A true dedicated outlet is an outlet that runs from the wall outlet to the breaker
box with its own switch in the breaker box and nothing else on that line.
Plugging your sauna into your wall outlet with any other electrical device is not
a true dedicated outlet and will hinder the sauna’s ability to warm up properly.

WARM UP TIME AND USAGE GUIDELINES
The controls are preset to 60 minutes at 150°F. However, the inside cabin
temperature is not intended to reach this. Our saunas are based on the infrared
wavelength and not cabin temperature. Allow the sauna to warm up for 30-45
minutes. The sauna heats up at an average of 1 degree per minute. Follow
these steps for proper warm up:
Step 1: Make sure your sauna is plugged into a dedicated outlet installed by
your electrician.
Step 2: Check the settings on the keypad. The default setting should be set to
150 degrees and the timer set to 60 minutes.
Step 3: When turning sauna on for the first time, ensure each heater is warming
up after a couple of minutes. If they are not, make sure connections are securely
connected.
NOTE: If your sauna is outside or in an unheated garage, sun room, basement or
patio, you may require additional time to warm the sauna up depending upon the
temperature of the surrounding surface & room. Keep in mind you are required to
have an authorized Sunlighten cover over your sauna if it is outside or exposed to the
weather in order to maintain your warranty.
RESERVATION MODE
1. Turn off the sauna
2. Press the timer up and timer down arrows simultaneously
3. A digit will appear on the timer section of the screen to indicate the number of
hours before the sauna turns on.
4. When the timer counts down to “0,” the sauna will turn on for a 60 minute
session and will be set to 150 degrees.
To cancel a reservation, press and hold the power button until the time display
turns off. At this point you can turn the sauna on normally.

SAUNA PROTOCOL
Follow this quick guide for the optimal sauna experience.
PRE SAUNA SESSION
• Hydrate with at least 8 oz. of water to prepare your body for an increase
in core temperature.
• Pre-heat for approx. 30 minutes. Depending on room temperature, your
sauna will heat up a degree per minute.
• Use Bamboo Carbon Towels to absorb sweat during sessions.
SAUNA SESSIONS
• Begin your session when your sauna reaches 100°F.
• The optimal sauna experience occurs between 100° and 130°F.
• To get your body accustomed to infrared therapy, start with 10-15
minute sessions at 100°F every other day.
• Gradually increase towards 40 minute daily sessions in the optimal
temperature range.*
• Don’t be surprised if you don’t sweat during the first few sessions.
Sweating will increase with regular use, removing toxins and leaving you
feeling refreshed and rejuvenated.
• For added intensity, use Pure Sweat amplifying cream to increase
sweating, circulation and to boost results. Post Sauna Session
POST SAUNA SESSION
• Drink at least 24 oz. of water or electrolyte to rehydrate.
• Dry off with Bamboo Carbon Towel. Cool down naturally or with a
refreshing shower.
• Every six months, clean wood and glass with our Natural Sauna
Cleaning Kit. Available at store.sunlighten.com.
*Listen to your body. Be aware of excessive detoxifying. If you begin to feel symptoms such as nausea,
fatigue, or flu-like symptoms during your sauna session, discontinue use immediately. If these
symptoms continue, consult your physician.

HEALTH & SAFETY
Our infrared saunas operate with the same efficacy in your home as in a medical
facility. Like all professional equipment, you may put yourself at risk if you do
not fully understand how to use the sauna. Infrared sauna use as creating a cure
for or treating any disease is neither implied nor should be inferred. Drinking an
electrolyte-replacing water or a sports drink is strongly recommended before
and after use.
Important Safeguards
• Never sleep inside the sauna while it is on
• Do not use harsh cleaning agents on the interior of the sauna
• Do not stack or store objects on top of or inside the sauna
• Do not use during an electrical storm, as there is a remote risk of shock
• Altering or tampering with any electrical connections on the power supply
is dangerous and will void the warranty

