5. Attach drain hose to garden hose and direct to an
appropriate draining area. Maintain hose below water
line.
6. After your spa is empty, clean the shell and filter car-
tridge (see instruction on page 10).
7. After cleaning, remove garden hose and put drain
cap back in place.
8. Replace the equipment compartment access door.
NON-OPERATION IN COLD CLIMATE
If the spa is to be left unused for an extended period of
time in areas where FREEZING TEMPERATURES DO
NOT OCCUR, it may be desirable to turn the heater to the
lowest temperature. The automatic filter cycles will keep
the spa water clean and sparkling. When preparing the
spa for use, check the water chemistry to assure correct
chlorine or bromine and pH levels.
Consult your
Chemical Handbook.
You can keep the water in the spa during the time of year
when freezing at the spa location may occur. If a freeze
condition is detected, the pump and heater will be acti-
vated automatically to circulate the water in low speed.
However, CAUTION must be used with this approach. In
the event of electrical power interruption, regardless of
the cause, the heater and pump will stop operating and
freeze protection will be lost, possibly resulting in freeze
damage to the spa, spa plumbing and/or components.
Such damage is not covered by warranty.
WINTERIZING YOUR SPA
If the spa is located where freezing temperatures occur,
and you do not intend to use your spa for an extended peri-
od, follow steps 1 through 7 outlined in “DRAINING YOUR
SPA” on page 10 then complete the following steps:
NOTE: Make certain all power to the spa is OFF and all
water has been drained from the spa before you continue.
1. Use a wrench to remove the Pump Drain Plug located
on the front of the pump housing. Allow all water to drain
out, then replace the Pump Drain Plug.
2. It is necessary to
remove all water
from interior
plumbing. Remove
the two screws
securing the suc-
tion cover, then
remove the suction
cover.
3. Close the suc-
tion with a 1 1/2” NPT “freeze plug” (available at your local
hardware store). Then use a shop vacuum to blowout the
water by inserting the hose in the bottom of the filter can-
ister forcing water back through the jets.
WARNING: When not in use, the spa must be covered
with an insulating spa cover. Damage caused by either
sun exposure or freezing is not covered under warranty.
