PLEASE READ AND FOLLOW ALL INSTRUCTIONS.
DANGER- Risk of drowning
DANGER – Risk of Accidental Drowning. Extreme caution
must be exercised to prevent unauthorized access by
children. To avoid accidents, ensure children cannot use this
hot tub unless they are supervised at all times.
WARNING: Hot tub covers are equipped with clip tie-
downs or snap locks. There is no representation the cover
tie-downs or snap locks will prevent access to the hot tub.
Cover locks are to discourage unsupervised children from
entering the hot tub and to secure cover in high-wind
conditions.
WARNING: DO NOT USE SPAS OR HOT TUBS UNLESS
ALL SUCTION GUARDS ARE VGB COMPLIANT AND
INSTALLED TO PREVENT BODY AND HAIR ENTRAPMENT.
• Risk of drowning or injury. The suction ttings in this hot
tub are sized to match the specic water ow created by
the pump. Should the need arise to replace the suction
ttings or the pump, be sure the ow rates are compatible
and the replacement cover is VGB compliant. (Virginia
Graeme Baker Pool and Spa Safety Act) Never operate
hot tub if the suction ttings are broken or missing.
Never replace a suction tting with one which is not VGB
compliant or rated less than the ow rate marked on the
original suction tting.
DANGER- Risk of injury
WARNING – To reduce the risk of injury:
• The water in a hot tub should never exceed 40°C
(104°F). Water temperatures between 38°C (100°F) and
40°C(104°F). are considered safe for a healthy adult.
Lower water temperatures are recommended for young
children and when hot tub use exceeds 10 minutes.
• Pregnant (or possibly pregnant) women should consult
with their physician before entering
• Since excessive water temperatures have a high potential
for causing fetal damage during the early months of
pregnancy, pregnant or possibly pregnant women should
limit spa water temperatures to 38°C (100°F).
• Before entering a hot tub, the user should measure the
water temperature with an accurate thermometer since
the tolerance of water temperature-regulating devices
varies.
• The use of alcohol, drugs, or medication before or
during hot tub use may lead to unconsciousness with the
possibility of drowning.
• Obese persons and persons with a history of heart
disease, low or high blood pressure, circulatory system
problems, diabetes, or any condition requiring medical
treatment should consult a physician before using a hot
tub.
• Persons using medication should consult a physician
before using a hot tub since some medication may induce
drowsiness while other medication may affect heart rate,
blood pressure, and circulation.
• Do not use hot tub immediately following strenuous
exercise
• Individuals with infectious diseases should not use a spa
or hot tub
• Please use caution when entering or exiting spa or hot tub
• Prolonged immersion in spa or hot tub may be hazardous
to your health
• Never jump or dive into you hot tub
DANGER- Risk of Hyperthermia
• WARNING: Prolonged immersion in hot water may
induce hyperthermia. Hyperthermia occurs when
the internal temperature of the body reaches a level
several degrees above the normal body temperature of
98.6°F (37°C). The symptoms of hyperthermia include
drowsiness, lethargy, and an increase in the internal
temperature of the body. The effects of hyperthermia are:
• Unawareness of impending hazard;
• Failure to perceive heat;
• Failure to recognize the need to exit the hot tub;
• Physical inability to exit the hot tub;
• Fetal damage in pregnant women;
• Unconsciousness and danger of drowning.
WARNING: THE USE OF ALCOHOL OR DRUGS CAN
GREATLY INCREASE THE RISK OF FATAL HYPERTHERMIA
IN HOT TUBS OR SPAS.

6| NORDIC HOT TUBS | OWNER’S MANUAL
There are several items to consider before deciding on a
location for your new hot tub. We’ve listed a few of them
below.
1. PERMISSION: your state, province, city, township, or
association may have rules related to access, construction
permits, fences, gates, and delivery methods and routes.
Please check with them to make sure your plans meet
their criteria. Don’t forget to look for power lines if a crane
needs to place the hot tub on a raised location.
2. SUPPORT: It is extremely important the base on which
the hot tub is placed is smooth, level, and can uniformly
support the complete weight without settling or shifting.
If these requirements are not met, possible damage to
your cabinet or tub shell may result. Damage caused by
improper support is not covered under warranty. It is the
responsibility of the hot tub owner to meet these require-
ments and to assure the integrity of the hot tub support at
all times. A level concrete slab or a well-supported wood
deck (built to code) is ideal.
3. DRAINAGE: Don’t forget the water will occasionally need
to be drained. Make sure that you don’t have sensitive
vegetation or erosion concerns. A regular garden hose
can be attached to the drain tting so the old water can
be directed to an appropriate area. A small submersible
pump can also be used. Also, make sure rain water and
snow melt is directed away from the base of your new hot
tub. External water damage from ooding may damage
the electronics and pump which will void your warranty.
4. ACCESS: if you have decided to drop your new hot tub
into a deck (which looks great and makes it easy to get
in and out of), you will eventually need to remove the
service panel (on the same side as the topside control) to
access the drain or the equipment pack. You can provide
access via a lift-out section of the deck or position the
access panel at an outside edge of your deck. Check with
your builder for additional ideas they may have.
5. THE PATH: a nice clean path is best so sand, mud, and
grass clippings aren’t tracked into your new hot tub.
Tracked-in dirt makes keeping the water sparkling clean
and properly balanced a challenge.
6. THE VIEW: take things like the intended use and number
of users into consideration. If it is intended for relaxation
or a quiet night for 2, then a cozy corner with the view of
a lake or mountain, etc. would be great. Don’t forget to
take the view of your neighbors into consideration as well.
If it will be used for play time for the kids and their friends,
make sure to leave plenty of room around it for climbing
in and out and access to toys.
7. THE WEATHER: if you live in a Northern region like we
do, it is a great idea to place the hot tub close to a door-
way to reduce your time in the cold and snow.
NOTE: Please keep your hot tub covered whenever it is not
being used- especially when it is empty. The shell surface
can be damaged if it is left dry and exposed to direct sun-
light.

