Congratulations on your purchase of a Far Infra-Red (FIR) Dry Sauna from Keys Backyard. Please take a
moment to read through some of the features and benefits of your new sauna. And remember to always
consult your physician before beginning any sauna therapy program.

HOW IT WORKS – Your sauna uses ceramic rods to produce beneficial infrared rays. This means that a
metallic filament inside the ceramic has an electrical current pass through it. The filament heats the ceramic
surrounding it, and the ceramic rod emits Far Infra-Red rays.
WHAT ARE FAR INFRARED RAYS – Infrared is an invisible band of light that warms objects without warming
the air between them. These are the beneficial rays that our Sun produces, helping to warm our skin with
direct sunlight even on a cold day. With our ceramic emitters up to 95% of the energy produced is
transformed into Far Infra-Red
rays with a wavelength of 5 to 17
microns. The Sun produces
Far Infra-Red rays at 9.4
microns.
ARE INFRARED RAYS SAFE – Infrared rays are essential to almost every form of life on our planet. In
addition to helping warm a person, they also help the body function better on a cellular level. The technology
is so safe that it has been used for years in hospital delivery rooms to help newborn babies achieve an
acceptable body temperature.
REMEMBER:
Your sauna is NOT a hot
box. The infrared
emitters are designed to
heat you, not the air
inside the box.
HOW TO USE YOUR SAUNA – Turn the sauna on and set the temperature to 140 degrees. You will want to
wear a minimal amount of clothing into the sauna as some materials will absorb the infrared rays. Some
people prefer to have some water with them to help replace the water that will
be lost through perspiration. After about 5 minutes your sauna is ready to
use. REMEMBER – your sauna is NOT a hot box. The infrared emitters
are designed to heat you, not the air inside the box. The temperature gauge
is there merely as a guide for your enjoyment and safety.
NOT A HOT BOX – When people hear the word sauna they typically think of
a steam sauna where high temperatures and high humidity induce a person to
sweat. In our example, a steam sauna is similar to a conventional oven. It
cooks your food by heating it to extremely high temperatures. An infrared sauna is more like a microwave
oven – it produces energy which warms the food and excites the water molecules inside the food to bake it.
Your infrared sauna produces energy that will warm your body and cause the desired reactions without having
to reach extremely high (and uncomfortable) temperatures inside the unit. Because of the infrared rays
produced, sweating inside an infrared sauna will start at much lower temperatures than under normal
conditions.
TEMPERATURE – The key to your infrared sauna is to keep the unit working the entire time you are inside.
Working is defined as having a current sent through the filament, which thus produces infrared rays. If you
wait until your sauna approaches or reaches its peak capacity of 140 degrees, the unit will only “work” (emitted
infrared rays) when the temperature drops below 140, which means that you will only intermittently be
receiving the beneficial infrared rays. The temperature gauge and the timer are mandated safety features to
make sure that someone does not overheat their body. There are no negative side effects to prolonged