FREQUENTLY ASKED QUESTIONS
ASSEMBLY
Can I assembly my sauna outdoors?
Yes, if you protect it with a Sunlighten canvas sauna cover. If you place your sauna
outdoors without a Sunlighten cover, your warranty will be void. The sauna covers are
custom made and may not arrive until after you receive your sauna. Do not install your
sauna outdoors prior to receiving your cover. Doing so will void the warranty! Check
the sauna cover annually for normal wear and replace as needed.
How much room is required around my sauna for set up and maintenance?
We recommend 4-12 inches of clearance around the back, sides and top of the sauna
to access plugs and for general maintenance. Leave at least 4 inches behind the unit to
allow the electronics to cool.
What surfaces can I set my sauna on?
You can set your sauna on tile, concrete, carpet, laminate or wood. Remember to make
sure that your sauna is level regardless of its location for optimal use. If your sauna is
placed outdoors , make sure there is adequate drainage so that water cannot pool
around the base of the sauna. If placed near or on cool surfaces (like concrete and
basement walls), warm-up can be impacted.
How do I install Chromotherapy and Acoustic Resonance Therapy?
These are add-on sauna accessories with separate user manuals. Please refer to the
appropriate manual.
USAGE
How long does it take for my sauna to warm up?
The controls are preset to 60 minutes at 150°F. However, the inside cabin temperature
is not intended to reach this. Our saunas are based on the infrared wavelength and not
cabin temperature. Allow the sauna to warm up for 30-45 minutes. The sauna heats
up at an average of 1 degree per minute. If located outside or in unheated garage,
additional warm up time may be required. If you prefer the sauna hotter, let it warm up
longer.
Can I use my sauna every day?
For the majority, daily sauna use is okay after your body has become accustomed to
infrared therapy. Drinking increased amounts of water to stay hydrated. Listen to your
body and stop your session if you feel any discomfort.

19
How long can I use it for each day?
40 minutes is the recommended session length. See the sauna protocol on page 14.
What is the best temperature to use my sauna?
First, it is important to understand that health benefits are a result of efficient infrared
emissivity, not air temperature. Sunlighten saunas are 95-99% emissive and deliver the
highest concentration of infrared. With that, the optimal sauna experience occurs between
100-130°F. During your first few sessions, start at a lower temperature of 100°F and
gradually increase in later sessions. Everyone has different preferences and tolerances for
heat. The most important thing is to listen to your body. Keep in mind, if you’re sweating
at 115°F you’re getting the same benefits as if you’re sweating at 150°F.
What is the micron range of the heaters?
The sauna puts out a wide micron range of 4 - 20 microns.
Can I touch the heaters?
While using, the heaters are safe to lean on with heater cover intact. Do not touch the
bare heater surface when the heaters are on, or have recently been on.
What is the heater made of?
The heater is made of organic black carbon that is first cut into pliable sheets. Then
electrical wiring is added.
How much will the sauna cost to run a month?
The sauna runs on the same wattage as a blow dryer and will cost very little to run
monthly: typically 15 to 35 cents per hour. This varies with model and your local utility
cost. Your utility company can help you understand a more exact per hour cost if needed.
Are the EMF levels safe?
Yes. Patented Solocarbon® panels are 100% quality controlled by Sunlighten™ to
ensure the safety and effectiveness of each individual heater. Our proprietary heater
design virtually eliminates EMF (an average of less than 3mg) and steel conduit electrical
shielding making your sauna as safe as possible. View Solocarbon EMF testing data at
www.sunlighten.com/emf
What is the wattage, voltage, and amps of my sauna?
See electrical specifications on page 4.

20
Why do you recommend using Bamboo Carbon towels?
Bamboo Carbon towels will make your sauna experience more comfortable and will
keep the sauna clean. Bamboo Carbon is anti-fungal and deodorizing, emits infrared
rays and is highly absorbent. Use on the bench, floor and backrests for optimum comfort
and cleanliness. Bamboo Carbon towels can be purchased at store.sunlighten.com.
MAINTENANCE
How do I clean my sauna?
Sunlighten’s Natural Sauna Cleaner is made specifically for use with your sauna. At least
every six months, dampen cloth with Sunlighten All Natural Wood Cleaner. Clean glass
door and windows with Sunlighten All Natural Glass Cleaner. You may dust the outside
of the sauna with a dry dust cloth. Do not use chemical cleaners on your sauna. Light
sandpaper can be used to treat stains on the inside of the sauna. Sunlighten Natural
Sauna Cleaning Kit can be purchased at store.sunlighten.com.
How do I care for the heater fabric?
The heater fabric remains as a covering over the heater panels. This is to protect the
heater surfaces from any scratches, etc. It is also there to prevent physical contact
between the skin and the heaters as the sauna is being used. To clean, wipe fabric with
slightly damp cloth. We recommend doing so at least once every six months. Only do so
when sauna is turned off.
Is it normal to see cracks in the wood?
Yes, wood is a living material that continues to respond to climate conditions, even
after being manufactured into a sauna. During normal operation, wood may crack
slightly due to changes in moisture level. These cracks may appear or disappear with
the changing seasons, but will not affect the structural integrity of the sauna. Our saunas
are shipped around the globe, and can experience slight blemishes, scratches, or
scuffs from the transit of this sauna. In most cases these blemishes on the exterior of
the room can be concealed by using a small amount of furniture polish, oil, or other
furniture treatment. The interior blemishes, scratches, or scuffs can be either left alone,
sanded, or combination of gluing and sanding. Please avoid any treatment containing,
benzene, or a high concentration of alcohol. However, if you detect major cracking or
damage that jeopardizes the functionality of your sauna, please submit pictures to at
www.sunlighten.com/support.