DTS ™ NORDIC STAR ™ WHIRLPOOL JET(S):
Your hot tub is equipped with at least one Whirlpool Diverter jet (2, 3 or 4 positions depending on tub model purchased),
located on the lter wall on most models. These jets, when turned, will divert water to either the Whirlpool Jet or to different
groups of wall jets. Each position is reached with a 90 degree turn of the whirlpool jet face. It is recommended to turn the
collar of the whirlpool diverter jet while the jets are in low speed operation and turn clockwise when possible. Remember,
turning your diverter will affect the ow of water to different seat jets. Turn the whirlpool diverter to see which jets turn on/off
in each position and adjust to suit your personal needs.
2-WAY DIVERTER:
With a 2-way diverter the whirlpool jet will either be on or
off. If the whirlpool jet is on, the ow to the wall jets will be
off and all the water will ow out of the whirlpool jet. If the
whirlpool jet is turned off, the ow will be diverted equally
to all the wall jets in the tub.
4-WAY DIVERTER:
With a 4-way diverter, the whirlpool jet will either be on
or off. The other (3) positions direct water ow to different
groups of wall jets depending on which model you have.
If the whirlpool is on all the ow goes thru the whirlpool
and all wall jets are off. If you turn the whirlpool off you
have 3 options to divert the water.
1. All the wall jets in the tub run equally.
2. Half the wall jets will be on the other half will be off.
3. Half that was previously on in option 2 will now be off
and the half that was off will now be on. Remember the
half that is on/off in option 2 & 3 depends on which
model you own.
4. All of the water will come out of the Whirlpool jet

AIR CONTROLS:
Your hot tub has at least one air control. This air control allows air to mix with the
water which streams out of your jets. Each air control is responsible for a section
of jets or a whirlpool diverter jet. In order for the air control to have any effect,
the jet(s) it controls must be on and have water ow. In extremely cold weather
conditions, it is a good idea to rotate them to the off position when the tub is not in
use to help maintain efciency.
NOTE: Rotate, do not lift.
NORDIC STAR ™ JETS:
There are several water jets which can be individually adjusted to customize the
amount of waterow through each. This feature allows you to create the perfect
experience in each seat. To increase waterow to a jet simply turn the jet counter-
clockwise till you feel a stop in the turn. Jet should be fully open for maximum ow.
To turn a jet off, turn the jet clockwise till you feel a stop in the turn. The jet should
be off. When the jet is turned off you will still feel a trickle amount of water through
the jet for safety purposes.
These jets can be removed for cleaning or replacement by turning them fully
counter- clockwise till you feel the stop and then continue an additional 1/16th
turn to force it past the stopping point. Now the jet insert should be able to be
pulled out.
To reinstall the jet simply align the nipple on the back of the jet with the grove in
the jet housing on the wall, push the jet in and turn clockwise.
TOPSIDE CONTROL PAD:
Your hot tub is equipped with an electronic topside control pad. The topside control pad will allow you to control the speed of the
pump, the light, and the temperature setting, as well as some programming options. Familiarize yourself with the topside control
by viewing the Operation Guide on page 15.
LED LIGHTING SYSTEM:
The LED Lighting System consists of individual light nodes which are in coordination with the LED light housed in the light lens
within the vessel of the spa. The light varies in color and function by pressing the light button. To turn on the system, simply press
the button once. To turn it off, re-press the light button. To change the color or light function, press the light button quickly in
succession. If the light has been off for more than 3 seconds it will resume at the last color setting selected. Certain models may
receive the optional NLP ™ Northern Light Package or the MLP™ Mood Lighting Package. The operation is the same but more
items will be illuminated.
