapid air
loss occurs, then the liner may have an air
leak. Locate the leak, and patch it using a vinyl
patch kit that you can purchase at any pool and
spa supply store.
14. SYMPTOM: THE SPA PUMP LOSES ITS PRIME
a. Make sure the threaded collars connecting the
dry side jet pack to the wet side jet pack are
completely tight.
