WINTERIZING YOUR HOT TUB
28
| NORDIC HOT TUBS | OWNER’S MANUAL
While we feel some of the best times to use your spa can
be during the colder months, we understand there can
be a need for some owners to close their tubs during the
winter months. We feel winterization should be left to the
professionals, but if done carefully using the following
instructions, your risk of damage from freezing can be
minimized. Please note, we do not warrant against freezing
damage in a tub which has been inappropriately winterized,
either by the owner of by a professional service center.
WINTERIZING INSTRUCTIONS
Things that will be needed:
• 2-3 gallons of NON-TOXIC (R-V type) antifreeze
• a strong wet/dry vacuum (shop vac)
• a turkey-baster
• 1 or 2 light plastic bowls approximately 5” diameter
• TIME approx. 2 hours
Instructions
1. Drain your tub. Inside the equipment room there is a
spigot for a garden hose. It is attached to a clear vinyl
hose near the main control box.
2. With a wet-vac, remove any water remaining in the foot-
well. Then with each jet in the open position, vacuum
each jet nozzle until no more water comes out. DO NOT
FORGET the small ozone jet in the foot-well.
3. With the vacuum over the whirlpool jet nozzle(s) and
plastic bowls over the suction covers in the footwell,
change it to each diverter position until there is no more
water being drawn out.
4. Remove your filter, clean it and place in storage until you
restart your tub. Pour NON-TOXIC antifreeze into the
filter canister until it runs out into the foot-well of your tub
through the suction covers.
5. With the turkey-baster, squirt a small amount of NON-
TOXIC antifreeze into each jet. Usually the side jets will
take around one ounce, and the whirlpool jet(s) will take
several ounces (about 5 squirts per whirlpool jet). DO
NOT FORGET the small ozone jet that is located in the
foot-well of your tub.
6. Place the cover on the tub, and place a tarp over the tub
and cover. Making sure to securely tie down the tarp. The
tarp will help reduce the amount of weather your tub is
exposed to.
A couple of things you should be aware of:
When a tub is drained and left empty, o-rings and pump
seals can dry out and lose their ability to seal properly. You
should closely inspect for small leaks in the equipment
area when you perform your restart. If you are unsure of the
location of the o-rings and pump seal, contact your dealer
for help. If replaced early the damage caused by these
failures can be inexpensive to fix.
RE-START
When restarting your tub, you will want to fill the tub and run
all of the jets on high speed for 10-15 minutes. This will help
flush the residue of the antifreeze out of the plumbing. Then
drain the tub, clean the sides with an approved cleaner,
place your filter back into the filter canister, re-fill your tub
and balance your chemicals.
You may notice slightly more foaming than normal when
you first start using your tub, this can be reduced with anti-
foaming agents and generally gets better over the first week
or two of usage as the filter removes the anti-freeze and
organic residue left behind after rinsing and cleaning.
Make sure you check your filter at least once per week and
rinse it out as needed for the first few weeks. You may also
find it necessary to soak your filter in a filter cleaner after a
few days, depending on the level of contaminant left in the
tub after the re-start.
