SECTION 14: MAINTENANCE
The sauna, like a bathroom, should be kept clean and odor free.
Towels or mats should always be used on benches and oor as perspiration otherwise penetrates the soft wood.
Air out the sauna often by keeping the door and vents open when the sauna is not in use. Saunas that are in daily use
should be washed down at least once a week to keep them clean and the air fresh. Duckboard should be removed from
the sauna, the sauna oor mopped and dried in a conventional manner, and the duckboard thoroughly scrubbed and dried
before returning to the sauna room. The sauna heater should be wiped down occasionally with a damp cloth to remove
lint and dust. The rocks should be removed once a year for cleaning and small or crumbled rocks replaced.
To clean and remove perspiration stains, use soap or detergent in warm water, best applied with a scrub brush. Badly
soiled surfaces may require sanding. Sand paper wrapped around a wooden block works well.
Benches and supporting structure must be inspected annually for potential deterioration due to age, dry rot or abuse. Any
boards with signs of deteriorations should be replaced immediately to avoid possible injury.
BWT will accumulate hard-water scale inside the tank as the water is evaporated over time. The water scale will not
immediately affect performance. It is recommended to remove the tank from the heater and clean it when you notice a
heavy accumulation or when the rocks are changed. Simply tap on the sides of the tank to loosen the scale and then
dump into a waste basket. If stubborn scale accumulation remains, you may use any commercially available de-scaling
product to remove built-up hard water scale. Follow up with a fresh water rinse before putting BWT back into the heater.
SECTION 12: VENTILATION
VENTILATION In a sauna, the air should be changed about 6 times an hour. This can be achieved by making a vent
opening (fresh air inlet) in the sauna wall directly below the heater. The air outlet must be lower than the upper benches,
as far as possible from the heater and about two feet higher than the fresh air inlet vent, See Diagram 9. It is
recommended that ventilation openings meet the requirements of UL Specication 875. The minimum opening should
be determined using one of the following formulas:
For R< 31, V
³
9.3, For R
³
31, V
³
0.3R
where R = the oor area of the room in square feet and
V = the minimum vent size in square inches
SECTION 13: BWT (Bio Water Technique) Technology
The world sauna trend is moving towards higher humidity and lower temperatures. Many nd it easier to breathe, the
skin feels warm, and the humidity helps induce a sweat. This system will increase the humidity in the room allowing the
air temperature to be lower, and still feel hot.
BWT technology provides the ability to increase humidity levels in the sauna room while the heater is warming up and
during the sauna session. The continuous soft boil of water during the sauna session increases the humidity in the room
to provide a consistent feel. Additional water can be added to the rocks to provide an additional spike of humidity as
needed.
How to use BWT:
Allow heater to warm up for approximately 20 minutes and add water into the tank through the side of
fragrance diffuser with slots. Add approximately 2 cups of fresh water into the tank. Do Not Use Pool or Spa Water.
Fragrance oils can be placed in the side of the fragrance diffuser without the slots. Avoid adding fragrances directly into
the water of the BWT. The oils may cause the water to foam and maybe difcult to remove the scent from the tank.
BWT tank and sleeve should always be installed in heater with rocks. Water in the tank is optional and not required if
preference is lower humidity.
